Bioluminescent fluid is a consumable in Fallout 76.


A beaker of green luminous fluid obtained from the corpses of fireflies and radtoads. Its biological properties are unknown, but if a sufficient quantity is placed into a large light, it can attract the Mothman. If left for too long, it becomes spoiled bio fluid.


From the remains of fireflies and radtoads. It is used in the Path to Enlightenment event to put into the Landview Lighthouse lamp in order to attract the Mothman.
