You and your allies have trained together long enough to know how to exploit an opponent's disadvantage to make her predicament even worse.

Prerequisite(s): Combat Expertise, Improved Dirty Trick, Underhanded Teamwork, base attack bonus +6.

Benefit: Whenever an ally who also has this feat performs the dirty trick combat maneuver against a foe that you both threaten, you may attempt a dirty trick combat maneuver against the same foe as an immediate action to inflict a second condition. If the foe uses an action to remove the first condition, it also removes the condition imposed by your immediate action.
