The power flowing through your veins also flows through your unarmed strike.
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.
You can take this feat multiple times. Each time you take it, you apply it to a different qualifying bloodline power.
