Wave of Putrefaction

6th-Level Necromancy

Casting Time: 1 action
Range: Self (60-foot cone)
Components: V, S, M (a withered bone)
Duration: Instantaneous

You unleash a wave of putrefying necrotic energy in a 60-foot cone. Each creature in the area must make a Constitution saving throw. On a failed save, a creature takes 8d6 necrotic damage and is afflicted with a putrefying disease until cured or until it finishes a long rest. On a successful save, a creature takes half the damage and isn’t afflicted with a disease. A creature afflicted with this disease can’t regain hit points.

This spell induces a magical disease in the target that can’t be cured by most effects that remove or ameliorate diseases. A greater restoration or heal spell cast on the target removes this magical disease.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the damage increases by 1d6 for each slot level above 6th.
