You transform the limb of a willing creature you touch into a crushing, hammerlike sauropod foot. For the duration, the affected creature can roll 2d10 in place of its normal unarmed strike damage die. Whenever they make an unarmed strike, they can choose to use your spell attack modifier instead of their normal attack bonus. For the duration, the affected creature also has disadvantage on Dexterity checks.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage of the unarmed strikes increases by 1d10 for every two levels above 4th.
