Raw crimson flux is a byproduct found on vegetation which has been affected by a high degree of radiation. It can be consumed to quench thirst and provide a boost to disease resistance.
However, raw flux decays rapidly into inert flux and must be stabilized at a chemistry station if it is to be used for crafting. One exception to this is that raw crimson flux is used directly in crafting orbital scan beacons.
Flux is acquired by harvesting the mutated flora in nuked zones. Raw crimson flux is specifically collected by harvesting the mutated variants of the following flora:
- Aster (Red hot bloom)
- Blight (Bright blight)
- Brain fungus (Enlightened fungus)
- Cranberries (Blast berry)
- Firecap (Blast cap)
- Mothman eggs (Ionized crackleberry)
- Wild gourd blossom (Boom bloom)
Raw crimson flux can be attained easily by launching a nuke in any biome containing one of these floras.
Mutated variants of the flora will have slight name and color changes to indicate the mutation.
