Minor Action      Personal

Requirement: You must be wielding two melee weapons.

Effect: Until the stance ends, when you hit with a melee attack, you can use a free action to make melee basic attack with your off-hand weapon. You can do this once per round, and the off-hand weapon attack takes a -2 penalty to its attack roll.

Update (4/8/2010)
Replace the Effect entry with the following text: “Until the stance ends, when you hit with a melee attack, you can use a free action to make melee basic attack with your off-hand weapon. You can do this once per round, and the off-hand weapon attack takes a –2 penalty to its attack roll.”

Addition (10/14/2009)
On the Effect line at the end of the sentence, add “other than a melee basic attack.”
