Chanting and cursing, you put a hex on your enemy as part of your unarmed strike.
Prerequisites
Hex class feature, Improved Unarmed Strike.
Benefit
When you gain this feat, choose one hex that you can use to affect no more than one opponent. If you make a successful unarmed strike against an opponent, in addition to dealing your unarmed strike damage, you can use a swift action to deliver the effects of the chosen hex to that opponent. Doing so does not provoke attacks of opportunity.
Special
You can take this feat multiple times. Each time you take it, you apply it to a different qualifying hex.
