You devastate enemies that you catch off-guard.
Benefit(s): While you are using Cloak and Dagger Style and wielding your chosen weapon, whenever you hit an opponent that is denied its Dexterity bonus to AC or that you are flanking, or make an attack using Vital Strike (or its improved or greater versions), you can attempt a dirty trick combat maneuver check against that opponent as a free action. If you succeed, the target must succeed at a Fortitude save (DC = 10 + 1/2 your base attack bonus + your Intelligence modifier) or take an additional penalty from the dirty trick selected from the following list: anchored in place and unable to move from that square, confused, exhausted, or staggered. This additional penalty lasts only 1 round, regardless of how long the dirty trick’s normal penalty lasts, and can be removed by the target with a standard action. You can only attempt one free dirty trick combat maneuver check per round using this feat.
