Blue Crystal
A Blue Crystal is the stone set into every zombie collar: bronze, golden and steel collars each take one at the Jewelry Table. No recipe makes it. After you have met the Goddess of Nature in the Swamp, her tears give you 4 every Envy day for free; otherwise Gunter at the astrologer’s tower sells 10 from his second tier and buys them back.
Gunter reaches his second tier during his port quests and his third with Congregation Trouble. In alchemy the crystal carries 1 green and 2 blue runes.

Notes
- One crystal per zombie. Collars are used up when a zombie is raised, so every new zombie costs a crystal.
- Studying it costs 15 Science and gives 10 green and 20 blue.
