[RPG] What happens when you sunder a natural weapon

Under the sunder rules you can destroy things by dealing them damage by using the combat maneuver rules? If you are having a hard time with attack roles, could you switch to CMB checks. Granted this only works on natural weapons.

Best Answer

Natural attacks are typically immune to sunder

The combat maneuver sunder says, in part, that a creature "can attempt to sunder an item held or worn by [an] opponent." Natural attacks—"attacks made without a weapon"—are typically neither held nor worn, rendering them immune to the combat maneuver sunder.

Were a creature to grab a foe's somehow-severed limb and start beating his foes with that severed limb only to have one of the creature's foes make a sunder attempt against the severed limb, then the GM would determine the severed limb's hardness and hit points. However, until then, targeting natural attacks with the combat maneuver sunder isn't typically a thing unless specific rules state otherwise (q.v. the hydra).
