Higher than usual Teleport costs?

[Evergrey]

There are a couple ways to reduce the teleportation cost but it will require some time and dedication.
If you haven't, send your Adventurer Squadron to do missions that (if successful) grants Priority Aetheryte Pass - Teleport Fee Reduction: 40% Duration: 120m..
And/or do some old Hunts (ARR, HW & SB / Allied Seal & Centurio Seal) to buy Aetheryte Ticket - A free teleport for each ticket.
