Stop random spell, and indeed add spell to reseaching tech.
Ok, that's is my goal to mod, but I'm not that good, but I will try unless someone beat me, I had a look at Corespells in english in date folder, I wonder what do "<IsResistable>1</IsResistable>" do?
Edit: Oh, I'm not sure, not only Corespell but could be other file as well, How do I ensure magic tech not random anymore and add spell to it? Like remove spell from quest and add it to magic tech? How do I go from there?
