Passing Trick
Combat
Slipping past a foe gives you the chance to feint.
Prerequisite: Int 13, Combat Expertise, Dodge, Improved Feint, Mobility, size Small or smaller.
Benefit: Whenever you make a successful Acrobatics check to move through an opponent’s space, you can spend a swift action to make a Bluff check against that opponent to feint in combat.
Special: If you have the Underfoot feat and the opponent is larger than you, you gain a +2 bonus on the Bluff check this feat allows.
