What to know
-
You get Arc Resin as a rare drop from ARC enemies, with better odds on tougher machines.
-
You can also find it by searching ARC wrecks like Baron/Deforester Husks, ARC Couriers, and ARC Probes.
-
The Electromagnetic Storm map condition is one of the best times to farm because it spawns lots of crashed Probes to search.
-
Arc Resin is needed for Trophy Display Phase 4/5 (Dominant Dangers), requiring 10 total.
Arc Resin or ‘ARC Synthetic Resin’ in Arc Raiders is not a fixed spawn pickup, so the best map setup is the one that maximizes ARC fights and searchable ARC wrecks. Basically, you are not looking for one magic spot on one map here. You are looking for the most repeatable loop.

So hunt ARC machines, then sweep nearby wrecks before extracting.
| Quick overview | What to do |
|---|---|
| Best map situation | Queue into runs with Electromagnetic Storm active to increase Probe wrecks to search. |
| Best source type | Tough ARC machines (higher chances) plus searchable ARC wrecks. |
| What to prioritize | Wasps/Hornets if you need quick kills, Leapers/Shredders/Queens for better odds when you can handle the fight. |
| How it behaves | No fixed location; drops are RNG from ARC kills and searches. |
| Project use | Trophy Display Phase 4 needs 10 Arc Resin. |
Maps and map conditions that matter
Electromagnetic Storm is the closest thing to a best map for Arc Synthetic Resin farming because it pushes more crashed ARC Probes onto the map, letting you stack search attempts while also hunting regular ARC enemies along the way.
How to farm Arc Resin efficiently
Step 1
Pick runs with Electromagnetic Storm, then plan your route to hit open ground where crashed Probes are likely to be visible and quick to search before you commit to longer fights.
Step 2
Take ARC fights that you can finish cleanly, because Arc Resin is obtained by looting ARC enemies, and tougher machines have higher chances than basic ones.

Step 3
After each fight, do a tight sweep for ARC wrecks nearby, prioritizing ARC Probes and bigger husks, since Arc Resin can also come from searching old ARC wrecks like Baron/Deforester Husks, ARC Couriers, and ARC Probes.
Step 4
Extract as soon as you have enough for your current goal, because the limiting factor is usually surviving long enough to bank the drops rather than finding one specific spot.

Rewards and uses
| What you get or do | Why it matters |
|---|---|
| Submit Arc Synthetic Resin to Trophy Display | Phase 4/5 (Dominant Dangers) needs 10 Arc Resin. |
| Recycle Arc Resin | It can be recycled into Plastic Parts (shown as Plastic Parts x14 on some databases). |
| Sell Arc Resin | It is listed as sellable for 1,000. |
Basically, treat Electromagnetic Storm as your go-to map condition, then alternate between ARC kills and quick searches of Probes/Couriers/Husks until you have the 10 you need.
