Disfigure Limb

The target must make a DC17 Constitution saving throw. If they fail, the target's limb of your choice is unnaturally contorted for 4 turns and becomes unusable. Regardless of the result of the Constitution saving throw, any object held in the limb falls to the ground on cast.

At higher levels: For each additional level past level 3 that this spell is cast at, the spell lasts an additional round.
