Arknights Moon Over Water Deadlines: Everything Closing September 25
The event shuts three separate doors at the same second, and none of them reopen.
Stage and shop closing times
The SideStory runs from 04 September 12:00 to 25 September 03:59, and unlocks after clearing main story 1-10. The stage batch labeled "Funeral Parlour" opened later, on 11 September at 16:00. The campus shop shares that same window and closes with the stages.
That leaves roughly half a day of playtime as of writing. If you finished the story but never spent your tokens, tonight is the deadline, not the weekend.
What expires alongside it
The crossover outfits for Makoto Yuki, Yukari Takeba, Aigis and Koromaru leave the store at 25 September 03:59, and the notice explicitly states they cannot be bought with an Outfit Voucher . The daily ten-pull tickets from the login campaign already expired on 18 September at 03:59, so there is nothing to chase there.
Hard expiry list: event tokens, login tickets, crossover outfits. None of these have a recovery path.
Arknights Campus Shop Priority: Buy These Three First
Crossover shops differ from standard Side Story shops because some materials have no equivalent in the permanent store, which pushes them up the priority order.
Limited upgrade materials first
Module materials and the Data Supplement Instrument come first. They stay useful across every version. Second tier is Chip Catalysts and Skill Summaries, the generic costs of elite promotion and mastery. Furniture parts, combat records and green materials sit last.
Short version: convert limited tokens into permanent progression before you buy decoration.
Furniture and cosmetics last
Some furniture and avatars are event-locked and only return on reruns, which are not scheduled. If tokens are plentiful, finish the set. If they are tight, let the decoration go.
Arknights Shadow Chase Event: How to Level the Shadow Gift
Shadow Chase is the limited event running on a separate calendar, and it is the one most players are quietly missing this week.
Dates and reward structure
It opened on 20 September at 16:00 and closes 03 October at 03:59. You raise the Shadow Gift level by participating, and the reward track includes the "Clouds Are Watching You" avatar and the "Joyful Tide" furniture .
Its currency is separate from Moon Over Water and cannot be converted. Shadow Chase has a week more runway, but it draws from the same sanity pool, and that overlap is the real decision.
How much sanity to spend
Work backwards from your module material backlog. If the backlog is large, keep sanity in material stages and do only the daily portion of Shadow Chase. If your upgrade materials are covered, move the surplus into Shadow Gift levels. Exact point thresholds and drops are published on the in-game event page, so check there rather than trusting a static table.
Arknights September Material Stages: Efficiency Comparison
Stage choice should follow the efficiency table, not habit. Here is the Yituliu data synced on 21 September 2026.
The efficiency table
| Material need | Recommended stage | Relative efficiency |
|---|---|---|
| Everything | 14-17 | Highest current tier |
| Purple, blue, green, white only | 14-17 | Same tier |
| Blue, green, white only | MB-6 | 97.5% |
| Green and white only | S3-1 | 94.5% |
| Scattered, mostly green/white | WD-6 | 94.9% |
The new September event stages hit 111.51%, 100.54% and 113.16% on the specific materials they cover. Read that correctly: they beat permanent stages on a narrow set of drops, and only on those.
When the new event stages win
Only when the materials they boost are exactly what you are short of. Otherwise 14-17 is the steadier pick. If your backlog is already small, the sanity is better spent on Shadow Gift levels than on a stage that is 10% more efficient on a material you do not need.
Arknights Mid-Selection Banner: Eyjafjalla and Bagpipe
The Mid-Selection banner runs 17 September 04:00 to 01 October 03:59. Eyjafjalla and Bagpipe share the six-star rate-up at 50% each; Pramanix, Reed and Warfarin share the five-star rate-up at 50%. Eyjafjalla and Pramanix can also be exchanged with Distinction or Commendation certificates during the period.
Role differences
Eyjafjalla is ranged Arts damage output that solves exactly one problem, a missing high-ground caster. Bagpipe's value sits in the Vanguard burst-cycle after elite promotion two: she accelerates the opening.
Certificates or pulls
If you lack high-ground Arts, exchange instead of pulling. Certificate exchange is deterministic. If your Arts coverage is fine, Bagpipe is only worth it for stages where your opening is slow. The deciding question is which stage you are currently stuck on, not which operator ranks higher on a tier list.

Arknights Action Checklist
- Empty the campus shop tonight: module materials, Data Supplement Instrument, Chip Catalysts, skill summaries, then furniture.
- Crossover outfits leave at 25 September 03:59. Buy the ones you want now.
- Push Shadow Chase only to the Shadow Gift tier that awards the avatar and furniture.
- Farm the stage that matches your gap: 14-17 general, MB-6 blue-green-white, S3-1 green-white.
- Decide on the banner by gap: exchange Eyjafjalla if you lack high-ground Arts, do not pull for her.

- 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.
- Honkai: Star Rail 4.6 Planar Fissure Guide: Double Relic Drops and Immersifier Spending
Honkai: Star Rail's 4.6 Planar Fissure event is live, and Planar Ornaments drop double rewards for the duration . The doubled runs are limited and do not reset during the event, so the goal is not farming more but spending the limited runs on the two worlds your roster actually needs.
- 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.

Arknights ran a forced maintenance on 2026-10-09 that shipped four free progression tracks at once: 4 operator records, 4 Paradox Simulations, 4 exclusive modules including the second modules for Shou and Ulpianus, plus 5 Originite Prime in compensation . The dates worth writing into a calendar are 10-15 04:00 for the mid-tier headhunting refresh and voucher store update, and 10-16 04:00 for the Security Service reward refresh .
