Death's web

As you touch the components to the ground a web of black flames shoot out from that point to the targets. Each creature in a 20-foot-radius cylinder centered around yourself must make a Dexterity saving throw. A target takes 6d8 neurotic damage on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 3rd.
