At 2nd level, a rageshaper becomes difficult to harm in his devastating form. Whenever the rageshaper takes on his devastating form and is unencumbered and either wearing no armor or wearing light or medium nonmetal armor, he gains a +2 natural armor bonus to his AC and DR 2/—. At 10th level, the rageshaper's DR increases to 5/—. At 15th level, the rageshaper's DR increases to 7/—. At 20th level, the rageshaper's DR increases to 10/—, and his natural armor bonus to AC increases to +4. This replaces defensive instinct, chimeric aspect, and greater chimeric aspect.
