Arknights Endfield: Amethyst Parts Farming Location, Crafting, and Use Guide

What to know

• You must first mine Amethyst Ore in early Hub areas such as near Bridge Approach before you can make Amethyst Parts.​

• Amethyst Ore is refined into Amethyst Fiber using a Refining Unit, then turned into Amethyst Parts in a Fitting Unit at your AIC.

• These parts are key ingredients for Industrial Explosives and some construction tasks like repairing structures, so you will need several pieces.​

• Progressing main story and AIC research unlocks the necessary industry units; without them, you can only stockpile ore for later use.

---

Once you start exploring the Hub and unlocking base facilities, you quickly run into quests and objectives that ask for Amethyst Parts, which forces you to learn the ore-processing chain in the Automated Industry Complex.

Amethyst Parts in Arknights: Endfield are crafted in your AIC by processing Amethyst Ore into Amethyst Fiber, then into Amethyst Parts via the Fitting Unit.

Locations involved in Amethyst-related activities

Most early interactions with Amethyst happen in and around the Hub region and its adjacent Valley areas.

Gather Amethyst Ore from nodes near spots like Bridge Approach, haul it back to the Core AIC area in the Hub for Refining and Fitting, and then carry finished products such as Amethyst Parts or Industrial Explosives to other quest zones including Originium Science Park and structures like Zipline Towers that need repairs or demolition items.​

How to unlock the path to producing Amethyst Parts

Before you can actually produce Amethyst Parts, you need access to ore nodes and basic AIC infrastructure.

• Push the main story until you reach the Hub region and unlock basic mining gameplay and mining drills for ores like Amethyst.
• Follow the early industrial and tutorial objectives around the Core AIC area to gain access to the Refining Unit, Fitting Units, and other processing buildings.
• Explore areas such as around Bridge Approach in the Hub, where Amethyst Ore spawns in mineable nodes that your drill can work on.​

As you advance the tutorial-like industry quests, the game gradually introduces more buildings and recipes, including the ones required to process Amethyst into higher-value products like Amethyst Components and Amethyst Parts.

How to get Amethyst Ore and Fiber first

Amethyst Parts sit in the middle of a processing chain, so you start by gathering ore and turning it into fiber.

Finding and mining Amethyst Ore

• Amethyst Ore appears as one of the early ores after Originium, commonly in Hub and early Valley areas.​

• A reliable farming route is around Bridge Approach near the Hub, where Industrial Explosives and Amethyst-related tutorials point you to Amethyst nodes.​

• Use your active mining rigs or drilling structures to harvest the ore from marked resource nodes, then send it back to your AIC storage.

Refining Amethyst Fiber from Amethyst Ore

Once you have ore, you convert it to a refined intermediate:

Place Amethyst Ore into the Refining Unit located near your Core AIC in the Hub to turn it into Amethyst Fiber.​

Queue enough Fiber production for upcoming needs because both Components and Parts consume fiber in different recipes, and quests often ask for multiple units.

Keep an eye on power and throughput of the Refining line so you do not bottleneck later explosives or gear production.

How to produce Amethyst Parts in the Fitting Unit

Amethyst Parts come from a separate industrial route than Amethyst Components, focusing on the Fitting Unit rather than the Gearing Unit.​​

Step 1: Locate your Fitting Unit

Head to the AIC section near the Core AIC in the Hub, where most early processing buildings cluster together.​

Look for the Fitting Unit structure; this is the facility for producing Amethyst Parts and other fitted outputs.​​

If you cannot see it, continue story and industrial objectives until building and research for the Fitting Unit unlock.

Step 2: Ensure you have Amethyst Fiber stock

• Check AIC storage for enough Amethyst Fiber produced earlier from Amethyst Ore.​

• If you are low, return to nearby Amethyst Ore nodes (for example around Bridge Approach) and mine more ore, then refine it again through the Refining Unit.

Step 3: Set up the Amethyst Parts recipe

Interact with the Fitting Unit and select the recipe that converts Amethyst Fiber into Amethyst Parts; this is the standard route.​

Confirm the number of Parts you want based on upcoming quests or crafting, then start the job so the unit continuously processes fiber into Parts.

Allow the process to complete and collect finished Amethyst Parts from the Fitting Unit’s output buffer or AIC inventory screen.​

Step 4: Keep a baseline production loop

• Leave a small continuous order for Amethyst Parts so you always have some in stock for explosives, repairs, or trade-related uses.

• Balance your production with other Amethyst products such as Amethyst Components, which you create separately via the Gearing Unit for gear crafting.

How to use Amethyst Parts in quests and industry

Amethyst Parts directly tie into quests and world interaction.​

Using Amethyst Parts for Industrial Explosives

Amethyst Parts are a key ingredient for Industry Explosives.

Step 1: Prepare Amethyst Parts and Aketine Powder

• Produce Amethyst Parts in the Fitting Unit using Amethyst Fiber as described above.​

• Collect Aketine Ore and process it in the Shredding Unit to obtain Aketine Powder, which pairs with Amethyst Parts in the final packaging step.​

Step 2: Package Industrial Explosives

• Move both Amethyst Parts and Aketine Powder into the Packaging/industrial explosives-related unit in your AIC.

• Use the recipe that combines these two items to manufacture Industrial Explosives, required for certain quests and environmental obstacles.

Step 3: Use explosives in the field

• Place the crafted Industrial Explosives into your backpack and equip the appropriate tool or mode to deploy them.​

• In quests like Dusty Old Files, use the explosives to clear Blight cores or obstacles that normal attacks cannot remove, opening new paths and chests.

Using Amethyst Parts for repairs and structures

Some objectives directly reference Amethyst Parts as repair materials, such as fixing a Zipline Tower in certain Endfield clips.

​

• When an objective asks you to repair an industrial structure (for example, a Zipline Tower), check the required items list; Amethyst Parts are often one of the listed resources.​

• Make sure you have enough Parts in your inventory, then interact with the structure and spend the requested quantity to restore it and unlock shortcuts or traversal options.

How to efficiently farm Amethyst-related materials

If you expect to use many Amethyst Parts, planning a loop around ore, fiber, components, and parts saves time.

Step 1: Set a regular mining route

• Identify multiple Amethyst Ore nodes in areas you visit frequently, especially in the Hub and early Valley zones like Valley Pass or near Bridge Approach.

• Rotate through them in a loop, giving time for nodes to respawn while you complete combat encounters or quests nearby.

Step 2: Balance ore processing lines

• Split Amethyst Ore between the Refining Unit (for Fiber) and other processing branches depending on whether you need more Parts or Components for gear.

• Keep Refining running whenever you are in the field so your stockpile of Fiber and Parts grows passively.

Step 3: Adjust output to your current goals

• If you focus on explosives-heavy quests and structure repairs, prioritize Amethyst Parts output from the Fitting Unit.​

• If your current bottleneck is gear, route more Fiber and other materials into the Gearing Unit to create Amethyst Components instead.

Amethyst Parts sit at the heart of Endfield’s early industry loop, bridging your mining operations with explosive tools and structural repairs across the map. By consistently mining Amethyst Ore, refining it into Fiber, and running a steady Fitting Unit line, you set yourself up to clear quests, open shortcuts, and fuel your broader exploration without stalling on resource checks.
