Surge of Decay

A surge of necrotic energy sweeps out from you. Each creature in a 10-ft sphere originating from you must make a Constitution saving throw. On a failed save, a creature takes 1d8 + your spellcasting modifier necrotic damage. A creature takes half as much damage on a successful save. A creature can willingly fail the save.

This spell has no effect on constructs. This spell heals undead creatures as long as there is some sort of living thing damaged by the spell. This includes plant and animal life.

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.
