Dispelling Fist

By focusing on your knowledge of magic and spells that negate its powers, you use your bare hands to rip magical defenses from your enemy.

Prerequisite: Improved Unarmed Strike, base attack bonus +11, ability to cast dispel magic, caster level 7th.

Benefit: If you have dispel magic prepared or can cast it spontaneously, you can cast it as a swift action after hitting an opponent with an unarmed strike. Treat this as a targeted dispel against the opponent you hit.
