View source for Dirty Trick (Combat Maneuver)

==Dirty Trick==
'''Type of Action:''' Standard action

*A Dirty Trick may only be attempted against an adjacent creature. If you have a reach weapon or any other method of extending your combat reach, this does not extend the range of Dirty Trick.

* This maneuver covers any sort of situational attack that imposes a penalty on a foe for a short period of time. Examples include kicking sand into an opponent's face to blind him for 1 round, pulling down an enemy's pants to halve his speed, or hitting a foe in a sensitive spot to make him sickened for a round. 

* The GM is the arbiter of what can be accomplished with this maneuver, but it cannot be used to impose a permanent penalty, and the results can be undone if the target spends a move action (unless a feat makes that into a standard action). 

* If you do not have the Improved Dirty Trick feat or a similar ability, attempting a dirty trick provokes an attack of opportunity from the target of your maneuver.   If that attack of opportunity hits, you take damage as normal, but otherwise suffer no penalty on your Maneuver Offense for the dirty trick attempt.

* If your combat maneuver attack is successful, the target takes a penalty. The penalty is limited to one of the following conditions:

:*[[blind]]
:*[[dazzled]]
:*[[deafened]]
:*[[entangled]]
:*[[shaken]]
:*[[sickened]]

* The condition inflicted by Dirty Trick maneuvers lasts for 1 round. For every 5 by which your attack exceeds your opponent's Maneuver Defense, the penalty lasts 1 additional round. This penalty can usually be removed if the target spends a move action. 

* If you possess the Greater Dirty Trick feat, the penalty lasts for 1d4 rounds, plus 1 round for every 5 by which your attack exceeds your opponent's Maneuver Defense. Alternatively, the target may spend a standard action to end the condition sooner.
