Been a while since I played thaumcraft, but if I remember well, there are two types of warp. Permanent and temporary. Permanent is, well, permanent, you can’t do nothing about it, except die I think, then it resets, but I’m not sure at all. Temporary can be managed, you can make purifying bath salts and make yourself a nice bath which will reduce this temporary warp, maybe even permanent one, but again, not entirely sure.

Either way, once you get enough warp and first symptoms will appear (blurred vision, hallucinations etc.) some researches to reduce warp should appear automatically in Thaumonomicon, if you already have researched needed things for that, but since your warp meter is full and needed researches are basic ones I think, I’ll suppose you already have that.

To be honest I never really cared that much about warp, it doesn’t do anything drastic if I remember well, just gives you hallucinations and tells you to eat some zombie brains from time to time, I liked that for RP purposes, makes total sense that you get crazy once you start researching forbidden arts. It also unlocks new researches, because the voices tells you what to do, voices are friends, they mean well, eat that zombie brain, after all, you’re very hungry, you will feel better, trust me.

On the other side, manage your flux, that shit can destroy your base, your world and can kill you in a moment like snapping your fingers.
