The guide for Lunar Diplomacy stated that you should keep at least one Dramen staff if using the Fairy Rings because the Lunar Staffs can't be used for teleporting until after the quest, but as soon as you hand the character a finished (completed) Lunar Staff, any other completed Lunar Staffs you hold in your bank are usable and since I believe you cannot make any Lunar Staffs after the quest is complete (indeed, perhaps even after that portion of the quest is complete), I think it's a good idea to upgrade any and all Dramen staffs to Lunar Staffs during the quest. It should still be noted that the Lunar Staff isn't usable (and the character keeps the staff until you hand her all the lunar equipment), but that once handed to her, all other staves in your bank can be used for the FRTN (Fairy Ring Teleport Network).
