Your flowing movement makes it difficult to catch you off guard, and even more difficult to escape your reach.
Benefit: The bonus creatures receive to attack rolls when flanking you is reduced by 1, and you gain a +2 bonus to dodge AC to avoid attack of opportunity from moving through a threatened square (this bonus stacks with the bonus granted by Mobility). Whenever you successfully hit with an attack of opportunity against an opponent with a melee weapon, you can move up to 10 feet in any direction, so long as your movement ends in a space adjacent to that opponent. This movement does not provoke attacks of opportunity from the target you struck, but still provokes as normal from other creatures. Your total movement each round from this feat can’t exceed your normal speed.
