Industrial Explosives are a craftable utility item in Arknights: Endfield used during exploration, combat encounters, and certain missions. A small automated factory can produce them continuously inside the AIC base by converting plant and mineral resources into bomb components and packaging them into finished explosives.
Quick answer: Industrial Explosives are produced in a Packaging Unit using 5 Amethyst Parts and 1 Aketine Powder, with a total crafting time of about 10 seconds per bomb.
Industrial Explosives crafting recipe
The explosive itself is the final step in a short production chain. Raw materials are processed through several machines before the Packaging Unit assembles the finished item.
| Stage | Input Material | Facility | Output |
|---|---|---|---|
| 1 | Aketine (plant) | Shredding Unit | Aketine Powder |
| 2 | Amethyst Ore | Refining Unit | Amethyst Fiber |
| 3 | Amethyst Fiber | Fitting Unit | Amethyst Parts |
| 4 | 5 Amethyst Parts + 1 Aketine Powder | Packaging Unit | Industrial Explosives |
The Packaging Unit consumes the processed components and outputs a completed explosive roughly every ten seconds when supplied continuously.
Facilities required for the explosives blueprint
A minimal automated layout requires only a handful of structures. Once connected with conveyor belts and powered, the system can run indefinitely as long as raw resources are supplied.
| Facility | Purpose | Notes |
|---|---|---|
| Packaging Unit | Combines materials into Industrial Explosives | Final production step |
| Fitting Unit | Converts Amethyst Fiber into Amethyst Parts | Feeds the Packaging Unit |
| Refining Unit | Processes Amethyst Ore | Produces Amethyst Fiber |
| Shredding Unit | Grinds Aketine plants into powder | Provides the explosive reagent |
| Electric Pylon | Powers the production chain | Required for all machines |
Belts usually route Amethyst products through the refining and fitting steps before merging with the Aketine Powder line at the Packaging Unit.
Industrial Explosives blueprint code
A commonly shared compact layout for early AIC bases uses the following blueprint code:
EFO01893u6Ou8A122UI73Importing a blueprint places the machines and conveyors automatically, creating a small assembly line that converts Aketine and Amethyst resources into explosives. The layout prioritizes simplicity and minimal space usage, which makes it easy to place near other early‑game production lines.
How the explosives production line works
The blueprint organizes the processing chain in a straight logistics flow:
- Aketine enters a Shredding Unit to become Aketine Powder.
- Amethyst Ore is refined and then shaped into Amethyst Parts.
- Both materials converge at the Packaging Unit.
- The Packaging Unit outputs Industrial Explosives to a belt, stash, or depot.
The Amethyst side of the chain is usually the slowest segment, which can create a small bottleneck if the ore supply is limited. Increasing ore input or duplicating refining steps raises output when larger bomb stockpiles are needed.
What Industrial Explosives are used for
Industrial Explosives serve several practical purposes across the world map.
| Use case | Description |
|---|---|
| Environmental destruction | Break destructible walls and obstacles blocking exploration paths. |
| Blight Core removal | Destroy hazardous objects tied to environmental hazards. |
| Combat damage | Thrown explosives can damage enemies at the start of fights. |
| Quest objectives | Some missions require explosives when no environmental barrels are available. |
Exploration often places destructible barriers in locations without nearby explosive barrels, making portable bombs necessary to progress or access hidden routes.
How to confirm the blueprint is working
The factory is functioning correctly when the Packaging Unit periodically outputs Industrial Explosives onto the connected belt or into a storage container. Continuous output indicates that both Amethyst Parts and Aketine Powder are arriving without interruption.
If production stops, the cause is usually one of two conditions: the Amethyst chain has run out of ore, or the Shredding Unit is not receiving Aketine plants. Restoring either input immediately resumes explosive production.
A small automated line like this can generate hundreds of bombs quickly, allowing players to stockpile explosives and disable the factory once a large reserve is stored.
