Train Barbarian early. Like, as soon as you get ready to leave Valeia for the first time, if you've got the GP.

All you need are 20 kills, meaning that you have to strike the final blow. That can be challenging for a young party, but you'll get used to it. The fun part is that you can get those kills with anything, including cockroaches, rats, fish... you get the picture. Consider giving all offensive scrolls to the wannabe barbarian and having him or her use them.

Oh, yeah. IMHO, you want to switch to Barbarian ASAP to get the benefit of the HP. You tend not to gain a real increase in HP until you've surpassed your old level, so the longer you wait, the longer until you can turn him or her into a tank. It does average out over time, but personally, I'd rather have the big HP early instead of a former wizard getting a lot of HP later.
