Undo Artifice (Sp)
At 11th-level, you gain the ability to reduce a nonliving item to its component parts, essentially erasing the hand of artifice and rendering the item into a pile of raw natural materials. This effect acts as the spell polymorph any object, working on both magical and nonmagical nonliving objects. The duration is always permanent. Unlike polymorph any object, it cannot be used to mimic the effects of other spells. Items subject to this effect receive a Fortitude saving throw to negate the effect. Magic items receive a circumstance bonus on this save equal to +1 for every 5,000 gp in the item’s value. You may use undo artifice a number of times per day equal to your Charisma modifier.
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 surround yourself with an organic cocoon as a full-round action. While enclosed in the cocoon, you are considered helpless. Eight hours later, you emerge having changed your type to plant, animal, or humanoid, gaining superficial physical characteristics as appropriate (see the Pathfinder RPG Bestiary). 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.
