Dark Healing

You utter a divine word, and black mist swirls around your foes while gentle light embraces your allies. Each enemy of your choice that you can see within 30 feet must make a Constitution saving throw. On a failed save, a creature takes 1d6 necrotic damage. Roll the damage once; each affected creature takes that amount of damage. The same roll becomes a pool of healing that you may divide among any number of allies you can see within range. A creature regains the assigned hit points, and one creature healed by this spell may also add its Constitution modifier to the hit points regained.

The spell's damage and healing pool increase to 2d6 at 5th level, 3d6 at 11th level, and 4d6 at 17th level.
