Astral Burst

A shimmering, otherworldly energy erupts from your hands, expanding outward in a blinding flash. The air crackles with cosmic power as radiant force strikes your foes.

You unleash a burst of cosmic energy from the astral plane. Each creature in a 10-foot radius sphere centered on a point you choose within range must make a Dexterity saving throw. On a failed save, a creature takes 2d8 cosmic damage. On a successful save, the creature takes half as much damage.

The burst also creates blinding light in the area. Creatures within the area of the burst must succeed on a Constitution saving throw or be blinded until the start of your next turn.

Higher Level: When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd.
