Horn of Silent Alarm

A Horn of Silent Alarm is a magic horn that only one creature can hear at a time.

Description
The horn has four charges. A creature can expend one charge to blow the horn as an action, targeting one creature within 600 feet. Only that creature can hear the horn, provided they aren't deafened. The horn regains 1d4 charges daily at dawn.

History
An individual sold several items to Marwa Endalia, including a Horn of Silent Alarm. Shortly afterwards, she sold the horn to Orym for 30 gold pieces. The next day, he passed the horn to Chetney; as Chetney serves as the frequent scout of the team, Orym thought he would make the most of it.

Chetney used the horn for the first time while trying to warn a member of a caravan in the Hellcatch Valley of an approaching dusttra, but it did not appear to work then. He used the horn more successfully in the Feywild to briefly misdirect Gloamglut and its rider Zathuda; he made it sound as if the noise was coming from a specific direction and tricked them into believing the party was moving in a different direction.
