Inert flux is a consumable item in Fallout 76.


Inert flux is a consumable that is the result of allowing collected nuked flora (raw flux) to decay. It gives the consumer a +5 disease resistance and quenches thirst by 25%. To preserve the raw flux and prevent it from turning into inert flux, it must be crafted into stable flux, which will also allow it to be used to craft end-game recipes.


The following types of raw flux will decay into inert flux after a certain amount of time has elapsed:


It is added to the player character's inventory and replaces raw flux after a certain amount of time.


  • Prior to Fallout 76 patch, the weight was 1 and the value was 10.
  • Inert flux is more efficient than purified water with the Lead Belly perk, providing the same 25% hydration with an added disease +5 resistance while being 43% lighter.
