Sweeping Stance

You enter a stance in which you spin your weapon around in a circular motion and lash out against any enemy that approaches. When an enemy enters your weapon’s range you may make an Attack of Opportunity against them. An enemy moving while already being in your attack range does not provoke. Your weapon's range for these attacks of opportunities is increased by 5ft (This does not affect your normal threaten range).

The stance lasts until you make an attack that isn’t an Attack of Opportunity.
