Circle of Death

A sphere of negative energy ripples outward in a 60-foot radius from a point you choose within range of the spell. Every creature in the area must make a Constitution saving throw. On a failure, an affected creature takes 8d6 necrotic damage, or half as much on a success.

At Higher Levels. When you cast this spell by spending Mana points equal to a 7th-level spell or higher, the damage increases by 2d6 for each level above 6th.
