You can adopt a strange, erratic fighting style which confuses your opponents.
Benefit: As a move action you can enter into an erratic fighting style which reduces your speed by 10 feet and gives you a -2 penalty to Armor Class, but causes your opponents to lose their Dexterity bonus to Armor Class against your attacks. You can continue to use this ability as a swift action each round once you have started, and you can use it for a number of rounds per day equal to twice your duelist level. The rounds need not be consecutive. In addition, while using this ability, you can use your Perform (dance) skill in place of an attack roll once per round when you attempt to parry an attack.
