Written against the current Honkai: Star Rail best teams tiers, this Honkai: Star Rail team comps breakdown covers the Planar Fissure rules, the run cap, how Immersifiers relate to Trailblaze Power, which worlds drop which ornaments, and what to farm once the event ends. Timings and run counts follow the in-game event interface.

Honkai: Star Rail 4.6 Planar Fissure: rules and run cap
How the doubling works
During the event you can obtain double rewards from the Immersion device when challenging Simulated Universe, so spending an event run plus an Immersifier or Trailblaze Power grants an extra reward on top of the normal drop. Remaining runs and the event cap show in the event interface ).
The cap does not refill
Doubling runs do not reset while the event is active, so once they are gone they are gone . The steady play is to schedule your two biggest gaps inside the window and keep the rest on a normal cadence, because a run spent on a set you already own is a run wasted.
Honkai: Star Rail ornament extraction: Immersifiers and power
The extraction loop
Planar Ornaments come from Planar Ornament Extraction in the Simulated Universe, where you spend an Immersifier after beating elite or boss enemies, at 40 Trailblaze Power per run . Equipping 2 pieces activates the set bonus .
Should you use deep Immersifiers
The event doubles the drop, not the value of a deep Immersifier, so burn the doubled runs on standard Immersifiers and keep the deep ones for targeted farming outside the window (reasoning: the event only multiplies the Immersion device payout).
Honkai: Star Rail Planar Fissure: which world to farm
| World | Sample sets | Best for |
|---|---|---|
| World 8 | Celestial Differentiator, Penacony Land of Dreams | General damage and support |
| World 7 | Arena, Broken Keel | Damage dealers and buffers |
| World 6 | Salsotto | Crit-oriented damage |
| World 3 | Space Sealing Station, Fleet of the Ageless | Early general sets |
| Divergent Universe | Punklorde and the new drop point | Latest additions |
Pick worlds by your roster's gaps: fill the slot that is missing a 2-piece bonus first, then think about rerolling substats. Supports sitting on stand-in sets are usually the fastest win in the list. Substat chasing is a poor use of a doubling window, because doubling multiplies quantity and not quality (reasoning: drop mechanics).
Honkai: Star Rail 4.6 resource plan during the event
| Window | Action | Reason |
|---|---|---|
| First week | Fill your two biggest world gaps | Runs are limited and do not reset |
| Second half | Farm the second-priority set | Get the main team finished |
| After the event | Reroll substats on normal stamina | Quality comes from volume |
| Throughout | Do not reshuffle teams for the event | Stable teams reveal real gaps |
Trailblaze Power drains fast during the window, so total up the week's budget before buying any refreshes (reasoning: a flat 40-power cost per run). A single week of doubled runs can consume several days of normal income, which is why the two-world rule matters more than raw volume. If both of your main team's ornaments are already done, spend the runs on the second team instead of letting them expire, since an untouched run has exactly the value of no run at all.
Honkai: Star Rail 4.6 pacing: what comes after the event
Where the event sits in the patch
Version 4.6 launched on 2026-09-28 and Planar Fissure opened on 10-11 . It is a mid-patch supply event that lands well before the next version, so there is no need to rush around it.
What to farm afterwards
Switch stamina back to relic and trace caverns and work down your main team's weakest link. Ornament set bonuses flatten out once the 2-piece is complete, so the same stamina returns more in relic slots than in more ornament runs (reasoning: gear upgrade curves). If a support character is running a stand-in set, that is usually the cheapest upgrade left on the board, and it costs no event runs at all.
Honkai: Star Rail common Planar Fissure mistakes
Treating it as a substat event
Doubling changes drop quantity, not substat distribution. Expecting a perfect piece from the window is a lottery ticket, not a plan . Plan around a usable 2-piece bonus and treat good substats as a bonus rather than the objective.
Hoarding Immersifiers
Storing Immersifiers for the window helps, but only if you actually spend them; a stockpile left untouched when the event closes has bought you nothing at all.
Forgetting the cap does not reset
Unused runs are simply lost, so schedule your first pass on the day the event opens .More guides at gghubs.com.

- Palworld v1.0.5 Tower Boss Order Guide: Elements, Counters and Squad Choices
Palworld's v1.0.5 patch (2026-09-15) only fixed texture loading, so what actually shapes tower runs is the 1.0 release itself: the boss count expanded from 7 towers in early access to 9, the level curve runs from 10 all the way to 80, and the new Sunreach sky islands and World Tree finale sit at the end of it . Clearing towers is less about raw investment than about picking Pals that exploit each boss's element.
- Reverse: 1999 Version 4.0.0 Second Half Guide: Drake, the October 15 Banner Swap and Free Rewards
Reverse: 1999 has moved into the second half of version 4.0.0, and the banners swap on October 15: Drake arrives as a new standard six-star Beast character, while a pick-your-own rate-up runs with Quniang, Liangyue, Nana, Lucy and Nodica selectable . The first half's limited SP Crossbow banner closes at the same point, so October 15 is a clean dividing line.
- Love and Deepspace Xavier Birthday Guide: Wish Upon This Moment Banner Window
Love and Deepspace's Xavier birthday event is live, and the birthday five-star Memory is obtainable from 2026-10-11 at 05:00 to 2026-10-18 at 04:59 (source: official birthday calendar and birthday Memory announcement, 2026-10-08). The window is only seven days and it is a single-character banner rather than a pooled one, so the budget is easier to plan, provided you count your tickets and diamonds before you start pulling. The single target is the main advantage: there is no risk of boosting the wrong Memory and no need to compare three candidates.
- Genshin Impact 7.1 Imaginarium Theater Guide: Ice, Hydro and Anemo Stacking
The October 2026 Imaginarium Theater rotation locks the playable elements to Ice, Hydro and Anemo, and its core mechanic grants one stack of Frost Benediction whenever your party triggers Swirl, with each stack adding 80% Swirl damage and 12% crit damage up to 3 stacks . So the rotation is not about raw damage but about Swirl frequency, getting the blessing to full stacks as fast as possible.
- Wuthering Waves 3.7 Tower of Adversity Lineup Guide: Mid Tower Splits and Side Tower Stamina
The Wuthering Waves 3.7 Tower of Adversity refreshed on October 13, and this rotation cuts Havoc resistance on the left tower's fourth floor, which clears the way for Havoc teams. The mid tower remains the hardest part of the cycle, with Sunmoon, Cartethyia and Phrolova squads still carrying it, Zhanfei usable, and Galbrena needing Qiuyuan to reach full shape. If you only need the rewards, the side towers auto-clear and your stamina belongs to the mid tower.
- Zenless Zone Zero 3.2 Shiyu Defense Guide: Three Teams and the October 2 Rotation
Zenless Zone Zero's October 2 Shiyu Defense rotation runs through October 16 and ends in a three-room score check where each room caps at 25,000 points for an S rank and the total reaches 100,000 (source: in-game Shiyu Defense interface plus creator testing, 2026-10-02). If you only want the Polychrome, getting all three rooms to S is enough, because the reward gate is the S rank and not the total.
