You touch a living creature to forcefully transfer vitality. The target must make a Constitution saving throw. On a failed save, the creature takes 2d6 + your spellcasting ability modifier necrotic damage, and you regain hit points equal to half the damage dealt. On a successful save, the creature takes half damage and you regain no hit points.
Alternatively, when you cast this spell, you can choose to target a willing creature and take 2d6 + your spellcasting ability modifier necrotic damage yourself to restore that amount to the touched creature. This self-inflicted damage can’t be reduced or avoided in any way.
This spell has no effect on constructs or undead.
At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st.
