Your strikes tear into your opponent’s natural defenses.
Benefit: You can make sunder checks against an opponent’s natural armor. You make a sunder check as normal, using a melee weapon. On a successful hit, you deal only half your normal damage to the creature struck, but reduce the creature’s natural armor by 1 (minimum 0). Armor bonus lost in this way can only be restored by a Heal check (DC 10 + your base attack bonus, taking 10 minutes per point of natural armor lost) or by applying a restoration, regenerate, heal, wish, or miracle to the creature (which restores all lost natural armor with no check needed). A creature that has the regeneration ability recovers lost natural armor bonus at a rate of 1 point per round.
