Flux (Thaumcraft 3)

Using magic is never without risks and nothing proves this a much as Flux. If the magical Aura can be described as a still pool, Flux is the ripples and eddies caused by a rock dropped into it. It is not a corruption of the magic, but a disturbance - order turning to chaos and the natural laws being turned on their head.

Luckily auras almost always strive for order and balance, and this usually means that Flux is purged from them in some way. the exact form this takes can vary vastly and depends on the type of flux present in the Aura. The simplest and most common is the spontaneous generation of the magical creatures known as Wisps. Lightning strikes, storms or mysterious illnesses or boons can all be held as examples of Flux being purged from an Aura.

Only the brave or foolish practices magic without keeping an eye on how much Flux they are letting loose into the environment.
