Entrancing Mirrors

You create dozens of illusory mirrors to confuse up to three creatures of your choice that you can see within range. Each target makes an Intelligence saving throw. On a failed save, a target takes 7d6 Psychic damage and has the Stunned condition. While the target is Stunned, its Speed is halved. On a successful save, a target takes half as much damage only. A Stunned target repeats the Intelligence saving throw at the end of each of its turns, ending the spell on itself on a success.
