You cause the target that you can see to sprout a second pair arms that make unarmed strikes against it. The target must make a Constitution saving throw.

On a failed save, each arm inflicts 1 + the target's strength modifier for each round during the duration of the spell.

The spell can also be ended by greater restoration, heal, or wish.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the target sprouts an additional pair of arms for each slot level above the 1st, dealing an extra 1 + the target's strength modifier bludgeoning damage per arm.
