A layer of acidic slime coats a babau's skin. Any creature that strikes a babau with a natural attack or unarmed strike takes 1d8 points of acid damage from this slime if it fails a DC 18 Reflex save. A creature that strikes a babau with a melee weapon must make a DC 18 Reflex save or the weapon takes 1d8 points of acid damage; if this damage penetrates the weapon's hardness, the weapon gains the broken condition. Ammunition that strikes a babau is automatically destroyed after it inflicts its damage.
