Cataclysm

A massive, blazing comet plummets to the ground at a point you can see within range. You must be outdoors when you cast this spell, or the spell fails. The comet creates a 50-foot-deep, 500-foot-radius crater on impact.  Any creature within that area must make a DC 20 Dexterity saving throw, taking 30d10 force damage on a failed saving throw, or half as much damage on a successful one.

All structures in the crater are destroyed, as are all nonmagical objects that aren’t being worn or held.
