原書表記

What makes a spell “artillery” is that it can quickly injure more than one opponent per casting. This admits significant variation.

The spell might have multiple enemies as its subjects, and inflict direct injury on them like a Deathtouch, Dehydrate, or Frostbite spell writ large. The subject may instead be an area, which fills with a noxious substance or energy (similar to a “Rain of” spell). Or the subject could be the caster, who is empowered to emanate or hurl something destructive (Explosive Fireball is a prime example) – or even an item that radiates a harmful effect.

Some artillery is more insidious. It might mind-control victims into attacking (like a special-purpose Charm spell) or levitate a blade and start slashing (like Winged Knife). In those examples, although people or objects are the subjects, ultimately weapons – not magic – are the immediate cause of any damage done.

In all cases, injury is likely to occur in a manner consistent with the spell’s college; e.g., Fire magic burns, whether flames rain down over an area or the caster projects them, while most Movement magic involves kinetic threats, whether it’s victims or objects that hurtle through the air. See A Congregation of Colleges (p. 6) for ideas.

The main differences are defenses. Against spells cast directly on subjects, this tends to mean high attributes, Magic Resistance, or suitable countermagic. Against spells that damage via dangerous energies or substances, it may be possible to dive for cover – or to dodge or block – and DR or more-specialized protection (such as Resistant to Poison vs. poison gas) is effective. If the magic is less direct, the counter could be anything; e.g., active defenses against mind-controlled allies.
See The Receiving End (p. 5) for other thoughts.

In short, there are a lot of possibilities! For the GM interested in exploring these – or the player bent on convincing the GM to allow magical research – some guidelines are in order.

Certain spell classes are simply better for artillery.

「[[L-範囲呪文>GURPS Magic: Artillery Spells#Area]]」

原書表記

Area Spells
Of the 50 spells in this collection, 28 are Area spells, and with good reason: The most obvious way for a spell to affect many targets is to blanket an area containing them. Write-ups of Area spells need to be clear about a few important considerations.

First, an Area spell might have as its subject the ground within or space above the area, which it scourges with some injurious effect. If such a spell has a duration longer than “lasts an instant,” it endures in the area. This means it poses an ongoing threat there, but also that people who leave the area escape it – although they may suffer lasting side effects, like being blinded or set alight.

On the other hand, an Area spell might have as its subjects the people in the area at the moment the dice are rolled for the casting; if it’s Resisted, that’s usually the case. If a spell like that endures, there’s no persistent effect in the area. Those who fall prey to it cannot get rid of its effects by leaving the area – they’ll need countermagic – but later arrivals are unaffected.

Next, if the spell is of the kind that affects the people in the area rather than the area proper, the caster can usually leave “holes” for allies (GURPS Magic, p. 11). This makes such artillery nicely selective (though if a friend is in close combat with a foe, the wizard must exempt both or neither – on a battle map, the smallest hole is one hex). If that seems too good in the case of a particular spell, state that it doesn’t work that way. Spells that affect the area rather than the people within it don’t normally extend this option; if such artillery does allow selectivity, that also needs noting.

Finally, an insidious way to have an Area spell affect lots of people is to have its bad effects somehow spill out of the area. Specify exactly how this works. Examples in this grimoire are Creeping Plague (pp. 10-11), which summons vermin that ride victims out of the area; Flammability (p. 26), which renders subjects’ gear dangerously flammable; Mirror, Mirror (pp. 17-18), which conjures phantoms capable of pursuing subjects far and wide; and Stabbing Party (pp. 20-21), which compels subjects to shoot at or violently rush their allies wherever they may be.

「[[L-通常呪文>GURPS Magic: Artillery Spells#Regular]]」

原書表記

Regular Spells

The next-best candidates for artillery are Regular spells. These account for 11 of the 50 offerings in Chapter 2. Most have no range; instead, they give the caster a “weapon” with which to attack multiple opponents.

The most obvious such weapon is a “jet” spell so broad that it can blast everyone in a wedge-shaped area. It might use Cone Attacks (p. B413), as Arctic Blast (p. 27), Cone of Corrosion (p. 27), and Sand Blast (p. 12) all do. However, bursts of projectiles, like Fire Swarm (pp. 14-15), may add complications similar to the Bombardment limitation (p. B111), or work like Spraying Fire (p. B409) instead. Such magic could even allow a jet to strike several targets in rapid succession without an All-Out Attack, as with Sun’s Arc (p. 18).

Another possibility is an effect that uses rules similar to the Emanation limitation (p. B112). Such things are a lot like Area spells – but as they always have the caster as their subject, and thus have zero range, they’re best modeled as Regular. These might persist (like Psychic Scream, p. 12) or be one-offs (like Withering Wail, p. 25).

Yet another option is a spell that makes the caster blow up or otherwise become a weapon. This is a lot like the previous kind of spell, but bad for the caster as well! The only example in this collection is Self- Destruct (p. 23).

Or the spell might be cast on a patch of ground or volume of space no larger than one hex on a battle map, yet endanger an area around this. Such spells do have range; range penalties are to the effect’s point of origin, not to the edge of a fixed area. In most cases, danger tapers off with distance from this source, whether using the rules for explosions on pp. B414- 415 (see Explosive Mine, p. 19) or something more complicated (look at Collision, p. 21). However, an effect that leaves its starting point and lays waste to the surroundings, like Twisting Terror (p. 10), is a welcome, um, twist.

「[[L-射撃呪文>GURPS Magic: Artillery Spells#Missile]]」

原書表記

Missile Spells

Missile spells resemble real-life artillery the most: Long-range attacks that damage distant targets. There are eight examples in this work.

All the existing Missile spells intended as artillery – Ball of Lightning, Concussion, Explosive Fireball, and Explosive Lightning – explode. To improve on these, damage must taper off more gradually than Explosions (pp. B414-415) prescribes. The Explosion enhancement (p. B104) offers a solution: divide damage by less than three times distance in yards from the impact point. Dividing by distance in yards is most dramatic, and is the meaning of “Improved” in Improved Concussion (p. 25), Improved Explosive Fireball (p. 15), and Improved Explosive Lightning (p. 29). Sunburst (p. 18) also does this. Short ranges endanger the caster in such cases, so if Range is less than 50/100, double it – and then add +1 or +2 to Acc to help wizards hit things that far away.

An effect that tapers off with distance doesn’t have to be an explosion. It might work more like a lobbed Area or Regular spell that’s easier to resist for targets farther from the impact point. See Null Sphere (p. 16) for one approach.

A further possibility is to let the Missile engage multiple foes. It might jump between them, necessitating carefully worded rules for engaging successive targets, as Chain Lightning (p. 29) and Force Ball (pp. 24-25) illustrate. To keep it under control, it should lose damage on successive hits (‑1d damage/hit is simplest) and have a total target-to-target travel distance equal to Max. A Missile might instead do full damage to everything along a line, in which case the odds of hitting all but the initial target should be kept low. The rules for overshooting (p. B390) work, and although they might not seem generous, 9 or less means hitting 37.5% of later targets, with the earlier victims providing no cover DR. Either way, don’t add the complication of 1/2D – damage loss per “bounce” or low odds of a full-damage hit replace that rule.

「[[砲の受け手>GURPS Magic: Artillery Spells#Receiving]]」

原書表記

The Receiving End

Artillery spells make a few rules especially important. Make sure “bosses” can exploit these to reduce the threat posed by artillery intended for “cannon fodder”! Heroes expecting to face enemy wizards should also pay attention.

Resisted Area Spells (p. B242): Most artillery spells are Area spells, some of which are Resisted. For these, remember to double Magic Resistance (p. B67), add it to the resistance score, and compare the subject’s margin to the spell’s. Magic Resistance never penalizes rolls to cast Area spells, and doesn’t affect Area spells that aren’t Resisted – or cones, explosions, or other harmful effects not cast directly on the subject. Magic Resistance is excellent protection for non-spellcasting bosses.

Diving for Cover (p. B377): Against an artillery spell that produces a cone – or any Area spell that specifically allows it (most don’t, but a few produce physical effects victims can evade) – it’s possible to roll Dodge at +3 to leap one step in any direction. Defense Bonus, as from a shield, is irrelevant. If the roll succeeds and the step moves the defender out of the area, that person is unaffected; if it succeeds and moves the defender behind useful cover (from a cone’s origin, or overhead against devastation from above), the cover protects normally. Against explosions, success means being a step further from the blast’s center and thus taking less damage. Enhanced Dodge (p. B51) is obviously valuable; Enhanced Dodge (Dive for Cover) [5/level], from GURPS Action 1: Heroes, adds only to rolls to dive for cover. Having Move 11+ to enjoy a larger step (Step, p. B368) is also worthwhile.

Large-Area Injury (p. B400): Except as noted, if a spell generates a cone, an explosion, or a damaging physical effect that fills an area, it delivers large-area injury that ignores hit location, and “effective DR” is the average of torso DR and the DR of the least-protected hit location exposed (which could still be the torso), rounding up. For fantasy warriors, this generally amounts to averaging torso DR and DR 0 over the eyes: halve torso DR and round up. The most effective protection against large-area injury is uniformly good DR; many monsters have Nictitating Membrane (p. B71) to protect the eyes, and DR with Force Field (p. B47) and the Armor spell (p. B253) enable powers and magic to accomplish the same. Spells that inflict “HP of injury” bypass DR and deplete HP directly; normally, the only defense is Immunity (pp. B80-81) to whatever does the harm.

「[[L-その他の呪文クラス>GURPS Magic: Artillery Spells#Everything]]」

原書表記

Everything Else
Melee spells, of which there’s just one offered here (Plague Touch, p. 11), are almost the opposite of artillery in that they have no range and affect one person by touch. Such a spell could make its victim explode or emit harmful emanations, but it’s hard to imagine a thaumatologist smart enough to invent spells being dim enough to develop a curse that puts the caster within at most staff’s length of a mass-damage effect – why not cook up a Regular spell? The most likely justification is thematic: The magic delivers something traditionally spread by contact, like infection or flames. Still, a built-in ability not to kill the wizard is advisable.

Enchantment spells (pp. 13-14) can do almost anything. For an item to be artillery in its own right rather than an artifact that casts artillery spells, visualize it not as a cannon but as a bomb: a single-use item that expends its magical might in an explosion or other mass destruction.

Special spells are too weird to classify. None appear here, but if a spell causes mass harm without an area or individual as its subject, with no attack roll, and no item as its intermediary, it’s Special. GURPS Magic tends to class Regular spells that affect only the caster as Special. Do this if you prefer – but the discussion under Regular (pp. 4-5) remains applicable.

Blocking and Information spells aren’t suitable as artillery. It’s tempting to imagine Blocking spells that deliver mass-damage effects on the defensive, but enabling magic-wielders to wound multiple foes by reflex – without so much as using up a maneuver – isn’t balanced. And Information spells might gather knowledge that can do harm in the strategic or social sense, but physical injury makes little sense.

原書表記

A Congregation of Colleges

Almost anything could prove harmful at sufficiently excessive power levels, so spells that lay waste to areas or injure multiple foes suit most colleges – though not all. College influences not only prerequisites but also how the magic does damage (often suggesting interesting side effects). Below are some ideas. To state the obvious: Everything here is meant to affect more than one victim!

Air: Concussive shock; crushing pressure; poison gas; suffocating vacuum; tearing winds.

Animal: As general artillery, conjured swarms. More specialized are devastating Body Control-like effects that affect animals only.

Body Control: Deathtouch-style direct injury, mainly – but special effects can vary.

Communication and Empathy: Telepathic mind blasts.

Earth: Collapsing architecture; falling or flying rocks; stinging sands; unnatural disasters such as conjured avalanches, earthquakes, and volcanoes.

Enchantment: One-shot objects that do wide-ranging damage when activated – almost anything is possible!

Fire: Blazing ground, burning explosions, incendiary clouds, pillars of flame, and other fiery spectacles; lava and volcanoes (again); scorching heat without open flame.

Food: Not especially suitable, although a “mass” version of Poison Food could be loosely interpreted as artillery against an army.

Gate: Folding space or warping time in harmful ways; portals that admit destructive forces or the attacks of destructive beings from other dimensions.

Healing: Bona fide healing is unsuitable, but don’t forget this college includes spells for sterilizing and surgery – effects that would be harmful if applied to a mass of people without regard for their condition.

Illusion and Creation: Dangerous creations or phantoms numerous or widespread enough to menace many people at once. (True illusions lack the necessary teeth.)

Knowledge: Simply not appropriate for artillery, but its spells might be prerequisites for spells of other colleges, justifying intricate magical “targeting systems.”

Light and Darkness: Focused sunlight; searing fantasy “lasers”; even bright ordinary light, for creatures of darkness. Dangerous shadow is the realm of Necromantic spells.

Making and Breaking: Weaken, Shatter, Rive, Explode, and Disintegrate variants that cause destruction in ways that endanger anyone nearby – or that cut out the middleman and cause explosions directly.

Meta-Spells: Twisting mana in ways that endanger wizards, supernatural beings, or all beings.

Mind Control: Making multiple subjects behave dangerously, whether through direct control or by manipulating perceptions. Damaging attacks on the mind fall into the realm of Communication and Empathy.

Movement: Collisions and falls; flying objects; flying subjects; telekinetic blows; teleporting bad things onto people or people onto bad things.

Necromantic: Conjuring minor demons, shadows, or zombie hands (which burst out of the ground) to attack everyone in an area. Directly blighting people falls under Body Control. Blasting all undead or spirits in an area fits, however.

Plant: Falling nuts or boughs; flying splinters; stinging leaves; thorns; toxic pollen; whipping branches. Any harmful effect that affects plants only.

Protection and Warning: Force Dome and Force Wall – being ultimate as they are – lead to excellent force balls, force blades, force fists, etc.

Sound: Harmful vibrations; resonant attacks; shockwaves; sounds loud enough to do actual damage.

Technological: Energy spells that turn energy, especially fuel, into artillery; Radiation spells that irradiate or shoot death rays. Machine spells that destroy technology only also qualify.

Water: Acid; dehydration; devastating cold; drowning; jagged ice; steam.

Weather: Destructive winds; freezing; hail and ice storms; lightning in all its forms (bolts, balls, and strange phenomena not found in nature).

「[[砲兵系呪文の規則>GURPS Magic: Artillery Spells#By]]」

原書表記

By the Numbers
The artillery spells in GURPS Magic don’t hint at a design system, and imposing one after the fact would lead to “rules” that consist mainly of exceptions and special cases! What follows are guidelines for GMs who want to assign more-or-less balanced statistics to homemade spells. These notes aren’t intended for Enchantment spells, which don’t have casting times, energy costs, etc. in the ordinary sense; for advice on those, see Enchantment Spells (pp. 13-14).

「[[L-威力>GURPS Magic: Artillery Spells#Damage]]」

原書表記

Damage

One-shot damage typically involves either a fixed roll somewhere between 2d and 5d, or a range that depends on energy spent, running from 1d to between 3d and 5d. A fixed 2d or 3d, or an adjustable effect ranging from 1d to 3d, suits spells that largely or entirely bypass DR: direct HP loss, area-effect contact poison, electricity that treats metal armor as DR 1, etc. Save 4d and 5d for magic DR can mitigate to a meaningful extent. If a spell offers variable dice in a campaign that uses Magery and Effect (GURPS Magic, p. 9), remember that maximum Magery level sets the real upper limit.

Missile spells are an important exception. They should be capable of the standard 1d per Magery level per turn, for three turns – in effect, maximum damage is 3d \ Magery.

The other major exception is spells that inflict damage over time. Generally, damage should be low: 1 to 2 points per turn if the effect bypasses DR in some way – or as much as 1d per turn if there’s a penalized attribute roll, standard resistance roll vs. the spell, or similar “saving throw” each turn. Damage should be higher only if the roll to avoid it is something ordinary warriors would often succeed at, like a straight DX roll or an active defense roll with the benefits of Defense Bonus and retreating.

Within reason, damage dice can have adds. Look at existing examples to assess this. For instance, Stone Missile is at +1 per die because crushing damage is the least deadly type; Fire spells mostly get 1d per level of effect; and Acid Jet has ‑1 per die because it dissolves DR and causes blindness. Crushing, burning, and corrosion might work this way in general.
Damage with many special benefits may also have ‑1 per die; lightning-related magic is like this because it sets fires as capably as other burning damage and short-circuits metallic DR, stuns, and surges electronics.

Damage type follows from the college and the spell’s special effects: toxic for nasty bugs and plants, and noxious gas; crushing for explosions and impacts; burning for fire, lightning, and intense light; cutting for blades (including blades of force); impaling for pointy things; corrosion for acid. Direct injury – such as the ever-popular “life-draining touch” – requires no damage type, but if it’s actually damage that ignores DR, assign one.

Artillery spells often have effects beyond damage; e.g., brilliant light blinds, while concussion deafens or stuns. These demand creativity and flexibility. Make lists of real upsides and downsides (not just minor special effects). For example, extreme cold might not set fires despite being “burning,” concussion may deafen but also be useless except in air, and poison could cause sickness but also affect only the living. If one list is longer than the other, consider either applying ‑1 or +1 per damage die to balance matters, or leaving damage alone and adding something to the shorter list. See Modifiers (pp. B101-117), especially Side Effect and Symptoms (p. B109), for inspiration; for instance, cold might paralyze.

「[[L-持続時間>GURPS Magic: Artillery Spells#Duration]]」

原書表記

Duration

A lot of artillery – notably cones, explosions, and higherdamage Area spells – does damage once per casting. Duration is instantaneous in this case, or at most one second if the spell needs that long to do harm because it inflicts damage on each victim’s next turn or on the caster’s following turn.
Missile spells endure for a single attack but can be “held” indefinitely before use.

Other artillery does damage over time. This almost always implies an Area spell, or a Regular spell that produces an area effect around its subject. Recommended duration is five to 10 seconds, with the shorter end being more balanced if damage is more than a couple of points and difficult to avoid. For anything longer (even a minute is a long time when you’re being injured!), damage should be easily prevented through a “saving throw,” an active defense, or modest DR – or else energy cost ought to be exceptionally high.

All this refers to the spell’s duration. Injury lasts until healed. Damage effects may endure for turns (stunning), minutes (common for deafness), or even longer (dissolved DR, crippling, etc.) – or “until dealt with” (like ordinary fires set by burning damage).

「[[L-エネルギー消費>GURPS Magic: Artillery Spells#Energy]]」

原書表記

Energy Cost

Most artillery spells are Area spells. For these, a base cost of two energy points per 1d of damage is recommended. If the number of dice is fixed (e.g., a flat 3d), adjust final base cost upward or downward slightly to reflect additional effects especially favorable or unfavorable to the caster. If the number of dice is variable, it’s better to leave cost alone and adjust damage adds.

For Regular spells that produce cones or area effects, or otherwise cover multiple hexes on a battle map, set energy cost competitively based on the number of hexes they’re likely to affect. Remember that cones rarely menace everyone in their area – closer figures screen more distant ones.

The above assumes a one-shot effect. For damage over time, estimate total damage assuming likely exposure; a minute-long spell isn’t superior to a five- to 10-second spell unless it glues people in place for the duration, and damage may be capped for any spell (e.g., Ironweed, pp. 25-26, doesn’t matter after the victim’s feet are crippled). Halve this if victims can easily avoid the assumed damage by leaving, making a “saving throw” each turn even if they stay, etc. Throughout, treat every 3.5 points as 1d.

Then use the pricing guidelines for one-shot spells. Round down for spells with few positive damage effects, or up for exceptionally capable ones or those that bypass DR. For instance, if a spell does 1 HP/second that’s avoidable by running away, and endures for 10 seconds, it’s priced as 1 HP/second \ 10 seconds \ 1/2 (avoidable) = 5 points, or 5/3.5 = 1.4d, so a base cost of 2 \ 1.4 = 2.8 energy would be fair, rounded to two points in most cases, to three if DR is ineffective.

For any Area spell, a useful trick to keep casters honest – and to make artillery behave like artillery – is to set a minimum radius of two yards. This makes the spell’s minimum cost double its base cost, curbing overuse and making wizards think twice before casting close to allies, as they can’t manage pinpoint accuracy. Imposing this caveat consistently means Area artillery without it (note this!) stands out as special; magic-users might learn such spells for that reason alone.

Missile spells capable of damaging multiple targets by exploding, affecting everyone along a line, ricocheting between enemies, or anything similar start at two energy points per die. If clearly superior to existing explosive Missile spells, bump cost to three energy per die. The most common example is an explosion with damage divided by distance in yards from the center of the blast rather than triple that.

Price a Melee or Special spell by comparison to the class above it most behaves like. However, if a Melee spell does just X dice of damage in total – all targets considered – then one energy point per die (like Deathtouch) is fair.

コラム：「[[L-維持はどうなの？>GURPS Magic: Artillery Spells#Maintenance]]」

原書表記

Maintenance?
Maintainability for damage-over-time magic is a question of style more than game balance – but if a spell requires more than three seconds to cast, consider making it maintainable. Energy cost to maintain for a period equal to the spell’s duration should be the same as cost to cast unless its effects grow less effective because victims can easily adapt to avoid, defend against, or neutralize them. In that case, use half cost.

「[[L-準備時間>GURPS Magic: Artillery Spells#Time]]」

原書表記

Time to Cast

GURPS Magic balances spell effectiveness using energy cost and to a lesser extent prerequisite count. Casting time plays only a small role; e.g., “Seek” spells are easy to learn and not overly powerful, yet the majority require 10 seconds to cast, while many deadly combat spells take but one second. In fact, time often comes down to a matter of “feel”: Why does Charm take three seconds to Control Person’s 10 seconds, when both last a minute, cost six energy, and let a wizard march people to their death, yet the latter is less capable (caster’s body falls limp, subject’s skills are inaccessible)? Because Mind Control spells are optimized for combat, while Communication and Empathy magic is meant for “social” situations.

Consequently, it’s most consistent to use the closest spells of the same college as guidelines – especially when they’re essentially less-destructive versions of the artillery spell, named as its prerequisites (e.g., as Stench is for Cloud of Doom, p. 9). If rapid recasting of a one-shot area-damage spell seems excessive, one second per yard of radius (for fixed-damage spells), per die of damage (for variable-damage spells, especially those that range up past 3d), or per X energy points of base cost (X = 2 is consistent with the energy cost per die suggested for artillery) all have precedents and are fairly balanced.

Missile spells take their usual one to three seconds to cast, regardless of how they work.

「[[L-前提条件>GURPS Magic: Artillery Spells#Prerequisites]]」

原書表記

Prerequisites

To keep artillery spells the province of archmages, assume that most require Magery 4 or more (maybe even Magery 5 or 6!) and at least 10 other spells.

The Magery prerequisite is negotiable. In settings where Magery 3 is the maximum, there’s no harm in stopping there. If none of the specific prerequisite spells require high Magery, it’s possible to go with Magery 2 or even Magery 1, though it’s easier to justify making artillery spells rare (if desired) when their Magery requirements are at least one level higher than the highest among their prerequisite spells. The GM who favors modest Magery levels is welcome to tone these down for the spells in Chapter 2, while one who likes lots of Magery – the GURPS Dungeon Fantasy approach – might lean in the other direction.

The exact spell prerequisites aren’t important, as any 10 spells cost the same number of character points; indeed, the sweeping “one spell from each of 10 different colleges” has many high-powered precedents in GURPS Magic. Still, it’s flavorful to assume that a college’s artillery is among its most advanced magic, to mandate that its prerequisites come largely or wholly from within the college, and to specify a few that are similar in “feel” to or even lesser versions of the same magic. For instance, Improved Explosive Fireball (p. 15) requires not just any 10 spells, but 10 Fire spells – Explosive Fireball among them.

If it’s impossible to learn the artillery spell’s prerequisites without going outside its college, the number of prerequisite spells within the college may be smaller to compensate. This doesn’t have to be the case, though – if artillery is meant to be hard to learn, a few extra prerequisites simply underline this. Think of 10 spells as a minimum, not a fixed target.

「[[L-微調整>GURPS Magic: Artillery Spells#Tweaks]]」

原書表記

Tweaks

There are endless variables in spell design! A spell may be less effective than it looks, commonly because it affects only some targets: living creatures, animate beings, magical entities, etc. Its scope might be even narrower, like animals, machines, plants, or undead. The magic’s effects could be easy to avoid; e.g., enemies worth blasting with artillery are typically combatants, implying respectable ST, DX, and HT – and fair active defenses – so “saving throws” against these unmodified scores won’t be challenging. Or perhaps the effect is highly conditional; for example, Flammability (p. 26) doesn’t do anything until somebody is set alight.

Other spells are more effective than is obvious at first. They might travel beyond their initial boundaries, inflict long-duration side effects or symptoms, or bypass defenses and DR that should be effective against that kind of thing. They may just do lots of damage.

It’s entirely reasonable to increase duration, lower energy cost, reduce casting time, and/or call for lesser prerequisites if a spell is relatively anemic – or to do the opposite if the magic is especially potent. A spell with somewhat lackluster foe-smashing potential might still be worthwhile if it’s long-lasting, cheap, and quick, while genuine magic of mass destruction merits being expensive in every way.

It’s always possible to adjust damage – but be careful! Even if a spell seems too easy to learn and cast, it isn’t always wise to lower damage to compensate, because if damage gets too low – and especially if it’s affected by DR – it won’t threaten “cannon fodder” as intended. Consider leaving damage alone and making the spell more demanding in other respects. Similarly, if the spell feels onerous to learn and cast, raising damage isn’t necessarily the fix, as that can create an undesirable “boss killer.” Think about leaving damage modest and softening the spell’s requirements to make routine use against fodder more attractive.

「[[魔法の素質と……>GURPS Magic: Artillery Spells#Magery]]」

原書表記

Magery and . . .
Several spells become more effective artillery if the GM applies Magery and Effect (GURPS Magic, p. 9). Exactly how this rule works isn’t always obvious, so suggestions appear for each college with relevant spells. Like the rule, this advice is optional – the GM may ignore it or apply it only in certain cases. When using it, it’s fairest if it holds for magic enabled by all spellcasting advantages; e.g., high Power Investiture increases maximum effect for clerics, just as high Magery does for mages.

Cloud of Doom (VH)
Area
Produces a greenish cloud of contact poison. Anyone in the area must roll vs. HT‑4 every second to avoid 1d toxic injury; DR has no effect. After losing 1/2 of their HP this way, victims are nauseated (see Afflictions, p. B428) until the injury is healed above that threshold.

Cloud of Doom cannot injure those with Immunity to Poison or Sealed. Resistant to Poison grants its bonus to the HT rolls. Doesn’t Breathe and Filter Lungs (and holding one’s breath) are ineffective – the gas needn’t be inhaled to be harmful!

The cloud is hazy but not especially dense: Vision and ranged attack rolls through it have a flat ‑1 (not per yard). The gas doesn’t persist for long enough for displacement or dissipation by wind to become an issue.

Duration: 5 seconds.
Base cost: 5. Minimum radius two yards. Cannot be maintained.

原書表記

Falling Sky (VH)
Area

Instantaneously raises air pressure to extreme levels, crushing everything within the area. This damages anything an ordinary explosion would affect (thus, Pressure Support has no effect), and counts as large-area injury (p. B400). Anyone this spell injures must also roll vs. HT.

Modifiers: ‑1 per full five points of injury; +1 for ordinary earplugs, or +5 for Protected Hearing.

Failure inflicts a Hearing penalty equal to margin of failure; failure by 10+, or critical failure, causes deafness. Either effect lasts (20 ‑ HT) minutes, minimum one minute. After that, roll vs. HT each turn to recover. Critical failure on a recovery roll indicates a permanent injury (Duration of Crippling Injuries, p. B422): Hard of Hearing if the penalty was ‑1 to ‑9, Deafness if deafness occurred. Protected Hearing cuts duration to two seconds and makes recovery automatic. Any failure on the initial HT roll also stuns the victim; roll vs. HT each turn to recover.

Unlike an explosion, there’s no damage drop-off with distance from the center and no special effect in enclosed spaces. Effects are uniform within the area and end abruptly at its edges.

This spell is ineffective in vacuum, underwater, in solid earth, etc. – there must be a gaseous atmosphere of some kind.

Duration: The spell lasts an instant, but deafness and stun persist as noted above, and injury remains until healed.
Base cost: 2 to 10; the blast inflicts 1d crushing damage per two energy points put into the base cost. Minimum radius two yards.
Time to cast: 1 second per two energy points of base cost.
Prerequisites: Magery 4 and at least eight Air spells, including Concussion and Destroy Air.

Twisting Terror (VH)
Regular
Conjures a small tornado that rips across the ground, smashing everything in its way. The caster must choose a starting point (calculate distance penalties from that point).
The twister appears there and cuts a swath one yard wide, traveling one yard per two energy points in the spell and then dissipating. The caster does not control the path – each yard, roll for Scatter (p. B414) to determine the direction moved.

Anyone the tornado would touch may attempt to dive for cover (p. B377) to get out of its path. Other active defenses are ineffective. Success means that person ends up on the ground, unharmed. The tornado can sweep over a victim repeatedly,
doing damage with each pass. If that happens, diving for cover is useful just once.

Those who fail to get out of the way are pummeled with a 2d crushing attack; this is large-area injury (p. B400). Use double damage to calculate the amount of knockback, and Scatter to determine its direction.

Needless to say, this spell is best cast at a safe distance from the caster and any allies!

Duration: The tornado lasts for long enough to take one turn immediately after the caster’s, like a swift fighter tearing around the battlefield. Injury remains until healed.
Cost: Any even-numbered amount! The tornado travels one yard per two energy points spent.
Prerequisites: Magery 4 and at least 10 Air spells, including Windstorm.

「[[コラム：賭け金を上げる>GURPS Magic: Artillery Spells#Upping]]」

原書表記

Upping the Ante

When starting a new campaign, GURPS Magic: Artillery Spells adds a t iny pinch of spells to the 800+ in GURPS Magic and hundreds more in the GURPS and Pyramid libraries. Vetting them adds little to the GM’s workload. If something seems overpowered, adjust it (GURPS Thaumatology o ffers s olid a dvice), u se GURPS Thaumatology: Magical Styles to restrict it to specific schools, or put an Unusual Background cost on it. Review The Receiving End (p. 5) to make sure such magic doesn’t make it too easy to defeat key opponents,
like “boss” monsters.

Rolling out artillery in an ongoing campaign is a bigger challenge. The above vetting process remains necessary – but now it’s after the fact, and the GM must be careful not to leave players feeling cheated, especially if they’re familiar with high-powered fantasy and feel limited by Magic. Some advice: Keep your head down! There are no specific defenses against artillery spells, but the heroes shouldn’t be caught flat-footed if their first exposure is as targets! Apply The Receiving End fairly. Even if the PCs have never seen such magic, it doesn’t take genius-level IQ to dive for cover or cast an Armor spell.

Military grade. Artillery magic might be the preserve of nations – not secret, just unshared. In our world, howitzers, missiles, and stealth bombers are known to exist but are LC1 or even LC0, unrestricted only in societies in or near anarchy (CR0 or CR1), and costly regardless. Most fantasy societies are tribal, dictatorial, or theocratic, with CR3-6 – and the feudal kind tend toward the high end.
These might view Missile spells much as our world sees LC3-4 hunting and self-defense weapons, and exploding ones like LC2-3 explosives, yet restrict artillery magic. Access may require the PCs to earn Legal Enforcement Powers, Rank, Security Clearance, or Status, or to be deputized or given a valid military mission, in play – any of which might require a long career of “proving” themselves first.

Nobody uses artillery where bullets would do. Perhaps artillery spells weren’t needed until the moment of introduction. In a campaign with a detailed setting and story arc, the numberless legions of a supernatural overlord, the outbreak of a zombie plague, or the opening of the gates of Hell might spur wizards to invent new “technology” useful for battling hordes many times larger than classic low-tech fantasy armies. In a character-centered game, the PCs may precipitate this reaction! Perhaps they’ve grown so powerful that their foes are willing to unveil secret, greatly draining magic – or that quest-givers believe hurling the heroes against such enemies is a worthwhile gamble.

Arms dealing. The idea that no authorities are corrupt and all secrets are kept flawlessly strains willing suspension of disbelief. For the right high price – or in return for a service – there’s surely somebody who will teach artillery magic. The PCs might find grimoires as spoils. If they’re attacked by such a spell and try to research it, they should get a bonus: at least +2, but up to +5 for supercharged variants of common spells. The introduction of artillery magic makes a fine quest!

Creeping Plague (VH)
Area
Conjures a carpet of crawling, venomous vermin: bullet ants, centipedes, scorpions, spiders, and almost any other creeping invertebrate that stings or bites. Water offers no refuge – it’s teeming with jellyfish, leeches, stinging echinoderms, and other horrors. Everyone on the ground or swimming in the area is engulfed and attacked. No active defense roll is allowed.

Clothing (DR 0 garments) protects completely against the pests for two turns; armor (DR 1+) protects for five.
After that, DR becomes irrelevant and the victim suffers 1d-1 toxic injury per turn in the area, halved (round down) on a successful HT roll. Resistant to Poison aids this HT roll, while Immunity to Poison or Sealed prevents harm.

Unlike a mundane swarm, this one doesn’t move on its own.
By taking a Concentrate maneuver, however, the caster can shift the area along the ground at Move 2 (though not change its shape) to chase victims or torment new ones.

Also unlike a mundane swarm, this one is unaffected by damage. For the spell’s duration, new creepy-crawlers appear within the area to replace slain ones. People who leave the area bring vermin with them; these can be killed. Fleeing victims continue to count as exposed until the spell ends or they inflict 15 HP of injury on their passengers; see Attacking a Swarm (p. B461). Reentering or being overtaken by the area means starting all over again!

Example: An armored orc is caught within a Creeping Plague. He flees immediately, so he’s only in the swarm for one turn. He begins swatting (2 HP/turn) and stomping (1 HP/turn) at the pests on him; after four turns, he’s inflicted 12 HP. While he’s flapping and hopping, the caster moves the spell back onto him, so on his sixth turn, not only is he exposed for long enough that he starts to take injury (armor protects for five turns), but his efforts count for naught. If he flees again, he’ll need five more turns to deal 15 HP, during which time he’ll suffer toxic injury every second.

Duration: 1 minute.
Base cost: 2. Same cost to maintain. Minimum radius two yards.
Time to cast: 2 seconds.
Prerequisites: Magery 5, Beast-Summoning, and Vermin Control – or Magery 4 and Create Animal.

Plague Touch (VH)
Melee
This insidious Deathtouch variant affects multiple subjects in succession. When cast, its energy cost is spent immediately but held in a “reserve.” Keep track of this, marking off three energy points each time the spell inflicts injury. When the reserve is empty, the spell ends.

The initial victim touched suffers what appears to be a standard 3d Deathtouch, but also becomes a “carrier.” Anybody that person touches without deliberate hostile intent suffers 3d Deathtouch and becomes a carrier, too. This goes on until the spell exhausts its reserve. While energy remains, all carriers remain carriers – one subject could affect any number of others. Only the living or undead take injury, but anyone can be a carrier! However, nobody can be zapped more than once by a given casting of Plague Touch.

For this spell’s purposes, a “touch” includes a deliberate touch (e.g., to render first aid or cast a helpful spell), an accidental bump (as from knockback), or even handing off an object. A person simply passing through a non-hostile hex must roll vs. DX, with failure indicating a brief touch. It’s unimportant which party initiates contact. Opponents in battle are assumed hostile; the magic won’t spread to them under any circumstances.

Counterspell and Dispel Magic can negate Plague Touch, but only for carriers they’re cast on. Plague Touch resists separately for each victim. If any trace of the spell remains, it can continue to wreak havoc.
This spell is most useful against low-IQ foes who attack in tightly packed hordes, like zombies. However, creative users can exploit it in other ways; e.g., by corralling enemies into contact and then casting it.

This is also a Necromantic spell.

Duration: Until the spell’s reserve is empty. Does not count as a spell “on.”
Cost: Any multiple of 3 – minimum 6, no maximum. Cannot be maintained.
Time to cast: 2 seconds.
Prerequisites: Magery 4, Deathtouch, Pestilence, and Sense Foes.

Psychic Scream (VH)
Regular

Causes the caster – who must also be the subject – to emanate an invisible psionic pulse that injures any nearby being that possesses a mind. Despite threatening an area that depends on the energy spent, this is not an Area spell. The effect is on and moves with the caster.

For as long as the spell endures, all beings with minds – friend or foe, everybody but the caster – suffer 1 HP of toxic injury per second while in the area. This injury bypasses all DR save for that specifically effective against psionic attacks. As the pulse is psionic rather than magical (only the caster is affected by magic), it ignores Magic Resistance, is unaffected by countermagic such as Spell Shield, and can penetrate no-mana areas.

In campaigns that use GURPS Psionic Powers, abilities based on Psi Static block this spell, while those that give DR against psionics (notably Psychic Armor) work normally.
GURPS Psi-Tech gadgets that provide similar effects are likewise effective. Where such things work using a resistance roll, use the caster’s effective skill vs. that of the psionic ability or device.

Duration: 10 seconds.
Cost: 3 per yard of radius. Same cost to maintain. Minimum radius two yards. Figure full cost before applying reductions for high skill, as for an Area spell.
Time to cast: 1 second per yard of radius.
Prerequisites: Magery 4 and at least 10 Communication and Empathy spells, including Mind-Sending.

Boulder Barrage (VH)
Area

Conjures a lot of Stone Missiles (GURPS Magic, p. 52) over the area and sends them down in a dense hail. Everyone (and everything, if material destruction matters) is attacked once at effective skill 12, adjusted only for target Size Modifier.
Success means one hit plus one more per two full points of success; e.g., for an SM 0 target, one hit on 11-12, two hits on 9-10, three on 7-8, and so on.

Victims may block or dodge, at ‑2 for an attack from above (p. B402), but not parry; shield DB adds normally. Success avoids one hit plus additional hits equal to margin of success.
Determine hit location randomly. Overhead cover provides its usual benefits; Dodge and Drop (p. B377) is only effective if there’s cover to dive for!

Boulder Barrage is much like a higher-damage, one-off variation on Rain of Stones. Unlike that spell, however, it works anywhere, even indoors. Another difference is that a shield provides only a chance to block – not total protection.

Duration: The spell lasts an instant, but injury remains until healed.
Base cost: 2 to 6; each missile inflicts 1d+1 crushing damage per two energy points put into the base cost. Minimum radius two yards.
Time to cast: 1 second per two energy points of base cost.

Sand Blast (VH)
Regular

Shoots a 10-yard-long cone of high-speed grit from one hand, inflicting large-area injury (p. B400). Maximum width increases with the energy put into the spell, but this isn’t an Area spell.

Use the rules under Cone Attacks (p. B413), rolling vs. Innate Attack (Beam) to hit the target point. As for any cone, anybody completely screened from the caster is behind cover, and targets may use Dodge and Drop (p. B377) to leave the area or get to cover.

Beings with eyes must roll vs. HT if this spell inflicts any injury. Failure means being blinded for one turn; critical failure causes 1d seconds of blindness. Once the target can see again, blurry vision gives ‑3 to all combat skills and Vision rolls for a further 1d seconds.

Duration: The spell lasts an instant, but blindness and Vision penalties persist as noted above, and injury remains until healed.
Cost: 2 to 6, for 1d crushing damage per two energy points, multiplied by terminal width in yards (minimum one yard, maximum five); e.g., 16 for a four-yard-wide cone that inflicts 2d crushing. Figure full cost before applying reductions for high skill, as for an Area spell.

Seismic Shock (VH)
Area

Triggers a massive, momentary shock that lifts anyone on the ground five yards into the air. On landing, they suffer falling damage from that height. Typically, the ground or floor counts as a hard object, meaning 2d crushing for people with HP 8-12, increasing by +1d per full +5 HP (3d at HP 13-17, 4d at HP 18-22, . . .). For details, see Collisions and Falls (pp. B430-431).

If the ceiling is lower than five yards, damage is instead as for two falls: one from an effective (5 ‑ ceiling height) yards for smashing into the hard ceiling, and another from ceiling height for crashing to the floor afterward.

A successful Acrobatics roll reduces effective falling distance by five yards. Thus, it’s possible to avoid all damage from hitting the ground. This doesn’t mitigate damage from being slammed into the ceiling first, however!

In all cases, Hit Location from a Fall (p. B431) applies. Injury is not large-area, but all armor counts as “flexible” against this damage.

Landing location is random. On a combat map, pick up each affected figure and drop it from 5” up (about the height of a soda can). Upon landing, victims capable of standing may make a DX or Acrobatics roll at ‑3 to land on their feet.

Example: A victim with HP 15 is standing in a two-yardhigh tunnel; smashing into the ceiling is equivalent to a fall of 5 ‑ 2 = 3 yards, which corresponds to velocity 8. First they slam into the ceiling, for (15 \ 2 \ 8)/100 = 2.4d damage, rounded to 2d; damage is 7 to the leg. Then they drop two yards to the floor with velocity 7, for (15 \ 2 \ 7)/100 = 2.1d; rolling 2d, damage is 8 to the torso. With DR 2 armor, injury is 5 HP to the leg and 6 HP to the torso. Those wounds aren’t enough to cripple a leg or cause knockdown or unconsciousness, so a DX-3 roll is possible to land standing. Outdoors, arcing up five yards and landing with velocity 10 would inflict (15 \ 2 \ 10)/100 = 3d damage; if that happened to a leg, a middling damage roll of 10 would inflict 8 HP after DR 2, crippling the leg and ensuring the victim ends up lying down.

Seismic Shock also causes general chaos. Objects that require checks for breakage if dropped (like potion bottles) must roll for breakage, people taking Aim or Concentrate maneuvers must make Will rolls for distraction, those engaged in long actions must roll vs. the relevant skill or start over, and machinery requires a HT roll to avoid breakdown (e.g., locks on portals would pop open). For targets not securely anchored to the ground – and people rarely are – these rolls are at an extra ‑3.

This spell has no effect on targets not in contact with the ground.

Duration: The spell lasts an instant, but tactical confusion lasts as long as it takes to resolve and injury remains until healed.
Base cost: 8. Minimum radius two yards.
Prerequisites: Magery 4 and at least 10 Earth spells, including Earthquake.

「[[L-魔化系呪文>GURPS Magic: Artillery Spells#Enchantment]]」

原書表記

Magic items bearing spells in this collection should be rare, if they exist at all. This is a matter of game balance: If Ye Olde Magick Shoppe sold artillery as a matter of course, it would be unfair to wizards who’ve completed quests, invested character points, and/or spent money to obtain such spells, the high Magery levels they require, and sufficient energy to exploit them. It’s fairest to treat such gewgaws as extraordinary artifacts.

If the GM wants to allow enchantment, however, a fair energy cost is twice that of the item for the most expensive named prerequisite spell. For instance, Death Field calls for 10 Body Control spells but names only Deathtouch (2,500 energy), while Plague Touch specifies Deathtouch, Pestilence (1,000 energy), and Sense Foes (200 energy), implying 5,000 energy in either case. The GM may prefer a single high cost (e.g., 4,000 or 5,000 energy) in all cases – or whenever these guidelines fall short, especially when no spells are named – to reflect the rare skill set required and probable monopoly on sales among the enchanters involved. All such items work only for mages, enabling them to cast the spell normally.

On the other hand, some items might be artillery in their own right . . .

Doom Wish (VH)
Enchantment
This Great Wish variant can do but one thing: wreak widespread destruction. Instead of making 1,000 energy available to cast one spell automatically, the full 2,000 energy is available – but only to do harm. Each energy point inflicts 1 HP of injury, and the wish-maker can divide this among any number of people or objects in line of sight. The effect cannot be resisted, and DR is of no benefit.

The wish-maker must specify the effective damage type, which has to be the same for all targets. This counts only for the purpose of exploiting disadvantages and limitations; it causes no special damage effects (e.g., “burning” doesn’t set fires). The injury is also considered magical, where relevant.

Example: Marge the Barbarian is surrounded by 20 trolls that have HP 20, Unkillable 3 with Achilles’ Heel vs. burning and corrosion damage, and Regeneration ineffective against the same. Bad odds, even for a barbarian, so she decides to use her tribe’s prized Doom Wish item on them. Not knowing the trolls’ exact HP, she inflicts equal injury on them all: 100 HP apiece. Knowing trolls as she does, she specifies burning injury. All 20 trolls drop to ‑4\HP and need four HT rolls to avoid death. Any reaching ‑5\HP due to prior wounds die automatically – and any survivors can’t regenerate the lost HP.

This is not a death spell in the GURPS Magic: Death Spells sense, but a big dose of injury. While DR is ineffective, other traits can prevent death if the user chooses badly; e.g., if Marge picked crushing injury, the trolls’ Unkillable would keep them alive and they’d regenerate. Foes with Injury Tolerance (Damage Reduction) (GURPS Powers, pp. 53, 118-119) may require two or more times the “obvious” amount of injury to slay. Against one victim, this spell is nearly always fatal. Then again, a standard Great Wish could kill almost anybody with an irresistible 1,000-energy casting!

As with Great Wish, this spell can never be learned at a level better than 15, and any failure when casting it costs the caster and each helper a level of IQ and 6d injury. On a critical failure, injury is 6d or 2,000 HP divided by the number of ritualists, whichever is worse (on average the latter, unless there more than 95 participants).

Energy cost to create: 2,000.
Prerequisites: Magery 3, Wish, and a total IQ + Magery of 23+.

原書表記

Vengeful Staff (VH)
Enchantment

Imbues a handheld item – traditionally but not necessarily a staff – with the one-time ability to explode when broken. Accidental breakage never sets off the blast, although it does end the enchantment. The trigger is much more specific!

To blow up the item, the wielder must grasp it with one or more hands (not remotely, as via a Movement spell or Telekinesis), declare the intention to activate it, and take one second – a maneuver in combat – to destroy it. Dashing it against something hard and immovable counts as an attack, deals the object maximum swing damage for the user’s ST, and can benefit from All-Out Attack (Strong). Snapping it is considered a Ready maneuver, involves winning a Quick Contest of (ST ‑ artifact’s DR) vs. (artifact’s HP), and can involve extra effort. A spell such as Shatter must be cast by touch using the usual Concentrate maneuver(s).

Alternatively, if the item is broken by enemy action while in the owner’s hands – e.g., by an attack powerful enough to shatter it when used to parry (Parrying Heavy Weapons, p. B376), or by a hostile artillery spell – the wielder can attempt to initiate the blast with a simple Will roll.

However the blast is triggered, it’s a crushing explosion that does 6d \ square root of (object weight in lbs. \ 4) damage.
For instance, a 1-lb. baton (“wand”) does 6d\2 cr ex, while a 4-lb. quarterstaff detonates for 6d\4 cr ex. The holder always suffers this damage – there’s no workaround – while everyone else divides damage by distance in yards from the holder (not triple that). Average damage from an exploding quarterstaff (84 points) could easily kill everyone within four yards (84/4 = 21 points).

Energy cost to create: 20 times dice of damage (e.g., 240 energy for a baton or 480 energy for a staff). This is half the price of a Spell Stone for Concussion with equivalent damage dice because while the blast tapers off slowly, it calls for specialized conditions and will blow up the user!
Prerequisites: Magery 3, Enchant, and Explode.

原書表記

Fire Swarm (VH)
Regular
Unleashes a conical swarm of (non-explosive) fireballs from one hand. These streak out to 10 yards and then dissipate harmlessly. Maximum cone width increases with the energy put into the spell, but this isn’t an Area spell.

Use the rules under Cone Attacks (p. B413) to position the swarm, rolling vs. Innate Attack (Beam) to strike the target point. This doesn’t guarantee hitting everyone and everything, though.
Roll once per target in the cone at effective skill 12, adjusted only for target Size Modifier. Success means one hit plus one more per two full points of success; e.g., for an SM 0 target, a roll of 9 or 10 gives two hits.
As with any cone, anybody completely screened from the caster is behind cover, and targets may use Dodge and Drop (p. B377) to leave the area or get to cover. Those who cannot or choose not to use this option may block or dodge individual fireballs, but not parry them; success avoids one fireball plus additional hits equal to margin of success.
Determine hit location randomly for each hit.

Duration: The spell lasts an instant, but injury remains until healed.
Cost: 2 to 6, for 1d burning damage per fireball per two energy points, multiplied by the terminal width in yards (minimum one yard, maximum five); e.g., 30 for a five-yard-wide swarm that inflicts 3d burning per fireball. Figure full cost before applying reductions for high skill, as for an Area spell.
Time to cast: 1 second per die of damage.
Prerequisites: Magery 4 and at least 10 Fire spells, including Fireball and Flame Jet.

Similar to Explosive Fireball (GURPS Magic, p. 75), but with a bigger blast radius: targets a yard or more from the center divide damage by distance in yards instead of by three times that.
For the caster’s safety, range is also greater: Acc 2, 1/2D 50, Max 100.

Towering Inferno (VH)
Area

Calls down a vertical column of flame that scorches everything within it. This inflicts large-area injury (p. B400).
It’s an area effect, not an explosion – damage applies equally throughout the area, yet things beyond the edges aren’t even singed. Especially at higher levels, though, this spell is likely to start fires (see Making Things Burn, p. B433); these spread normally.

Duration: The spell lasts an instant, but injury remains until healed and any fires set burn until extinguished.
Base cost: 2 to 10; the flames inflict 1d burning damage per two energy points put into the base cost. Minimum radius two yards.
Time to cast: 1 second per two energy points of base cost.

Area
“Softens up” local space-time for hostile extradimensional entities: elemental spirits, demons, nightmares from the Dream World, goateed mirror-universe selves, Things Man Was Not Meant To Know, or worse. These attack everyone in the area from the safety of their native realm(s). Every turn, roll for each victim:

Direction (Roll 1d)
1 – Behind! Normally, no defense possible.
2-3 – Left (2) or right (3) side. Defenses are at ‑2. Shield or weapon on opposite side cannot defend.

Null Sphere (VH)
Missile

Creates a sphere of black nothingness in one hand – a tiny gate to another dimension! This can be thrown against a wall, floor, etc. (+4 to hit), or at an individual. It has Acc 2, 1/2D 40, Max 80. Roll against Innate Attack (Projectile) to hit.

On striking its target, the sphere collapses, momentarily exposing this universe to the alien one beyond the gate. This realm has natural laws inimical to the very existence of regular energy and matter.

Everyone nearby must roll against HT, at ‑1 per full four points of energy in the spell but +1 per yard from the point of impact. If the net modifier is +6 or better, the effect is too weak; don’t bother rolling. This checks structural integrity, not vigor; it’s unaffected by Fit/Very Fit or types of Resistant that aren’t explicitly effective against disintegration (notably, Resistant to Metabolic Hazards does nothing).

Failure means the victim suffers 2 HP of injury multiplied by margin of failure. The only DR that protects is that of a reality-stabilized force screen (GURPS Ultra-Tech, p. 192). If damage type matters (say, for Vulnerability), treat this as corrosion – the target is partially disintegrated.

Cost: Any amount up to four times your Magery level per second, for three seconds. Minimum 4 energy.
Time to cast: 1 to 3 seconds.
Prerequisite: Magery 5 and Create Gate.

Splat (VH)
Area

Briefly opens a connected pair of “doors” (see Create Door, GURPS Magic, p. 84) in the area: one atop horizontal surfaces in the area, one above them. Anyone on the ground or an inanimate object “falls” through the lower door, emerges from the upper one, falls again, and so on, accelerating under gravity – and then the portals close, slamming victims into whatever was supporting their weight a moment ago.

Treat this as a five-yard (velocity 10) fall, usually onto a hard surface; see Collisions and Falls (pp. B430-431). This deals 2d crushing to victims with HP 8-12, plus an extra 1d per +5 HP; e.g., 3d at HP 13-17.
This is standard falling damage – Hit Location from a Fall (p. B431) applies and armor counts as “flexible.” For those on chairs, tables, etc., maximum falling damage equals DR + HP of the furniture; this much damage also breaks the object.

As victims have no idea where the ground is until it suddenly appears, it’s difficult to use Acrobatics to mitigate this fall.
Roll at a basic ‑10, but being on the receiving end of this spell in the past gives +1 per experience until the penalty is just ‑5.

On landing, victims who remain capable of standing have to roll against Body Sense, Acrobatics-3, or DX-6. Success lets them land on their feet and act normally. Failure means falling down and being forced to Do Nothing next turn; critical failure, falling down physically stunned!

This is also a Movement spell.

Duration: The spell lasts an instant, but disorientation persists as noted above, and injury remains until healed.
Base cost: 5. Minimum radius two yards.
Time to cast: 3 seconds.
Prerequisites: Magery 4 and Create Door.

Disinfect (VH)
Area; Resisted by HT

This extreme version of Remove Contagion (GURPS Magic, p. 90) doesn’t limit itself to mere microbes. It aggressively cleanses the area in a way that’s no safer for living beings than being autoclaved, bleached, fumigated, and irradiated.

All living things in the area must resist with HT. Failure means suffering toxic injury; DR has no effect. The amount of injury varies with the energy put into the spell, but even the lowest level produces the effects of Remove Contagion. Higher levels are intended to eliminate insects, rats, etc., but aren’t exactly healthy for larger life forms.

This spell is similar to Death Field (p. 11), except that it trades being unable to affect the undead for a higher damage range and a useful sterilization effect.

Duration: The spell lasts an instant, but sterilization lasts until the area is reinfected and injury remains until healed.
Base cost: 2 to 10; injury is 1d HP per two energy points put into the base cost. Minimum radius two yards.
Time to cast: 1 second per two energy points of base cost.
Prerequisites: Magery 4 and at least 10 Healing spells, including Cure Disease and Remove Contagion.

「[[L-幻覚・作成系呪文>GURPS Magic: Artillery Spells#Illusion]]」

原書表記

Illusion and
Creation Spells
Area spells in this college – like Complex Illusion, Perfect Illusion, Phantom Flame, and Simple Illusion – already offer battlefield-control potential. But aside from Phantom (GURPS Magic, p. 97), which causes genuine physical harm unless “resisted,” results depend on enemies’ responses. Even if the GM is generous when roleplaying these reactions, mass-damage results are improbable.

True artillery here is likely to riff on Phantom and produce illusions dangerous to the weak-minded, or else to dip into the college’s creation side to conjure tangible threats.

Create Trap (VH)
Area
Fills the area with artificial h azards o f t he c aster’s choice – not beings (see Creeping Plague, pp. 10-11), deadly energies (electricity, fire, lasers, etc.), or diffuse fluids (acid, lava, steam, and so on), but artifacts of the sort possible for Create Object (GURPS Magic, p. 98). This means things like razor-edged wire, whirring saw blades of enormous size, and toothed snap-traps. The specifics don’t change the spell’s effects.

Anybody moving across the ground must roll vs. DX or DX-based Traps, at ‑2 in either case, every second. Failure deals dice of cutting damage equal to half the margin of failure, rounded up: 1d on failure by 1 or 2, 2d on failure by 3 or 4, and so on. This is large-area injury (p. B400); there are too many simultaneous dangers for any one piece of armor to protect fully.

Travel is also slowed, as victims tiptoe around or extract themselves from trap after trap: Ground movement costs +1 movement point per hex; see Movement Point Costs (p. B387). This makes escaping the area difficult……

Although Traps skill can help avoid the area’s perils, it cannot disarm them. While the spell endures, any trap triggered or defeated is replaced instantly!

Duration: 5 seconds.
Base cost: 5. Minimum radius two yards. Cannot be maintained.

Mirror, Mirror (VH)

Area; Special Resistance

This Phantom variant creates one illusory foe per sentient (IQ 1+) being in its area of effect. Each such subject must resist using the highest of IQ, Will, or Per. It’s possible to be wise enough to recognize illusion magic, resolute enough to reflexively disbelieve conjured entities, or canny enough to know when sight, sound, and scent don’t agree.

Subjects who resist see their illusionary foes fizzle instantly. Those who fail now face shadowy versions of themselves. Each victim’s opponent appears directly ahead – a yard away if possible, in close combat if not – and attacks much as a Phantom spell would. It can strike, grapple, etc. as if real. Combat stats are identical to the subject’s, but ST and DX cannot exceed the mage’s skill with the spell, which can limit damage, Basic Speed, Move, skills, active defenses, etc.

Example: Mirror, Mirror is cast at skill 16. An ogre with ST 20 and DX 9 would face a phantom ogre with DX 9 but just ST 16, which would mean less damage. A ninja with ST 11 and DX 17 would face a phantom ninja with ST 11 but only DX 16, and therefore lower Basic Speed, skill, and defenses.
As with Phantom, this entity doesn’t have DR or HP, or suffer normal injury. Instead, it has a damage threshold equal to the caster’s margin of success. Any single attack on the phantom that inflicts this amount (or more) of basic damage immediately dispels it; lesser attacks accomplish nothing.

Materialized phantoms have substance for everyone.
Thus, anybody may attack one. However, a given phantom only ever attacks its designated victim, maneuvering to stay close to its target. If that person is knocked out or killed, their shadow-self is dispelled – the entity doesn’t stick around to fight others.

This spell doesn’t produce a persistent effect on the area. I t a ffects o nly s ubjects t here a t t he i nstant o f c asting.
The phantoms it creates can move beyond the area to pursue their designated victims until dispelled or the spell ends, however.

The entities called up by this spell are already extraordinarily autonomous and cannot be further enhanced with Independence or Initiative. Dispel Illusion and Control Illusion do work, but must affect individual phantoms one at a time.

Duration: 1 minute or until all the phantoms are destroyed, whichever comes first.
Base cost: 10. Half that to maintain. Minimum radius two yards.
Time to cast: 1 second per yard of radius.
Prerequisites: Magery 4, Initiative, and Phantom.

Sunburst (VH)
Missile

Creates a glowing energy ball – resembling a miniature sun – that can be hurled from one hand. This has Acc 1, 1/2D 25, Max 50. Roll against Innate Attack (Projectile) to hit. It can be thrown at a foe, or (at +4 to hit) at a wall, floor, etc.

Upon striking a solid target, this projectile flares with unbearable brilliance. This acts as an enhanced Flash spell (GURPS Magic, p. 112): Victims’ HT rolls are at ‑1 per full four energy points in the spell.

Creatures with a Weakness to bright light or sunlight, or that suffer extra harm from light-based attacks (e.g., due to Vulnerability), take damage on top of the flash effect. Divide this by distance in yards – not triple that, as with typical explosions. As for any explosion, this is large-area injury (p. B400). Wounding multipliers from Vulnerability or equivalent flaws increase any injury caused.

Example: A Sunburst containing 12 energy points goes off. For most people, this acts as a potent Flash spell – someone facing the burst must roll vs. HT‑3 to avoid the worst effects (DX penalties and/or blindness). A vampire (p. B262) with Weakness (Sunlight) would also experience a 6d burning explosion; at three yards, damage would be divided by 3.
A being in Shadow Form (p. B83) – like a spirit summoned by Animate Shadow (Magic, p. 154) – would suffer the same damage and increase final injury by 50%.

Cost: Any amount up to twice your Magery level per second, for three seconds. The burst does 1d burning explosive damage to susceptible targets per full two points of energy and gives ‑1 to resist the flash per full four points.
Time to cast: 1 to 3 seconds.

Sun’s Arc (VH)
Regular

Shoots a beam of searing light from one hand. This plays over an area equivalent to that of a cone 10 yards long by five yards wide at its far end. This isn’t a true cone, however, and doesn’t use Cone Attacks (p. B413).

Going from left to right or right to left (caster’s choice), roll vs. Innate Attack (Beam) to hit each target in the affected wedge. Anybody completely screened from the caster is behind cover. When in doubt, ask whether there would be penalty to hit with a ranged attack; see Firing Through an Occupied Hex (p. B389). If not, the target is valid.

Otherwise, treat these attack rolls as melee attacks, as if attacking with an unusually long Flame Jet or a Light Jet.
Valid hit locations are fuzzier than usual: “high” (face, at ‑5), “middle” (torso, at no penalty), or “low” (legs, at ‑2). Targets may dodge or block normally.

The beam is too narrow to inflict large-area injury, but sufficiently broad that if it hits the face, beings with eyes must roll vs. HT if they suffer any injury. Failure means being blinded; treat this as a crippling injury for recovery purposes (p. B420).
If the ray plays across the legs, roll damage separately for each leg – but maximum injury to a leg is a crippling wound, and the beam cannot cause dismemberment.

Duration: The spell lasts an instant, but blindness persists as noted above, and injury remains until healed.
Cost: 5 to 15, for 1d tight-beam burning damage per full five energy points.
Prerequisites: Magery 4 and at least 10 Light and Darkness spells, including Light Jet and Sunbolt.

「[[L-物体操作系呪文>GURPS Magic: Artillery Spells#Making]]」

原書表記

Making and Breaking magic cannot affect living targets, but that doesn’t prevent it from doing damage to everybody when it destroys objects – witness Explode (GURPS Magic, p. 118). Artillery in this college is usually a variation on this theme.

The GM contemplating “mass” variants of Disintegrate, Explode, or Shatter – or even of low-powered spells like Weaken or Ruin – is advised to think twice. Magic that aims to destroy every object (including personal gear) in an area is unlikely to be balanced, and certain to involve too much dice-rolling.

Explosive Mine (VH)
Regular

A small patch of ground – one hex on a battle map – becomes magically unstable. There’s no mundane way to spot the trap, but it’s obvious to Detect Magic, Mage Sight, and so on.

The first time anyone or anything weighing at least 5 lbs. moves onto the subject hex, the ground itself explodes and the spell ends. This does crushing explosive damage, plus incidental fragmentation (1d‑4 cutting per fragment) to everyone within five yards.

Falling onto an Explosive Mine is deadly! This is a contact explosion, meaning the victim takes maximum possible damage (but protects others with “cover DR” equal to torso DR + HP).

Also roll the spell’s damage dice against the ground or floor itself. If this reduces the surface to 0 or fewer HP, it leaves a crater that counts as bad footing. If there’s open space underneath, this is an actual hole to the level below, 2” in diameter per damage die.

Duration: 1 minute or until triggered.
Cost: Any amount up to four times your Magery level. For every full two energy points in the spell, the mine does 1d crushing explosive damage. See Explosions (p. B414) for rules for explosive damage. Cannot be maintained.
Prerequisites: Magery 3 and at least 10 Making and Breaking spells, including Explode.

Minefield (VH)
Area

Mines an area at random – even the caster has no idea where the mines are! The first time anyone or anything weighing 5 lbs. or more moves onto an affected hex, roll 1d. On 1-3, nothing happens; there’s no mine there. On 4-6, there was a m ine but t here i sn’t a ny more, b ecause i t e xplodes, exactly as per Explosive Mine (above). Either way, mark the hex as cleared.

This spell can be tremendously slow and energy-intensive – 12d mines are deadly, but someone with Magery 6 must invest 24 energy points multiplied by radius and spend 12 seconds to fill an area with them. Don’t overlook lower levels, though. A paltry base cost of two energy points can, in a mere second, seed half the hexes in the area with 1d mines that are more than enough to ruin the day of “cannon fodder.”

Duration: 1 minute or until the entire minefield is cleared, whichever comes first.
Base cost: Any amount up to four times your Magery level.
For every full two energy points of base cost, each mine does 1d crushing explosive damage. See Explosions (p. B414) for rules for explosive damage. Minimum radius two yards. Cannot be maintained.
Time to cast: 1 second per die of damage.
Prerequisites: Magery 4 and Explosive Mine.

「[[L-呪文操作系呪文>GURPS Magic: Artillery Spells#Meta]]」

原書表記

Battlefield control with Meta-Spells involves erecting barriers to enemy magic (e.g., Spell Shield), tearing down rival spells (Dispel Magic affects an area), or rendering the combat zone inimical to magical foes (Pentagram and Drain Mana work well, and also interfere with spells). Using Link to salt an area with magical “mines” is strategic, too. Such options are mostly slow and work best on the defensive, with time to prepare.

To give meta-mages damage-dealing capacity, the GM can opt to treat “magical energy” as a destructive force in its own right, capable of doing harm if focused. This might affect magical creatures or everything.

Mana Storm (VH)
Area

Fills an area with intense magical fluctuations that tear away at the magical essence of anything that has an “aura.” Every living or undead creature with IQ 1+ (including elves, humans, Martians, vampires, werewolves, and all other tangible, self-motivated beings) has an aura and is affected. The same is true for all IQ 1+ spirits and entities animated by spirits; e.g., golems. Creatures with IQ 0 – and illusions, creations, and inanimate things (like computers), regardless of IQ – lack auras and are immune.

For as long as the spell endures, all such beings that remain in the area lose 1 HP per second. This injury bypasses DR, but Magic Resistance bestows immunity for seconds equal to its level. Treat this delay as “virtual HP” that regenerate at a rate of one point every 10 minutes; e.g., Magic Resistance 5 buys five seconds, after which injury accrues normally until at least 10 minutes are passed outside any Mana Storm.
This effect isn’t blocked by countermagic such as Spell Shield, but can be dispelled like any other magic. If the area overlaps a no-mana zone, there’s no effect on beings in the zone.

Duration: 10 seconds.
Base cost: 3. Same cost to maintain. Minimum radius two yards.
Time to cast: 1 second per yard of radius.
Prerequisites: Magery 4, Drain Mana, and Restore Mana.

Punishment Circle (VH)
Area

Creates an area that inflicts pain and injury upon magical creatures. This zone affects any entity that’s summoned or could be summoned (e.g., angels, demons, elementals, and other spirits), beings called into existence by magic (creations, illusions, phantoms, etc.), constructs (such as golems), the undead, and individuals with Dependency on mana or Weakness to its absence. Spellcasters don’t count unless they also belong to one of those categories.

When the spell is cast, a glowing, rune-edged circle immediately surrounds the area. This is obvious to all kinds of vision and to the special senses (Detect, Magery, Scanning Sense, etc.) of magical creatures. A full circle is thaumatologically significant – the spell encompasses the whole area paid for, no “holes” allowed, and if this overlaps a no-mana zone, the casting fails automatically.

For as long as the spell endures, magical creatures that remain in the area lose 1 HP per second. This injury is painful: Victims have a constant shock penalty (p. B419) of ‑2 on any turn after losing HP. High Pain Threshold merely halves this to the usual ‑1; Low Pain Threshold doubles it to ‑4! Beings with IQ 0-5 must make a Will roll at this shock penalty to stay in the circle; failure compels them to flee as if due to Dread (pp. B132-133).

If injury from a Punishment Circle leads to unconsciousness or death for a creature that could be dispelled or banished, the entity experiences that fate a s well, vanishing at once and leaving behind anything it didn’t arrive with: stolen items, screaming victims, etc.

This is also a Necromantic spell.

Duration: 1 minute.
Base cost: 3. Same cost to maintain. Minimum radius two yards.
Time to cast: 1 second per yard of radius.
Prerequisites: Magery 3 and either Pentagram or Repel Spirits.

Mind Control Spells
Mind Control offers Mass Daze, Mass Sleep, Panic, Terror, and several other Area spells suitable for battlefield control. Its magic never inflicts damage directly, however, and adding that capacity to such a powerful, well-endowed college isn’t recommended. On the other hand, compulsions to do harm that go beyond vague suggestions or hostile emotions are on-message!

Below are two examples. As usual for Mind Control, they affect only beings with racial IQ 6+ and free will.

Mass Mutilation (VH)
Area; Resisted by Will

　This variation on Mass Suggestion (GURPS Magic, p. 141) is faster to cast and far shorter-lived and more specific: Subjects who fail to resist must use their next combat maneuver to try to harm themselves.
Subjects with suitable ready weapons take Attack or Ready maneuvers to use these on themselves. The GM decides what’s “suitable” in the space of a turn. It’s plausible to cut oneself with a blade, shoot oneself with a gun or crossbow, arm a grenade and hold on to it, or deliberately mishandle a Missile spell or Molotov cocktail. Falling upon a 15’ pike or turning a longbow around fails a reality check.

If a suitable weapon is to hand, skip attack and defense rolls; just roll damage against the torso. Attacks must use the deadliest attack mode, if there’s a choice (GM’s decision, remembering that the target is the torso) – and no “pulling punches.” Anyone who can Fast-Draw a weapon (or a better weapon) does so; e.g., a barehanded fighter with a knife Fast-Draws it and starts cutting, while someone holding a knife and wearing a sheathed sword drops the knife, Fast-Draws the sword, and falls on that.

Subjects without suitable weapons do something else that’s liable to get them killed. They might use Move to run as close as possible to the nearest enemy; if several foes are equidistant, choose one at random. If a hazard – lava pit, cliff, persistent artillery spell, etc. – is closer, they’ll hurl themselves at that instead. In either case, they choose to let their guard down: no active defenses, DX rolls not to fall in, or anything similar.

Duration: 1 second – long enough for every affected subject to take one turn. Self-inflicted injury remains until healed.
Base cost: 4. Minimum radius two yards. Cannot be maintained.
Time to cast: 1 second per yard of radius.
Prerequisites: Magery 4 and at least 10 Mind Control spells, including Madness and Mass Suggestion.

Stabbing Party (VH)
Area; Resisted by Will

Another swift, short-lived, highly specific Mass Suggestion variant. Those who fail to resist must use their next combat maneuver to attack the nearest ally (never an enemy or neutral party); if several are equidistant, choose one at random.
Subjects with no allies on the battlefield are unaffected.

A subject with a ready ranged attack (bow, spear, Missile spell, death gaze, etc.) uses it, usually meaning an Attack maneuver. One with only melee attacks chooses Attack if the nearest ally is within one step, All-Out Attack (Strong) if the target is farther away but within half Move forward, or Move and Attack if those options are impossible. A subject who can’t attack the nearest ally in one turn prepares to do so, dropping a melee weapon to Ready a ranged one, using Concentrate to cast a Missile spell, or – if without a ranged attack – taking a full Move toward the chosen target.Movement is always as direct as possible, without regard for battle formations or who ends up behind whom.

Subjects suffer unavoidable penalties for their attacks (e.g., distance and visibility for ranged attacks, or the Move and Attack penalty), but won’t take optional penalties for hit location, Deceptive Attack, Rapid Strike, etc. unless final skill would be 16+. Similarly, they won’t try to “spoil” attacks by, for instance, taking Move and Attack if they could Attack, or shifting their weapon to the off hand. For one turn, they truly want to kill their allies.

Attacks must likewise be as damaging as possible, never “pulling punches,” always choosing the Strong option if making an All-Out Attack, and using the deadliest attack mode or weapon (GM’s decision) if there’s a choice. Anyone who can Fast-Draw a better weapon does so; e.g., someone holding a dagger and wearing a holstered pistol drops the blade, Fast-Draws the gun, and shoots. If this means expending a one-shot item (even a Doom Wish, pp. 13-14), expensive Missile spell, or limited-use ability, too bad!

Targets of these attacks may defend normally if they see them coming. Attacks from allies are likely to come from the back (no defense) or side (‑2 to defend), however.

This spell is no cheaper than Mass Mutilation (p. 20).
Though it’s likely to cause fewer casualties – not everyone is guaranteed to have an ally to attack, and active defenses are permitted – it’s more likely to scatter enemy formations and more useful against foes that can’t easily harm themselves (wielding long weapons, immune to their own attacks, etc.).

Duration: 1 second – long enough for every affected subject to take one turn. Tactical confusion lasts as long as it takes to resolve and injury remains until healed.
Base cost: 4. Minimum radius two yards. Cannot be maintained.
Time to cast: 1 second per yard of radius.
Prerequisites: Magery 4 and at least 10 Mind Control spells, including Command and Mass Suggestion.

Standard Movement magic includes no mass-damage spells – though Pull is great for dragging victims into an area, and Glue and Grease for keeping them there, making the artillery of other colleges deadlier. Artillery added to this college typically slams around everything in an area or turns dangerous objects into airborne hazards.

Collision (VH)
Regular

Briefly creates a high-powered Pull (GURPS Magic, pp. 146-147). This must be cast on a point in space or on the ground, not on an object or creature.

At its center, the pull’s ST equals twice the energy points in the spell; each yard of distance reduces ST by one. The moment the spell is cast, animate beings nearby must roll a Quick Contest: their ST vs. the spell’s. Those who weigh more than 20 lbs. times the spell’s ST – that’s 20 lbs. \ (ST-1) at one yard, 20 lbs. \ (ST-2) at two yards, and so on – are unaffected. There’s no time to grab anything, but people already hanging onto any person or object (see below) the spell cannot affect may add +2 ST per hand used, while anyone grappled by a foe too heavy to budge rolls only if their rival chooses to let them go. Losing the Contest means being yanked into the center; victims and their possessions are pulled (or not) as a unit. There’s no fixed Move as with Pull – everything arrives at high speed!

Don’t roll Contests for inanimate objects. They’re pulled to the center unless they are fixed in place or weigh more than 20 lbs. times the spell’s ST. The GM is encouraged to simplify; e.g., in a quarry, all that’s important is that some rocks move.

If there are no movable objects nearby and just one victim, the only effect is being hauled into the center. If there are two or more people and/or solid objects, though, they crash together at the center, much as if hurled by Poltergeist (Magic, p. 144). Don’t work out detailed collision damage from speed and HP – damage is a flat 2d+2 crushing for everyone involved (and important objects). This is large-area injury (p. B400).

After the collision, victims are clustered around the center. On a battle map, the GM may position them in the center hex or adjacent hexes. Combatants retain their original facings, but those whose injuries haven’t caused them to fall down must roll against the highest of DX, Acrobatics, or Judo to avoid falling down.

Duration: The spell lasts an instant, but tactical confusion lasts as long as it takes to resolve and injury remains until healed.
Cost: 1 for every 2 ST of “pull.” Minimum ST 16.
Time to cast: 3 seconds.
Prerequisites: Magery 4 and at least 10 Movement spells, including Poltergeist and Pull.

Crushing Fist (VH)
Area

Similar to Distant Blow (GURPS Magic, p. 144), but speedy to cast, works once, and attacks an area. It affects only the caster’s hand: A gigantic replica of the wizard’s fist appears overhead and pounds everything beneath it!

When the spell is cast, everything within the area is bashed by the giant fist of force. The only possible defense is to dive for cover to leave the area (p. B377). No other active defenses are effective. Those who fail to escape are pummeled for largearea injury (p. B400).

The caster’s magical strength – not physical might – determines damage. Work out punching damage (thrust-1 crushing) using the wizard’s IQ + Magery as effective ST; e.g., a lich with IQ 16 and Magery 6 would have ST 22 and deal 2d-1 crushing. Unlike most artillery spells, where damage depends on energy cost, this one gets deadlier “for free” as the wizard grows in power.

Duration: The spell lasts an instant, but injury remains until healed.
Base cost: 3. Minimum radius two yards.
Prerequisites: Magery 4 and at least 10 Movement spells,
including Distant Blow and Wizard Hand.

Slasher (VH)
Area

Propels a cutting weapon through the area as if wielded by an invisible mad slasher. It must start in the caster’s hand. When the spell is cast, the blade takes wing and whirls through the air too quickly for the eye to follow.

Everybody in the area is attacked each turn, on their turn, at skill 15. The victim can try a Hearing roll at ‑2 to detect the weapon’s whine; success permits any active defense, while failure allows only a dodge. All defenses are at ‑4 for an unseen attacker. Also roll 1d for the attack’s origin: 1-3 is front, 4 is right-hand side (another ‑2 to defend), 5 is behind (no defense), and 6 is left-hand side (‑2 to defend).

A hit damages a random hit location. Use the weapon’s usual swung cutting attack as if swung with ST 15, for a basic swing damage of 2d+1.

It’s possible to break or grab the animated weapon. This requires a Hearing roll at ‑2 first. Success allows an attack on the blade at a basic ‑6 plus the usual ‑3 to ‑5 for weapon size (see Striking at Weapons, p. B400). The weapon cannot defend. Breaking it ends the spell. Grabbing it doesn’t; it may try to break free each turn with ST 15.

The caster can animate several weapons at once: a blade in either hand, even a fistful of knives (one hand can hold weapons weighing up to BL). Find energy cost from total weight. This doesn’t give more attacks or damage. It does means that disabling a single weapon won’t prevent attacks, and it may increase the odds of a hit: add the bonus under Rapid Fire (p. B373) to skill, reading “shots” as “weapons.” If the weapons aren’t alike, choose which hits each target – or is neutralized by enemy action – at random.

Example: A wizard animates six small knives (total 3 lbs.): two fine-quality and four good-quality. This makes base cost 6. The knives have skill 15 + 1 (for six knives) = 16. A hit has a 2 in 6 chance of inflicting swing‑3 +1 (for fine quality), or 2d‑1 cutting and a 4 in 6 chance of 2d-2 cutting. Two must be neutralized to reduce skill to 15, and all six to prevent attacks.

Unlike many Area spells, this one can be cast on one hex (radius one yard), making it efficient for defending narrow passages.

Duration: 5 seconds or until all the weapons are destroyed, whichever comes first.
Base cost: 2 per pound of total weapon weight. Minimum weight 1 lb. Cannot be maintained.
Time to cast: 1 second per yard of radius.
Prerequisites: Magery 4 and at least 10 Movement spells, including Dancing Object and Winged Knife.

Necromancy has a ghastly reputation, but it does most of its bad things to one good person at a time. The closest it has to artillery is Turn Zombie (which blasts a narrow class of targets) and Mass Zombie (which conjures an army). Yet many of its injurious effects are easily extended to groups.

Below is one example. For others, see Plague Touch (p. 11) and Punishment Circle (pp. 19-20). Hell Zone (p. 16) counts as well, in settings where Summon Demon is the only widespread Planar Summons spell.

Spirit Incursion (VH)
Area

Conjures evil spirits related to those called by Skull-Spirit (GURPS Magic, p. 151). But instead of a single entity that serves obediently for 24 hours and is free to roam, this spell brings an indeterminate number of spirits that stay for mere seconds, are bound to a place, and don’t distinguish friend from foe. Each turn, every living creature (only!) in the area suffers 1 HP of toxic injury, which bypasses all DR.

Attempts to battle the entities this spell conjures are pointless – the magic brings a steady stream of spirits that partially materialize where the victim cannot see them, take a “bite,” and then vanish into the Spirit World. Neutralizing a small number would change nothing. However, Repel Spirits excludes these beings unless Spirit Incursion can beat it in a Quick Contest, while Astral Block prevents them from partially materializing to attack. Either situation means people inside the area of the defensive spell are safe.

Duration: 10 seconds.
Base cost: 3. Same cost to maintain. Minimum radius two yards.
Time to cast: 1 second per yard of radius.
Prerequisites: Magery 4 and at least 10 Necromantic spells, including Skull-Spirit.

“I’ll Take You All With Me!”
Brave-hero and sore-loser wizards might decide it’s better to go out in a blaze of glory or vengeance than to risk the alternatives.
Magical ways to accomplish this include smashing a Vengeful Staff (p. 14) and casting an explosive or area-effect artillery spell at your feet – ideally when surrounded by the enemy.

In some settings, there may be a special spell for this. If you learn it, be aware that if foes who can control minds even suspect you know it (mind-controllers are often mind-readers . . .), you’re a walking powder keg. The last words you and your allies hear might be, “Cast Self-Destruct!”

Self-Destruct
Regular
Blows up the caster at once. If the spell works, the wizard’s body immediately explodes much as for Fragile (Explosive) (p. B137), except as a consequence of magical overload rather than physical instability: the crushing explosion causes a basic 6d×(IQ + Magery)/10 damage; e.g., 10d with IQ 14, Magery 3.
If the casting leaves the (former!) magician with unspent FP or Energy Reserve that could have powered the spell, add 1d to the blast per full 10 e nergy p oints. E veryone w ithin five yards also risks being hit by bones, teeth, shattered gear, and so on, for 1d cutting damage; see Fragmentation Damage (pp. B414-415).

The caster is reduced to ‑10×HP regardless of damage inflicted, and cannot be resurrected – there isn’t enough left.
The fate of gear is up to the GM. Most equipment is destroyed, but for anything important, assess damage against DR and HP.

Morally and theologically, treat this spell as the equivalent of any kamikaze – one person’s sacrifice to slay legitimate enemies is another’s terrorist act.

This spell might belong to any number of colleges. Explosions suit Fire, but a magical overload suggests Meta-Spells and suicide smells Necromantic.

Duration: The spell lasts an instant, but injury remains until healed – and the caster and any gear destroyed are gone for good!
Cost: 12. The caster simply needs to have the energy; the details won’t matter much once the spell is cast. Still, suicidal wizards should note that while Burning HP (GURPS Magic, p. 8) is logical, the penalty it gives can cause the casting to fail.
Prerequisites: Magery 1 and at least one spell from each of 10 different colleges. The GM may prefer something like 10 Fire spells, 10 Meta-Spells, or 10 Necromantic spells. To increase the barrier to access, add Explode (which implies Magery 2).

Plant Spells
Plant artillery exists already: Pollen Cloud, Rain of Nuts, and Tangle Growth are like less-lethal ammunition, while Wither Plant is an area-effect death spell – against plants. GURPS Magic: Plant Spells presents more options, some of which (like Bloodsucking Branches and Razor Grass) can harm everyone in an area. Most such effects require the presence of plants, however, whether as their source or as their target.

Here are two possibilities for fantasy druids who need firepower when they aren’t out in Nature or battling plant monsters.

Devil’s Dust (VH)
Area; Resisted by HT

A cloud of magically allergenic pollen fills the area. This is a contact agent; it needn’t be inhaled to be harmful. Thus, Doesn’t Breathe, Filter Lungs, and breath-holding are ineffective!

Living beings in the area must resist the spell each turn or suffer toxic shock causing 1d HP of injury (DR has no effect). If any resistance roll fails, they also suffer the effects of Pollen Cloud (GURPS Magic, p. 162): ‑2 to DX – in this case, the special effects are itching and burning – until the spell dissipates or they leave the area, and for 3d seconds afterward.

Resistant and Immunity to Poison don’t help against Devil’s Dust. Resistant to Metabolic Hazards does add its bonus to resist, and Immunity to Metabolic Hazards or Sealed grants immunity.

The pollen doesn’t persist for long enough for its movement or dissipation by wind to become an issue.

Ironweed (VH)
Area

Causes the ground to sprout pointy, iron-hard shoots that behave as a dense field of miniature caltrops. These spring from soil like ordinary plants, appear as though shaped from a wooden floor, force their way up between bricks or cobbles, and create cracks in porous stone or concrete. Only seamless, nonporous ground in the area – like a sheet of metal, glass, or plastic flooring – remains unaffected.

Each turn, everybody on foot in an Ironweed field automatically steps on one spike plus one per yard traveled within the area. Falling down among the barbs means being stabbed SM+4 times; e.g., four times for an SM 0 human or five for an SM +1 ogre. There are no rolls to avoid these fates – the shoots are too closely packed!

Each sprout does thrust-3 impaling damage, based on the victim’s ST, to a randomly chosen foot – or, on a fall, to a random hit location. Minimum basic impaling damage is 1 point per attack (p. B378). Any DR protects normally. Impaling damage isn’t doubled against limbs or extremities (such as the feet); see p. B399. Maximum injury is 2 HP per barb, but keep track of it – accumulated wounds (p. B420) can cripple.

Example: An ogre with ST 21 (thrust 2d), DR 3 skin, and DR 2 boots runs three yards through the area. That means being stabbed 1 + 3 = 4 times in the feet. Each shoot does 2d‑3 imp vs. DR 5; a roll of 9 or more on the dice is needed to get past DR, but even a roll of 11 or 12 inflicts just 2 HP. A typical ST 10 (thrust 1d-2) peasant without DR would suffer 1d-5 imp each time – or 1 HP per barb, with minimum impaling damage.

While easy to learn, cheap, long-lasting, and not very damaging, this spell is artillery. A caster with a lot of energy could blanket the entire battlefield and bloodily cripple all DR 0 “fodder” in a few turns with little inconvenience to armored allies.

Duration: 1 minute.
Base cost: 1. Same cost to maintain. Minimum radius two yards.
Time to cast: 1 second per yard of radius.
Prerequisites: Magery 1, Essential Wood, and Plant Growth.

「[[L-防御・警戒系呪文>GURPS Magic: Artillery Spells#Protection]]」

原書表記

Protection and Warning spells can control the battlefield. Mystic Mist is incredibly cost-effective on the defensive, afflicting foes (but not friends!) with obstructed vision, reduced defenses, confusion, and fear. Less passively, Force Dome can end fights by imprisoning the enemy, while Atmosphere Dome can do real harm to those inside.

Still, the best defense is a good offense, and the absoluteness of Force Dome and Force Wall (GURPS Magic, p. 170) practically begs use as artillery.

Diminishing Dome (VH)
Area

Creates a Force Dome that lasts for just long enough to appear, shrink (squashing its contents), and then collapse. Once the spell is cast, the dome takes a full second to form. This is obvious, and everybody within the area has one turn to leave.

On the caster’s next turn, the dome shrinks out of existence. Magical creatures inside it – anything Pentagram (GURPS Magic, pp. 124-125) could affect, including creations, demons, elementals, golems, spirits, and undead – are unaffected as the moving surface of force washes past them. But everybody else in the dome is dragged into the center, regardless of ST.

Unlike Black Sphere (GURPS Magic: Death Spells, p. 20), this isn’t an instant-death effect – at some point, the dome’s contents push back forcefully enough to break the spell. Still, it isn’t healthy: Everyone remaining in the area suffers 4d crushing damage as large-area injury (p. B400).

The GM decides how cramped things get before the dome expires, as well as where people end up. On a battle map, five human-sized victims per hex works. The number of hexes in radius R is 3\R2 ‑ 3\R + 1, so if matters, final radius ends up being one yard for up to five victims, two yards for up to 35, three yards for up to 95, and so on. Multi-hex figures count as one victim per hex of size, and may be forced into unnatural positions. Anybody crushed into the same hex as a being with Spines or an Aura is affected.

This spell is cheap to cast because for small areas, it’s unlikely to catch many victims unless the battlefield itself is restrictive – everybody who can leave will!

Duration: 1 second – long enough for the dome to form and shrink. Tactical confusion lasts as long as it takes to resolve and injury remains until healed.
Base cost: 4. Minimum radius two yards. Cannot be maintained.
Prerequisites: Magery 4 and Force Dome.

Force Ball (VH)
Missile

Creates a miniature Force Dome in one hand that can be hurled at an enemy. This has Acc 2 and Max 80, but no 1/2D. Roll against Innate Attack (Projectile) to hit. On striking its target, the ball delivers a crushing blow – much like Ice Sphere or Stone Missile – and then pushes off from its target, leading to two important differences.
First, this doubles damage for knockback purposes only; e.g., a hit that does 14 points of crushing damage would do knockback as for 28 points. Knockback pushes the victim away along the line of fire.

Second, if the missile hits, it regains some energy and ricochets toward a new enemy of the caster – the foe closest to the previous victim’s location prior to knockback. The ball is now guided by magic; roll against the wizard’s Force Ball level rather than Innate Attack skill. The only modifiers that matter are range penalties for the distance between targets and ‑5 if the trajectory crosses low mana; the projectile ignores poor visibility and steers deftly around obstructions.

The secondary target is hit for 1d less damage, still doubled for knockback – and then the ball seeks out the nearest foe it hasn’t attacked yet. This continues until the missile fails an attack roll, runs out of new targets, reaches zero dice of damage, or travels a total of 80 yards in its quest for enemies, whereupon it expires.
Those hit by a Force Ball may dodge or block. Success prevents damage but doesn’t stop the missile from ricocheting toward someone else.

Example: Juniper has Innate Attack-14 and Force Ball-16, and hurls a 6d Force Ball at an orc three yards away; she has skill 14 ‑ 1 (range) = 13, rolls a 12, and hits. The orc fails to defend, and suffers 20 points of crushing damage, which counts as 40 points for knockback. The spell is now at 5d, and the next-nearest enemy is two yards away (no range penalty); the spell rolls to hit at 16 and succeeds. This continues for two more attacks on other orcs two yards apart, for 4d and 3d damage; one dodges and one doesn’t, but there are no misses.

After that, the only foes not yet attacked are some archers 25 yards away. The missile still has enough damage (2d) and range (total range is 34 yards), but attacks at ‑7 for distance; the spell has skill 16 ‑ 7 = 9, rolls an 11, and misses, so it dissipates instead of seeking another target.
This is also a Movement spell.

Cost: Any amount up to twice your Magery level per second, for three seconds. The ball of force does 1d crushing double-knockback damage per full two points of energy.
Time to cast: 1 to 3 seconds.
Prerequisite: Magery 4, Catch Spell, Force Dome, and Sense Foes.

Improved Concussion (VH)
Missile

As Concussion (GURPS Magic, p. 26), but with a bigger blast radius: targets a yard or more from the center divide damage by distance in yards instead of by three times that.
The radius inside which a HT‑3 roll is required to avoid stun remains 10 yards – but even at 11 to 20 yards, everyone must make a HT roll to avoid stun (and if they succumb, a HT roll each turn to recover). Understandably, range is also greater: Acc 2, 1/2D 40, Max 80.

This is also an Air spell.

Cost: Any amount up to three times your Magery level per second, for three seconds. The blast does 1d crushing damage per full three points of energy.
Time to cast: 1 to 3 seconds.
Prerequisite: Magery 4 and at least seven Sound spells, including Concussion and Great Voice.

Perilous Pulsations (VH)
Area; Resisted by HT

Sets up internal vibrations in all material targets (living or otherwise) within the area of effect. Each turn, everything there must resist the spell or suffer 1d HP of injury as it shakes apart. This compromises armor, tough skin, and so on – DR has no effect.

Unlike many Sound spells, this one doesn’t require an atmosphere and isn’t generally audible. Vibrations are created inside those affected. Everyone within the area is acutely aware of a tooth-rattling whine alongside any pain and injury, however!

Duration: 5 seconds.

Withering Wail (VH)
Regular

Enables the caster to emit a horrible screech at a frequency that disrupts living flesh. Despite doing harm in a radius that depends on the energy spent, this isn’t an Area spell. The subject is also the caster, who must be able to shriek and not Mute (Cannot Speak is fine), gagged, or silenced by a spell such as Garble, Hush, or Strike Dumb.

While the capacity to wail in this way is magical, the sonic effect is not. It can cross no-mana areas but requires a path from caster to target through a fluid medium (e.g., air or water) – that is, if the wizard were hollering normally, the shouts would have to be audible at that person’s location.
The victim needn’t hear the howl, however; deafness, earplugs, etc. afford no protection. Withering Wail must win a Quick Contest against Silence or Wall of Silence to cross such areas.

This spell inflicts generalized injury – both hit location and DR are irrelevant.

Duration: The spell lasts an instant, but injury remains until healed.
Cost: 2 to 10, for 1d HP of injury per two energy points, multiplied by radius in yards; e.g., 18 to inflict 3d in a threeyard radius. Minimum radius two yards. Figure full cost before applying reductions for high skill, as for an Area spell.
Time to cast: 1 second per die of injury.
Prerequisites: Magery 4 and at least 10 Sound spells, including Great Voice and Noise.

Death Ray (VH)
Missile

Shoots a particle beam with Acc 3 and Max 50, but no 1/2D, that has the potential to affect everything along its line of fire. Choose a primary target and roll a standard ranged attack, using Innate Attack (Beam). Hit or miss, draw a line from the attacker, through the target, out to 50 yards: Everything else on that line is also attacked, at the lower of the roll the caster would need to hit or 9 less.

This beam is broad enough to inflict large-area injury (p. B400) and sufficiently penetrating that DR protects at only 1/5 value. As a consequence, targets normally don’t provide cover DR to one another – everything hit takes full damage. However, the ray will stop if it strikes something that has both SM +2 or more and cover DR equal to or greater than five times maximum damage.

Example: Alecks shoots a 6d(5) Death Ray at an orc 10 yards away (‑4 to hit); he has Innate Attack (Beam) at 15, and needs 11 or less. The orcish hordes are arranged in six ranks two yards apart, so there are five more potential targets at 12 (‑5 to hit), 14 (‑5), 16 (‑6), 18 (‑6), and 20 (‑6) yards. The rolls needed to hit these foes on purpose are 10 or less for the first two, 9 or less for the next three, so the beam attacks them all at 9 or less. Just behind the last rank is a foot-thick dungeon wall with cover DR 13 per inch (p. B559), or DR 156 – large enough to stop the ray but not durable enough, as five times maximum damage is 180. Beyond the wall is an orcish chieftain, at 48 yards (‑8 to hit), just inside Max 50; the beam has a 7 or less chance of hitting him as well!

Despite being a Radiation spell, Death Ray does not inflict rads. It is still hard on electronics, though, and has the Surge modifier (p. B105) just like a Lightning spell.

Cost: Any amount up to twice your Magery level per second, for three seconds. The beam does 1d(5) burning damage per full two points of energy. This damage isn’t tight-beam but won’t set fires.
Time to cast: 1 to 3 seconds.
Prerequisites: Magery 4, Lightning, and Radiation Jet.
