Decaying Touch

Make a melee spell attack against a creature you can reach. On a hit, the target takes 3d8 necrotic damage.

Additionally, the creature must make a Constitution saving throw against your spell save DC. If it fails , it takes damage from any healing it receives until the end of your next turn. 

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