This playthrough was on normal, I will do one on hard. I do not mean to belittle the OPs difficulties, but we are on the internet. I am not a handy guy and I once installed a new light switch thanks to google. A quick trip to these forums, a quick trip to google, some thought put into spell combos...yada, yada, yada... it's all here.
I played on hard from day 1. While you can sure get yourself in a pickle if you approach a fight wrong, I wouldn't even call Hard really that "hard". I guess it all depends on how you design your characters, how you approach a fight (using your surroundings to your advantage with choke points, environment, etc...), but I think a large percentage of the difficulty with this game is learning to use the system and actually applying it.
