While you are using the Kitsune Style feat, you can apply two different conditions with a single dirty trick combat maneuver check. Removing both conditions imparted in this way requires only one action.

You receive a +2 bonus on checks made to attempt a dirty trick. This bonus stacks with the bonus granted by Improved Dirty Trick. Whenever you successfully perform a dirty trick, the penalty lasts for 1d4 rounds, plus 1 round for every 5 by which your attack exceeds the target’s CMD. In addition, removing the condition requires the target to spend a standard action.

Once per round while raging, the barbarian can attempt a dirty trick combat maneuver in place of a melee attack. This attempt does not provoke attacks of opportunity. If successful, the target takes an amount of damage equal to the barbarian’s Strength modifier and must succeed at a Fortitude save (DC 10 + 1/2 the barbarian’s level + the barbarian’s Strength modifier) or take an additional penalty from the dirty trick based on the type of dirty trick performed and the following table.
Initial Penalty => Additional Penalty
Blinded => Staggered
Dazzled => Dazed
Deafened => Staggered
Entangled => Anchored in place and unable to move from that square
Sickened => Nauseated
On a failed Fortitude save, the opponent takes this additional penalty on top of the dirty trick’s original effect. The additional penalty lasts for 1 round (though the initial penalty lasts as long as normal), and can be removed with a move action. The initial effect cannot be removed via mundane means until the additional penalty is removed (though magical effects like remove blindness/deafness work). Removing the initial effect also removes the additional penalty. If the target is immune to the initial penalty, then it is unaffected by the additional penalty.
This power can only be used once per opponent per rage. A barbarian must be at least 6th level to select this rage power.
