Arknights: Endfield is heading into one of its busiest updates yet, and Version 1.3 is not simply adding a new area. It is also widening the game’s endgame layer, introducing two 6-star Operators, and bringing long-requested system improvements into the factory side of the experience.
The update is titled “Sketches of Lost Heirlooms” and is set to arrive on 5 June 2026. Alongside its combat additions, it marks the debut of Contingency Contract in Endfield, a challenge mode long associated with Arknights and now being brought into the new game’s progression loop.
A new region with stronger story ties
The most eye-catching expansion in Version 1.3 is Sword Vault Dale, a new sub-region positioned as a major focal point for the update. The area is described as an ancient place that has resurfaced after Wuling’s efforts to clear the Erosion Tide.
For longtime Arknights players, Sword Vault Dale also carries a recognizable connection to Chi Xiao. That detail gives the new region more weight than a simple map expansion, since it links Endfield more tightly to the wider lore of the franchise.
Gryphline appears to be using the location as both an exploration space and a narrative bridge. That approach makes the new zone feel important not only for progression, but also for players who follow the broader universe closely.
Mi Fu brings fast-paced physical pressure
Among the new Operators, Mi Fu stands out as a 6-star Physical Guard and the captain of the Wuling Watch patrol. He is framed as an aggressive burst fighter with high mobility, which sets him apart from more static frontline options.
His combat style centers on chaining up to four basic attacks before moving into Battle Skill sequences. His main skill, Qingbo Triplex, is split into three movements: Cloudtrapper pulls nearby enemies or closes distance to faraway targets, Trail and Mangle applies Crush, and World Splitter delivers a powerful frontal slash with strong damage.
Mi Fu’s kit also relies on vulnerability stacking. Once an enemy reaches three stacks, his combo skill triggers automatically and applies physical susceptibility before looping the flow back to Trail and Mangle.
His Ultimate, Pile of No Mercy, continues that rhythm by launching a target upward and slamming it down for heavy physical damage. The sequence keeps his offense moving and reinforces his role as a relentless burst attacker.
Camille arrives later with a different combat identity
Phase 2 adds another 6-star Operator in Camille, who enters as a Heat Vanguard. He is also notable as the first male 6-star in Endfield and the game’s first limited Heat Vanguard.
Camille’s background expands the cast in a different direction. He is presented as a Sarkaz vampire and a Blood Hunter from the Seš’qa region, giving his arrival a distinct character angle beyond his battle role.
His solo event, Danse Macabre, is framed around a criminal investigation that begins with an anonymous blood sample. That setup adds a separate narrative thread to the version update without shifting attention away from combat content.
In battle, Camille uses Firefang Vesperwings as a summon. The unit deals heat damage while spreading heat infliction, weakness, and heat susceptibility around it, and it automatically shifts to the nearest remaining target when an enemy is defeated.
His combo skill activates when heat infliction is consumed. That triggers a fast dash, extra heat damage, and SP recovery, which helps him keep pressure on the field without breaking tempo.
Endgame and factory changes round out the update
Version 1.3 also brings Contingency Contract into Endfield for the first time. Its arrival adds a high-difficulty endgame option to the game’s structure and gives experienced players another layer of challenge to pursue.
Outside combat, the update includes several quality-of-life improvements for factory management. These changes include bulk equipment forging, bulk weapon dismantling, and lock management, which helps protect pinned gear from being removed during mass operations.
Taken together, Sword Vault Dale, the two 6-star Operators, the new challenge mode, and the system upgrades make Version 1.3 feel unusually dense. With Version 1.2’s banner still running until before 5 June, Endfield is lining up a major content shift as it moves into this next stage.
