Draining Kiss

You kiss the target, sapping their mental energy, making a melee spell attack, dealing 2d10 + your spellcasting ability modifier in psychic damage and you heal yourself for half as much damage as you dealt if you hit.

 

At higher levels: When you cast this spell using a spell slot of 2nd level or higher,  the damage increases by 1d10 for each slot above the 1st.
