I've done a lot of reading about kensai-mages and kensai-thieves (dualing at 9 or 13), in solo mode. How do most people survive the traps, and the lack of XP you suffer when you have no one to disarm them with? Would it not simply make more sense to have Jan around to unlock those things at least, or is the experience drain with a second party member too severe for someone who plans to dual at 13?
Also, when dualing, is the correct way to do it to level up to 13, and then get the benefits for leveling up to 13 (weapon pips, etc), and THEN press "Dual Class"?
What other strategies should I use? I plan to visit Watcher's Keep to buy potions cases, scroll cases, etc at some point.
Also, what weapon proficiencies are best? Currently I have two pips in two-weapon, three in long swords, and one in scimitars. I might put some pips in flails for Flail of the Ages +4 later, or in axes (unsure which). Ideally I'd want weapon proficiencies useful in both BGII and TOB (katanas, for example, cease to be useful in TOB given how several key enemies require at least +4 and there are no +4 katanas)...
