Collapsing Star

A dim light wrapped in shadows floats to the area chosen within range and then blossoms with a low roar into an explosion of darkness and starlight. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 8d6 Psychic damage on a failed save, or half as much damage on a successful one.

The dim light persists to illuminate the affected area for 1 minute. The light also reveals what is hidden.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
