Nullify

From D20advanced

NULLIFY
Type: Trait	Action: One (active)
Range: Ranged	Duration: Instant
Resistance: Will	Cost: 1-3 points per rank

Nullify can counter particular FX, or perhaps even any FX . You can’t nullify innate FX.

Make a ranged attack roll to hit the target. If you overcome the target's Will resistance or the FX’s rank +10 (whichever is higher), you successfully nullify the FX. If you are targeting the subject of an effect rather than the effect’s user, make your check against the FX's rank + 10, not the user's Will. If you win, the targeted FX turns off, although the user can re-activate it normally. If you fail, you do not Nullify the FX and trying again against the same subject increases the target's resistance by +1 per attempt. The cost per rank determines what you can counter:

1 point: Counter any one FX of a particular descriptor at a time (fire FX, magical FX, mental FX, etc.) or a single FX of any descriptor (Mind Control, Snare, Teleport, etc.). Choose the affected descriptor or FX when you acquire the FX.
2 points: Counter all FX of a particular descriptor (such as fire or magic) or type (like attack or sensory FX) at once. Choose the affected descriptor or type when you acquire the FX.
3 points: Counter all FX at once. This level of Nullify is available only with the Gamemaster’s permission and may depend on the nature of FX in the setting.

FX Feats

Affects Insubstantial: Nullify does not require this FX feat to affect insubstantial targets, or the Insubstantial FX itself. You can attempt to nullify the FX of insubstantial targets normally.
Selective: If you can Nullify multiple FX at once, this FX feat allows you to choose which are nullified and which are not.

Extras

Alternate Resistance: Nullify may require a Fortitude rather than a Will save to represent an effect resisted by the subject’s physical fortitude rather than strength of will.
Area: An Area Nullify effect works on all targets in the area. Make a single FX check and compare the result against the opposed FX checks or Will saves of the targets. Targets lacking any FX you can nullify are, naturally, unaffected.
Duration: If Nullify’s duration is increased above instant, any countered FX is suppressed and cannot be re-activated until the duration expires. The user of the countered FX may spend a hero die to gain a Will check to recover use of the ability. If successful, the FX can be re-activated.
Effortless (+1): Trying again does not grant your opponent a bonus to subsequent attempts. You can retry a Nullify attempt an unlimited number of times.
No Resistance: You automatically Nullify FX with a rank equal to or less than your Nullify rank with no opposed check.
Nullifying Field (+0): Rather than targeting a specific individual, you can Nullify FX in a radius of (rank x 5) feet around you as one action. This is a combination of the Touch range (–1) and Burst Area (+1) modifiers. Some characters have a Nullifying Field as an Alternate FX of Nullify. Some Nullifying Fields also have the Duration extra.
Randomize (+0): Rather than being countered, the effect(s) targeted by your Nullify acquire the Uncontrolled flaw and go out of control (as dictated by the GM).
Selective Attack: If you have an Area Nullify effect, this extra allows you to choose who in the area is and is not affected by it, nullifying some targets and not others.
