Benefit: Before making a melee attack, you can choose to take 1d6 points of damage. If you hit, you inflict an extra +2d6 points of damage on your foe. You can use this feat once per round, and a number of times per day up to your level.
Incorruptible Soul [General]
You can turn assaults on your mind into assaults on the body.
Prerequisites: 4th level, Iron Will, Con 13+, Cha 13+
