Level: Sorcerer 8, Wizard 8
Components: V, S
Casting Time: 1 swift action
Range: Personal
Target: You
Your flesh turns into solid onyx, and your muscled fists crackle with the unbridled power of thunder and lightning.
You take the form of a marut, including the full plate armor normally worn by such a creature. You gain 50 temporary hit points, which disappear at the end of the spell’s duration. You can use each of the marut’s at-will spell-like abilities (such as dimension door) once per casting of the spell, but you don’t gain access to any of the marut’s 1/day or 1/week spell-like abilities (such as chain lightning or earthquake). See the Polymorph Subschool for more details.
