Consuming Mist

A small, black orb shoots at a constant speed from your finger to a point you choose within range, and then blossoms into an explosion of black mist. Each creature in a 20-foot-radius sphere centered on that point must make a Constitution saving throw. A target takes 6d6 necrotic damage on a failed save, or half as much damage on a successful one. Any creature affected by this spell has their lungs fill up with black mist, preventing speech for 1 round.

The mist spreads through cracks and around corners. It snuffs all magical and non-magical flames in its radius. The mist causes plants to wither and wilt rapidly.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
