Throne of Liberty allows players to change the server they are playing on. While the game is new, this service is completely free of charge. However, in the future, it will cost 750 Lucent, which is roughly equal to $7 USD in 2024. The transfer ticket is valid for 24 hours after purchase, so you have a limited amount of time to use it. If you time the redemption correctly, it may be very well possible that you can use it after the campaign ends.
