With a mighty roar, a foul mist escapes your mouth and is sent out in a 50 ft. cone. Each creature within the cone must make a Constitution saving throw, taking 8d10 necrotic damage on a failure or half as much on a success.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the spells damage increases by 1d10 for each spell slot above 5th.
