Arknights Endfield Upcoming Operators Guide: Si, Hongshan Imperial Guard and Sarkaz Archer Preview

The Version 1.4 "Homecoming" update of Arknights: Endfield is a half-year-anniversary blowout — but it also dropped a Future Version Preview that has the community's Oroberyl budgets under siege. Three names now sit on every saving spreadsheet: Si the Feranmut Proxy, the Hongshan Imperial Guard, and the Sarkaz Archer. None are pullable today, but all three are confirmed on the roadmap, and the Sarkaz Archer in particular has players comparing her to Typhon from the main Arknights story.

This guide does two things. First, it collects everything officially revealed about these three upcoming Operators — no kit leaks, no invented stats, only what the livestreams and previews have shown. Second, it answers the question every Pioneer is actually asking right now: should I spend on Arcane and Liino in Version 1.4, or skip both to bank Oroberyl for Si and beyond? The answer depends entirely on your roster, and the pity math below makes it concrete.

If you need Oroberyl to either chase the current banners or stockpile for the future, you can top up safely through Topuplist and head straight to the Arknights: Endfield top-up page for Origeometry packs and Monthly Passes.

Who Are Si, the Hongshan Imperial Guard, and the Sarkaz Archer?

According to the official Arknights: Endfield site and the Version 1.4 livestream, the three are part of the game's forward roadmap rather than the current banner rotation. They were shown in the Future Version Preview segment, which is how Hypergryph traditionally teases operators one or two versions ahead. That cadence matters for planning: a tease today usually means a playable banner one or two patches later, not next week.

The key takeaway for gacha planning is simple. Arcane (Phase 1) and Liino (Phase 2) are the Version 1.4 headlines and are available now. Si is expected in Version 1.5, and the Hongshan Imperial Guard and Sarkaz Archer are slated for versions after that. If your heart is set on the future trio, every Oroberyl you sink into 1.4 is Oroberyl you will not have for them.

What We Know About Each Upcoming Operator

All three have been revealed but not fully detailed. Treat the kit descriptions below as "what is confirmed from the preview," not as final numbers.

Si — the Feranmut Proxy

Si was first teased as far back as the Version 1.2 livestream and re-appeared in the Future Version Preview of 1.4. She makes her first story appearance in Version 1.4 — specifically in the new Yinglung Pass area of Wuling, the first region you reach in the update. Her banner is most likely Version 1.5.

What is confirmed:

• Codename / title: Si the Feranmut Proxy (Feranmut being the draconic entities of Arknights lore).

• Gender: female (per preview framing).

• Status: confirmed upcoming Operator, not yet a banner unit.

• Story role: debuts in the Wuling storyline during 1.4 before becoming pullable in 1.5.

What is not confirmed: rarity, class, element, weapon, and skill kit. Anyone selling you "Si is a 6-star Nature DPS" is guessing. Plan around her existence and timing, not her stats.

Hongshan Imperial Guard — the Wuling Swordsman

The Hongshan Imperial Guard was revealed as an upcoming character in the Version 1.4 livestream. He is described as calm and resolute, with a backstory hint that he was once driven into utter despair — a classic setup for a later, heavier release.

What is confirmed:

• Affiliation: tied to Hongshan / Wuling. The Hongshan Academy of Sciences governs Wuling, and several playable Operators (Da Pan, Lifeng, and the Sarkaz patrol captain Mi Fu) already connect to that region.

• Demeanor: calm, resolute.

• Backstory seed: a past of despair, implying a significant story arc.

• Kit: no confirmed details yet.

Given the "Imperial Guard" name and the Wuling/Hongshan framing, the community broadly expects a Guard-class melee Operator, but that is expectation, not confirmation. He is slated for a version after Si.

Sarkaz Archer — the Dream-Walking Sarkaz

The Sarkaz Archer is the most visually striking of the three. The Future Version Preview showed a character with purple hair and Sarkaz horns, wielding large mechanical gauntlets with blade-like weapons, and leaning into aggressive melee combat. Multiple outlets noted she bears a striking resemblance to Typhon, the Sarkaz witch from the main Arknights storyline.

What is confirmed:

• Race: Sarkaz.

• Design: purple hair, Sarkaz horns, oversized mechanical gauntlets with blades.

• Combat style: aggressive melee.

• Lore flavor: described as wandering through dreams and collecting stories from around the world, and implied to encounter the Endministrator later in the story.

• Timing: expected to arrive after Si and the Hongshan Imperial Guard — the furthest out of the three.

Like the others, her exact class, element, and kit remain unpublished. She is a "watch this space" unit rather than a "save everything for her right now" unit.

The Version 1.4 Dilemma — Arcane and Liino Are Live Now

While the future trio waits in the wings, Version 1.4 is the present temptation. The update launched in mid-July 2026 and runs in two phases, each with its own limited 6-star. This is the real consumption decision: spend now, or hold.

Arcane (Phase 1) at a Glance

• Banner: "North Yearns the Rift Vigile" — Version 1.4 Phase 1.

• Rarity / Class / Element: limited 6-star Caster, Nature element, Arts Unit weapon.

• Dual role: Arcane is built around two stances — an INT (Intellect) mode that deals Nature / Corrosion damage, and a WILL mode that provides enemy grouping, debuffs, and Arts Infliction spread (control-flavored support).

• Why players want her: Nature has mostly been a support/reaction element; Arcane is the first limited 6-star built as a Nature DPS, and she carries her own Corrosion reaction, so she functions before you have a perfect team.

• Off-rates: Mi Fu and Camille appear in her pool.

• Signature weapon: Type 42: Solemn Phalanx (Arts Unit), on its own rate-up.

Liino (Phase 2) at a Glance

• Banner: "Good Morning From Your Dawnstar" — Version 1.4 Phase 2.

• Rarity / Class / Element: limited 6-star Supporter, Electric element, Polearm weapon.

• Idol/bard kit: Liino is Endfield's take on the Bard subclass. She toggles between a Vocalist Stance (team ATK buffs) and a Cosmovoice Stance (healing + bigger buffs), disabling her own basic attacks while the aura persists.

• Why players want her: a flexible Electric supporter with team-wide buffs and healing tends to hold long-term value across many team compositions.

• Off-rates: Arcane and Camille appear in her pool.

• Signature weapon: Bedazzling Night Debut (Polearm).

Should You Skip Arcane / Liino to Save for the Future?

This is the heart of the guide. The phased structure of 1.4 is actually a gift: Arcane runs the whole first half, so you can pull her, evaluate your roster, and still bank toward Liino — or skip both and aim at Si.

Pity Math You Must Respect

Arknights: Endfield uses a Headhunting (gacha) system with these confirmed thresholds:

• A 6-star is guaranteed by 80 pulls (with a 50/50).

• The featured limited Operator is guaranteed by 120 pulls.

• Pity is banner-bound — partial progress does not carry over when the banner closes.

That last point is the trap. If you start Arcane, you must be able to reach 120 to guarantee her; if you stop at 60, that progress vanishes at phase end.

The "Save for Si" Calculation

Si is expected in Version 1.5, immediately after 1.4. If she is your target, the math is brutal but clear:

• Banking ~120 Oroberyl pulls secures one guaranteed Si.

• If you also want the Hongshan Imperial Guard or Sarkaz Archer later, each future limited is another ~120-pull floor.

• Pulling both Arcane and Liino to guarantee could cost ~240 pulls — pulls that will not return for Si.

The Version 1.4 anniversary hands out free currency you should claim before spending a cent: the "Tribute of Companionship" login gives 3,000 Oroberyl, 5 Basic HH Permits, and a free 6-star Sword (Farsight). Use that free pull power first, then decide whether your real gap is Nature DPS (Arcane), team buffs (Liino), or none of the above (save).

If you need more Oroberyl to either chase Arcane now or stockpile for Si, you can top up through Topuplist and jump to the Arknights: Endfield store for the right pack.

Who Should Still Pull Arcane or Liino

Skipping is not automatic. Pull if:

• Your roster lacks a Nature DPS — Arcane fills the gap most accounts genuinely have.

• Your teams need a flexible Electric supporter — Liino's buffs/healing age well.

• You are a collector or lore-first player — owning Arcane or Liino likely gates personal story chapters (following the Mi Fu and Camille pattern).

Skip guilt-free if:

• Your roster is already deep across every element and neither role is a gap.

• Si is your true target and 120 banked pulls are worth more than a reluctant 1.4 pull.

• You need certainty — Arcane's exact multipliers were unconfirmed at preview; waiting for launch numbers is reasonable.

The smartest move for a future-focused account is often: pull Arcane only if she fills a real hole, then bank everything else for Si. Because Arcane is Phase 1 and Liino is Phase 2, you are never forced into a single all-in decision on day one.

Stock up before the window by buying Oroberyl at Topuplist and visiting the Arknights: Endfield top-up center for bundle value.

Oroberyl & Pull-Planning Reference

• Premium currency: Oroberyl (topped up via Origeometry packs, Monthly Passes, and Chartered HH Permits).

• Free currency: Oroberyl from events/logins, plus Headhunting (HH) Permits from sign-in campaigns.

• Rule: never start a limited banner without a path to 120 pulls. Partial pity is lost at banner close.

• Rule: claim all anniversary freebies before spending real money — they lower your effective cost.

• Rule: prioritize Operators before signature weapons — a new 6-star almost always out-values a weapon banner for most accounts.

When to Expect Each Banner (Roadmap)

This roadmap is the anchor for every "should I skip?" decision. The further out a unit is, the more you gain by banking now — but the less you know about their kit, so avoid over-committing Oroberyl to a unit whose class and element are still unknown.

Don't let the peak pass you by — top up Oroberyl at Topuplist through the Arknights: Endfield recharge page and walk into Version 1.5 with a full pull fund for Si.

Common Saving Mistakes

• Starting a limited banner without a 120-pull path — partial pity evaporates at close.

• Pulling on FOMO — "limited" is a reason to weigh, not a reason to pull a role you don't need.

• Chasing signatures before Operators — a 6-star unit beats a weapon for almost every account.

• Ignoring free anniversary currency — the Tribute of Companionship handouts are real pulls you're leaving on the table.

• Over-saving for unknowns — banking for Si is smart; burning all planning on the Sarkaz Archer (whose kit is unpublished and furthest out) is speculative.

• Assuming teased = imminent — a Future Version Preview unit is typically one to two patches away, not next week.

FAQ

Q: Who are Si, the Hongshan Imperial Guard, and the Sarkaz Archer?
A: They are three upcoming Arknights: Endfield Operators revealed in the Version 1.4 Future Version Preview. Si (the Feranmut Proxy) is expected in Version 1.5; the Hongshan Imperial Guard and the Sarkaz Archer are slated for versions after that.

Q: Is Si available to pull now?
A: No. Si makes her first story appearance in Version 1.4 (in Yinglung Pass) but her banner is expected in Version 1.5.

Q: What is confirmed about the Sarkaz Archer's kit?
A: Only her design and lore are confirmed — purple hair, Sarkaz horns, mechanical gauntlets with blades, aggressive melee, and a dream-walking "collects stories" theme. She resembles Typhon. Class, element, and skills are not yet published.

Q: Should I skip Arcane and Liino to save for Si?
A: If Si is your target and your roster is already balanced, banking ~120 Oroberyl pulls for her is reasonable. Pull Arcane or Liino only if they fill a real gap (Nature DPS or Electric support). Both 1.4 banners are banner-bound, so plan each separately.

Q: How many pulls guarantee a limited Operator?
A: A 6-star is guaranteed within 80 pulls (50/50), and the featured limited Operator within 120 pulls. Pity does not carry between banners.

Q: Where do I get free pulls for Version 1.4?
A: The "Tribute of Companionship" login event gives 3,000 Oroberyl, 5 Basic HH Permits, and a free 6-star Sword (Farsight). Claim these before spending any top-up curren
