As part of the big reveal for Genshin Impact's Luna I, the gacha game's next big update landing on September 10, the devs at MiHoYo unveiled a new system that will let players boost their characters from the current level cap of 90 all the way up to 100. The catch is that the item that will let you reach the new cap is effectively exclusive to the game's whale-level spenders.
Currently, getting duplicate versions of Genshin Impact characters from gacha pulls will reward you with constellation level upgrades for them, up to a max of constellation level six – or C6, in the fandom's parlance. For the rarest, 5-star characters, you'll soon start to get an item called a Masterless Stella Fortuna for further duplicates after they've reached C6.
