The Torch of Truth appears to be a normal torch that shows obvious signs of previous usage.  When lit, the Torch of Truth will burn with a steady light until extinguished providing bright light in a 20-foot radius and dim light for an additional 20 feet. If you make a melee attack with a burning torch and hit, it deals 1 fire damage.

The Torch of Truth has 3 charges regaining 1d2 charges at dawn each day.  When lit, the wielder can expend one charge to cast Zone of Truth (CHA save DC 15) on the torch itself.  The Zone of Truth will move with the torch for the full 10 minute duration.
