Your unarmed strikes are particularly damaging to chaotic creatures.
Prerequisite: Wis 19, Improved Unarmed Strike, Stunning Fist, any lawful alignment
Benefit: Your unarmed strike is treated as a lawful weapon (it deals +2d6 points of damage against creatures of chaotic alignment). This ability doesn't stack with similar abilities (for instance, if some other effect has granted the lawful ability to your unarmed strike).
