You can grapple enemies effortlessly with your natural weapons.
Prerequisites: Str 19, Dex 15, improved grab, Multigrab.
Benefit: When grappling an opponent with only the part of your body that made the attack, you take no penalty on grapple checks to maintain the hold.
Normal: Without this feat, you take a −20 penalty (or a −10 penalty with Multigrab) on grapple checks to maintain a hold with only the part of your body used to make the attack.
