Rend

Type of Feat: Racial
Prerequisite: Race-Specific.
Specifics: If a creature with this special attack (extraordinary) hits the same target twice in a row during the same round with it's natural attack, it latches onto the opponent's body and tears the flesh. A rend attack deals damage equal to the creature's natural attack + 1-1/2 times its Str modifier.
Use: Automatic.
