Trader route planner: fixed, roaming, and machine exchanges

What this trader guide is for

Abiotic Factor does not use one universal shop. Some traders remain in a known sector, some travel, and some exchanges happen through machines or special objects rather than an NPC trade screen. Treating all of them as ordinary vendors creates two common failures: carrying materials to the wrong place and expecting a roaming trader to keep the same stock indefinitely.

This page solves the route-planning problem. It identifies the ten trader entries in the current Trading reference, tells you which kind of stop each one is, and provides a safe way to verify a trade in the current game build. It does not duplicate every input and output from the in-game interface. Those lists can change, while the interface in front of the trader is the authoritative check for the save you are playing.

Diagram basis: the trader categories and interaction rules come from the current Trading reference. The diagram is a planning aid and is not a map or distance scale.

Current trader directory

The community Wiki's Trading reference lists ten trader entries. Use this table as a directory, then inspect the current trade screen for exact stock, cost, and unlock requirements.

The location column deliberately stays at sector or world level. A roaming NPC is not made reliable by publishing a single old coordinate, and a machine exchange is only useful if you reach the machine that performs the conversion you want.

How the four interaction types differ

Fixed NPC traders

Warren Bunning and The Blacksmith are examples of traders tied to known areas. These are good stops to combine with an existing route because you can plan the sector before loading your inventory. Fixed does not mean that every trade is available immediately. Warren's visible exchanges include progression unlocks, and The Blacksmith's role expands as Manufacturing West objectives advance.

Open the trade screen first, read the displayed cost, then move only the needed quantity into the exchange. Do not rely on a remembered recipe from an older patch when the current interface is available.

Roaming NPC traders

Grayson, Marion, and Carson are documented as traveling traders. Their route has an extra step: locate the NPC before carrying a full shipment across the facility. Traveling stock can be limited and replenishes over time, so a valid trade can still be unavailable during a particular visit.

When a roaming trader is missing or out of stock, that is not proof that the trade was removed. Record the location and stock state, continue the sector's main objective, and check again on a later pass. This avoids turning a stock wait into an unproductive search loop.

Quantum Exchangers

Quantum Exchangers are machines rather than NPC shops. The current Trading reference documents them in Cascade Laboratories, Flathill, and Reactors, with different conversions tied to particular machines. Items are placed into the open input chute and collected from the output chute at a one-to-one exchange ratio.

The one-to-one ratio does not mean every exchanger accepts every listed input. Confirm the screen at the machine, insert one test item, collect the output, and only then process the rest of the stack. If nothing happens, recover the item before assuming the machine is broken; you may be at the wrong exchanger.

Wishing Shelf

The Wishing Shelf in North Pole appears in the trader directory even though it is not a direct NPC trader. Its exchange list includes both multiplied returns and items that come back one-for-one. That makes it especially important to check the current documented behavior before offering a scarce progression item. Do not infer that a larger return for common scrap applies to every item.

Progression-aware route order

Use the player's current objective, not a universal ranking, to choose the next stop.

This ordering keeps a trader visit attached to progression or a resource route. It also provides a fallback objective if a roaming trader is unavailable.

Pre-trip exchange worksheet

Before leaving a base, write down five things:

1. Target trader or machine. Use the exact name, including the specific Quantum Exchanger location when relevant.
2. Desired output. Name the item you need and why it unblocks the next task.
3. Maximum input. Decide how many units you are willing to spend before the trip begins.
4. Unlock evidence. Note the story event, sector access, or visible trade state that confirms the exchange should be available.
5. Fallback objective. Choose a nearby loot, progression, or shortcut goal so a missing roaming trader does not waste the journey.

Carry one exchange batch rather than every copy of a scarce item. If the cost or output differs from the plan, stop and recheck the interface. The safest response to a changed trade is a smaller test, not a larger gamble.

Verified example: Blacksmithing Gloves

Blacksmithing Gloves demonstrate why a trader page needs both trade and loot paths. The current item reference documents a direct Blacksmith exchange: one Captain's Beret for one pair of Blacksmithing Gloves. It also documents glove locations in Manufacturing West, Cascade Laboratories, Security Sector, and Hydroplant.

The decision is therefore conditional:

• If a Captain's Beret is already available and you are willing to spend it, inspect The Blacksmith's current trade and use the direct exchange.
• If the beret is reserved for another purpose, check a documented glove location while completing work in that sector.
• In Cascade Laboratories, one documented location near the Pest Teleporter recipe requires a Jump Pad or Jetpack. Skip that elevated check when the mobility item is missing rather than inventing an unreachable route.
• Do not promise a time or a guaranteed loose-item respawn. Confirm whether the glove is present in the current save and move to the next objective if it is not.

This example is intentionally narrower than a full Blacksmith inventory. For Synchrotron parts and other Forge decisions, use the dedicated Blacksmith guide.

Failure recovery

The NPC is not where an old guide showed them

First check whether the trader is documented as roaming. If so, do not treat a single coordinate as permanent. Continue the nearby fallback objective and look again during a later route. If the trader is fixed, confirm that you are in the correct sector and that the relevant area is accessible in the current progression state.

The expected trade is missing

Some exchanges are progression-gated. Compare the current visible trade screen with the unlock state of the save. A missing entry is a reason to verify progression, not a reason to offer unrelated items to the trader.

The traveling trader has no stock

Limited traveling stock can replenish over time. Record the shortage and leave with the input item. Do not discard or spend a scarce material merely because the planned output is temporarily unavailable.

A Quantum Exchanger does nothing

Recover the test item, verify the machine location, and check the displayed conversion. Different exchangers perform different trades. Process the rest of the stack only after one item produces the expected output.

Completion checklist

A trader run is complete when all of the following are true:

• The correct trader, machine, or special exchange object was reached.
• The current interface showed the intended input and output.
• A limited or scarce input was tested in a controlled quantity.
• The output was collected before leaving the area.
• Any stock shortage or progression lock was recorded for the next visit.
• The remaining materials returned to storage rather than staying in a travel inventory.

Following this checklist matters more than memorizing a static catalog. The community Trading reference supplies the current directory; the in-game screen confirms the transaction available in the player's build and save.
