Shared Nightmare

4th-Level Conjuration

Casting Time: 1 action
Range: 60 feet
Components: V, S, M (a pinch of powdered onyx)
Duration: Concentration, up to 1 minute

You cause the minds of up to three creatures you can see within range to share a nightmarish vision. Each target must make a Wisdom saving throw. On a failed save, a target takes 3d6 psychic damage and is haunted by the nightmare for the duration. On a successful save, a target takes half the damage and isn’t haunted.

Until the spell ends, a creature haunted by the nightmare takes 1d6 psychic damage at the start of each of its turns for each other creature haunted by this spell’s nightmare. A haunted creature can make another Wisdom saving throw at the end of each of its turns. On a success, the spell ends on the target.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, you can target one additional creature for each slot level above 2nd.
