Engineer Lekon:
Flying Boat, eh? If you want board a Flying Boat, you need to first register for a Summon License. There's a switch on the Flying Boat controls that proves your qualifications to summon and pilot it. Unless you obtain that license, you won't be allowed to fly.
Only clan lords whose clan is level 5 or higher may earn the license. There is also a limit on the number of Flying Boats.
If you meet the requirements, you can obtain a Flying Boat Summon License in exchange for 10 Energy Star Stones.
An Energy Star Stone can be made by assembling Star Stones found floating in the skies over Gracia. If you think this is too time-consuming, you can also buy them from Officer Tolonis.
Obtain the Flying Boat Summon License.
