Eminence

You summon forth your inner radiance and propel it outwards. Each creature other than you within 15 feet of you must make a Dexterity saving throw. A creature takes 3d6 radiant damage on a failed save or half as much damage on a successful one. In addition, you regain 1d6 hit points.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot above 2nd, and the healing increases by 1d6 for each slot above 2nd.
