As this is a WIP, please report bugs! I am open to suggestions.
Thaumic Exploration is open-source, and found on github.
Content
Thaumic Exploration currently contains six new blocks (two are remakes of Thaumcraft 2 blocks), one new wand rod, three new enchantments, four new usable items, and a few new transmutation recipes. Exact content can be found in the below spoiler
Chest and Jar binding seals: The original inspiration of this addon, they are some of my favorite items from this addon. Use these seals on two or more chests, or two or more warded jars to link their inventories. No more messy infusion rooms! (See below media)
Brain Curing: You have finally found a way to cure zombie brains. They are used in the Think Tank and TC4's advanced golems.
Think Tank: A block that generates research fragments when supplied with books.
Everfull Urn: Infinite water source. Use buckets, or cap it off with Buildcraft or Thermal Expansion pipes. Also fills nearby crucibles and puts out burning players.
Crucible of Souls: Slowly kills mobs for their precious essentia.
Amber Wand Core: A low-capacity, fast refilling wand core, perfect for smaller recipes. There is also a corresponding staff core.
Thaumic Replicator: A block that replicates building blocks in exchange for essentia.
Boots of the Meteor: Boots that allow you to jump high and deal AoE slam attacks.
Boots of the Comet: Boots that allow you to run really, really fast. They also temporarily freeze water.
Wispy Dreamcatcher: Anti-taint device that lowers taint damage.
Talisman of Nourishment: Stores food and automatically feeds you. Never eat again!
Sojourner's Wand Caps: Vis-seeking wand caps that automatically drain nearby nodes.
Mechanist's Wand Caps: Wand caps that dramatically increase node draining speed.

Bah do whatever I've received way too many notifications 
I would love to see this mod in 1.12.2...
anyone have an idea as to why my staves from this mod won't equip foci? wands do it just fine, but staves won't even bring up the dial
is this mod dead ?
In reply to kuroyure:
If anyone else runs into the issue with the everburn urn and piping the lava out causing your game to crash when you go near it, there are updated versions on github somewhere on a fork
In reply to Walkman:
Good job, you did so well Azanor literally put some of the stuff in thaumcraft 6 including a thing similar to the binding seals, the Everful Urn (by the same name), the think tank, and a thing like the crucible of souls.
In reply to roidfludd:
I continue to crash every time I use this- but this mod is so good! Any solutions?
1.10.2 thaumcraft put update please
This mod is in conflict with rei's minimap mod
any plans to update to 1.11.2?
Could you at least post the latest version for download?
I just checked the TC4 wiki recently and I noticed this image labeled "Upcoming Necromantic Infusion" in the Thaumic Exploration description. Is this going to be implemented into Thaumic Exploration 1.7.10 and/or somewhere else at some point?
I do understand that you are most likely very busy with Thaumic Tinkerer 1.8.
Since I am not the most avid follower of minecraft forums/jenkins/wherever else, I probably missed a memo somewhere, so I do apologize in advance.
Thanks for any info. :)
Are you continuing Flaxbeard's work? If so, that makes me really happy.
