GURPSよろず

Cosmic is one of the broadest enhancements in GURPS, and arguably the most abusable. After all, the whole point of Cosmic is to let its underlying advantage break the rules! For this reason, even in a campaign where the GM allows players to build their own powers freely, the Cosmic enhancement always requires GM approval on a case-by-case basis.
Still, Cosmic has limits.

• Cosmic cannot alter the fundamental nature of an advantage. No version of Cosmic will let you use Mind Reading to project your thoughts or Invisibility to walk through walls. For this, buy the various advantages you wish to emulate as alternative abilities (see Powers).
• Cosmic cannot change the intended subject of an advantage. You cannot add Cosmic to Metabolism Control and use it to put your enemies in a coma. To use a self-only advantage on others, see Affects Others (p. 12) and Affliction (p. B35).
• Cosmic cannot remove a target’s resistance roll. It can overcome active defenses and advantages which aid resistance (e.g., DR, Mind Shield, and Resistant), but if the victim gets a Contest or unopposed roll to avoid an advantage’s effect, Cosmic cannot take it away. To better overcome your target’s resistance in a Quick Contest, raise your own activation roll using Reliable (p. 16), or a power Talent or power skill (see Powers) – and consider Cosmic, No Rule of 16 (p. 7). Alternatively, if you’re using Affliction, simply raise its level; the higher your level, the worse your subject’s roll, and the Rule of 16 is unlikely to be an issue!
• Cosmic offense cannot overcome Cosmic defense. Some versions of Cosmic allow the advantage to ignore non-Cosmic defenses against it. When such an offense comes up against Cosmic defense, however, handle it as if neither side had Cosmic; the defense protects normally. The “one-upmanship” stops here; e.g., you cannot make an attack that ignores Cosmic DR. To overcome Cosmic DR, buy an attack that does more damage – even Cosmic DR has a finite amount of protection.

Cosmic options are cumulative. For instance, an Innate Attack that requires no roll to hit (+100%), allows no active defense (+300%), and ignores DR (+300%) is +700%. An Attack maneuver lets you immediately apply your damage roll to your target’s HP! Because of the effect this can have on game balance, even if the GM allows Cosmic to be used freely, he may wish to disallow certain combinations of Cosmic.
On a carrier attack, all forms of Cosmic raise the cost of Follow-Up on the follow-up attack.

COSMIC LEVELS
There are three established levels of Cosmic, each with several preexisting examples. This doesn’t mean the GM can’t add more! Use the guidelines below to determine what the cost of a new Cosmic enhancement should be.
All “flavors” of Cosmic can be found below, with the exception of Cosmic as a power modifier. Power modifiers are beyond the scope of this book; see Powers for details.
See p. 12 for an explanation of the

Adding Utility (+50%)
The lowest level of Cosmic is generally used for either removing an inherent restriction or countering a higher level of Cosmic. These improvements are limited in scope and should still feel “fair.” For example, this level of Cosmic could allow an Innate Attack to emanate from any point on the user’s body (e.g., eyes, hands, shoulder – making it impossible for enemies to negate its use by binding his hands, blindfolding him, and so on), but could not make the attack hit automatically or bypass defenses.

Cheating (+100%)
These variants of Cosmic break the rules in a significant, noticeable way. Instead of just removing inherent restrictions, they can ignore or overrule something important to game balance. Cosmic applications at this level are less concerned with fairness, but still cannot casually overwhelm a target’s defenses.

Godlike Tricks (+300%)
At this level, Cosmic doesn’t just allow cheating, it lets the ability do something completely unfair: ignoring a target’s defenses, affecting subjects it should not be able to, and so on. New forms of Cosmic, at this level, can have powerful and far-reaching effects on the underlying advantage – but still subject to the limits described under the introduction to Cosmic (p. 6).

Anything In-Between
When coming up with new forms of Cosmic, the GM is not limited to just these three levels! If a new ability seems too powerful for +100%, but not quite up to the +300% level, don’t hesitate to call it +200%. Removing two unrelated restrictions on an ability is normally a net +100% (two separate +50% Cosmic enhancements) – but if the GM feels that doing so makes the ability too potent, he’s free to call that a new +150% Cosmic. Because Cosmic is so wide-ranging in its applicability, pricing it can often be as much an art as a science.
