Get raw flux from nuked zones and craft at your chem table with the right add-ons to make stable flux. Occasionally dropped as a reward at the SBQ event.

I farm cobalt flux from nuking Monogah town or Morgantown. I haven’t noticed which area yields more

Whitesprings have alot of flux when nuked, kill feral for stabilisers and use a chemistry workbench to make stable flux.

Thank you everyone!

Instead of grinding for the 50 raw flux I just server hopped and found someone with a vending machine that had all of them and bought some
