How can I change stuff granted by classes? Basically what I want to do is change the wizard/sorcerer linear spell progression to something more like geometric progression. I.e. you start out with much more spellpower and gradually gets less and less. Any ideas?
The thing is that the Co8 wants to make this game as rule compliant as possible, so don't expect anything to be done just for you. I think it's possible to add spells from the console but to change it in this way you'd have to edit the temple.dll (need confirmation about this one).
I was not expecting someone to do it for me, but to point me out which files I need to mod. Possibly which tools I need to do that too. Like in BG2 you need to mod MxSplWiz.2DA for example.
Maggit is correct. The spell progression by level is hard coded in the temple.dll. To edit that you either have to hex edit it or us a decompiler and have working knowledge of ASM.
