While under the Monstrous Urges Condition, your flesh transforms, becoming chiton, blubbery hide, scales, or some other form of natural armor. When you take this Knack, you may spend up to your Monster rating on tags to determine the effects of your armor. If you take Hard armor, any damage dealt to it heals as if it were your own flesh; if you invoke Chimera Hide again before it has a chance to heal, the damage still remains. This Knack replaces any other form of natural or worn armor as your monstrous hide bursts through anything that might contain it
