Death Whistle

Wondrous item, uncommon

This item has three charges. You can use an action and expend a charge to emit a horrific sound resembling hundreds of terrified voices screaming in unison in a 20-foot cone that is audible 400 feet away. Each humanoid in the cone must succeed on a DC 12 Wisdom saving throw or take 2d6 psychic damage and become frightened for one minute. On a successful Wisdom saving throw, the creature takes half as much damage, is not frightened, and becomes immune to the effects of this death whistle for 24 hours. Deafened creatures and creatures immune to being frightened take no psychic damage and are not frightened. A creature that fails its Wisdom saving throw can repeat it at the end of each of its turns, ending the effect on itself on a success. The death whistle regains 1d3 expended charges daily at dawn.
