Elemental Fist

You swirl your hands in a circle in front of you and recite a chant. Choose a type of elemental damage: Acid, Cold, Fire, Lightning, Necrotic, or Radiant. Your hands are imbued with that type of element and glow an according color. Any time you hit with an unarmed strike until the spell ends, you add an extra 1d4+(your spellcasting ability modifier) to each hit.

At Higher Levels. When you cast this spell using a slot of 2nd level or higher, the damage per hit is increased by a d4 for each slot level higher than 1st. For example, using a slot of 3rd level would increase the damage to 3d4+(your spellcasting ability modifier).
