Water Crystal

ModThaumcraft 6
TypeTransparent block

The Water Crystal is a glowing ore added by Thaumcraft 6. It is found in clusters of 1-64. When mined, it will drop 1-4 Aqua Vis Crystals (the number of crystals it will drop is countable by looking at the block). Silk Touch is ineffective against the Water Crystal.

Water Crystals will grow from the Aura in the air. However, they cannot be farmed without the Crystal Farmer Research.

Crystal Farmer Research

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

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.
