Flux is one of the “endgame materials” in Fallout 76. You need Flux in different colors for the best mods and equipment. We will show you how to obtain and process it.
What is Flux? Flux is the residue of radioactive plants in Fallout 76. Flux is highly unstable and decays in your inventory after a short time. To process it, you first need to stabilize it.
What is Flux used for? With Flux, you can create “premium closures” for various weapons, the best mods for your underarmor, and some items for your C.A.M.P..
How to craft and process Flux
How to collect raw Flux: You get Flux from all plants in the impact area of a nuclear bomb. All plants within the corresponding red radius are transformed and even receive different names.
You can collect the plants just like their “normal” counterparts. The Perception perk “Green Thumb” even grants you double the yield. When you harvest a plant, you receive the raw Flux directly into your pockets instead of a plant. There are five types of Flux:
- cobalt Flux
- fluorescent Flux
- yellowcake Flux
- purplish Flux
- violet Flux
In the Whitespring Bunker, you will find notes on Flux and which plants yield the respective colors.
Stabilizing Flux – here’s how: You cannot use raw Flux to craft mods. You must first stabilize it. You will learn the recipes for this as soon as you collect Flux for the first time. You can then stabilize Flux at a workbench under “radioactive flora”.
To craft stabilized Flux, you need:
All the required items can also be found in Fallout areas of nuclear bombs. Every enemy in these zones has a chance to drop the respective items. Unlike raw Flux, the items do not have durability and do not decay.
Hardened mass can also be broken down into Ultracite and was automatically scrapped until the patch on January 10. This should no longer happen.
Stabilized Flux no longer decays and can be stored and processed further. With the Luck perk “Super Duper”, you have a chance to produce double the amount of stable Flux every time.
Finding stable Flux: You can also find stable Flux directly. This is somewhat more difficult. When a nuclear bomb is dropped on the “Rift Location Prime”, a level 95 (Elite) Scorchbeast Queen will appear.
The associated event “Burned Earth” is then open to all players on the server. You have the chance to obtain stable Flux directly for both completing the event and killing the queen.
What can I craft with Flux?
Recipes for Flux: To ultimately process Flux, you first need the corresponding recipes. You can also obtain these from the Scorchbeast Queen.
The recipes include:
- premium closures that deal more damage to the weapon and bonus damage against Scorchbeasts and Burned.
- Ultracite ammunition for weapons with premium closures (learned with the closure).
- mods for underarmors like “shielded”, which increase resistances and S.P.E.C.I.A.L. values.
- C.A.M.P. items like decontamination arches that remove all RAD.
Raw Flux is also necessary for some recipes such as orbital strike grenades or orbital scanners.
Thus, Flux is important for players who want to become stronger even in the endgame of Fallout 76.
Tip: If raw Flux decays in your inventory, it turns into inactive Flux. You can still use this. On the one hand, all vendors pay a good price for inactive and raw Flux.
On the other hand, you can drink inactive Flux for a large amount of liquid. The radiation absorbed is less than that of boiled water, but the increase in liquid is as high as that of treated water.
