|||Aura contains information about the ThaumCraft_2 mod.|
Aura is Vis Energy that is released by a mob when they are killed. This energy stays dormant until absorbed by another creature or object. ==Use== Aura can be absorbed by particular magical creations and be turned into usable Vis. However, there is a limited amoun of aura in an area and using too much of it can have consequences. The amount of living things in an area depends on the amount of aura.
To suck taint out of an area, use a condensor with the researched upgrade Concentrated Evil. To increase the aura, throw concentrated Vis potions and/or place Totems of Dawn. These will not only raise the levels of aura, but also prevent the growth and spread of Taint in that chunk
