Feint Partner

Combat Teamwork

A little diversion is all you need to slip through your foe’s defenses.

Prerequisite: Bluff 1 rank.

Benefit: Whenever an ally who also has this feat successfully feints an opponent, that opponent also loses his Dexterity bonus to AC against the next attack you ® ™ make against him before the end of the feinting ally’s next turn.
