Sorcerous Strike

Combat

The power flowing through your veins also flows through your unarmed strike.

Prerequisite: Sorcerer bloodline class feature, Improved Unarmed Strike.

Benefit: When you gain this feat, you choose one bloodline power that you can use to affect a single opponent. If you make a successful unarmed strike against an opponent, in addition to dealing your unarmed strike damage, you can spend a swift action to deliver the effects of the chosen bloodline power to that opponent. Doing so provokes no attacks of opportunity.

Special: You can take this feat multiple times. Each time you take it, you apply it to a different qualifying bloodline power.
