Celeste's Shower of Stars

The sky above the target zone darkens, and tennis-ball sized sized stars rain down in the target area. Each creature in a 30-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 4d8 radiant damage on a failed save, or half as much damage on a successful one.

 It ignites flammable objects in the area that aren't being worn or carried.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 3rd.
