Mods/Thaumcraft/Items

Ordinary Items
A few ordinary items have non-standard forms. Most notably, iron ingots can be crafted to and from iron nuggets, just like gold with gold nuggets. As well, Rotten Meat can be crafted 9:1 into a ../Block Of Flesh/. This can be disassembled by placing and mining it.

Ores and Minerals
There are several new ores, and one wrinkle for some existing ones:
 * Amber Bearing Stone -- Unsurprisingly, yields ../Amber/, one piece per ore block. (The Fortune enchantment does not work on Amber.)  Amber is used in certain advanced recipes.  Amber can be crafted to and from an Amber Block, 4 pieces to the block.
 * Cinnabar -- This mines as ore blocks, which can be smelted into ../Quicksilver/. Quicksilver is used in advanced crafting, notably for essentia tubes and magic mirrors.
 * Aspect Infused Stone (six kinds) -- These appear very different from other ores, with glowing traceries that are visible in the distance and darkness. There are six types for the six Primal ../Aspect/s, each with its characteristic color. When mined, they yield Aspect ../Shard/s, used for magical crafting and enchanting.  (Fortune does improve the yield for these.)   Six shards can be combined into a "crystal cluster", which helps with research and infusion enchanting.  The shards in a cluster must either be all the same type, or one of each type (for a "mixed cluster").
 * Iron, Gold and Cinnabar ores can be mined (or purchased from ../Pech/) as "native clusters". These smelt faster and produce twice as much material as blocks of ore.  The ../Pickaxe of the Core/ can produce native clusters when mining the corresponding ores.
 * A number of new materials can be crafted, but one warrants mention here: ../Thaumium/ can be made with a ../Crucible/, and can be crafted into armor and tools (including swords) which nearly match diamond.  Thaumium tools can also be enchanted by ../Infusion/ into Thaumcraft's special tools, with unique capabilities.  Thaumium armor and tools, as well as the special tools, can also receive the Repair enchantment, which lets them recover durability over time.

Mob Drops
Thaumcraft has several new monsters, with new drops.
 * ../Angry Zombies/ (and their big brothers, Furious Zombies) drop zombie brains, which can be broken down for essentia or (for advanced players) crafted into a Brain In A Jar.
 * ../Wisp/s drop "ethereal essence", which is otherwise available only by breaking a node. These precious items (each imprinted with one of the 50 aspects) can be used in magical crafting, or broken down for essentia -- in addition to their visible aspects, all ethereal essences contain the rare Auram aspect.
 * ../Thaumic Slime/s drop "tainted goo", as do certain ../Taint/ed monsters. The Taintacle also drops "taint tendrils".  Both of these are difficult to collect, as after every 45 seconds in a player's inventory, one will dissolve (infecting the player with taint status).  However, they can be stored in a chest, or a donkey's or mule's pack, and will not decay there.  They can also be tossed through a magic mirror, or brought home by playing "hot potato" -- dropping them and picking them back up every 30 seconds or so.

Wand Foci
The beginning player may be frustrated with the few uses for wands. Using them for crafting and building is all very well, but where are the wands that go zap? For that, you need to get hold of some Nether Quartz and craft wand foci. The several types produce a variety of offensive or utility effects, powered by the vis within the wand. Wand Foci can also be enchanted with a number of focus-specific enchantments to improve their performance. They can even be enchanted on the vanilla enchanting table, but note a bug: High-level enchantments will frequently give them Unbreakable, which is useless for foci and makes infusion enchanting them afterwards that much harder. You can also craft a Focus Pouch which stores all of your wand foci in one inventory space, and allows easily switching among them.
