Acidic Strike

You coat your weapon in a layer of corrosive acid.
For the duration of the spell, your unarmed attacks
deal an additional 1d6 acid damage.
In addition, whenever you hit a creature with a unarmed attack,
the acid splashes onto the target and any creature within
5 feet of it, dealing 1d4 acid damage to each creature affected. A successful Dexterity saving throw reduces damage by half.
