The highest outcome of balance is harmony, and the fastest route to harmony is truth, so sometimes it's best to make sure everyone stays on the straight and narrow path.
Wand of Truth
Wand, uncommon (requires attunement by a spellcaster)
This wand of plain silver is tipped with a carving of a balance scale. It has 5 charges. While holding it, you can expend 1 of its charges as an action to cast the zone of truth spell from it, or expend 1 charge as a bonus action when you make a Wisdom (Insight) check to gain advantage on the check.
The wand regains 1d3 expended charges daily at dawn. If you expend the wand’s last charge, roll a d20. On a 1, the wand crumbles into ashes and is destroyed.
