You easily tear your enemies limb from limb with your natural attacks.
You deal rend damage if you hit with half the normal natural attacks your rend requires. For example, a troll that has this feat can rend when it hits with one claw attack, while a girallon that has this feat must hit one target with two claw attacks to rend. You can only make this rend attack once per round.
