Level Transfer Tickets can be used via Inventory > Level Transfer.
Select the card in your inventory that will receive the level, then designate the card from which the level will be transferred on the Level Transfer page to complete the process.
The requirement of receiving levels may vary depending on the card, and you must have the required number of tickets to use them.
For example, if a ★5 card receives the level from a ★10 card, the ★5 card will become ★10, and the original ★10 card will be reset to ★1.
※ Cards that are equipped in a deck cannot be used as materials for Level Transfer Tickets.
