When Honkai Star Rail 4.6 goes live, Anomaly Arbitration, Pure Fiction, Memory of Chaos, and Apocalyptic Shadow all get a fresh cycle with new enemies and new debuffs. Datamined lineups for each mode are already circulating, and knowing which bosses show up lets you build the right elements and set your damage plan before the reset hits.
Quick answer: The headline bosses for 4.6 are Soulhook Sovereign (Kafka), Arbiter of the Lost Abyss, and Fulminating Wolflord (Hoolay) in Apocalyptic Shadow; Argenti anchors Pure Fiction’s hardest node; Murata Graphia: Founding Artist closes Memory of Chaos; and Anomaly Arbitration’s King in Check pairs Moonlit Pegasus and Lighthouse with an unrevealed boss.
Note: These lineups come from pre-release datamining and can shift before the update ships. Treat them as a planning aid, not a final word.
Apocalyptic Shadow 4.6 bosses
With Starward mode in place, Apocalyptic Shadow’s final stage runs across three separate nodes, and each one puts a different single boss in front of you. This mode rewards single-target and Break damage, so build toward the weakness each boss carries.
| Node | Boss |
|---|---|
| Node 1 | Soulhook Sovereign (Kafka) |
| Node 2 | Arbiter of the Lost Abyss (Ichor Memosprite) |
| Node 3 (Starward mode) | Fulminating Wolflord (Hoolay) |
Memory of Chaos 4.6 enemy lineup
All 12 Memory of Chaos stages refresh, but the Quick-Clear feature handles most of the early rooms. You really only need to sweep the final stage’s three nodes to collect the full reward set. Blast and single-target damage matter most here.
| Node | Enemies |
|---|---|
| Node 1 | Rocking Rebel, Decaying Shadow, Borisin Warhead: Hoolay |
| Node 2 | Moonlit Pegasus, Noontide Gryphon, Unknown Boss |
| Node 3 (Starward mode) | Daybreak Squadron: Azurewing, Present Inebriated in Revelry, Murata Graphia: Founding Artist |
Pure Fiction 4.6 Stage 4 enemies
Pure Fiction has four stages, and the first three fall easily. Stage 4 is the one worth prepping for, and it leans hard on area-of-effect damage since you face dense enemy waves across three nodes. Argenti sits at the end of the Starward node.
| Node | Enemies |
|---|---|
| Node 1 | Furiae Warrior, Meteoric Eagle, Furbo Journalist, Automaton Hound, Abundance Sprite: Golden Hound, Furiae Praetor, Black Tide’s Corroded Axe, Imaginary Weaver, Flame Reaver of the Deepest Dark |
| Node 2 | Sableclaw Wolftrooper, Abundance Sprite: Wooden Lupus, Furbo Journalist, Cloud Knights Patroller, Juvenile Sting, Dreamjolt Troupe’s Sweet Gorilla, Alloy Pommy, Alloy Mechatron: King Pom-Pom |
| Node 3 (Starward mode) | Silvermane Cannoneer, Silvermane Gunner, Furbo Journalist, Eclipse Wolftrooper, Wraith Warden, The Ascended, Argenti |
Anomaly Arbitration 4.6 lineup
Anomaly Arbitration splits into three Knight stages of similar difficulty and a much harder King in Check finale. You clear the Knights in any order with three separate teams, and each Knight you beat lowers the King’s Enemy Traits before the final fight.
| Stage | Enemies |
|---|---|
| Knight 1 | Joy Ascendant, Daybreak Squadron, Alloy Mechatron: King Pom-Pom |
| Knight 2 | God-Devourer Offspring, Aurumaton Spectral Envoy, Paramount Bliss Inverted: Illwish Archlotus |
| Knight 3 | Cyclonic Swarm Mother, Abundance Sprite: Malefic Ape, Harbinger of Death: Swarm Nightmare |
| King in Check | Moonlit Pegasus, Lighthouse, Unknown Boss |
Tip: Anomaly Arbitration runs on its own reset schedule, separate from the two-week rotation of the other three modes. It also pays out cosmetics and Lone Stardust rather than Stellar Jade, so it never conflicts with the rest of the endgame calendar.
When the modes refresh
Each of these cycles opens when the 4.6 update installs. Memory of Chaos and Anomaly Arbitration are expected to swap to their new rotations right as the version goes live, while Apocalyptic Shadow and Pure Fiction carry a short overlap from the previous phase before their own reset. Anomaly Arbitration always resets on a Wednesday after version maintenance and runs on a roughly six-week window.
Because two nodes still list an Unknown Boss and the lineups are pulled from pre-release testing, expect small changes before launch. Lock in your elemental coverage now, especially the single-target Break setups for Apocalyptic Shadow and wide area damage for Pure Fiction, and you will be ready the moment the reset lands.
