Eclipse Burst

A globe of freezing darkness explodes in a 60-foot-radius sphere from a point within range. Each creature in that area must make a Dexterity saving throw, taking 8d10 cold damage plus 8d4 additional necrotic damage on a failed save, or half as much damage on a successful one. Creatures that critically fail the saving throw become blinded by the darkness for an unlimited duration. Objects in the area of the spell automatically fail the saving throw but only take the cold damage.

The darkness created by the spell spreads around corners. A creature with darkvision can't see through this darkness. Non-magical light, as well as light created by spells of 6th level or lower, can't illuminate the area. If the globe's area overlaps with an area of light created by spells of 6th level or lower, the spell that created the light is dispelled.

At Higher Levels. When you cast this spell using a spell slot of 8th level or higher, the cold damage increases by 1d10 and the necrotic damage increased by 1d4.
