Wave of Corruption

3rd-level necromancy (fiendish)

Casting Time: 1 action
Range: 30 feet
Components: V, S, M (a scrap of rotten meat or plant matter)
Duration: Instantaneous

When you cast this spell, necromantic energy spreads out in a 30-foot radius around you, corrupting what it comes into contact with. Each unattended, nonmagical object within range takes 3d8 necrotic damage. All food and drink in the area, other than what is being carried, is fouled and made unpalatable. Magic consumables, such as potions, have a 50 percent chance of being ruined, but any such item in the possession of a creature gets a Constitution saving throw using the owner’s save bonus to avoid this outcome.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the necrotic damage increases by 1d8 for every two slot levels above 3rd.
