Circle of Leeching

A sphere of negative energy ripples out in a 60-foot- radius sphere from a point within range and then pulls back to the focus of the spell. 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. This heals the caster for half of the damage dealt, unless it hits less than 4 creatures which the healing is a quarter of the damage taken. Burning a sorcery point will change who gets healed and therefore preventing them from taking damage from the ability, however no longer heals the sorcerer.

At Higher Levels. When you cast this spell using a spell slot of 8th level or higher, the damage increases by 2d6 for each slot level above 7th.
