Death Siphon

5th-level Necromancy

Casting Time: 1 action

Range: Self (20-foot radius)

Components: V, S

Duration: Instantaneous

An aura of necromantic energy spreads like a shadow beneath your feet, stealing life from others to heal your wounds. Each creature in a 20-foot radius must make a Constitution saving throw. A target takes 4d6 necrotic damage on a failed save, or half as much damage on a successful one. You regain hit points equal to half the amount of necrotic damage dealt.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 2d6 for each slot level above 5th.
