Dread Piper of War

On the Orcish highlands, high atop the Dwarven mountain manses, and at the Githyanki outposts deep in the Astral Sea, the discordant moan of the Dread Pipes can be heard. Dread Pipers train for years with ancient masters to learn the secret techniques to use their pipes to strike fear into the hearts of their foes. This training gives the following benefits:

• You gain proficiency in Performance.
• You can use an action to play a wind instrument to emit a short, discordant melody or cacaphonous screech. Each creature within 30 feet of you that hears you play must make a Wisdom saving throw contested by your Intelligence (Performance) check. On a fail, the target becomes frightened of you for 1 minute. If you wish, all creatures in the area that aren't hostile toward you automatically succeed on the saving throw. A creature that fails the saving throw can repeat it at the end of each of its turns, ending the effect on itself on a success. A creature that succeeds on its saving throw is immune to the effect of these pipes for 24 hours.

You can use this feat a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
