Damage Reduction (Ex): Anorith has Damage Reduction equal to half its hit dice. Harden (Ex): If Anorith takes a full defense action, its natural armor bonus improves by 4 points for three rounds. Multiple full defenses do not stack. Metal Claw (Ex): As a Swift action, Anorith may sharpen its claws, making them even more painful. The size category improves by another category and its Constitution modifier is added as extra damage. This lasts for one full round, and in this case means it deals 1d4+2 damage.
