Origocrust Refining Units are one of those materials in Arknights: Endfield that feel unimportant at first, then suddenly become unavoidable. You will not touch them in the early game, but once advanced weapons, buildings, and late upgrades unlock, progress can slow down completely if you are not ready.

Unlike materials gathered from exploration or combat, Origocrust Refining Units are fully industrial products. They come from refining Originium ore inside your base, which means production depends heavily on facilities, power supply, and logistics planning. This guide explains what Origocrust Refining Units are, when they unlock, and how to produce them efficiently without wasting resources.
What Are Origocrust Refining Units in Arknights: Endfield
Origocrust Refining Units are advanced materials created by processing Originium ore through specialized refining facilities. They are not dropped by enemies or found in the open world.
- Resource type: Processed Originium material
- Source: Refining facilities
- Unlock phase: Mid-game
- Main use: High-tier crafting and upgrades
- Production type: Fully automated base processing
Because they are refinement-based, supply often lags behind demand if production is not prepared early.
What Origocrust Refining Units Are Used For
You will start seeing Origocrust Refining Units appear in crafting and upgrade recipes once you reach advanced progression stages. They are commonly required for:
- Crafting high-rarity weapons
- Upgrading advanced base facilities
- Producing late-stage industrial components
- Unlocking certain technology and research paths
Demand for these units usually spikes all at once, which is why preparation matters.
When Origocrust Refining Units Unlock
Origocrust Refining Units cannot be produced from the start of the game. Access is tied directly to progression. You must:
- Advance the main story
- Reach the required Authority Level
- Unlock higher-tier base facilities
For most players, this happens naturally during the mid-game, shortly after basic automation and base systems are fully established.
How to Unlock the Refining Chain
Before Origocrust Refining Units can be produced, the refining system itself must be unlocked. This happens during Andre’s questline in the Rally and Unite phase. Key unlock conditions:
- Story progression that grants industrial technology
- Authority Level milestones that gate new buildings
- Base expansion to allow advanced structures
Once these conditions are met, refining buildings become available in the construction menu.
How Origocrust Refining Units Are Produced
Origocrust Refining Units are generated automatically through refining facilities. There is no manual crafting involved. Production flow:
- Collect raw Originium ore
- Transport it to a refining facility
- Consume power over time
- Output Origocrust Refining Units
Because this process is automated, stable logistics and power management are just as important as raw materials.
Setting Up the Refining Facility
Step 1: Unlock the Refinery Building
You need access to the Origocrust Refinery or an equivalent advanced refinery tier. This building only appears after completing required tech unlocks.
Step 2: Place the Refinery Strategically
Refineries consume large amounts of power and require constant input. Place them close to:
- Power generators
- Storage facilities
- Conveyor belts or transport nodes
Good placement reduces downtime and inefficiency.
Step 3: Connect a Stable Power Supply
Refining will not function without sufficient power. Any power dip immediately halts production, so your grid must support continuous operation.
Step 4: Feed Raw Originium Ore
Refineries automatically pull materials from connected storage. Make sure raw Originium ore is stockpiled before activating production.
How to get Originium Ore for Refining
Origocrust production speed depends entirely on your raw ore supply.
Common Originium ore sources:
- Open-world mining nodes
- Industrial extraction zones
- Automated mining facilities
Manual collection works early on, but automation becomes mandatory once refining begins.
Automating Origocrust Production
To maintain consistent output, automation is essential.
Recommended setup:
- Locate dense Originium ore areas
- Build extraction facilities near mining zones
- Route extracted ore into storage buffers
- Connect storage directly to refineries
This setup ensures refining continues without constant player input.
How Long Origocrust Refining Takes
Production speed depends on several factors:
- Refinery tier
- Power stability
- Consistent material input
In general:
- Early setups are slow but reliable
- Upgraded refineries greatly improve output
- Slow pacing early is intentional
Refining is meant to feel gradual at first.
Recommended Originium Ore Stockpile
You do not need massive reserves immediately, but running out causes major delays. Suggested stockpile targets:
- Early mid-game: 50–100 units
- Late mid-game: 150–500 units
- Late game: Maintain a surplus
Keeping a buffer prevents upgrade bottlenecks.
Origocrust Refining Units are a major progression check in Arknights: Endfield. You cannot rush them, but you can prepare for them properly. Unlock refining as soon as possible, automate Originium ore extraction, and stabilize your power grid early. Treat refining as a long-term investment. Set it up once, scale it slowly, and let automation handle production while you focus on exploration and combat.
