Arknights: Endfield Region Guide: Valley IV to Landbreakers

Exploring Talos-II in Arknights: Endfield means moving through named regions rather than a single open field, and each zone gates the next with combat encounters, environmental threats, and exploration checks. This Arknights: Endfield region guide walks through Valley IV, the Blight corruption layers, Ankhor stabiliser fights, the Aggeloi frontier, and the Landbreakers rim in the order most players actually clear them. , and exploration checks. This Arknights: Endfield region guide walks through Valley IV, the Blight corruption layers, Ankhor stabiliser fights, the Aggeloi frontier, and the Landbreakers rim in the order most players actually clear them, pairing each step with the objective markers and node layouts shown on our Arknights Endfield interactive map so you can plan routes, track rare-resource spawns, and avoid backtracking through already-purified zones.

How Regions Connect on Talos-II

Talos-II is split into named regions grouped by continent, biome, and threat level. The Valley IV starting zone covers The Hub, Valley Pass, Aburrey Quarry, Originium Science Park, Origin Lodespring, and Power Plateau; the OMV Dijiang ship interior adds the Growth Chamber, Manufacturing Cabin, and Reception Room; and the Wuling expansion layers in Jingyu Valley, Wuling City, Qingbo Stockade, the Marker Stone Test Area, Sword Vault Dale, Yinglung Pass, and the North Wuling Exclusion Zone. The Aggeloi frontier and Landbreakers rim sit further out, which is where the story pushes once Wuling is stable.

The reason the order matters: each region unlocks new ore types for the AIC, and the factory line cannot upgrade beyond a tier until the matching ore is reachable. Players trying to push base production without clearing the next map first hit a hard ceiling on gear quality. A solid early-game plan should follow the regions in roughly the order above, because the level brackets line up with the gear drops you can craft.

Valley IV: The Starting Region and Valley Pass

Valley IV is where every operator drops into Talos-II, and the arknights endfield valley no 4 guide basics live here. The Hub anchors fast travel, the AIC drops near Valley Pass, and Aburrey Quarry is the first combat sandbox where you learn how a four-operator squad shares three skill gauges. Enemies are mostly weak Blight-corrupted drones, so the combat loop is forgiving while the systems sink in.

Sub-areas Worth Clearing First

The Hub and Valley Pass are tutorial-paced. The real time sinks are Aburrey Quarry (ore node #1) and the Originium Science Park puzzle chain, which awards the first batch of T-Creds and a small Oroberyl payout. Origin Lodespring is a water-feature exploration area with hidden chests, and Power Plateau sits above the rest of the map and gates the OMV Dijiang ship interior.

The exploration loop inside Valley IV is mostly about turning on the AIC, placing a mining outpost on the Aburrey Quarry node, and pushing the Originium Science Park quest to unlock the OMV Dijiang shuttle. Once that shuttle is active, the next continent becomes reachable and the real grind begins.

Wuling: Cryo Enemies and the Marker Stone Test Area

Wuling is the second major continent on Talos-II and the first one that punishes under-leveled squads. Enemies here lean Cryo element with high-damage ranged casters in the Sword Vault Dale and shielded bruisers in Qingbo Stockade. The Marker Stone Test Area is a combat gate with multiple wave-based rooms that drop some of the best T3 crafting materials on the Wuling side of the map.

The Cryo roster matters more than usual on Wuling because the casters in Sword Vault Dale apply Brittle stacks that multiply incoming Physical damage. Bringing a Heat-element striker like Ember or a strong Physical main DPS makes those fights dramatically shorter. If the squad lacks either, expect a longer clear because the Cryo shields regenerate between waves.

Aggeloi Frontier: First Real Corruption Clusters

Aggeloi sits on the edge of the Wuling expansion and is the first map where Blight corruption becomes a constant presence rather than an occasional hazard. Terrain deforms, mobs spawn in waves without an obvious trigger, and the map's vertical layering creates kill boxes that punish squads without a frontline defender. The Aggeloi Causeway is the main corridor; the Aggeloi Sieve is a side area with elite enemies and an exploration chest cluster.

The Aggeloi frontier is also where the arknights endfield aggeloi guide path starts to overlap with the arknights endfield blight guide, because the map is one long Blight zone with a few safe pockets. Operators with Heat damage clear faster because Blight shields are weak to that element, and a Defender with a guard uptime skill keeps the squad planted during the longer wave arenas. The Aggeloi Sieve is the single hardest sub-area until the Landbreakers rim opens.

Landbreakers Rim: Where Ankhor Spawns Constantly

The Landbreakers rim is the outermost combat zone in the current Talos-II region set, and it exists primarily to host the densest cluster of Ankhor stabiliser units in the game. Ankhor fights are the actual reason players push the frontier outward: each one cleared grants access to new ore veins, an Essence drop that powers the arknights endfield ankhor guide crafting loop, and a fast travel node that links back to the Wuling City hub.

The arknights endfield landbreakers guide rule of thumb is to bring a squad that can push the imbalance window open early, because every Ankhor stabiliser has a stagger phase that begins after a fixed damage threshold. Skipping that phase means a much longer fight, and the rim's mob density means a single Ankhor pull usually pulls two or three stragglers with it. The single biggest mistake in the Landbreakers rim is treating it like a farming run: the gear payoff only shows up if the squad is strong enough to clear Ankhor in under two minutes, otherwise the per-hour Essence rate drops below what a more casual Wuling farm already delivers.

Blight and Ankhor: How Exploration Progresses the Story

Exploration on Talos-II is structured around cleaning up corrupted zones, and the two systems to understand are Blight and Ankhor. Blight is the environmental corruption that distorts terrain and spawns anomalous phenomena; Ankhor units are the stabilised threat markers that need to be cleared before a region is considered secure. Pushing the frontier outward is what unlocks new ore types for the AIC, so exploration and factory progression are two ends of the same loop rather than separate activities.

The two systems layer: clearing a Blight pocket reveals the Ankhor that spawned inside it, and clearing that Ankhor then unlocks the fast travel node tied to the region. That is the loop that drives the entire mid-game, and it is the same loop that the Game8's Endfield page on Version 1.5 Release Date confirms ties the AIC upgrade path to the exploration path. Players who try to push factory upgrades without first pushing the map usually hit the gear cap that the arknights endfield blight guide framing describes: the next ore is sitting behind an Ankhor they cannot yet clear, which is why pushing the frontier and pushing the factory in parallel is the only way to avoid a hard stop.

Frequently Asked Questions

What level should I be before leaving Valley IV?

Most players clear the full Valley IV region between operator levels 1 and 20, and that bracket is the soft requirement for the OMV Dijiang shuttle to spawn. Trying to enter Wuling below level 25 means longer Cryo caster fights and a low T2 drop rate, which the Game8 beginner progression guide flags as the most common early progression stall.

How do Blight and Ankhor relate to each other?

Blight is the environmental corruption that warps terrain and spawns anomalous mobs, while Ankhor units are the stabilised elites that gate region completion. Clearing a Blight pocket usually reveals the Ankhor hiding inside it, and clearing that Ankhor then unlocks the fast travel node tied to the area, as described in the Game8 exploration and threats overview.

Which element is best for Aggeloi and Landbreakers?

Heat damage is the strongest counter to Blight shields in Aggeloi, and a Heat DPS plus a Defender frontliner is the recommended core for the Landbreakers rim. Cryo casters in Sword Vault Dale punish Physical-only squads, so mixing in a Heat striker or a Physical main DPS keeps the Wuling-to-Aggeloi transition smooth without swapping the whole roster.

What is the fastest way to reach the Landbreakers rim?

The path is Valley IV → OMV Dijiang → Wuling → Aggeloi → Landbreakers, with each region's fast travel node unlocking the next zone. The Aggeloi Causeway is the only direct corridor to the Landbreakers Hollow entrance, so clearing that sub-area first is the single biggest shortcut to skipping the long Outer Talos scrub approach.

Do exploration chests respawn, or is it a one-time clear?

Standard exploration chests are one-time per account, but Blight-clear rewards, Ankhor Essence drops, and T3 ore nodes reset on a weekly rotation. That weekly reset is the reason most players cycle Aggeloi and Landbreakers runs after the first clear, because the chest payout runs out but the material income does not.
