Pure crimson flux (Fallout 76)

Pure crimson flux is a component in Fallout 76.

Characteristics
While processing it renders it impossible to consume, it does turn it into a vital crafting component, used in a variety of high level crafting recipes, including: Prime receivers (used against the scorched), fusion cores, overdrive servos and targeting HUDs for power armor, as well as the Eagle Eyes, Egg Head, Marsupial, and Scaly Skin serums.

Locations

 * Raw flux can be harvested from plants in nuked zones (see above) and processed into stable (or pure) flux.
