Arknights Endfield 1.5 Banner: Si and Typhon

Arknights: Endfield Version 1.5 is heating up ahead of its own banner reveal, with Si, the Feranmut Proxy, and a mysterious Sarkaz archer resembling Typhon standing out as the two names community leaks keep circling back to. The official Version 1.5 livestream airs August 21, 2026 at 7:30 (UTC+8), and until then everything below should be treated as preview footage and community reading rather than confirmed kit data.

Phase 1: Si (Feranmut Proxy)

Time: expected around 9.2 - TBD

Si first showed up as a name during the Version 1.2 livestream, then made her actual story debut in Version 1.4's Yinglung Pass questline as part of the "Homecoming" update. She is described in-lore as the 13th Proxy of the Feranmut Sui, tied closely to the Hongshan Academy of Sciences, and connected to the creation of the Feranmut Hearts used to hold back the Blight in Wuling. That amount of narrative weight is exactly why the community treats her as the strongest lock for Version 1.5's headline banner.

Nothing about her rarity, class, weapon type, or element has been shown yet. Community read-throughs of her ink and scroll motif lean toward a caster or support kit built around her Ink Spirits, but that is speculation rather than anything from an official source.

Phase 2: Typhon (Reconvenor of Typhon)

Time: expected TBD - Version End

The second name making the rounds is a purple-haired Sarkaz operator with dark horns, first glimpsed in the Version 1.4 livestream's Future Version Preview. Early footage shows her at a shooting range in a snowy area, likely tied to the Snow Pine Forest region that comes after Yinglung Pass, and she is often paired with a large mechanical bow or blade-fitted gauntlets depending on the clip. Community shorthand has landed on calling her "Typhon" or "Reconvenor of Typhon," though Hypergryph has not attached an official name yet.

A third character, an unnamed Hongshan Imperial Guard described as calm and resolute, also appeared in the same preview reel, but current signals point to him landing in a version after 1.5 rather than sharing this banner.

Conclusion

Version 1.5 is shaping up as a story-heavy patch that finally puts Si in players' hands after two versions of teasers, while opening the door to the Snow Pine Forest region through Typhon. Nothing here is locked in until the August 21 livestream, so it's worth watching that broadcast before committing Oroberyl.

FAQ

Is Si confirmed for the Version 1.5 banner?

Not officially. She's confirmed as an upcoming playable Operator, but her release version has not been announced by Hypergryph. Version 1.5 is the community's leading guess based on her story appearance and the version cadence.

When does the Version 1.5 livestream air?

August 21, 2026 at 7:30 (UTC+8). This is expected to confirm the actual banner lineup and timing for Version 1.5.

Should I save Oroberyl now for Si or Typhon?

If neither character's kit is confirmed yet, it's reasonable to hold off on final decisions until the livestream, especially since Liino's current banner runs through August 30, 2026.

Will Typhon be a limited character?

That's speculated based on comparisons to Version 1.4's Jue-style short rate-up banners, but it hasn't been confirmed. Endfield has no rerun precedent yet for limited operators, which is worth keeping in mind either way.
