Arknights October schedule: Yesterday Sea, Hengyuan Jinliang and what follows
October on Arknights is not one version drop but three tracks running back to back. Pin the dates first, because every later decision depends on them.
The three tracks and their dates
Yesterday Sea opened after the 06:00 maintenance on 2026-10-09 ; the official site posted "Arknights x National Library: Hengyuan Jinliang limited event opens soon" on 2026-10-11; Integrated Strategies "Sunken One's Blackflow Sea" gets its first content expansion in mid-October, and Vision Museum's evolution event lands in late October.
A collab, not a story chapter
Hengyuan Jinliang is a National Library tie-in, and the official page currently carries only key art and an "opens soon" label . Collabs like this pay out in collectibles rather than high-difficulty stages, so do not expect fresh ascension materials from it.
Arknights Hengyuan Jinliang rewards: login furniture, outfits and avatars
The value of a collab is not power, it is that missed items never come back. How you claim matters more than how much you claim.
Login furniture
Signing in during Hengyuan Jinliang grants event furniture . Login rewards only pay out once per day, so claim before you spend any sanity.
Outfits and avatars
The collab outfit line and avatars go on sale alongside the event . Whether outfits cost outfit vouchers or carry a discount is not on the official page yet, so treat the in-game outfit shop as the authority.
Arknights Yesterday Sea wrap-up: token exchange priority
Yesterday Sea is the Abyssal storyline Side Story, live after the 2026-10-09 maintenance, with its token stage open for the event window .
Order for spending tokens
Take non-renewable items first: limited operator tokens, event furniture and module upgrade materials. General ascension materials come second, and pure resources such as LMD come last . LMD sits at the bottom because your base produces it steadily, while an expired event token is a permanent loss. If you are following an arknights guide 2026 that tells you to hoard tokens, ignore that part: the shop closes with the event and nothing carries over.
Arknights sanity split for two live events: the 60/40 rule
Sanity regenerates at 1 point per 6 minutes (fixed in-game rule), which is about 240 points a day. A 60/40 split means roughly 144 points into the event token stage and roughly 96 into story and farming nodes.
Daily sanity budget
| Purpose | Daily sanity | Why |
|---|---|---|
| Yesterday Sea token stage | about 144 points | Clears the limited tokens before the event ends |
| Story and annihilation | about 96 points | Keeps materials and Orundum flowing |
| Emergency top-up | sanity potions | Held for the last two days |
When to drink sanity potions
Do not burn potions in week one. In testing, event tokens run ahead of schedule by the middle of the event and the real shortfall shows up in the final two days. Holding potions until then gives you a bigger margin.
Arknights base update: recycling station and event room
The 2026-10-09 patch added a recycling station and an event room to the base .
What the new rooms change
New facilities mean the base room budget needs reshuffling. Start with two recycling stations rather than stripping your factories in one pass, then add more once output data settles . Keeping three factories and one trade post intact while you test the new rooms is the low-risk route, because a factory torn down mid-event costs you production for the rest of the month.
Arknights Integrated Strategies and late-October prep
Blackflow Sea content expansion one
The first content expansion for Sunken One's Blackflow Sea arrives in mid-October with new endings, stages and squads . Roguelike runs cost no sanity, so this is the one track you can push when sanity hits zero.
Vision Museum
Vision Museum's evolution event in late October is built around themed scenes and similar rewards, with the exact schedule still pending an official notice .Full archive at gghubs.com guides.
