Celestial Star Cycle

You summon six small stars that hover in the air and orbit you for the duration of the spell. When you cast the spell — and as a bonus action on each of your turns thereafter — you may use one or two of the stars, directing them to speed at a point(s) you choose within 120 feet of you. Once a star reaches its target or impacts against a solid area, that star detonates. Each creature within 5 feet of the point where the star explodes must make a Dexterity saving throw. A creature takes 2d6 radiant damage on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the number of stars created increases by two for each slot level above 3rd.
