Wondrous item, uncommon
This short brass scope weighs 1 pound. Looking through the scope causes everything to appear extremely colorful. Rotating the barrel of the scope causes a series of twisting visual effects to simultaneously occur and overlap, creating a brilliant display of randomized colors and patterns over top of the viewed scene.
When you peer through the lens at a creature that you can see within 60 feet of you, you can speak the kaleidoscope's command word using an action to force that creature to succeed on a DC 13 Wisdom saving throw. On a failed save, the creature is affected by the hypnotic pattern spell. This version of the spell doesn't require concentration, but it ends early if you can no longer see or if you stop looking at the creature through the scope. Once this property of the scope has been used, it can't be used again until the next dawn.
"Whooooooooooah."
