Maddening Horns

Wondrous item, rare

This brass musical instrument resembles a double horn with such convoluted tubing that the eye cannot follow its path. You can use an action to speak this horn’s command word and then blow the horn, which emits a cacophonous blast in a 30-foot cone that is audible 600 feet away. Each creature in the cone must make a DC 15 Wisdom saving throw. On a failed save, a creature suffers the effects of a confusion spell until it rolls a 9 or 10 on its behavior roll for the spell. On a successful save, a creature is immune to the effects of the maddening horn until it takes a long rest.

Each use of the horn’s magic has a 15% chance of causing you to fall under the effects of the maddening song as well.
