Pin Down (Feat)

You easily block enemy escapes.

Prerequisites: Level 11, Combat Reflexes, one of the following: Fighter's Challenge class feature, Goading Ki (Feat), Censuring Smite (Feat) or Heedful Jeer (Feat)

Benefit: Whenever an opponent you threaten takes a 5-foot step or uses the withdraw action, that opponent provokes an attack of opportunity from you. If the attack hits, you deal no damage, but the targeted creature is prevented from making the move action that granted a 5-foot step or the withdraw action and does not move.
