Aura of Death

5th-level necromancy

Casting Time: 1 action

Range: Self (60-foot radius)

Components: V, S, M (a small chunk of salt)

Duration: Concentration, up to 10 minutes

Until this spell ends, life-denying energy emanates from you, rendering living creatures within 60 feet of you unable to heal and recover quickly. This spell has no effect on undead and constructs. Other creatures you choose in the area have disadvantage on saving throws against disease, poison, and death. If a creature in the area would regain hit points, it must make a Constitution saving throw. On a failure, the creature regains no hit points. If the saving throw succeeds, the number of hit points regained is instead halved.
