When casting this spell, you touch a non-magical inanimate object. Upon completion, your body takes on some of the traits of the object (such as coloration and texture), and you gain natural armor equal to +1 for every 3 points of hardness the object has (rounded down). While the spell is in effect, the focus object's hardness is reduced to 0 (its hit points and structure remain unchanged, but it is now useless as a weapon or armor).

Focus: The object touched, which must weigh at least 5 pounds.
