How to Get Inert Flux in Fallout 76

Inert Flux is created by allowing raw Flux (nuked flora) to spoil in your inventory. You can collect Raw Flux by harvesting plants in a recently nuked area called the Blast Zone. In addition, you can tell which variant of raw Flux is the best by looking at its color, which depicts its mutated status.

The table below shows the five types of raw Flux that you can obtain, what plants will turn into them when exposed to a nuke’s radiation, and the plant’s new name.

Raw Flux will spoil within 90 minutes and then turn into a consumable called Inert Flux, which provides +5 Disease Resistance and will fill your thirst meter by 25%. When this conversion happens, the game automatically removes the Raw Flux from your inventory and adds the appropriate Inert Flux.

What Perks Work with Inert Flux in Fallout 76?

You can use a couple of Perks to make Inert Flux even more effective. For instance, the Lead Belly perk reduces the radiation you receive when drinking liquids. This perk makes Inert Flux more effective than Purified Water since it adds +5 Disease Resistance. However, the Traveling Pharmacy and Thru-Hiker perks do not reduce Raw Flux’s or Intert Flux’s carry weight.

In addition, you can use the below perks:

  • Good with Salt: Makes food spoil 30% slower.
  • Green Thumb: Obtain double the amount of flora when harvesting.
  • Dromedary: Drinking liquids fill your thirst meter by an additional percentage.
  • Super Duper: When crafting anything, you’ll have a certain percentage chance to achieve double the results.

Can You Sell Inert Flux in Fallout 76?

As of Patch, which Bethesda released in 2019, the base value of Inert Flux was set to 0 Caps. In addition, you can no longer sell it to Vendors. However, Raw Flux is worth 10 Caps, and Stable Flux is worth 100 Caps, both of which can be sold to vendors and other players.

How to Create Stable Flux in Fallout 76

To create Stable Flux, you must use a CHemistry Station. This ability is unlocked by default, meaning you won’t need to search for a recipe.

Here are the materials you need to turn any Raw Flux into Stable Flux:

  • Glowing Mass x1.
  • Hardened Mass x1.
  • High-Radiation Fluids x1.
  • Any Raw Flux Variant x10.

Raw Flux will spoil within 90 minutes, meaning you must turn it into Stable Flux before this happens. Otherwise, you will end up with Inert Flux.
