What to know
- The Valley Pass Amethyst mineral bed is a 2-node bed on a high plateau that’s otherwise difficult to access early.
- The practical route is: power an Electric Nexus, use the updraft to reach the plateau, then place and power mining infrastructure.
- A pre-built zipline pylon to the plateau can skip some traversal, but power is still required for mining.
- Valley Pass contains 2 Amethyst Ore mining spots in this bed, so planning for two rigs helps.
In Arknights: Endfield, getting this done smoothly is less about fighting and more about setting up a working power path, because the plateau access and the mining rigs both depend on electricity.
Reference table: location and requirements
| Category | Details |
|---|---|
| Area | Valley IV → Valley Pass (overlooking Abandoned Trail / near Valley Transfer region) |
| What’s being powered | Electric Nexus (to activate the updraft), then Electric Pylon coverage for the rigs |
| Mineral bed size | 2 mining nodes (Amethyst) |
| Core build pieces | Electric Mining Rig (per node), Electric Pylons (to deliver power), relay tower may be used depending on spacing |
| Optional shortcut | If a zipline pylon is already placed that goes straight up to the plateau, reaching the bed is faster |
How to power the Amethyst mineral bed and start automated mining
Once on the plateau, the goal changes from “reach it” to “make it run unattended.”
Step 1
Locate both Amethyst mining nodes on the plateau (this bed has two spots).
Step 2
Place an Electric Mining Rig on each node (or at least one, if only one rig is available).
Step 3
Place an Electric Pylon near the rigs so they are clearly within its supply range.
Step 4
If the pylon itself is unpowered, extend power to it using the same method used for the Nexus: build a continuous powered link from an existing powered point to the plateau pylon (adding pylons/relays as needed until the connection holds).
Step 5
Confirm each mining rig is active; if a rig sits idle, the most common cause is that it’s outside pylon range or the pylon chain is not truly connected.
Step 6
Let the rigs run and verify that mining output is being routed properly to storage (Depot/production chain), since the whole point of this bed is automation.
Troubleshooting that matches what usually goes wrong here
| Symptom | Likely cause | Practical fix |
|---|---|---|
| Updraft never appears | Electric Nexus is still not powered | Re-check the power chain into the Nexus; ensure the link is continuous |
| Reached plateau but rigs won’t run | Rigs have no powered pylon coverage | Move the pylon closer or add another pylon to bring the rigs into range |
| Pylon placed but still “dead” | Power chain breaks due to distance/spacing | Add intermediate pylons and/or a relay tower to bridge the gap |
| Only one node is mining | Only one rig placed, or second node missed | Place a second rig and confirm it sits correctly on the second node |
Practical build plan for a 2-node Amethyst bed
Because Valley Pass Amethyst is a two-node bed, it helps to treat it as a small “outpost package” instead of a single-objective task.
| Target | Recommended minimum | Notes |
|---|---|---|
| Active mining nodes | 2 | Fully utilizes the bed |
| Electric Mining Rigs | 2 | One per node |
| Electric Pylons | Enough to form a continuous chain | Quantity varies with the route; expect several |
| Relay tower | Optional | Useful if pylon spacing is tight or the plateau link is long |
Getting the Valley Pass Amethyst bed running reliably
Once the Electric Nexus is powered and the updraft provides access, the remaining work is standard automation: rigs on both nodes, a powered pylon within range, and a continuous power link back to an existing powered point. After that, the Amethyst bed functions as a stable automated resource source instead of a one-time pickup spot.
