Crimson Harvest

A wave of blood sweeps out from you and crashes into your enemies. Each creature of your choice within 15 feet of you must make a Dexterity saving throw, taking 3d10 necrotic damage on a failed save, or half as much on a successful one. If you damage at least one creature that is size Small or larger, you and a number of creatures within the spell’s range up to your spellcasting ability modifier that you choose regain a number of hit points equal to half the damage roll.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d10 for each slot level above 3rd.
