If this token is received as treasure, you become cursed. For as long as you are under this curse, you must equip this candlestick in your mainhand melee slot. You may make ranged attacks with other weapons, but any time you perform a melee attack, it must be with this weapon.
This candlestick does not bestow any combat penalties–beyond being a lousy weapon. The wielder still gains any relevant To Hit or Damage modifiers for melee attacks that they would otherwise get.
