This Arknights schedule breakdown turns the second half of October into something you can act on. It covers what three sign-in days actually give you, whether the bookstore bundle is worth 800 Orundum, how the Graystone Theater swap on October 26 changes your weekly Annihilation routine, and why 180,000 LMD is the real wall before any Elite 2 promotion.

Arknights October schedule: the Hengyuan Jinliang and Graystone Theater timeline
The official notice published on October 11 lays out four separate windows: sign-in from October 16 16:00 to October 30 03:59, the store bundle from October 16 16:00 to November 6 03:59, new outfits in the same window, and rerun outfits from October 24 04:00 to November 21 03:59.
Three dates people mix up
October 16 16:00 starts the sign-in, the bundle, and the three crossover outfits together. October 24 04:00 opens the rerun outfits and the Rhodes Island Fashion Review, which is a different window from the sign-in ending on October 30 03:59. October 26 04:00 opens Graystone Theater, which stays open until January 25 2027 at 03:59.
The stream comes before the celebration
Producer Letter #70 states that the 2026 Thank-You Celebration preview stream runs October 24 at 19:30 and will cover celebration events, a new SideStory, the next limited banner, and later version plans . Anything you read about limited operators before that date is community guessing.
Arknights Hengyuan Jinliang: sign-in versus store spending
Hengyuan Jinliang is a light crossover event. The official notice confirms only two player-facing rewards: three cumulative sign-in days for furniture including the Fluffy Reading Companion, and a limited bundle in the store . There is no new combat stage, so the event costs zero sanity.
Why three sign-in days is cheap value
The window is 14 days long, so missing a day costs nothing. The furniture itself is one-off crossover content that will not return through normal shops, which matters if you keep complete furniture sets.
The bundle math
The Book Bundle contains 800 Orundum plus the avatars Mountain Sea Night Walk, Eternal Chang'an, and Tracing Origins . At the usual 600 Orundum per pull, 800 Orundum is roughly 4.4 pulls at most, so buy it for the avatars, not for the pulls.
Arknights Graystone Theater: Annihilation before and after the swap
Graystone Theater opens October 26 04:00, requires Main Story 2-8, and replaces Doxology Shrine. This is a replacement, not an extra stage: the old stage gets retired into the assumed-target pool once it closes.
The weekly ceiling does not move
Annihilation Orundum is capped at 1800 per week . Changing the map does not change the cap, only how long each run takes and how stable your clear is. Spend the first week learning spawn order with a cheap squad instead of burning sanity on retries.
Clear the old week first
Finish your 1800 before October 26, then switch immediately. If you leave part of the weekly cap unfinished, you will have to farm the remainder on an unfamiliar map.
Arknights October sanity budget: spending 240 points a day
Sanity recovers one point every six minutes, for 240 points a day from natural regeneration . There is no new combat stage this month, so everything goes to farming stages and Annihilation.
Three account brackets
| Account stage | Daily sanity split | Reason |
|---|---|---|
| New (story before 2-8) | 160 story, 80 materials | 2-8 unlocks Graystone Theater |
| Mid (two or three Elite 2) | One Annihilation run, 200 materials | Lock the 1800 Orundum cap first |
| Veteran (materials surplus) | Annihilation plus chip stages | Chips gate Elite 2 |
Fill gaps, do not stockpile
Promoting a six-star to Elite 2 costs 180,000 LMD . Farm the LMD stage to that number first, or you will end up with every material and no money.
Arknights operator investment: who gets Elite 2 first
No new operators arrive in the October notices, so promotion targets come from your existing roster. Rank by two questions: can this operator enter the current hard content, and do I already own a substitute?
Priority order
Promote operators who work in both Annihilation and story stages, because both are weekly chores. Single-purpose counters come second. Graystone Theater becomes a weekly obligation after October 26, so anyone who handles its spawn pattern cleanly moves up.
Counting the material gap
Track three separate lines: chips, LMD, and promotion materials. Do not farm all three at once. Arknights materials drop at fixed rates per stage, so pick one stage per material instead of spreading sanity thin.
Arknights outfits and bundles: worth the Originite?
Short answer: pure combat players can skip all three crossover outfits, while collectors should buy in the order Shu, Blaze the Igniting Spark, and Swire the Elegant Wit, because Shu sees the most play and therefore the most screen time.
Three account types
Free-to-play: ignore outfits and bundles, keep Originite for the limited banner. Monthly card: if you hold more than 30 Originite, buy one outfit and keep the rest for whatever the October 24 stream reveals. Collectors: buy all three, but note the notice says crossover outfits cannot be exchanged with the outfit voucher item .
The rerun window is not a second chance
The rerun outfits from October 24 04:00 to November 21 03:59 cover a different set, including Vina Victoria, the Demon King, and Wasteland Lap-lap Land . These three crossover outfits are not included, so "I'll wait for the rerun" does not work here.

Game Guides
- Palworld 1.0.5 Breeding Guide: Mutation, Four Passives, and Cake Economics
Version 1.0.5 only fixes textures, but the breeding line changed for good when 1.0 added Mutation, a low-probability upgrade during breeding. Getting reliable four-passive Pals is still an engineering problem: start from clean parents, merge narrow passive pools, and treat Mutation as a bonus instead of a plan.
- Reverse: 1999 4.0.0 Yingmenzhe: 40 Sign-In Pulls, Insight III Order, Real Costs
Version 4.0.0 landed on September 24, and the hardest number in its reward list is 40 limited sign-in pulls, followed by a guaranteed-new six-star and a selectable six-star Reverie character. Claim the sign-in before you spend anything, then decide who gets Insight III, because doing it backwards trades future pulls for current power.
- Love and Deepspace 6.0 Home Guide: The 6000 Diamond Path, Bonding, Stamina
Version 6.0 turned the home space into an income system rather than a backdrop: cooking, home crafting, gardening, and design mode all ship together, and the official notes state that playing the home content yields over 6000 diamonds in total. To actually collect that, make the daily home loop a fixed habit before touching anything else.
- Honkai: Star Rail 4.6 Planar Split: Double Planar Ornaments and Relic Trade-offs
Planar Split opened on October 11 at 11:00 and doubles exactly one thing: Planar Ornaments from the Simulated Universe. Cavern relics are not included. With Immersifiers costing 40 Trailblaze Power each and 240 power a day, you get six runs a day, so spend every one of them on the two-piece slot you are still missing.
- Genshin Impact 7.1 Snowball Event Guide: Primogems, Dual Cryo Banners, Abyss 12
The Snowball event that opened on October 19 at 12:00 is the only new gameplay in the back half of Genshin Impact 7.1, and it sits next to two Cryo banners that have been live since October 8 at 16:00. Do the event first, count the primogems second, and pull third, because a 90-pull guarantee costs 14,400 primogems before you even discuss who is stronger.
- Wuthering Waves 3.7 Tower of Adversity: Three Teams, Echo Stats, Real Costs
Tower of Adversity in Wuthering Waves 3.7 still forces three teams that share no characters, and that single rule decides how you spend everything else. Fix your three carries first, then build echoes on a 4-3-3-1-1 cost split: 60 percent crit rate and 120 percent crit damage on the carry, energy regen only on supports.
- Zenless Zone Zero 3.2 Double-Drop Window: Drive Discs, W-Engines, Battery
Battery, not pulls, is the real bottleneck in Zenless Zone Zero 3.2. With the Data Bounty training-room double reward live since October 12, the correct order is character ascension materials first, drive disc main stats second, sub-stats never chased past 60 percent crit rate and 120 percent crit damage.
- Palworld 1.0.5 Base Production Lines: Work Suitability and the Ancient Bark Chain
A Palworld base should not build a little of everything. Lay it out in three zones — gathering, crafting, hauling — and put exactly one Pal on each station, with everything else shifted to transport or planting. Since v1.0.4 dropped Ancient Bark gathering to Work Suitability Lv. 1, the early wood chain costs far less to start .
