Visions Of The Far Realm

You reach into the mind of up to 3 creatures within range, creating a Vision of the Far Realm.  Aberrations are unaffected. All other creatures must make a Wisdom saving throw taking 8d6 psychic damage on a failed save or half as much on a successful one.  In addition, on a failed save the creatures are stunned.  At the end of each of their turns,  affected creatures can make a Wisdom saving throw.  It they succeed, this effect ends for that target.

Finally, if a victim takes any damage, they get another saving throw to end the spell for them.

At higher levels:  When you cast this spell using a spell slot of 5th level or higher, you can target one additional victim for each slot level above 4th.
