This article is about the concept from Thaumcraft 4. You may be looking for Vis from Thaumcraft 3.

Vis is a type of energy added by the Thaumcraft 4 mod. Vis can be gathered from Aura Nodes or by killing mobs and is stored in wands. The player can also energize Aura Nodes, allowing it to emit Vis directly.

Vis has a wide usage in Thaumcraft 4. It is used for the recipes in Arcane Worktable where a wand with Vis on it has to be placed as a Vis source. It is also consumed by some machines, f.e. Focal Manipulator, Advanced Alchemical Furnace or Infernal Furnace. These machines consume Vis in a form of Centi-Vis (CV) which is produced by energized Aura Nodes and can be transported by Vis Relays.

Vis comes in the form of 6 primal aspects:
. Each wand can hold the same amount of Vis of each type. Each machine only needs certain types of Vis.

Vis can be gathered in wands by holding right-click on an Aura Nodes, which results in draining them. This process can be automated by placing wand on a Wand Recharge Pedestal. Wands can also be recharged by collecting Vis dropped by every killed mob. Each mob doesn't drop many vis points, but an effective mob grinder can be better than harnessing vis from many Aura Nodes.

Vis is also used by some construction recipes in Thaumcraft 4; for example, constructing the Infernal Furnace has to be completed by right-clicking the structure with the wand with enough Vis. This amount will be taken from the wand.
