ARC Coolant in ARC Raiders drops from ARC enemies, especially the easier roll-style bots like Pops and Fireballs, and it’s also listed as coming from larger ARC types such as Sentinel, Surveyor, Queen, and others. It’s most efficiently farmed in high-loot red zones where ARC density is higher.

Best places to look

  • High-value red loot zones on any map, since they spawn more ARC enemies.
  • Dam Battlegrounds areas like Hydroponic Dome Complex and Research and Administration.
  • Stella Montis spots like Assembly, Lobby, and Business Center, where Pops and Fireballs seem common.
  • Baron Husks during electromagnetic storm map conditions.

Easiest enemies to farm

The most commonly recommended targets are Pops and Fireballs, because they’re easier to kill and can drop ARC Coolant more often than heavier machines.

If you can handle tougher fights, larger ARC enemies can also drop it.

Fast farming tip

Run into a red zone, clear every ARC you see, then loot the bodies immediately; the item is not crafted and is meant to be scavenged from destroyed ARC machines.

A simple farming loop is: enter red zone, hunt Pops/Fireballs, loot all downed ARCs, and extract once you’ve got enough.
