My favorite challenge play through of SOA/TOB was a solo naked sorcerer. It was seriously awesome. Not just solo, but NO EQUIPMENT. You wouldn't think it's possible, but that's how OP sorcerers were in BG2. It wasn't even that hard if you knew the game back to front and planned it out. All it took was about fifty reloads on every tricky battle, lol.
I never played BG1 at all until recently (loved it), and now I'm wondering if a similar challenge is possible for BG1. I'd really love to do it, but I have my doubts. I've done some experiments, but I can't really picture it. The encounters are much easier than BG2, but even at max level, a sorcerer just doesn't have any spell diversity. One of the main tactics of the challenge in BG2 was skeletons + haste, which isn't even possible in BG1. Not to mention there's no Wish spell, which means you can't Wish-Rest during long battles. I'm not sure if the final battle would even be possible with such a meager spell collection. They would chew through your summons, you'd run out of Skull Traps/Magic Missiles, and...that's it. No protections, no nothing.
Has anyone else ever tried this play through in BG1? I'm doing some experiments to try and figure it out, but I thought I'd post and see if anyone has advice. Any help would be appreciated, thank you.
