You fall into a stance that empowers your ability to use special maneuvers in combat.
Prerequisites
Strength 15, Dexterity 15, Combat Expertise, Power Attack, base attack bonus +3.
Benefit
While using this style, you may perform any combat maneuver without provoking an attack of opportunity, and if you make two or more successful attacks with a natural or manufactured weapon, you may expend one attack of opportunity for the round to perform a combat maneuver against any creature you successfully hit this round.
Normal
Any combat maneuver attempted without the relevant “improved” feat provokes an attack of opportunity.
