This Arknights beginner guide 2026 lays out the Hengyuan Jinliang window, the login furniture, the bundle and the three crossover outfits, then maps the staged opening of SideStory "Yesterday's Sea" and its YW stage order. It also flags the late-October rerun outfits, the new Annihilation stage Ashstone Theatre, and the certificate shop update, so you can clear everything before 2026-10-30.
Applicable version: as of the 2026-10-15 update (this game has no version numbering; official news dates are the timeline anchor)
Arknights Hengyuan Jinliang Overview: Window And Login Rewards
When the event runs
The window is 16:00 on 2026-10-16 to 03:59 on 2026-10-30 . Note the 16:00 start rather than a maintenance-hour start, and the 03:59 finish, which lands midweek instead of on the last day of the month.
What three login days give you
Three cumulative login days during the event grant furniture including the Fluffy Reading Companion set . Cumulative login counts days, not a consecutive streak, so a missed day does not reset progress as long as you reach three inside the window. Collab furniture like this rarely returns.
Arknights Hengyuan Jinliang Shop: Bundles, Outfits And Packs
Inside the Reading Bundle
The Reading Bundle is on sale from 16:00 on 2026-10-16 to 03:59 on 2026-11-06 and contains 800 Orundum plus the "Shanhai Ta Ye", "Yongle Chang An" and "Tanyuan Kaiwu" avatars . Avatars carry no stats, so the bundle is a collector purchase rather than a power purchase.
The three crossover outfits
Three CROSSOVER outfits arrive: Origin Flows On (Shu), Night Candlelight (Candle Knight) and Signs of a Flourishing Age (Lin Yuhsia), on sale over the same 2026-10-16 to 2026-11-06 window . The official notice states these collab outfits cannot be redeemed with the Outfit Selection Certificate, so hoarded certificates will not cover them.
The Dahuang Qinghe pack
The Dahuang Qinghe pack contains the "Dahuang" interface theme and the "Qingsang" theme scene, and this rerun no longer carries the first-release discount . Rerun packs usually cost more than launch pricing, so check whether your current theme is already good enough before buying.
Arknights Yesterday's Sea SideStory: Staged Opening And YW Stages
The two opening dates
The event stages run from 12:00 on 2026-10-09 to 03:59 on 2026-10-30 and require clearing Main Story 1-10. Stages open in waves: "Reya-Iberia" from 12:00 on 2026-10-09 and "Our Iberia" from 16:00 on 2026-10-16 . Stage two arrives the same day as Hengyuan Jinliang, so that afternoon gets busy.
Stage order for YW-1 to YW-8
Regular stages run YW-1 through YW-8, with YW-TR-1 as the tutorial and YW-EX-1 through YW-EX-8 as the challenge tier . Push them in numeric order and leave YW-TR-1 until your squad is set, rather than forcing it with a story team.
How to get the new Operator
Lugu was added on 2026-10-09, can throw alchemy units to support allies, carries the Ranged, Debuff and Slow tags, and is obtained through the event . Lugu becomes recruitable after clearing YW-4. Treat her as a debuff and slow slot, not a damage dealer.
Arknights Late-October Schedule: Reruns, Annihilation And Shops
Outfit reruns and the Rhodes Island Fashion Review
Both the outfit rerun and the Rhodes Island Fashion Review run from 04:00 on 2026-10-24 to 03:59 on 2026-11-21, covering outfits such as Vina Victoria, the Demon King, Wasteland Lapis Lazuli and Hallberd among others in the Era and Tuest Collect series . Several of these sit on long-standing wish lists, and nothing changes if you buy after 2026-10-24.
Ashstone Theatre replaces Silent Prayer Shrine
The Annihilation commission stage Ashstone Theatre runs from 04:00 on 2026-10-26 to 03:59 on 2027-01-25 and requires clearing Main Story 2-8. It replaces the current Silent Prayer Shrine, which moves into Assumed Operation Targets after closing . Annihilation is a fixed weekly source of Orundum, so clear the three-star line on the new map on day one.
Arknights Mid-October Planning: Orundum And Sanity
Free rewards before paid bundles
The free portion this cycle is the Hengyuan Jinliang login furniture plus the Yesterday's Sea event shop; the paid portion is the bundle, the crossover outfits and the Dahuang Qinghe pack . Take the free part first because it has a hard deadline while the paid part stays on sale until 2026-11-06.
| Priority | Action | Reason |
|---|---|---|
| 1 | Finish three Hengyuan Jinliang login days | Window 2026-10-16 to 2026-10-30, furniture rarely returns |
| 2 | Clear Yesterday's Sea stage two and its shop | Shares the 2026-10-30 deadline with the collab |
| 3 | First clear of Ashstone Theatre | Opens 04:00 on 2026-10-26, a weekly Orundum source |
| 4 | Crossover outfits and bundles | On sale until 2026-11-06, safe to delay |
Where sanity earns more
Yesterday's Sea stages carry bonus event-material drops while Hengyuan Jinliang only ships login and shop content with no event stages . When sanity is tight, spend it on stages with drop bonuses instead of spreading it evenly.More Arknights guides on gghubs.com.
Arknights Hengyuan Jinliang FAQ
When does Hengyuan Jinliang start?
A: 16:00 on 2026-10-16, ending 03:59 on 2026-10-30 .
Do I need seven consecutive login days?
A: No. Three cumulative login days grant furniture including the Fluffy Reading Companion set, and a missed day does not reset the count.

A: No. The official notice states these CROSSOVER outfits cannot be redeemed with the Outfit Selection Certificate.
Is Lugu worth building?

A: It opens at 16:00 on 2026-10-16 and ends at 03:59 on 2026-10-23, earlier than the overall 2026-10-30 deadline .
