Wondrous Item, very rare
Once per day, you may use the Bagpipes of Hilarity to cast Hideous Laughter that affects all creatures within 60 feet.
All creatures within 60ft perceive everything as hilariously funny and fall into fits of laughter if this spell affects it. The target must succeed on a Wisdom saving throw or fall prone, becoming incapacitated and unable to stand up for the duration. A creature with an Intelligence score of 4 or less isn't affected.
At the end of each of its turns, and each time it takes damage, the target can make another Wisdom saving throw. The target has advantage on the saving throw if it's triggered by damage. On a success, the spell ends.
Notes: Debuff
