Cauterize

1-level Evocation

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 retains hit points equal to 2d4 + your spellcasting ability modifier.   The creature must make a DC 12 Constitution saving throw, on a failed save, the creature has disadvantage on its next attack.
At higher levels: When you cast this spell using a spell slot of 2nd level or higher, the healing is increased by 1d4 for every level above 1st
