Boar Style

Combat Style

Your sharp teeth and nails rip your foes open.

Prerequisite: Improved Unarmed Strike, Intimidate 3 ranks.

Benefit: You can deal bludgeoning damage or slashing damage with your unarmed strikes—changing damage type is a free action. While using this style, once per round when you hit a single foe with two or more unarmed strikes, you can tear flesh. When you do, you deal 2d6 bleed damage with the attack.
