You can increase the Tier of your existing Ships by using Premium Ship Tier Up Tickets. Upon use, the existing Ship and the corresponding Ship Tier Up Ticket will be consumed.

※ Upon use, the target Ship will be transformed and Tiered Up.

※ The Ship Level will remain the same, but the Upgrades and Calypso’s Blessings applied to the Ship will be reflected by taking the cost into account.

※ Premium Ship Tier Up Ticket can be crafted at the Shipyard by collecting Premium Ship Blueprint.
