Make Witchery / Thaumcraft more useful about bikes6

[jamzss]

Witchery

• Attuned Stones are relatively inexpensive gems, but require quite a bit of random chance and processing of specific saplings inside a Witches Oven

• Koboldite Ingots are rare ingots obtained by trading with Hobgoblins for both nuggets and dust (81 dust = 1 ingot), but the dust is only obtainable by a Hobgoblin when they go digging, so this could be used in recipes more towards endgame

• Impregnated Leather has a reasonably involved crafting recipe, involving the Witches Oven and the Distillery

Thaumcraft

• Thaumium Ingots, if removed from all loot tables & loot bags, serve as a material slightly more valuable than iron, can be crafted relatively early on in normal Thaumcraft progression, and later have its production automated fully.

• Void Seeds can be crafted in late-game Thaumcraft, or dropped by Cultists and Crimson Knights with a 20% chance to drop 0-1 seeds, and Void Ingots are crafted in a Crucible using these seeds also with late-game and valuable essentias.

• Nitor is a very inexpensive crafting material, made by using simple aspects, or throwing torches, 2 coal and 1 glowstone dust into a crucible.

Several useful items from tech mods now require items from Witchery or Thaumcraft. If anyone feels that they should be used in more recipes, please reopen this issue.
