Thaumcraft 4

Thaumcraft 4 is a continuation of the Thaumcraft 3 mod, both created by Azanor. Thaumcraft is based off of the form of magic known as Thaumaturgy. A person who performs Thaumaturgy is called a Thaumaturge. This person is also defined as a person who works wonders and performs miracles using the magical essences inside physical objects.

Thaumonomicon
To start your magic adventure into Thaumcraft 4 you will need your Thaumonomicon. To craft the Thaumonomicon, you must create your first Wand and right click with it on a bookshelf that's placed in the world.

The Thaumonomicon is a reference book of all things thaumaturgical. It lists all the discoveries you have made so far and gives you a general impression of how much is left to learn.

Whenever you successfully research something and use the scroll, it will automatically be added to the Thaumonomicon. You can then browse through the discoveries and click on them to show more detailed information and any crafting recipes associated with those discoveries.

Plants & Trees
Greatwood trees are the large and majestic trees that can be found dotted all over the countryside.

Their Wood is able to absorb impressive amounts of magic making it a popular component in the crafting of magical devices.

Silverwood trees are the rare and magical trees and a wondrous sight. Their Leaves shimmer with magical energy and their pale, soft Wood is valued for its purifying properties.

The trees magical nature is such that aura nodes often form within their hearts - this feature alone makes Silverwood Sapling a prize beyond all measures.

Shimmerleaf is the strange, glowing flowers that only grow in the shadow of Silverwood trees. Instead of nectar, these flowers produce Quicksilver by breaking them with your hand.

Cinderpearl is the hottest flower, therefor it can only be found in the hottest climates, these plants burn with elemental fire. They can be broken up to produce a fine powder akin to Blaze powder.

Mana Pods are the strange, pod-like plants only found growing on trees in the magical forests. The growth is very slow and when harvested usually yield one or two beans. These Mana Beans contain concentrated amounts of essentia. They can also be consumed, though the results are often a bit unpredictable. They can be replanted, but cultivation is difficult and time-consuming.

Ores
Infused stone is stone blocks with so much primal energy in an aura that it will settle into solid stone to form infused ore. The magic forms crystals within the rock that can be harvested.

These crystals have various elemental properties and have many uses in Thaumaturgy. There are six types of shards that are harvested from these infused stones (Air, Fire, Water, Earth, Order, and Entropy) with each representing one of the primal aspects.

They can be combined together to form crystal clusters of each primal aspect (Aer, Ignis, Aqua, Terra, Ordo and Perditio. Crystal clusters are used to make magic more stable and are used in infusion crafting to enhance safety. Breaking a crystal cluster causes it to shatter into its component crystals.

Cinnabar is the reddish ore found deep underground, and when smelted it produces Quicksilver.

Amber Ore is found near the surface and when mined it drops chunks of Amber.

The Pech [W.I.P]
These strange humanoids can be found wherever the veil between worlds is at its thinnest. They seem drawn to the magical energies that abound in such places.
