Raw crimson flux is a consumable item in Fallout 76.


Raw crimson flux can be attained by harvesting flora in a recently nuked zone. Mutated variants of the flora will have name and color changes to indicate the mutation.[1] It can be consumed to quench thirst and provide a boost to Disease Resistance.

Raw flux decays rapidly into inert flux and must be stabilized at a chemistry station to be used for crafting.


The following variants of flora produce raw crimson flux:

  • Generally the color of the flora indicates the type of flux acquired. Exceptions include the blastcap which is purple and blue.
  • The fever blossom would mutate into volatile fever blossom, but it is impossible to acquire as the only plant occurring outdoors is likewise in a zone that cannot be nuked.
