The passport is another way to experiment Luma. By visiting a partner game shop or a game event, you can get your own passport to Luma.
Once you have it, do not forget to check it in via the page "Log in". This passport must be with you everywhere you go. Hopefully, it goes perfectly in your wallet.
Show it each time you visit a border-post (game retailer or game event) and collect the stamps. These stamps will give you Lums on your online account, the key to get promos.
Feel free to browse through the opposite map to find the locations and the events, where you can get your passports and new stamps!
