On May 22, 2026, at 19:30 (UTC+8), Arknights: Endfield aired its Version 1.3 preview special program, "Relics Sketch," officially confirming that the update will go live on June 5.
This marks the most significant update since the game's launch. The long-awaited endgame mode, Emergency Contract, makes its official debut, signaling a new era for high-difficulty challenge content. Two new operators, Mihan and Camille, are being introduced in stages, a brand-new map called Sword-Hidden River is opening for exploration, and a number of highly requested quality-of-life improvements are also rolling out with this update.
This article summarizes all the key highlights from the livestream, covering new operator mechanics, banner schedules, the new map, event calendar, quality improvements, and a sneak peek at Version 1.4 — so you can get a head start on planning for the new version.
Arknights Endfield Version 1.3 Release Date & Update Schedule
The official title of Arknights: Endfield Version 1.3 is "Sketches of Lost Heirlooms". Here's a full breakdown of all key dates:
| Milestone | Date | Time (UTC+8) |
| Version Preview Livestream | May 22, 2026 | 19:30 |
| Version Launch (Phase 1) | June 5, 2026 | 12:00 |
| Phase 2 Goes Live (Camille Banner) | June 26, 2026 | 12:00 |
Phase 1 Banner — Mi Fu, 6★ Physical Guard
Version 1.3 introduces two brand-new 6-star Operators, each arriving in a separate phase. Taking center stage in Phase 1 is Mi Fu, a Physical Guard whose banner goes live alongside the version launch on June 5.
Mi Fu is the featured Operator of Phase 1, playing as a Physical Guard built around rapid-fire Battle Skill chains. Her Battle Skill progresses through three distinct stages: pulling enemies together, consuming Vulnerability stacks to unleash a burst of damage, and then driving up the Stagger bar. Her Ultimate applies Vulnerability to enemies, setting the table for her next skill loop.
The overall flow is fast-paced and satisfying to execute, and she slots in naturally alongside teams that already have a Physical Vulnerability-focused setup.
Her signature weapon, Amaranthine Tassel, is a Greatsword that boosts Strength as its main stat and Attack as a secondary stat — a natural fit for Mi Fu's Vulnerability-fueled burst playstyle.
Phase 2 Banner — Camille, 6★ Heat Vanguard
Camille is without a doubt the most anticipated Operator of this version. As Arknights: Endfield's first limited male 6-star, his arrival has sparked widespread discussion across the community.
His core role is that of a team-support Vanguard, built around SP generation and Heat Infliction stacking. His Battle Skill continuously applies Heat Infliction and Heat Susceptibility to enemies; once those stacks are consumed, his Combo Skill triggers, dealing Heat DMG while restoring SP for the entire team.
His Ultimate applies Heat Infliction across the battlefield and activates Hunt Mode — while active, his next Battle Skill counts as a Combo Skill without consuming SP, effectively delivering a second wave of SP recovery. For teams already running Laevatain, Camille is the missing piece that meaningfully tightens the entire rotation loop.
His signature weapon, Blessing of Lustrous Carmine, is a Polearm that boosts Agility as its main stat and Heat DMG as a secondary stat — a natural fit for Camille's Heat-focused support kit.
Version 1.3 New Weapons
Version 1.3 introduces four new 6-star weapons in total, available through two separate acquisition channels: signature weapon banners tied to their respective Operators, and the standard pool, which can be pulled from regular recruitment.
Version 1.3 New Game Modes
Version 1.3 introduces three new game modes, with Contingency Contract being the most anticipated addition of the update.
Contingency Contract
Contingency Contract is a mode carried over from the original Arknights, and has been the most requested endgame challenge by Endfield players since launch. You can stack difficulty modifiers to build your own contract — options include disabling dodge, making the Ultimate only effective on its first use, and having enemies leave persistent damage zones upon death.
The reward structure is worth highlighting: core material rewards are concentrated at lower difficulty tiers, meaning casual players can claim all meaningful rewards without stacking modifiers to the limit. Higher difficulty tiers exist purely for the challenge — they're not tied to additional rewards.
Trial of Swordmancy
A permanent combat mode opening on June 12. Similar to Umbral Monument, but with a key difference: you can customize the enemy lineup yourself, making it ideal for testing specific Operators in practice scenarios or experimenting with self-imposed difficulty combinations.
Crisis Fragment
A permanent challenge mode that unlocks after completing the main quest "Deep Steel Deposits." Specific mechanics will be confirmed once the version goes live.
New Area — Sword Vault Dale
Sword Vault Dale is the new explorable sub-region added in Version 1.3. Once swallowed by the Corruption tide, it has resurfaced as Wuling's purification efforts push forward.
This is the game's first map built around a wuxia/xianxia aesthetic, with ancient Yan civilization ruins and Sword Sect pillars woven throughout — a visual identity that stands in sharp contrast to Wuling's industrial and technological look. Players familiar with the original Arknights will find narrative Easter eggs tied to Chi Xiao here, deepening the lore connections between the two titles.
Both Mi Fu's and Camille's personal story quests are set in Sword Vault Dale. Exploration content includes new collectibles, area development nodes, and a variety of puzzles tied to the "Explore Sword Vault Dale" guided event.
Weapon banners and character banners have separate pity systems. Pulling for weapons does not affect your character pity, so you’ll need to plan and track your resources separately
Version 1.3 Events Schedule
Version 1.3 features a wide variety of events spanning the full duration of the update, from main story content to time-limited challenges. Login events run separately for each of the two banner phases — make sure to log in every day from the start of each phase so you don't miss out on any free recruitment tickets.
All of the above events are time-limited and cannot be claimed retroactively once they've ended. Of particular note are Mi Fu's and Camille's personal story quests — A Handful of Reflections and Dance of Death respectively — which are the primary way to learn about each Operator's backstory. These are worth prioritizing early.
Quality of Life Improvements in Version 1.3
Gear & Weapons
- Gear can now be crafted in bulk, significantly cutting down the time spent processing pieces one by one.
- Weapons can now be batch-dismantled, and locking management has been streamlined accordingly.
- Essence matching has been improved: once you select a target weapon, compatible Essences are automatically flagged and locked to prevent accidental dismantling.
AIC
- Furnace blockages are now resolved automatically when multiple recipes jam at once, eliminating the need for manual intervention.
- A Backup Power feature has been added, giving you access to temporary unlimited power that you can activate whenever needed.
- Xiranite Pylons and Xiranite Relays inside and outside the Wuling region can now be cross-connected across zone boundaries.
Combat
- Off-screen attack warnings have been strengthened, giving you a wider reaction window to respond to incoming threats.
- A "Version Priority" tag has been added to the mission list, helping you quickly identify which missions to focus on in the current version.
Controls & UI
- Mouse and controller switching logic has been improved, with seamless hot-swapping now supported.
- A Region Overview button has been added to the main interface of the Regional Development system.
- After visiting a friend's base, you can now return directly to your own OMV Dijang with a single button.
Version 1.4 Teasers — Arcane, New Maps & AIC Overhaul
Toward the end of the livestream, Hypergryph shared a first look at what's coming in Version 1.4.
New Operator
A teaser for an unidentified idol-type Operator was shown, with no details revealed on class, element, or kit. Full information is expected at the official Version 1.4 preview stream.
New Maps
Version 1.4 will add two new explorable maps. Names and details have not yet been disclosed.
AIC Overhaul
Version 1.4 will bring the largest AIC update the game has seen to date, introducing a brand-new gas product category, a large number of new Xiranite and Ferrium recipes and facilities, and additional mining nodes. If you're heavily invested in the factory side of the game, it's worth taking stock of your current production lines now and clearing space to accommodate the expansion.
We also recommend saving up enough Weapon Essences during 1.3 to prepare for the Arcane banner coming in Version 1.4.
How to Get Free Pulls in Arknights: Endfield Version 1.3
The two login events are the most reliable source of free pulls this version, offering a combined total of 10 pulls.
Make sure to log in every day starting from the first day of each phase so you don't miss a single one.
How to Watch the Version 1.3 Dev Log
The Dev Log is released as a pre-recorded video, not a live broadcast—so you can watch it anytime.
YouTube: Search the official Arknights: Endfield channel, look for “Dev Log Program 1.1”
Twitter / X: Posted on the official account @AKEndfield with a video link
Bilibili: Chinese-subtitled version available on the official account
Recommendation: Watch it in full before the update goes live—it’ll help you better understand new mechanics and map design, and plan your progression more efficiently once 1.1 drops.

FAQ
How does the pity system work in Arknights: Endfield?
Arknights: Endfield uses an 80-pull soft pity that guarantees a 6-star, with a 50/50 chance it's the featured Operator. Lose the 50/50, and your next 6-star is guaranteed to be the featured character. A 120-pull hard pity skips the 50/50 entirely but resets when the banner ends and does not carry over.
Do limited Operators come back in Arknights: Endfield?
Yes. After a limited Operator's banner ends, they remain available as an off-rate 6-star in the next two standard Chartered Headhunting Banners. Odds are lower than during their featured run, so pulling during the debut banner is always recommended if you have the resources.
What is the difference between Phase 1 and Phase 2 banners?
Each version is split into two phases, each featuring a different limited Operator. Phase 1 launches alongside the version update, and Phase 2 opens roughly three weeks later. Pity does not carry between the two phases, so plan your resources separately for each banner.
Does weapon banner pity carry over between versions?
No. Weapon banner pity resets when the banner ends and does not carry over to the next version. Always factor this in before spending Arsenal Tickets — if you're close to pity on a weapon banner, it's generally worth finishing rather than letting the progress reset.
Should I pull for signature weapons or save for the next Operator?
In most cases, securing the Operator should come first. Signature weapons typically offer a meaningful but not decisive upgrade — most content is clearable with standard pool or Protocol Pass weapons. Only pull for a signature weapon if you have surplus resources after guaranteeing the Operator and are confident you won't need those pulls for an upcoming banner.
