Every endgame mode in Honkai Star Rail wipes its progress and rolls out a fresh cycle when Version 4.6 arrives, and each mode returns on its own date rather than all at once. Since these activities hand out a large block of Stellar Jade, knowing exactly when each cycle opens lets you plan your teams and clears around the schedule.
Quick answer: Anomaly Arbitration and Memory of Chaos refresh on September 28, 2026 with the 4.6 update, Apocalyptic Shadow refreshes on October 5, Memory of Chaos refreshes a second time on November 2, and Pure Fiction refreshes on October 19.
Honkai Star Rail 4.6 endgame refresh dates
Version 4.6 goes live on September 27, 2026 for the NA server and September 28, 2026 for the EU and Asia servers. The endgame cycles below refresh at the daily reset for your region, so the exact moment they appear follows your server time.
| Mode | Refresh date | Notes |

| Anomaly Arbitration | September 28, 2026 | Cycle ends November 11, 2026 |
| Memory of Chaos | September 28, 2026 | Second refresh November 2, 2026 |

| Pure Fiction | October 19, 2026 | — |
Each mode’s schedule and rewards
Anomaly Arbitration
The toughest endgame mode refreshes right as Version 4.6 debuts on September 28, 2026. Every player’s prior progression is wiped, so all Trailblazers start the stages from scratch. This cycle stays open until the update wraps up on November 11, 2026, giving you the full patch window to complete it.
Memory of Chaos
Memory of Chaos, also known as the Forgotten Hall, resets alongside the 4.6 update on September 28, 2026. Clearing its stages grants a batch of Stellar Jade, and most of the 12 stages can be handled with the Quick-Clear feature so you only need to finish the final rooms for the rewards.
The mode then refreshes a second time within the patch on November 2, 2026, which means two full reward cycles across Version 4.6.
Apocalyptic Shadow
Apocalyptic Shadow refreshes shortly after the first Memory of Chaos reset, arriving on October 5, 2026. The new cycle brings a fresh enemy lineup and node buffs, and you can auto-complete the first two stages with Quick-Clear once you finish the third.
Clearing stages and earning stars pays out Stellar Jades, Jade Feathers, and Credits. The mode offers up to 12 normal stars plus one prismatic star, so aim for full star coverage for the maximum haul.
Pure Fiction
A new Pure Fiction cycle begins on October 19, 2026, roughly two days ahead of the Version 4.6 second-half launch. Like the other modes, it unlocks when your server reaches its daily reset. Clear the final stage in Starward mode to earn rewards beyond the standard payout.
How to confirm a cycle has refreshed
You’ll know a mode has reset when your previous clear progress is cleared and the stages show a new enemy lineup with updated buffs. If your old completion still appears, the daily reset for your server has not passed yet, so wait until reset on the listed date and open the mode again.
Because Memory of Chaos runs two cycles this patch and Anomaly Arbitration expires on November 11, clear the earlier cycles before their windows close so you don’t leave any Stellar Jade unclaimed.
