Cataclysm

Crimson spears of lighting strike down in an area you can see within range. Each creature in a 40-foot-radius sphere centered on each point you choose must make a Dexterity saving throw. The sphere spreads around corners. A creature takes 20d6 lightning damage and 20d6 piercing damage on a failed save, or half as much damage on a successful one. A creature in the area of more than one strike is affected only once.

The spell damages objects in the area and ignites flammable objects that aren't being worn or carried. The spell is not influenced by metals or lures.
