A recent Honkai: Star Rail leak has given details about a new Apocalyptic Shadow boss, which will arrive in version 2.5. Honkai: Star Rail's Apocalyptic Shadow mode is the newest endgame content for players with high-level units. It offers a decent number of Stellar Jades, requiring Trailblazers to defeat more powerful versions of enemies they've faced before. This combat domain is meant to be an all-new challenge for those who can already beat other endgame modes, such as Pure Fiction and Memory of Chaos.
