See also: Feats, Grappling 101

You are skilled at immobilizing Grappled foes.

Prerequisite: Base Attack Bonus +1

Effect: If you succeed on a Grappling attack and your opponent fails the opposed Grapple check, your opponent is automatically Pinned until the start of your next turn. A Pinned creature can't move or take any Actions while Pinned, and it loses its Dexterity bonus (If any) to Reflex Defense.

Special: You cannot use the Pin and Trip Feats during the same round. You can use the Pin and Crush Feats in the same round, however.
