- This page is about Flux Flu from Thaumcraft 4. For other uses, see Flux Flu.
Flux Flu is a status effect added by Thaumcraft 4. Players afflicted with Flux Flu receive a 30% increase penalty in vis cost. This can be acquired through touching Flux Goo or Flux Gas.
If Warp is the mental manifestation of magic gone wrong, then Flux is its physical manifestation.
Flux can manifest in three ways: a liquid, a gas and a physical malady. The first two manifestations are considered annoyances by most thaumaturges and is often the result of wasteful use of magic. It is not particularly hard to clean up, but coming into contact with it often causes the third manifestation: Flux Flu
Flux Flu is not particularly dangerous, but while a thaumaturge is suffering from it he finds it difficult to focus vis which often leads to increased vis usage to get something done.
