The thing is if, You start a Int, Will & Char toon, you have to immediatly have to train up on endurance and strenght, so you can accualy hold more then the armor you wear and walk further then to the tavern and not need a breather. See trades arnt officialy effected by stats I do not believe, but this is untrue, there is no way a int etc toon can carry enough to be a miner, Metallurgy worker or a smith, but chars that have rougly the same intelligence as the ammount of fingers they have can train up in all of these jobs, as well as Alchemy, err... paintng apprasal? And all the other heavy brains jobs there are......
So if you want to roll a mage of some kind, be sure you start with strong strenght and endurance, and level up with swords and make money, instead of rolling 105 or so int like I did and breaking many, many keyboards.
Mumble mumble groan groan!
