Boots of dancing
From Ardrana
Boots of dancing expand or contract to fit any foot size, from halfling to giant (just as other magical boots do), and until actual melee combat is engaged in they function like one of the other types of useful magical boots.
When the wearer is in (or fleeing from) melee combat, the boots of dancing impede movement, making the wearer behave as if Otto's Irresistible Dance had been cast upon him. Only a remove curse spell will enable the boots to be removed once their true nature is revealed.
Note: This item originally appeared in this form in the 2nd Edition Dungeon Master Guide for the Advanced Dungeons & Dragons game by TSR. Their inclusion here is for the purposes of providing context for the campaign only.
