How to Use Turrets for Energy Alluvium Battles in Arknights Endfield

What to know

• Turrets must be unlocked through blueprints and crafted before use
• They require power, either from batteries or nearby power structures
• Turrets excel in Energy Alluvium encounters, including severe variants
• You can retrieve and reuse turrets after fights, making them resource-efficient

In Arknights Endfield, turrets are not just optional gadgets—they are one of the strongest tools for controlling open-world encounters. Many players overlook them early on, assuming they’re only for niche base-defense scenarios. In reality, turrets can trivialize some of the game’s hardest Energy Alluvium battles, letting you clear content with minimal effort and risk once you understand how the system works.

This guide explains how to unlock turrets, how to power and deploy them correctly, and why they are so effective for both one-time and repeatable open-world challenges.

How turret unlocking works in Arknights: Endfield

Turrets are not available by default. You must unlock them through blueprints, just like other advanced deployable structures. These blueprints are typically found through exploration, progression milestones, or specific content rewards tied to base building and open-world systems.

Once you obtain a blueprint—such as the Gun Tower or other defensive structures—it becomes permanently available in your crafting list. This is important, because turrets are not consumable unlocks. After the blueprint is obtained, you can craft as many turrets as you want, as long as you have the materials.

Crafting turrets requires common but meaningful resources, including processed metals and plants. Relay Towers and Electric Pylons, which are often used alongside turrets, also require materials, so it’s wise to stockpile before committing to a turret-heavy strategy.

Crafting turrets and preparing your inventory

After unlocking the blueprint, turrets are crafted through the standard crafting system. Crafted turrets go into your inventory, not directly into the world. This is a crucial detail, because it means turret usage is entirely player-controlled. You decide when and where to deploy them.

Before heading into any serious open-world fight—especially Energy Alluvium encounters—you should manually check that turrets are in your inventory. Forgetting this step is the most common reason players think turrets “don’t work.”

In addition to the turrets themselves, you also need to plan for power. Turrets do nothing unless powered, and this leads into the most important part of using them correctly.

Powering turrets: the system most players misunderstand

Turrets require an external power source to function. There are three main ways to supply power, and understanding them makes or breaks the strategy.

The first option is using Relay Towers and Electric Pylons. These structures transmit power wirelessly within a certain radius. If a turret is placed within range of an active power structure, it will immediately turn on once combat begins. This method is reliable, but it requires more setup and materials.

The second option—and the most flexible for open-world combat—is using batteries. Batteries can be carried in your inventory and inserted directly into turrets after placement. This allows you to deploy turrets anywhere, even far from existing infrastructure. For Energy Alluvium fights in remote locations, batteries are often the best solution.

The third option is combining both systems, using power structures for coverage and batteries as backups. This is especially useful in larger combat zones.

Deploying turrets correctly in the open world

Turret placement is where strategy really comes into play. Turrets cannot be placed directly next to each other. The game enforces a small spacing requirement, meaning you must leave a visible gap between placements. This prevents stacking them in a single point but encourages area coverage instead.

When placing turrets around an Energy Alluvium zone, you want overlapping fields of fire. Spread them around the perimeter or at choke points so enemies entering the area are immediately targeted from multiple angles.

Once placed and powered, turrets activate automatically when the crisis or encounter begins. There is no manual firing or targeting required. As soon as enemies spawn, turrets begin attacking.

Why turrets are so powerful in Energy Alluvium encounters

Energy Alluvium content is where turrets truly shine. There are two main types of Alluviums, and turrets work exceptionally well in both.

The blue “Handle Crisis” Alluviums are one-time encounters. Once completed, they disappear permanently. Turrets can trivialize these fights, letting you clear them quickly without burning healing items or stamina.

Severe Alluviums are different. These encounters are repeatable, cost sanity, and are used primarily to farm essences. They are also significantly harder, often overwhelming players with enemy density or high-level mobs. This is exactly where turrets become game-changing.

With multiple turrets deployed and powered, enemies are stunned, distracted, and damaged continuously. You can often stand back and do nothing while the turrets clear the encounter, even at higher difficulty levels.

Crowd control, stun, and distraction

Not all turrets are purely damage-focused. Some, such as sonic or utility towers, apply stun or disruption effects. These effects are incredibly valuable, because they stop enemies from reaching you or interrupt dangerous attacks.

Even when turrets don’t outright kill enemies, they act as distractions. Enemies often target turrets instead of you, reducing incoming pressure and giving you complete control of the battlefield.

This combination of damage, stun, and aggro manipulation is why turret setups remain effective well into higher-level content.

Retrieving and reusing turrets after combat

One of the biggest advantages of turrets in Arknights: Endfield is that they are not consumed on use. After the battle ends, you can simply stash them. Stashing returns the turret to your inventory, along with any remaining batteries that were inserted.

This makes turret strategies extremely resource-efficient. You are not burning items every time you use them—you are investing once and reusing indefinitely.

For players worried about material costs, this single mechanic alone makes turrets worth prioritizing.

Permanent turret setups for farming

Some Energy Alluviums are permanent fixtures in the world. If you place turrets near these Alluviums and leave them there, they will remain in place. This allows you to return later and farm the same encounter repeatedly with minimal setup.

This is especially effective for essence farming. Once a turret network is established, future runs can be completed in minutes with almost no effort.

Using essence boosts alongside turrets

For severe Alluviums, you can apply specific essence boosts before starting the encounter. When combined with turrets, these boosts push efficiency even further. Enemies melt faster, turrets survive longer, and the overall risk drops close to zero.

This synergy is one of the reasons experienced players rely heavily on turrets for late-game farming.

Alluvium as a Stock Bills farming resource

Turrets are not a gimmick or a niche system—they are one of the strongest tools available for open-world combat in Arknights: Endfield. Once unlocked and crafted, they provide crowd control, sustained damage, and battlefield control with almost no downside.

If you are struggling with Energy Alluviums, burning too many resources, or simply want a more relaxed way to clear content, learning how to use turrets properly changes the entire experience. Bring turrets, bring power, place them smartly, and let the game play itself.
