4th-level Spell: Exsanguinate

Sorcery (Necromancy)

You drain a creature of blood, tearing its vital energy away. The target must make a Constitution saving throw. On a failure, its current and maximum hit points are reduced by 6d6. On a success, its current hit points are reduced by half as much, and its maximum hit points are not reduced. If the target was below half its maximum hit points before the spell was cast, its current hit points are reduced by an additional 6d6 hit points, regardless of the save result.
Any maximum hit point reduction caused by this spell lasts until the target finishes a long rest or is targeted with greater restoration. A creature without blood is immune to this spell.

• At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the hit point reduction on a failed saving throw is increased by 1d6 for each level over 4th.
