In a demonic booming voice you call forth a roaring vortex of fiendish distorted spirits. These tortured spirits of the dead whip around the affected area for the spell's duration. The spirits are ghostly white, intangible, and invulnerable. The affected area is a vortex-like cylinder 15' radius and 40' tall.

Creatures within the affected area must make a Wisdom saving throw. On a failed save, the swiping spirits inflict 3d8 necrotic damage and cause the creature to become frightened of you until the end of their next turn. On a successful save, the creature takes half as much damage and is not frightened.

Until the spell ends, the affected area remains in place. Any creatures who move into or end their turn within the area must make a Wisdom saving throw and are subject to its effects.

The material component* of the spell is consumed in the process.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for every spell slot level above 3rd.
