Sometimes these old games make my brain hurt. Pick a secondary skill that matches your character's background and a complimentary NWP. It won't work at full efficiency until you get an official class. You may attempt to use any kind of weapon, skill, or other non-magic ability. Depending on how things shake out, you might end up with it. Your class or classes you end up with depend on your actions in the game. This could break the rules, but these are unusual circumstances. A human could be multi-class for example. No, there won't be any paladin/thief. There are still some restrictions. When determining such things as alignment and some classes, actions speak louder than words. Be true to your characters, but feel free to experiment a little try different things. If it looks like you may qualify for several different classes when the time comes, you don't have to take them all. If you have fighter and thief qualities but choose to focus on fighter, you don't keep thief skills and abilities.
