Exchange Life

A creature you touch regains a number of hit points equal to 1d8 + your spellcasting ability modifier. You also take the same amount of damage that you heal. If your hit points reach zero, you fall unconscious and automatically lose a death saving throw. This spell has no effect on undead or constructs.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the healing and damage increases by 1d8 for each slot level above 1st.
