Flux

Flux is a variant of crafting components or consumables in Fallout 76.

Characteristics
The crafting variants are ultra rare crafting materials whose components are found only around nuclear strikes. The crafting variants are key components for making Fusion cores, power armor mods, and under-armor mods. The Inert flux variant is a consumable that is created whenever any raw flux variation's material shelf life has ended.
