You must be proficient with wind instruments to use these pipes. They have 3 charges. You can use these charges to perform one of two effects.
Ear-Splitting Patriotism. (Costs one charge) You may use an action to send a wave of energy rolling across the battlefield. Each creature you designate within 30ft. that can hear the pipes must make on a DC 13 constitution saving throw or take 4d6 thunder damage and become deafened as the sound of a male voice screaming SCOTLAND FOREVER emanates from the pipes.
Scotland The Brave. (Costs one charge) You may use an action to embolden your allies with song. Each creature you designate within 90ft. that can hear the pipes gains immunity to the frightened and charmed conditions and has advantage on all saving throws for an hour as a beautiful song that encourages valor in the name of Scotland plays from the pipe.
The bagpipes regain all expended charges at dawn
