Every Honkai Star Rail patch swaps out the enemy rosters in its four rotating endgame modes, and version 4.4 will be no different. Anomaly Arbitration, Pure Fiction, Memory of Chaos, and Apocalyptic Shadow are all due to refresh when the update goes live, which means new bosses, new mob waves, and new team-building puzzles to solve. The catch is that, for now, the 4.4 versions of those rotations have not been locked in.
Honkai Star Rail 4.4 release window and what's confirmed
Version 4.4 is expected to roll out on August 5, 2026. The character side of the patch is much further along than the endgame side. Himeko SP is shaping up to be the headline unit, and her drip marketing already went out on May 19, 2026, which lines up with how the developers typically reveal new characters about a week into a patch's second half.
The other big talking point is a possible second Fate collaboration featuring Gilgamesh and Rin Tohsaka. Early path and element assignments point to Gilgamesh as a Lightning Destruction unit and Rin as a Quantum Erudition unit, with chatter about one of the collab characters being offered for free. None of that is official yet, and collab timing in particular has shifted before, so treat it as a strong rumor rather than a guarantee.
What matters for endgame players is the cadence. The four rotating modes reset on the patch schedule, so a 4.4 launch in early August means fresh lineups arriving alongside it. Until the beta data lands, the enemy rosters themselves remain open.
The four endgame modes and how their lineups refresh
Each mode tests a different team-building skill, and each cycles its enemies on the patch schedule. Knowing how they're built helps you plan investment before the 4.4 rosters appear.
Anomaly Arbitration runs a set of staged encounters that close with a tougher "King in Check" fight. It tends to reward damage-over-time and debuff-heavy teams that can stack effects across the board.
Pure Fiction spans four stages, but only the final stage really pressures your roster. It throws dense mob waves at you, so area-of-effect damage and fast wave clears matter most.
Memory of Chaos has the most stages of any mode, yet the difficulty spikes in the last two. Stage 12 is the real wall, and it usually splits into two nodes that each demand a built team.
Apocalyptic Shadow is the boss-rush mode. It shares the same bosses across every stage, so single-target burst and break-focused setups carry the most weight here.
Most recent confirmed endgame lineups (version 4.2)
While 4.4 specifics are pending, the version 4.2 rotation is the most recent confirmed set and is a useful reference for the kinds of enemies and node structures these modes use. Use it to gauge which damage types and roles tend to show up, then adjust once the 4.4 data is out.

For 4.4 specifically, the smart move is to hold off on hard-committing relics and teams to a single damage type until the beta lineups land. The release target is August 5, 2026, and once the closed beta data is out, the confirmed Anomaly Arbitration, Pure Fiction, Memory of Chaos, and Apocalyptic Shadow rosters will replace the 4.2 reference above.
