Item Slot: Head 3.400 gold
Power (Daily; Minor): The wearer can Change Shape (see monster manual p280) to alter its physical form to take on the appearance of another creaure of its size or one size category larger or smaller, including a unique individual (giving a +20 bonus on its Bluff check to impersonate that individual).
