Precise

From D20advanced

PRECISE		FX

FX with this feat are especially precise. You can use a Precise FX to perform tasks requiring delicacy and fine control, such as using Precise Ranged Damage to spot-weld or carve your initials, Precise Move Object to type or pick a lock, Precise Environmental Control to match a particular temperature exactly, and so forth. The GM has final say as to what tasks can be performed with a Precise FX and may require an F, skill, or ability check to determine the degree of precision with any given task. A ranged attack FX with the Precise modifier gains the benefits of the Precise Shot feat, which is essentially the same thing.
