Black Snow

thousands of black orbs surround the caster and then are sent to and area within range. Each creature in a 10-foot-radius sphere centered on that point must make a Constitution saving throw. A creature takes 3d10 necrotic damage on a failed save, or half as much damage on a successful one. A creature that is a cr level 1 or lower has disadvantage on this saving throw.

A nonmagical object that isn’t being worn or carried also takes the damage if it’s in the spell’s area.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d10 for each slot level above 2nd.
