Michelangelo's Marvelous Defense

You summon the great Michelangelo's power and touch a willing creature; their body briefly resembles marble in hardness and strength, and when they take damage, it is reduced by 1d6+1. Once damage is reduced in this way, the spell ends.

The spell's protection increases by 1d6 when you reach certain levels: 5th level (2d6), 11th level (3d6), and 17th level (4d6).
