Catastrophe

A seething vortex of chaotic energy erupts from you, unleashing a variety of destructive forces in a 500‑foot radius. Each creature in the area must make a Dexterity saving throw. On a failed save, a creature takes 15d8 damage; on a successful save, it takes half damage. However, the damage isn’t of one type—roll (or choose) one or more from the following damage types, or have the DM determine the mix (for example, rolling on a table to decide among fire, lightning, acid, thunder, cold, necrotic, radiant, or poison damage):
