GURPSよろず

When creating new abilities – particularly as part of a power – it often makes sense for the GM to build several very similar abilities. For example, he may create two dozen new abilities for a Holy power, where half are “auras of power” that share many modifiers. Bundling these common modifiers into a single meta-enhancement can streamline power-building and simplify the final write-up.
To create a meta-enhancement, just identify which modifiers are common to every one of your builds. Then total them up and treat them as a single enhancement (or limitation). Any unshared modifiers can be added separately. Alternatively – if two or three modifiers aren’t common to all of the abilities, but each is common to several of them – it may be worth creating different versions of the meta-enhancement; see Songs (p. 5) for an example.
The following are meta-enhancements that have appeared in previous GURPS publications.

This is a new special enhancement for Affliction; it must be combined with one or more of Advantage, Attribute Penalty, Disadvantage, Incapacitation, Irritant, or Negated Advantage. Aura of Power is a meta-enhancement that turns the Affliction into a two-yard area effect, centered on the adventurer, that affects any targets he wishes.

Aura of Power (+175%): Area Effect, 2 yards, +50%; Aura, +80%; Malediction 1, +100%; Melee Attack, Reach C, -30%; Reduced Duration, 1/60, Only after the target leaves the area, -30%; Requires Will Roll*, -5%; Selective Area, +20%; Takes Extra Time, -10%.

　* A limitation from Powers. Your switchable ability requires a Will roll to activate, and a further Will roll every minute to maintain. If this roll fails, you can try again, but each repeated attempt costs 1 FP unless you wait five minutes.

The user must take a Concentrate maneuver and make a Will roll to bring up the aura. If he fails, he may try again on later turns, but each successive attempt costs 1 FP. If successful, then the aura is active for the next minute. For a beneficial Affliction, the user may roll Will (as a free action) when someone he wants to bless enters his area of effect. Success means that person is blessed; note the margin of success. On a failure, he may continue to roll once per second (again, as a free action) with no penalty or cost, until successful in blessing that subject. Those blessed stay that way until they leave the area or the aura ends, in which case the effects of the aura linger for seconds equal to the user’s original margin of success for that person.
For a hostile Affliction, the user may attempt to curse anyone entering the area of effect. This works the same as blessings, but is treated as a Quick Contest of the user’s Will versus the target’s HT. The victim suffers the effects for seconds equal to the user’s margin of victory.
The user must make a new Will roll each minute to keep his aura up. If he fails, the aura drops; on any subsequent turn, he may pay 1 FP, take a Concentrate maneuver, and make a Will roll to bring it back up. He may also turn it off voluntarily at the beginning of his turn (as a free action); if so, there is no FP cost to switch it back on.
The adventurer must decide how the aura acts against targets of which he is not aware. He can choose (when buying the ability) whether to affect all unknown targets. Either option is balanced; the decision depends on whether the user would rather risk targeting someone who shouldn’t have been or risk not noticing a potential (but unseen) target until it’s too late.
Deities and other powers above (or below) often grant special abilities to their most dedicated followers, and the capability to instill courage or greatness on their allies just by their presence is a common gift. Auras of Power are specially suited for followers of a deity with a limited portfolio, though omnipotent deities could grant any of them if the GM deems it reasonable.

Sample Aura of Power: Chaos
33 points for level 1, plus 5 points for each additional level

The gods of Chaos can confuse the minds of mortals with horrible visions. The aura covers a two-yard radius around the user. Each additional level doubles that radius, cumulatively. Those cursed by the aura see nightmarish visions overlaying their perceptions, as per Hallucinating (p. B429).
Thus, before each skill roll, those affected must roll against Will. On a success, the victim suffers only -2 to the action, due to disorientation. On a failure, the penalty is increased to -5 and lasts for 1d seconds. On a critical failure, the hallucinations become so real that the victim loses touch with reality for 3d seconds: Roll 1d at the beginning of each of the victim’s turns. On 1-3, he treats foes as friends and friends as foes; on 4-6, the visions are too confusing and the victim just stands still, unable to act or perform active defenses.

Statistics: Affliction 1 (HT; Aura of Power 1, +175%; Hallucinating, +50%) [33]. Higher levels add more Area Effect, at +50% and +5 points per level.

Songs are potent musical abilities, used by supernaturally powered bards to either aid allies or hinder foes. In rules terms, they’re Afflictions with one of these meta-enhancements:

Baneful Song (+105%): Area Effect, 2 yards, +50%; Bard-Song, -30%; Based on Will, +20%; Emanation, -20%; Malediction 1, +100%; Reduced Duration, 1/60, -35%; Selective Area, +20%.

Beneficial Song (+105%): Area Effect, 2 yards, +50%; Bard-Song, -30%; Based on Per, +20%; Emanation, -20%;Malediction 1, +100%; Reduced Duration, 1/60, -35%; Selective Area, +20%.

Songs potentially affect everyone the bard chooses to influence within two yards of him. The Bard-Song limitation comprises the following drawbacks: the bard needs to play or sing for at least a second, there must be mana, the song is hindered by Magic Resistance, and the target has to be able to hear the music.
For Baneful Songs, roll a Quick Contest of Will vs. Will plus Magic Resistance (if any). The bard has -5 in low mana. Foes with Immunity to All Mind Control (zombies, greater demons, etc.) are never affected.
For Beneficial Songs, allies simply roll vs. Per minus any Magic Resistance they have. Low mana gives -5.
The margin of victory or success, respectively, is the number of seconds the Song’s effects last. The bard can play constantly, causing a roll every turn, or cease after a second and hope that the residual effects will suffice.

Sample Baneful Song: Dirge
25 points for level 1, plus 5 points for each additional level

Dirge dooms the bard’s enemies to failure and disaster, usually in combat. Those who fail to resist suffer -3 to ST and DX for the duration, penalizing attack and damage rolls. The song reaches a two-yard radius around the performer. Each additional level doubles that radius, cumulatively.

Statistics: Affliction 1 (Will; Attribute Penalty, -3 ST, -3 DX, +45%; Baneful Song, +105%) [25]. Higher levels add more Area Effect, at +50% and +5 points per level.

Sample Beneficial Song: Alarum
31 points for level 1, plus 5 points for each additional level

Allies affected by Alarum are inspired to strike down foes brutally and with relish. For the duration, they enjoy +2 to ST for the singular purpose of dealing blows. This normally gives +1 to damage with thrusting attacks and +2 to damage with swings.
The song reaches a two-yard radius around the performer. Each additional level doubles that radius, cumulatively.

Statistics: Affliction 1 (Per; Advantage, Striking ST 2, +100%; Beneficial Song, +105%) [31]. Higher levels add more Area Effect, at +50% and +5 points per level.

Storms are powerful elemental abilities, based on Innate Attack, that blast many foes. They work even in good weather or indoors! All have these modifiers:

Elemental Storm (+190%): Accessibility, Requires gesture, -10%; Area Effect, 16 yards, +200%; Bombardment, Skill 14, -5%; Emanation, -20%; Limited Use, 1/day, -40%; Nuisance Effect, Exploitable hole in center, -5%; Overhead, +30%; Persistent, +40%.

In practical terms, once a day, the user may take an Attack maneuver to plant his staff in the ground – or make a similar bold gesture, like smashing his oil lamp – and initiate the Storm. On that turn and on each of his next nine turns (10 seconds total), the Storm blasts everyone (friend or foe) within 16 yards of the spot where he stood. Roll an attack from above at skill 14; victims may block or dodge, but must focus their attention either upward or at ground level, suffering -2 on defenses vs. attacks from the direction ignored. The summoner is safe if he remains at the eye – as is any foe in close combat with him – but if he steps from where he started his Storm, he takes damage. He cannot end the Storm early, dial back damage, etc.

Sample Storm: Air
41 points

Bolts of lightning fry the area from above. Anyone struck takes 2d+1 burning damage. A wounded victim must make a HT roll, at -1 per full 2 HP of injury, or be stunned. He may roll vs. HT each turn to recover, but later bolts can stun him anew.

Advantages: Burning Attack 2d+1 (Elemental Storm, +190%; Side Effect, Stunning, +50%) [41].
