Let's see, I saved a lot of skill points until I got to level 24, but at least putting 1 on each just to get more, and to experiment. I focused on the martial arts. They will help you out a lot. Just remember like a sorceress try to give yourself plenty of energy points. Those are about the oly spells I use, the traps take too much skill levels to make them worth you while. You Shadow Disiplines" are also good to increase, just don't spend too much on the spells that summon a copy of you until you can get the last one, because you'll nevel use them again after that.
