Where to Watch
The program premieres on the official Arknights: Endfield YouTube channel. The embed below goes live at 11:30 UTC.
The official description sets the theme: “Ink breathes across the scroll, while clouds and waters drift through open space. Endministrator, brush and ink await. Unfurl the scroll and step into a painted sanctuary where body and mind can find repose.”
What to Expect From the Sanctuary of Ink Program
This was written before the stream. The official answers are in the Sanctuary of Ink recap; the notes below are kept for reference, with corrections where the leaks were wrong.
Si and the Yuanyuan Manor ink scroll (teased officially)
The closing teaser of the Dreamscape of Wind and Snow program showed Si inviting the Endministrator to the Abode of Recuperation to enter a special ink scroll called Yuanyuan Manor: a misty cavern of waterfalls and autumn trees. “Sanctuary of Ink” and a description about a painted sanctuary “where body and mind can find repose” line up with that teaser almost word for word, so expect Yuanyuan Manor to be the new area or event hub.
Si is the 13th Sui Proxy. If you want the background before she arrives, read our Feranmut and Sui Proxies explainer and the Si, Hongshan Guard and Sarkaz dream traveler lore post.
“Core Chapter Version” (from the key visual)
The key visual labels this a Core Chapter Version, which points to a main story chapter continuation rather than a side-story or event-only patch. Expect a new story segment alongside the area.
Version 1.6 release date (in-game schedule, not yet official)
The 1.5 events, including Runners’ Steeplechase, end at the version maintenance on October 15, 2026 at 06:00 UTC+8. That makes October 15 the expected Version 1.6 launch, about nine days after the program. For comparison, the 1.5 program aired August 21 and the patch launched September 2.
Leaked banners (unconfirmed)
| Phase | Operator | Leaked element / class | Leaked start |
|---|---|---|---|
| Phase 1 | Si (13th Sui Proxy) | Heat (Fire) Caster | October 15, 2026 |
| Phase 2 | Ye Minghui (Hongshan Imperial Guard) | Electric Vanguard | November 5, 2026 |
Official result: the dates held, the details did not. Si is a Cryo Supporter on [Rejuvenation] (October 15 to November 5), and the November 5 banner is Argent Flow, an Electric Guard, on [The Hearth Fire Beckons the Starry Flow]. The program never used the name Ye Minghui. Full kits are in the recap.
Other teased systems
The 1.5 program also teased a ranch system, an Arena of Games event building on Trial of Swordmancy, and a harder second Contingency Contract iteration. Any of these could get dates on October 6.
Redemption codes
Previous programs have shipped codes and free rewards (the 1.4 program gave out ENDFIELDRENEW). Check our codes page after the stream; we add new ones as soon as they are announced.
How to Prepare Before October 6
- Save Oroberyls and permits. If Si is the Phase 1 headliner, she will be the first new limited operator in weeks. The pity calculator shows how far your current stash goes.
- Finish the 1.5 events before the October 15 maintenance, Runners’ Steeplechase included.
- Check the meta on the tier list so you know which roles your roster is missing before the new kits drop.
