Bagpipes of The Last Dwarf

Forged by the last dwarf in the Darkmane clan, these bagpipes utter a maddening sound to all who can hear them. The wielder is used to the sound and is not affected. These bagpipes hold the essence of the murder of the Darkmane clan.

When successfully played these bagpipes utter a sound that will drive all who hear them insane. The targets must succeed in a constitution saving throw (DC 20) or suffer madness until the end of combat. 

Madness is a condition that causes disadvantage on all rolls.
