Can someone give me a very quick rundown of what thaumcraft does?
Thaumcraft is not something that is just quickly explained. At it's basic lvl it adds magic to teh world in the form of nodes, crystal shards, auras, wands, magical constructs like golems, magic spells, and magical items. Almost every item in the game is made up of magical materials called aspects. You break items down into these aspects and use that to learn research, and to make things like wands, golems, magical blocks, ecte ct. It is a very in depth mod that keeps getting added to and developed even more. It is a ton of fun and well worth the effort of learning about. Here is a pic of my thaurmcraft stuff in my base. I am going to be building an actual room for it later but this gives you some idea of how complex it can be. The last one is a picture of my thaumonomicon, which is where your research discoveries go.
The big grey block with purple writing in the center is my arcane stone. It is used to make magical items. It can also make mundane items as well. The dark grey block in the center in the back is my crucible. It has a block of lava under it to heat it. When it's hot it bubbles then you throw items in to release their aspects into the air for the arcane stone to absorb to make items. If you release too many into the air bad shit, like wisps spawning and trying to rape you, start happening. The green block on the top left is the arcane worktable. It is a smaller version of the arcane stone but doesn't use aspects from the crucible. The table to the far left is the research table. This is where you will use items to do research that goes into your thaumonomicon. (Note: the block on the right next to the water is not part of thaumcraft. It is a soul forge and is used to make soul shards that are used to capture mob souls and when you have enough they are used to make mob spawners. really neat mod)
thaumonomicon
Forgot to mention but if you look in the bottom left of all my screen shots you will notice a gauge. That is from thaumcraft. What that does is tell you how much magical energy is in the air and how much bad shit, flux the capital F, is in the air. The more flux is in the air the worst things that spawn and try to kill you hehe As you can see I have a lot of flux around my base atm but I will be fixing that soon. Also the larger the number beside the A, stands for aura, the more magic there is around you for making things. If there is no aura then things like wands don't recharge and you can't make magical items.
