A new Honkai: Star Rail leak has revealed that the upcoming update 3.0 might introduce some significant changes to the game's banner system. Like many other HoYoverse games, Honkai: Star Rail runs on a gacha system that allows players to acquire new playable characters by wishing on the limited banner. The game's limited double banners usually include two five-star characters, one new addition to the roster and one re-run unit.
