Mordenkainen's Lost Notebook
8-level Transmutation
You reel as your flesh hardens into solid onyx, and rejoice as your fists crackle with the power of thunder and lightning. You take the form of a marut (MToF). You gain 50 temporary hit points, which disappear at the end of the spell’s duration. You can use the marut’s plane shift ability once, but you don’t gain access to the marut’s legendary resistance or magic resistance.
