Cauterize

You reach out to a creature and burn away any impurities. If a creature is unwilling you must make a melee spell attack. an affected creature takes 2d4 fire damage, and then regains 5d4 hit points at the end of its next turn. if a creature is resistant or immune to fire damage the healing is halved or negated, respectively. A creature reduced to 0 hit points by the fire damage receives no healing from this spell

At Higher Levels. If this spell is cast using a spell slot of 2nd level or higher, both the fire damage and the healing increases by 1d4 for each spell level above 1st.
