Description

You drain the life force of those around you, turning their limbs heavy and their bones cold. Each creature of your choice within 20 feet of you must make a Constitution saving throw. A target takes 2d8 necrotic damage on a failure, or half as much damage on a success. The caster regains hit points equal to half the total amount of necrotic damage dealt to Small or larger creatures.

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.
