Flux Crystal

ModThaumcraft 6
TypeTransparent block

The Flux Crystal is a glowing ore added by Thaumcraft 6. It is found in clusters of 1-64. When mined, it will drop 1-4 Vitium Vis Crystals (the number of crystals it drops is determined by looking at the block). It is unaffected by Silk Touch.

Flux Crystals will grow with enough Flux. However, they cannot be farmed without the Crystal Farmer Research.

Crystal Farmer Research

"Crystal Farmer" is a Research added by Thaumcraft 6. With it, Vitium Vis Crystals can be used to make Flux Crystals in an Infusion Altar, as seen below.




Instability: Negligible

They can be also acquired by placing an overflowing Crucible near (but not above) the six primal aspect crystals.

Vis Crystals

On occasion there is so much primal energy in an aura that it will settle into rock from which vis infused crystals will grow. As long as they are fed vis they will continue to grow and even spread.
Once the aura dips low enough the energy once again dissipates out of the crystals, replenishing the aura and causing the crystals to crumble. In effect, they are natural, or in this case, supernatural vis batteries. They will never crumble away completely and at least a small remnant of the crystal will remain.
These crystals can be harvested for elemental shards that have many uses in Thaumaturgy.

You have yet to discover a method to extract individual crystals without destroying the entire cluster. It is a matter of all or none.
Vis crystals growing in tainted areas may become tainted as well.
I have found a way to way to reinvigorate vis crystals in such a way that I can replant them

I am hoping by these means I can grow my own steady supply of primal vis crystals.
