Arknights Endfield: Fastest Way To Get Gold Gears (Factory AIC Wuling Guide for End Game Gear)

What to know

  • Gold-rarity gear depends on Xiranite Components, so Wuling is the real “gear gate” for endgame gearing.

  • Forge of the Sky placement is limited (1 by default; 2 after Forge Expansion I), which is why you build around that cap instead of brute-forcing output.

  • Environmental Monitoring in Wuling is a major Stock Bill source; at level 2 it unlocks 3 weekly photo quests worth 250,000 Stock Bills each (750,000/week).

  • A half-capacity Xiranite Component setup is commonly recommended to avoid starving your base of resources needed for power and other lines.


In Arknights: Endfield, Wuling gold gear is less about “one perfect craft” and more about getting the right unlocks and then keeping your factory stable under Forge of the Sky limits. If you set up a clean Xiranite → Xiranite Component loop and pair it with consistent Wuling Stock Bills, you can steadily turn time into gold gear without constantly rebuilding.

Goal What you do Why it matters
Unlock gold gear pipeline Progress story until Wuling systems open and Forge of the Sky becomes available via Wuling AIC plan Forge of the Sky is the entry point to Xiranite-based crafting used for gold gear components.
Start producing Xiranite Build Forge of the Sky and route its outputs into storage/lines Xiranite is a key input for Xiranite Components and Wuling batteries.
Build Xiranite Components Feed Xiranite into a component line (often run at ~50% capacity) Gold gear requires Xiranite Components; half-capacity helps manage scarce Wuling resources under Forge limits.
Secure Stock Bills Use Environmental Monitoring (weekly photo quests) plus your normal region economy loops At level 2, Environmental Monitoring provides up to 750,000 Wuling Stock Bills/week from 3 quests.
Scale carefully Unlock Forge Expansion I if you need more throughput Forge Expansion I allows placing a second Forge of the Sky

How the Wuling gold gear crafting loop works

Gold-rarity gear is tied to Xiranite Components, and those components are built around Xiranite production from the Forge of the Sky. Because you’re limited to one Forge of the Sky by default (two with Forge Expansion I), the fastest “real” method is maximizing uptime and preventing clogs rather than endlessly expanding belts.

A practical rule: treat Xiranite as your bottleneck and design everything downstream (components, storage buffers, routing) so the Forge of the Sky never stalls.

How to unlock the Forge of the Sky quickly

Step 1: Push main story until the Wuling Forge unlock triggers

Forge of the Sky is unlocked through the Wuling AIC Plan when you reach the story mission “The Surging Tide,” which unlocks the Xiranite Forging node.

Step 2: Craft and place your first Forge of the Sky

Forge of the Sky is an AIC building (5×5) and can be crafted using Ferrium Parts x20.

Step 3: Plan around the placement cap from the start

You can only place one Forge of the Sky by default across Wuling AICs, so build your initial factory assuming that limit.

Step 4: Expand only when you have a reason

If you need higher throughput, Forge Expansion I lets you place a second Forge of the Sky—this is your main “scale breakpoint.”

How to set up the fastest Xiranite Component factory

Step 1: Run a half-capacity Xiranite Component line first

A 50% capacity production line is often recommended because Wuling raw materials are limited and Forge of the Sky placement is restricted; it also helps you reserve resources for batteries and other needs.

Step 2: Target a stable “one character per hour” rhythm

A half-capacity setup is described as roughly 1 gear per 15–16 minutes, translating to gold-quality gears for one character per hour under steady operation.

Step 3: Prevent clogging with storage buffers

Forge-of-the-Sky layouts that include storage intake for extra outputs are used specifically to prevent clogging, which keeps Xiranite manufacturing running continuously.

Step 4: Route Xiranite into the right downstream products

Forge of the Sky’s primary use is manufacturing Xiranite for recipes such as LC Wuling Batteries and Xiranite Components, so decide early how much Xiranite you want reserved for power versus components.

How to get Wuling Stock Bills fast for nonstop gold gear crafting

Step 1: Unlock and use Environmental Monitoring

Wuling has an Environmental Monitoring system that provides weekly photo quests that reward large amounts of Stock Bills.

Step 2: Upgrade Environmental Monitoring to level 2 as soon as you can support it

At level 2, Environmental Monitoring unlocks three weekly quests, each rewarding 250,000 Stock Bills (750,000 total per week).

Step 3: Treat Stock Bills as your “crafting permission slip”

Wuling Stock Bills are a regional currency (separate from other regions), and you need Wuling’s version specifically to keep Wuling progression and purchases moving.

Keeping your Wuling gold gear farm running smoothly

The limiting factor is almost always Forge of the Sky uptime under the placement cap, so stability beats sheer size. If your base is constantly short on power or backing up on outputs, scale down to a half-capacity component line until your routing and storage stop clogging.

If you want gold gear fast, rush Wuling’s Forge of the Sky unlock, build a clog-proof Xiranite → Xiranite Component line, and fund it with upgraded Environmental Monitoring Stock Bills. Once your loop is stable, expand only when Forge Expansion I (second Forge) will actually increase sustained output rather than just creating new bottlenecks.
