Dancing Reed Flute

Wondrous item, rare (requires attunement by a creature proficient in Performance)

You may sound a trilling tune on a dancing reed flute as an action to lure a single creature within 30 feet into a whirling, pirouetting balletic dance. The target must make a DC 15 Wisdom saving throw or spend each of its rounds dancing; the creature’s speed is halved and each time it leaves its square, the creature moves in a random direction (roll 1d8 to determine into which adjacent square it moves; it may move back and forth between two squares).

The creature does not move into squares occupied by creatures or solid barriers, nor into obviously dangerous squares such as a wall of fire or off a cliff, but its movement provokes opportunity attacks from enemies threatening a square it leaves. While the creature is dancing, attacks against it gain advantage. The target dances as long as it can hear the flute’s music. If you stop playing or you are affected by magical silence or if the target becomes deafened, the effect ends.

The flute has 3 charges. Each use of the flute expends 1 charge. The flute regains 1d3 expended charges daily at dawn.
