Cauterize

The piece of iron in your hand burns bright red as a ray of fiery energy jumps to a creature of your choice within range. The creature's wounds seal painfully and it regains hit points equal to 2d4 + your spellcasting ability modifier.

The creature must make a Constitution Saving Throw against your spell save DC. On a failed save, the creature has disadvantage on its next attack.

At Higher Levels. When you cast this spell with a spell slot of 2nd level or higher, the healing is increased by 1d4 for every slot level above 1st.
