Can someone point me to info on how taint spreads? Googling turns up mostly Thaumcraft 2 info which is not terribly helpful. I've gathered from this thread that it can't occupy the same space as ladders or torches, and I get the whole pure node and ethereal bloom thing as I've played at least that far with Thaumcraft before, but I've always been super careful and not had to really deal with it before. Can it jump across spaces if the biome is Tainted Land? I have two pure nodes sort of near each other... if I build a base in the air and connect the two spots, will I get tainted stuff spawning up there?
Funny thing -- I've always been terrified (see above re scaredy cat) of dealing with a Tainted Lands biome at all and now I'm walking all over one, willy nilly (and dying from time to time but oh well).
Last night I tried building a hobbit hole with the old "can't spread across man-made blocks" thing in my head. That is either no longer true or it needs to be a thicker barrier of man-made blocks. Fortunately, pure nodes had started to spread enough to be visible by then, and I made a new base-home as a little cobble platform directly above one of the pure spots (and encased the node carefully in cobble so I don't accidentally hit it.) I'm not sure how much I can expand it, though, or if I should build vertically until I can get some farms going, hence the questions above.
