aipok: I recall level 14 being around 32k xp. There are probably ways to just farm, although, to be honest, you don't really need to max any skill to beat the game, at least in normal. As long as you can deal some damage, is more a matter of patience than statistics.

This. I finished the game and my characters were level 12-13. Camping to level up seems possible in a couple of areas, but seeing how xp requirements increase every level, even those areas seem like a place where it would take ages to get two skills to level 50.
