Final Revelation

At 20th level, you have discovered the intrinsic secrets of life itself, granting you incredible control over your own body. Once per day, you can change your type to plant, animal, or humanoid, gaining superficial physical characteristics as appropriate, as a full-round action. This change does not alter your Hit Dice, hit points, saving throws, skill points, class skills, or proficiencies. Each time the transformation is made, you are cleansed of all poisons or diseases, are restored to full hit points, and heal all ability damage. You must select a new type every time the transformation is made.
