When you reposition foes, they are left vulnerable to the attacks of your allies.
Benefit: You receive a +2 bonus on checks made to reposition a foe. This bonus stacks with the bonus granted by Improved Reposition. Whenever you reposition a foe, his movement provokes attacks of opportunity from all of your allies (but not you).
