Meteor Swarm
Blazing orbs of fire plummet to the ground at four different points you can see within range. Each creature in a 40-foot-radius Sphere centered on each of those points makes a Dexterity saving throw. A creature takes 20d6 Fire damage and 20d6 Bludgeoning damage on a failed save or half as much damage on a successful one. A creature in the area of more than one fiery Sphere is affected only once.
A nonmagical object that isn't being worn or carried also takes the damage if it's in the spell's area, and the object starts burning if it's flammable.
Meteor Swarm 5e 2024 vs. 2014 edition differences
The 2024 version clarifies that each creature makes a Dexterity saving throw per sphere, and explicitly states nonmagical objects in the area take damage and may start burning if flammable. The damage wording is more precise but mechanically similar; no significant damage or effect changes.
