Rend (Ex): If a scrag hits with both claw attacks, it latches onto the opponent's body and tears the flesh. This attack automatically deals an additional 2d6+9 points of damage.
Regeneration (Ex): Fire and acid deal normal damage to a scrag. If a scrag loses a limb or body part, the bit portion regrows in 3d6 minutes but only if mostly immersed in water. The creature can reattach the severed member instantly by holding it to the stump.
Scrags have no fear of death: They launch themselves into combat without hesitation, flailing wildly at the closest opponent. Even when confronted with fire, they try to get around the flames and attack.
