Energy Blast

You create a blast of healing or damaging energy that emerges from your hand in a 80ft cone. If you choose damaging, every creature within the cone has to make a Dexterity saving throw or take 10d10 necrotic, radiant, cold, fire, lightning, thunder, force, poison, psychic, or acid damage. If you choose healing, every friendly creature in the cone regains 10d10 hit points.

At higher levels: if you cast this spell using a spell slot of 8th level or higher, the damage and hit points regained increase by 2d10
