Greater Disarm
You can knock weapons far from an enemy’s grasp.
Prerequisite: Combat Expertise, Improved Disarm, base attack bonus +6, Int 13.
Benefit: You receive a +2 bonus on checks made to disarm a foe. This bonus stacks with the bonus granted by Improved Disarm. Whenever you successfully disarm an opponent, the weapon lands 15 feet away from its previous wielder, in a random direction.
Normal: Disarmed weapons and gear land at the feet of the disarmed creature.
