What else can I say? It's a brain in a jar. It does occasionally whisper something useful - maybe you should use it instead of bookcases for enchanting or research...
It functions identically to a Bookcase for Enchantment Tables, Thaumic Enchanters, Quaesitums and Occultic Enchanters. Additionally, it improves the speed of Occultic Enchanters and reduces the failure rate and loss rate of a Quaesitum.
On some older versions of Thaumcraft, this recipe may work:
- The Dark Infuser discovery is a prerequisite to getting the Brain-in-a-Jar theory.
- This discovery can only be made researching Zombie Brains. It is a prerequisite for the Occultic Enchanter.
- It is classified as Forbidden Knowledge.
- When the player approaches, the brain will turn towards them.
