Arknights: Endfield 1.6 Leaks: Si & Ye Minghui Banners

Arknights: Endfield Version 1.6 is shaping up to be another two-6-star update, if current leaks hold. The headline names are Si in Phase 1 and the Hongshan Imperial Guard, leaked as Ye Minghui, in Phase 2. Both have appeared in official future-version previews, but their banner placement, rarity, classes, elements, and kits remain unconfirmed.

For players planning pulls, the practical question is simple: do you save Oroberyl now, or wait for official Combat Overviews? This breakdown covers the expected schedule, what we know about each Operator, and how to prepare without wasting resources. For broader coverage, see our Arknights: Endfield news hub.

Endfield 1.6 Release Date

Endfield has generally stayed around a six-to-seven-week version cycle. Version 1.5 launched on 2026-09-02, which puts Version 1.6 around 2026-10-15.

That date is an estimate based on the established cadence, not an official announcement. Treat it as a planning window rather than a locked calendar entry.

Endfield 1.6 Banner Overview

The expected lineup currently looks like this:

Phase	Operator	Rarity	Expected Element	Expected Class
Phase 1 (2026-10-15)	Si	6★	Heat	Caster
Phase 2 (2026-11-05)	Ye Minghui	6★	Electric	Vanguard

Both rows are Unconfirmed — subject to change. The Phase 2 date in particular is an estimate derived from the Phase 1 window and typical banner length.

Endfield 1.6 New Characters

Phase 1: Si

Si is currently expected to be the first new 6-star Operator of Version 1.6. Endministrators have already seen her in Endfield's story and future-version previews. She is the Feranmut Proxy associated with Sui and uses Ink Spirits, scrolls, and butterfly-like constructs.

Earlier information reportedly listed Si as Nature, so her Heat element should still be treated cautiously until her official Combat Overview arrives. There is also very little reliable information about her actual combat mechanics right now. Her story abilities heavily feature Ink Spirits and scrolls, but we still do not know how those will translate into her playable kit.

Phase 2: Ye Minghui

The second expected 1.6 Operator is the Hongshan Imperial Guard previously shown in official preview material. Leaks currently identify him as Ye Minghui. He is the blond male Operator seen with a polearm and an Imperial Guard-style design.

Compared with Si, considerably more early kit information has appeared for him. There is an important conflict here: older information described him as Physical, while newer leaks call him an Electric Vanguard. His leaked kit also contains several Physical-related effects, so the final element remains uncertain.

His class being Vanguard is particularly interesting because his leaked mechanics appear heavily tied to Skill Point efficiency and burst preparation. If accurate, that would make him a rotation enabler rather than a pure damage dealer.

Should You Pull?

This section is speculative by necessity. No official rates, pity details, or kit numbers for Version 1.6 have been released.

Pull if…

• You already main a Heat or Caster team and Si's rumored element fits your roster.
• You need a Vanguard with Skill Point utility and Ye Minghui's leaked role matches your playstyle.
• You are a collector who wants both 6-stars regardless of meta placement.

Skip if…

• You are saving for a confirmed rerun or a future version with officially revealed kits.
• Your account already covers these roles comfortably.
• You prefer to wait for Combat Overviews before committing Oroberyl.

Save for…

• Official Version 1.6 announcements and Combat Overviews.
• Any confirmed rerun banners that may run alongside 1.6.
• Future versions where kit details are fully verified.

Preparation Checklist

• Do not pre-farm character-specific materials based on leaks. Element and class conflicts for both Si and Ye Minghui make early farming risky.
• Save Oroberyl if you are interested in either banner. Currency is the only resource that transfers cleanly between plans.
• Track official channels for Combat Overviews, which typically arrive closer to the banner window.
• Check your pity status on the current banner before Version 1.6 arrives, so you know your starting position.
• Review your roster for existing Heat, Electric, Caster, and Vanguard coverage.

Teams & Synergies

Not stated in official materials. Neither Si nor Ye Minghui has a confirmed kit, so team-building advice would be pure speculation at this stage.

For context on how Endfield team comps are currently built, see our Rossi best team comps guide. It covers Physical and Heat synergy logic that may become relevant if Si's rumored element holds.

Community Signals

Official streams and notes have not yet detailed Version 1.6 banners. The only confirmed points are that both characters have appeared in future-version previews. Everything else, including banner order, rarity, and kits, remains Unconfirmed — subject to change.

For past version context, our 1.4 leaks breakdown and 1.1 update overview show how Endfield has handled two-6-star patches before.

Conclusion

Version 1.6 could deliver two new 6-star Operators in Si and Ye Minghui, but almost everything beyond their preview appearances is unconfirmed. The smart play is to save Oroberyl, avoid leak-based farming, and wait for official Combat Overviews before deciding.
