Arknights: Endfield RE-Factor Headhunting #1 countdown
Arknights: Endfield RE-Factor #1 unlocks worldwide at the same moment
24 September 2026
The 24 September 2026 date is Hypergryph's own, from the [Dreamscape of Wind and Snow] Version DEV Comm of 22 August. The hour comes from a second official channel: GRYPH FRONTIER's Japanese press release of 21 August states 13:00 on 24 September — a Japanese release read as JST, which equals 12:00 server time, exactly how the Liino banner opened (12:00 server time, per the [Homecoming] update notes). Those two readings corroborate each other, so this countdown runs to 13:00 JST / 04:00 UTC. Until 25 August this page said no hour was published — the JP press channel had it all along, the same channel that carried the version date before the news hub did. The end is worded as until the next version-update maintenance, not a calendar date.

You have Oroberyl saved and one question: is the 24 September banner worth it — and is the ‘Si banner’ you keep seeing on countdown sites even real? Short version: the 24 September date is official, the pool is all reruns with Yvonne up front, and the Si banner exists on other people’s countdown pages, not on Hypergryph’s.
What Hypergryph actually announced
The [Dreamscape of Wind and Snow] Version DEV Comm of 22 August names it in full: [Resplendent Spectrum] RE-Factor Headhunting #1, opening 24 September 2026 — three weeks into version 1.5, which itself starts 2 September.

| Fact | Status |
|---|---|
| Opening date | 24 September 2026 — official |
| Rate-up | Yvonne (Cryo Striker) — official |
| 6★ pool | Yvonne / Ember / Lifeng / Ardelia / Last Rite / Pogranichnik — official |
| Paired weapon scout | [Tag Artist Issue] — the 6★ Artzy Tyrannical rate-up, opening the same 24 September (DEV Comm) |
| Opening hour | 13:00 (JST) / 04:00 UTC — official, via the JP publisher’s press release |
| End | Until the next version-update maintenance — tied to the 1.6 handover, not a calendar date |
| New operators | Typhoeus debuts on his own special scout — announced in the JP press release only (see below) |
The guarantee actually changes the math
RE-Factor is Endfield’s rerun system, debuting here, and its pity is the interesting part. Per the DEV Comm: a 5★ within 10 attempts, a 6★ within 80 — and the 80-count is shared across all RE-Factor banners, carrying over until a 6★ drops. Sixty pulls here without a 6★ are sixty pulls of progress on RE-Factor #2. That makes partial investment rational in a way version-debut banners are not: you cannot strand pity by walking away.
The paired weapon scout, same day
The DEV Comm also opens [Tag Artist Issue] on 24 September — the weapon-side RE-Factor, with the 6★ Artzy Tyrannical on rate-up. Same naming family as [Bedazzled Issue], Liino’s paired weapon banner: that is how these weapon scouts have been named so far.

About the “Si banner”
Some countdown sites are running clocks for a 1.5 Si (Feranmut Proxy) banner and telling you to save Oroberyl for her. Check the sources they do not link: the DEV Comm never names Si, and she does not appear on Hypergryph’s official 33-entry operator roster. We know the expectation well — this site carried the community’s Si roadmap too, and scored it wrong when the DEV Comm posted. The 25 August 2026 check recorded: the scouts announced for 1.5 were the Yvonne rerun on this page with its paired [Tag Artist Issue] weapon scout, Typhoeus’s special scout, and a further weapon scout in the JP release — Si was on none of them. If that changes, the change lands here the same day, linked to the announcement.
Correction, and what the JP press release adds
This page’s first version, published the morning of 25 August, said no new operator was announced for 1.5 at all. That was wrong by one channel. GRYPH FRONTIER — the publisher’s Japanese arm — put out a press release on 21 August that goes further than the DEV Comm in three ways, none of which have appeared on the English news hub:
- Typhoeus debuts. The 6★ Striker — roster entry 01/33, one of the two entries we flagged as having no banner history — gets his own special scout (named 「冬狩」 in Japanese; no English name has been published), running from the version opening to 30 September, 13:00 JST. The community roadmap’s “Typhon” note appears to have been pointing at the right operator after all — it was the “Si in 1.5” half that was wrong.
- Purrchena is a login gift. The 5★ Defender — roster entry 02/33, the other no-banner-history entry — is distributed free through an in-version event.
- This banner’s hour and end. 24 September at 13:00 JST, running until the next version-update maintenance.
The lesson is the one this site keeps re-learning: the publisher’s press channels carry facts the official news hub does not. The version date arrived that way; so did all of this.

Sources
Everything official on this page is from two Hypergryph pages: the [Dreamscape of Wind and Snow] Version DEV Comm of 22 August 2026 — the banner’s full name, the 24 September date, the Yvonne rate-up, the six-operator pool, the Permit/Oroberyl currencies and the 10/80 shared, carrying-over guarantee — and the official operator roster, 33 entries, no Si, checked 25 August 2026. The 2 September version date is GRYPHLINE’s, via its 21 August press overview; the record is on our 1.5 page. The claim that other countdown sites billed this as a Si banner refers to those sites’ pages checked on 25 August 2026; we do not link them, and nothing they assert is treated as fact here. No hour and no end date exist in any official source — where this page has no number, none has been published.
FAQ
When does the Endfield RE-Factor banner start?
24 September 2026 at 13:00 (JST) — 04:00 UTC, 21:00 on 23 September Pacific. The date is from Hypergryph's DEV Comm of 22 August; the hour is from GRYPH FRONTIER's Japanese press release of 21 August, and it matches the 12:00-server-time pattern the Liino banner set. It runs until the next version-update maintenance — the 1.6 handover — rather than to a calendar date.
Who is on the RE-Factor banner?
Yvonne, the Cryo Striker, is the announced rate-up. The full 6★ pool is Yvonne / Ember / Lifeng / Ardelia / Last Rite / Pogranichnik — all reruns; no one debuts on this banner. One correction from the day this page first published: 1.5 does have a debut elsewhere — the 6★ Striker Typhoeus gets his own special scout, announced in the publisher's Japanese press release of 21 August (not in the DEV Comm), running from the version opening to 30 September, 13:00 JST.
What is RE-Factor Headhunting?
Endfield's announced rerun system, debuting with this banner. Per the DEV Comm: pulls use Chartered HH Permits or Oroberyls, a 5★ operator is guaranteed within 10 attempts and a 6★ within 80 — and that 80-count is shared across all RE-Factor banners, carrying over to future ones until a 6★ drops. Partial progress on this banner is not wasted.
Is this the Si banner?
No — and the 'Si banner' does not exist anywhere official. Several countdown sites bill 1.5's banner as Si (Feranmut Proxy) and advise saving Oroberyl for her. Hypergryph's DEV Comm never names her, and Si does not appear on the official 33-entry operator roster at all. The scouts announced for 1.5 are this rerun with its paired [Tag Artist Issue] weapon scout, Typhoeus's special scout (JP press release), and a further weapon scout in the JP release — none of them Si. If Si is ever announced, we publish it the same day — with a link to the announcement.
Should I save Oroberyl for this banner?
The decision facts: everyone in the pool is a rerun, so this is the announced second chance at Ember, Lifeng, Ardelia, Last Rite and Pogranichnik if you missed them. The shared, carrying-over 80-pull guarantee means pulls spent here still count toward a 6★ on any future RE-Factor banner. What no official source supports: saving for a 1.5 Si banner that has never been announced.
When does the RE-Factor banner end?
It runs until the next version-update maintenance — the 1.6 handover — per the Japanese press release, which words the window as 24 September 13:00 to before version-update maintenance rather than giving a calendar end. Note that 24 September falls inside version 1.5 (which starts 2 September), so the banner opens mid-version, three weeks in.
