What to know
- Gloomvale unlocks through the main story quest Silent Grove
- A sealed gate and mandatory combat encounter block initial access
- The region introduces Gloom Accumulation, a fog-based debuff
- Exploration rewards include rare materials and an optional elite boss
Gloomvale is a mid-game region in Arknights Endfield, designed to push players beyond basic combat and into environmental awareness and route planning. You cannot access Gloomvale freely early in the game. Its unlock is tied directly to story progression.
As you advance through the main campaign, you’ll eventually receive the quest Silent Grove. This quest leads you toward a fog-heavy valley that is clearly marked as inaccessible at first. At the entrance, a large sealed gate blocks progression, preventing entry until the quest objectives are met.
Interacting with a nearby control console triggers a mandatory combat encounter. This fight serves as an introduction to the type of pressure you’ll face inside Gloomvale, combining environmental hazards with aggressive enemies. Once the encounter is completed, the gate opens permanently, officially unlocking Gloomvale on the world map and allowing free travel in and out of the region.

What to focus on after entering Gloomvale
The moment you step into Gloomvale, the atmosphere shifts. Visibility drops sharply, ambient sounds dull, and fog blankets most of the terrain. Unlike earlier regions, moving forward aggressively is punished, not rewarded.
Your first major task inside Gloomvale is activating Rift Devices. These devices act as fast-travel points while also revealing large sections of the map. More importantly, they help establish safe traversal routes through the valley. Each Rift Device you activate reduces the need to cross long fog-filled paths repeatedly, making later objectives far more manageable.
Players who delay activating Rift Devices often struggle with unnecessary debuff buildup and inefficient backtracking. Early stabilization of the region is key to long-term success.
Gloom Accumulation and how fog changes exploration
The defining mechanic of Gloomvale is Gloom Accumulation. Remaining inside dense fog causes this debuff to gradually build on your squad, reducing combat performance and survivability over time. The danger isn’t immediate, but it compounds quickly during prolonged exploration or extended fights.
To counter this, the region introduces Purification Beacons. These devices clear fog in a limited radius, creating safe zones where Gloom Accumulation dissipates. Proper beacon placement allows you to rest, fight, and gather resources without constantly retreating.
In Gloomvale, environmental control is just as important as combat ability. Managing fog effectively determines how far and how safely you can explore.
Combat encounters and Blighted enemies
Enemies in Gloomvale are noticeably more durable and punishing. The Blighted enemy types native to the region are designed to exploit long engagements, especially when fought inside fog-heavy areas.
Elemental reactions become especially valuable here. Efficient reaction chaining shortens fights, reducing exposure to Gloom Accumulation. Balanced squads with crowd control and sustained damage tend to outperform pure burst compositions in this region.
Combat pacing slows down intentionally, reinforcing the idea that Gloomvale is not meant to be rushed. Smart positioning and ability timing matter more than raw damage.
Resource collection and progression importance
Gloomvale is a critical resource hub for mid-to-late game progression. Rare ore deposits and biological samples found here are required for advanced crafting and upgrades. Many of these materials do not appear in earlier regions, making Gloomvale essential rather than optional.
Resource nodes are frequently placed in fog-heavy zones or along elevated terrain. Clearing fog with Purification Beacons not only improves survivability but also makes resource farming significantly more efficient.
Verticality plays a major role in Gloomvale’s design. Cliffs, broken platforms, and layered terrain conceal hidden chests and alternate routes that are easy to miss if you stick to ground-level paths.
Using climbing and gliding effectively often allows you to avoid fog-dense areas entirely, creating safer traversal options. Many high-value chests are deliberately placed above the fog line, rewarding players who explore upward rather than forward.
Gloomvale as a Wuling city
The Silent Grove quest marks a turning point in Arknights Endfield. From this point forward, the game begins demanding environmental awareness, route planning, and fog management, not just combat efficiency.
Once properly stabilized, Gloomvale transforms from an oppressive zone into one of the most valuable regions in the game for both resources and progression.
Unlocking Gloomvale through Silent Grove is straightforward, but mastering the region takes preparation. By prioritizing Rift Devices, managing fog with Purification Beacons, and leveraging vertical exploration, you can turn Gloomvale from a constant threat into a powerful progression hub.
