Cauterize

The metal in your hands burns hot as transmutation magic burns the wounds shut of a creature you touch. The target regains hit points equal to 4d6 plus your spellcasting ability modifier. The target must then make a DC 12 Constitution saving throw. On a failed save the creature has disadvantage on attacks until your next turn.

At Higher Levels When you cast this spell at 3rd level or higher, the healing is increased by 1d6 for every level above 2nd.
