Raw cobalt flux is a consumable in Fallout 76.


Raw cobalt 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 cobalt flux:

Name Produces Normal Mutated
Bloodleaf Quantum leaf FO76 Bloodleaf new nif 2.png FO76 Bloodleaf new nif 1.png
Glowing resin Gloam sap
Firecracker berry Bomb Berry
Silt bean Neutron pod FO76 Silt boi.png FO76 Blue silt boi 2.png
Starlight creeper Kiloton creeper FO76 Starlight berries.png
Wild corn Aftershock stalk
Wild mutfruit Wild fission fruit


Despite acting as a food or chem when consumed, neither Thru-hiker nor Traveling Pharmacy will reduce the carry weight of raw flux.
