Not yet. Just about finished all I can in the thauminomicon without making anything or scanning anything, got myself some iron and gold, a house and farms, and so on. Next on the list is diamonds so that I can get obsidian for a portal to the nether for some netherrack & netherquartz, and then I'll blast through getting thaumcraft set up for infusion etc.
I'm going to try to actually get void armour this time, because that's something I've wanted to do ever since I heard it existed.
..also I'm absolutely dreadful when it comes to combat. Just gods-awful. I prefer playing on peaceful, but I'm trying to stop that.
Anyway, I've mod suggestions: light level overlay (or whatever it's called, the one where you can hit F4 and see the light levels like you could with NEI), and gravestones (or whatever it's called, the one that made it so that, upon death, your inventory was preserved in a grave).
