Keening Wail

You emit an unholy shriek from beyond the grave. Each creature in a 15-foot cone must make a Constitution saving throw. A creature takes 6d6 necrotic damage on a failed save, or half as much damage on a successful one. If a creature with 50 hit points or fewer fails the saving throw by 5 or more, it is instead reduced to 0 hit points. This wail has no effect on constructs and undead.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d6 for each slot level above 4th.
