Comet Strike

You open several gateways to Limbo a pull thousands of purple shooting stars that plumet to the ground at 12 different points you can see within range. Each creature in a 120-foot-radius sphere centered on each point you choose must make a Dexterity saving throw. The sphere spreads around corners. A creature takes 50d12 Force damage, 50d12 Radiant damage, and 50d12 Necrotic damage on a failed save, or half as much damage on a successful one. This damage ignores immunity and resistance. A creature in the area of more than one chaotic comet is affected only once. Structures and non-magical objects in the area of this spell are decimated and disintegrated.
