Thaumcraft is a Game Mod for Minecraft revolving around the concept of converting materials into a raw energy called Vis. With this energy, Minecraftian wizards can infuse items, dig up the earth, and even duplicate precious gems.We are now on Thaumcraft 4.
Awesome, but Impractical: The Crystal Core, Made from four mixed crystal clusters and a nether star. when the proper arcane structure is made this object pulls the nearest Aura Node to it, however the range at which it can draw aura nodes is not very far and if you wish to move a node over a large distance you need multiple cores seeing as how this requires a nether star you're going to be spending quite a bit of time in the nether for wither skulls.
However, breaking the "used" Crystal Core yields the original number of shards (a few changed to dull) and the nether star back, so it's only necessary to replace the clusters and infuse them again.
Cast from Hit Points: If you're desperate for Magic Tallow, letting yourself get burned in a crucible will create some...
Or if you are using Thaumcraft in a modpack( like Feed the Beasts many modpacks) you could equip a high end armor from another mod and stand in your crucible for a few minutes, a painless form of tallow making, which may not even damage you or your armor(depending on what you had equipped).
Giant Mook: In the third iteration of Thaumcraft,pumping too much Flux(a new mechanic to replace taint) into the Aura can result in "A nearby Node spews forth something Foul." which means a Giant version of an angry zombie has spawned. Hitting it makes it grow even larger and can kill you in three hits with iron armor.
Giant Angry Zombies spawn when there is too much mortuus aspect in the aura as flux, seeing as how zombie flesh is an easy source to make Magic Tallow from, when you dont have Basic Flux research done and the arcane alembics made, these tend to be common if you like making Tallow from Zombie Flesh.
Infinity+1 Sword: The Wand of the Thaumaturge in Thaumcraft 3, it is bar none the game's best wand for use in Thaumaturgy holding 1000 Vis. you do however need to research a number of things before the ability to research this wand comes up, once you do unlock it, you find out you need a Nether Star to make the wand, yes that's right, you need to kill TheWither to make the wand. have fun.
Kill It with Fire: The Wand Of Fire, made from a wand of the apprentice and three fire shards.
Kill It with Ice: The Wand of Frost, Made from a wand of the apprenticeand three water shards.
Portable Hole: There is an item called the portable hole, which opens up a temporary 2x2 square tunnel, which the player can pass through.
Shock and Awe: The Wand of Lightning, Made from a Wand of the Apprentice and three Air Shards, fortunately using it on a creeper does not supercharge it.
The Corruption: If an area's atmosphere becomes saturated with Taint, surface-level blocks will gradually change into Taint Blocks. In addition to making them impossible to extract usable resources from, most mobs that spawn on them will be Always Chaotic EvilLightning Bruiser versions of themselves.
This is done away with in Thaumcraft 3, Taint being replaced with Flux. It still has consequences for overdoing things with thaumaturgy but no longer to the extent of the world destroying levels of taint that were possible in Thaumcraft 2.
Taint is back in Thaumcraft 4, in the shape of small biomes automatically created on world gen. Their spreading can however be turned off in the mod's config file.
Too Dumb to Live: People who actually summon the Super Charged Thaumic Slimes without backing up their world.
