Circle of Death

6th-level necromancy

Casting Time: 1 action
Range: 150 feet
Components: V, S, M (the powder of a crushed black pearl worth at least 500 gp)
Duration: Instantaneous

A sphere of negative energy ripples out in a 60-foot- radius sphere from a point within range. Each creature in that area must make a Constitution saving throw. A target takes 8d6 necrotic 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 7th level or higher, the damage increases by 2d6 for each slot level above 6th.
