You have learned techniques to focus the force of an unarmed strike into the most vulnerable parts of a large opponent's anatomy.

Prerequisites: Wis 13, Improved Unarmed Strike.

Benefit: When you make a charge attack against an opponent at least one size category larger than you, your unarmed attacks deal damage as though you were one size category larger. In addition, you gain a +2 bonus to the DC of any Stunning Fist effect you deliver with this charge attack.
