Elemental Gaunlets

 Spectral gauntlets appear around your hands, crackling with a power of your choice from the following list: Fire, cold, lightning, acid. When attacking with unarmed strikes, the normal damage you would deal is replaced with 2d6 of the damage type of your choice, of course adding only your to hit modifier.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for every other slot level above 2nd.
