The 4.6 rotation, Dominance of Oblivion, refreshed on October 5, 2026 and runs until November 11. You are fighting Kafka as the Soulhook Sovereign, an Ichor Memosprite called the Arbiter of the Lost Abyss, and, if you are in Starward Mode, Hoolay as the Fulminating Wolflord. The team advice in one line: bring Fire and Physical, because every boss in this cycle is weak to at least one of them.
Apocalyptic Shadow is not Memory of Chaos with a different skybox. It scores you on breaking a boss's Toughness and bursting it down, and it hands out score multipliers for doing it through Weakness Break. That single scoring rule reshuffles the entire tier list. Teams that shred a crowd in Pure Fiction can stall here, and teams that duel a single tanky boss, which underperform elsewhere, rise to the top.
Who you are fighting in Dominance of Oblivion
| Node | Boss | Known weaknesses | How solid is this |
|---|---|---|---|
| 1 | Soulhook Sovereign (Kafka) | Imaginary, Fire, Wind, Physical | Boss confirmed, weakness set from a single tracker |
| 2 | Arbiter of the Lost Abyss (Ichor Memosprite: Judge of Oblivion) | Fire, Lightning, Imaginary, Physical | Boss confirmed, weakness set from a single tracker |
| 3 (Starward only) | Fulminating Wolflord (Hoolay) | Quantum, Physical, Fire, Wind | Confirmed, two independent sources agree |
A note on that last column, because most sites will not give you one. The three boss identities and the October 5 to November 11 window are confirmed across independent write-ups of the 4.6 endgame lineup. Hoolay's weakness set is corroborated twice. Kafka's and the Memosprite's weakness sets come from one tracker each and should be treated as provisional until you see the bars in your own run. Check the node screen before you commit a team, which is advice you should follow anyway.
Two things fall out of the table. Fire covers all three bosses, which makes a Fire breaker the single most valuable slot in this cycle. Physical covers all three as well, so Boothill is unusually well placed. And the Lightning entry on Node 2 is the opening for a DoT shell that normally has no business in this mode.
One bit of trivia that is also a trap: the Node 1 boss is Kafka, and playable Kafka is a reasonable pick for Node 2's Lightning weakness. You can field her against herself. What you cannot do, in Starward Mode, is field her twice.
Why Break archetypes sit at the top
Apocalyptic Shadow explicitly rewards Weakness Break. Breaking a boss inflates your score, extends the burst, and often triggers the mode's per-stage buffs. That is the whole reason Break and Super Break comps dominate here in a way they never quite do in the point-per-kill modes. If you understand Break Effect and Super Break mechanically, this is the mode that pays you back the most for it.
The Apocalyptic Shadow team tier list
S tier: the boss-killers the mode is built for.
- Firefly Super Break (Firefly + Ruan Mei + a Nihility enabler + Gallagher or Lingsha). The standard-bearer. Firefly converts Break Effect into sustained Super Break damage and keeps the boss's Toughness bar shattered, which is exactly the loop Apocalyptic Shadow scores. When a node offers a Break-flavored buff like Shatterstrike, this team turns it into a landslide.
- Boothill single-target Break (Boothill + Ruan Mei + Bronya or Robin + healer). Apocalyptic Shadow nodes are almost always a single boss or a boss-plus-add, and Boothill is the game's premier one-on-one Break duelist. A turn-advancing Harmony unit and a sustain that does not eat his tempo, and he melts the exact enemy type this mode throws at you.
A tier: elite when the weakness or node lines up.
- Himeko Nova Erudition burst (Himeko Nova + Harmony + Harmony/Nihility + sustain). A frontloaded Fire carry who deletes a Toughness bar in a turn is tailor-made for a boss node that opens with a break, and she is a top pick when the stage buff (a Vanguard-Knight-style opener) favors aggressive burst.
- Acheron hypercarry (Acheron + two Nihility debuffers + Aventurine or Fu Xuan). One of the highest single-target ceilings in the game. She does not score through Break, so she leans on the raw-damage half of the equation, which makes her strongest on a node whose buff rewards straight damage rather than toughness shredding. Read the buff before you slot her.
- Phainon AoE hypercarry (Phainon + buffers + sustain). When a node puts a boss beside meaningful adds, Phainon's AoE covers the whole board and, with a Linebreaker-style node buff, converts that spread into score. The flexible pick for the crowd-plus-boss stages.
B tier: it clears, it does not top the leaderboard.
- Kafka + Black Swan DoT (+ Nihility support + Huohuo). Nearly unkillable and gloriously low-effort, but DoT ramps over time and Apocalyptic Shadow rewards fast breaks and bursts, so the ticks are racing a clock the mode keeps shortening. Great for a comfortable full-star rather than the high-score line, with one caveat specific to this cycle: Node 2's Lightning weakness is the opening a DoT shell usually does not get in this mode, so if you are short a Fire or Physical breaker for that node, this is where Kafka and Black Swan earn their slot.
- Follow-up / FUA core (FUA carry + Robin + Aventurine + sustain). Solid and self-sufficient, and it climbs as the Elation path fills in, but against a single tanky boss it usually trails the dedicated Break duelists on raw break speed.
Starward Mode turns this from a tier list into a roster problem
This page went up without mentioning Starward Mode, which was an omission worth correcting: it has been in the game since Version 4.3, and it is the difficulty anyone chasing a full clear is actually playing.
Clear Difficulty 3 and it unlocks. It is an alternate version of Difficulty 4 that adds a third boss, fought with a third separate team, so three nodes instead of two. Star targets scale to 1.5 times the regular values, which puts the thresholds at 6,000, 7,800 and 9,900 points, with a Prismatic Star at 10,200. Collect all twelve regular stars plus the Prismatic Star, thirteen in total, and you get the limited-time clearance medal. If you would rather not take the constraint, you can revert to Regular Mode and the original rewards.
And there is the constraint, which is the whole reason the tier list above cannot be read straight down:
No character may appear in more than one node lineup. The rule applies across the entire Starward stage, so one shared support will block the third lineup from being submitted at all.
Read the S and A tiers again with that in mind and the problem is obvious. Our two best comps both want Ruan Mei. You cannot have her twice.
| Contested unit | Comps above that both want it | The call |
|---|---|---|
| Ruan Mei | Firefly Super Break and Boothill Break | Give her to Firefly. Boothill runs Bronya or a second Harmony and loses less than Firefly does without Break amplification. |
| Robin | Boothill Break and the follow-up core | Boothill needs the turn advance more than a FUA core needs the damage buff. |
| Aventurine | Acheron hypercarry and the follow-up core | Acheron wants the debuff stacks his talent generates. Give the FUA core a different sustain. |
| Your one good sustain | effectively every comp above | This is the real bottleneck, not the carries. See below. |
So the practical order of operations in Starward Mode is backwards from how people build teams. Assign sustains first, because three nodes need three of them and most accounts have two they trust. Then assign Harmony units, which are the second scarcest category. Carries come last: a carry with no healer scores nothing, and a mediocre carry with a full support shell will clear a node.
If you have fewer than three sustains you can stand behind, that is your pull priority for this cycle, ahead of any damage dealer. Gallagher is free, Lingsha and Huohuo cover the Break comps, and Aventurine and Fu Xuan cover the rest.
Reading the node buffs and weaknesses
Apocalyptic Shadow gives each node a weakness set and a stage buff, and those two facts decide your team more than any tier list does.
- Match the weakness first. A boss weak to Fire and Physical wants your Fire or Physical breakers on the field, full stop. A perfectly ranked team into the wrong element will underperform a "worse" team that breaks the bar.
- Then read the buff. A Break-flavored buff (Shatterstrike) pushes the Firefly and Boothill comps up a full tier. A raw-damage or follow-up buff can lift Acheron or a FUA core past them for that specific node. Do not run the same team into every node on autopilot; each one is its own puzzle.
- Split your roster across every node you are playing. Two teams on the regular difficulties, three in Starward Mode. Put your single-target Break duelist on the tankier boss and your burst or AoE comp on the messier one, and do not stack all your premium units into one node and starve the others. In Starward Mode this stops being a preference and becomes a submission requirement.
The free-to-play line
You do not need a leaderboard team to clear both stars. Apocalyptic Shadow is beatable on well-built four-stars if you cover the weaknesses:
- A Break shell around free and four-star units, leaning on the best free four-star teams, handles most nodes once you match the element.
- Prioritize a sustain you trust and a Harmony buffer over a second carry. The mode punishes deaths and rewards tempo far more than it rewards a fourth damage dealer.
- Grab the current redeem codes for Stellar Jade, and if you are short a breaker for a given weakness, that is your pull priority far more than another generic DPS.
Before you blame a comp for a lost star, audit the fundamentals: correct relic substats, a speed breakpoint that gets your buffers moving before the carry, and enough Break Effect on your breakers to actually shatter the bar in the cycles you are given. For where each unit ranks outside this mode, cross-reference the full HSR tier list and the broader HSR best teams breakdown. Match the weakness, respect the buff, and Apocalyptic Shadow stops being the scary endgame mode and becomes the one your Break team was made for.
