These pipes have 3 charges and regain 1d3 expended charges daily at dawn. You can take a Magic action to play them and expend 1 charge to create an eerie, spellbinding tune. Each creature of your choice within 30 feet of you must succeed on a DC 15 Wisdom saving throw or have the Frightened condition for 1 minute. A creature that fails the save repeats it at the end of each of its turns, ending the effect on itself on a success. A creature that succeeds on its save is immune to the effect of these pipes for 24 hours.
