The Repeat Quest Permission allows a player to redo a Quest of their choice. If you use this Item it will be deleted and the selected Quest will be displayed in the active directory again. It must be in your Inventory to use. You can also use it to lower the Party Dungeon and Cathedral cool down timers.
They are dropped by many monsters.
Completing a Quest gives experience, MOS or coins randomly. Repeating a quest will give a NEW random bonus.
