OK, thanks.
Then I definitely think that playing a wizard is totaly absurd.
I did a huge mistake.
Wizards' almost only advantage is their spell points, and they don't really need it, a few charms do the thing, and they lose on everything else.
I guess I'll start over for the 4th time, and this time play a fighter. He'll get all the skills he needs from books to cast spells, and be a killing machine.
Really can't see the point in playing a wizard, apart from the beginning of the game, before I get extra points from charms
