HoYoverse has officially revealed details about Anomaly Arbitration, the newest permanent game mode coming to Honkai: Star Rail. This challenging content will test players' strategic skills when it launches in Version 3.6, expected around late September.

Currently, Honkai: Star Rail features three major endgame modes: Memory of Chaos, Pure Fiction, and Apocalyptic Shadow. The introduction of Anomaly Arbitration marks the first significant addition to this lineup since Apocalyptic Shadow debuted in Version 2.3 back in June 2024.

The new mode will feature a unique structure with three preliminary trial challenges followed by a climactic final stage. Players must assemble three distinct teams for the initial trials, with no character overlap allowed between squads. After completing these battles, participants can freely compose their ultimate team to face the mode's most formidable enemies.

Accessing Anomaly Arbitration won't be easy - players must first conquer the highest difficulty levels of all existing endgame content. Specifically, requirements include clearing Stage 12 of Memory of Chaos, Stage 4 of Pure Fiction, and Apocalyptic Shadow at Difficulty 4 with full stars.

Rewards for this challenging content will include special leveling materials, exclusive avatar frames, cosmetic outfits, and likely Stellar Jades. HoYoverse has promised to share more details about the mode's mechanics and rewards in future announcements.

Alongside Anomaly Arbitration, Version 3.6 will introduce quality-of-life improvements including team-composition guides and a new event preview system. Players can look forward to learning more about upcoming characters Cerydra and Hysilens during the Version 3.5 livestream on August 2.
