Hi ya Kicka,
According to the forum at Larian,
A much greater influence due to class is the way secondary characteristics are calculated. There are a couple stats which are generic; everyone gets 20 weight per strength point and 300 stamina per constitution point. Other secondary stats are calculated as follows:
mana per intelligence point
Warrior gets 3
Survivor gets 4
Wizard gets 6
This is a great website for DD info. I found the maps and the info & tutorial lists particularly helpful.
There are also many threads on DD in the GB archives under RPG.
I loved this game, but it's been too long since I played it to remember particulars of how things work.
I do remember that you don't want to lose your pyramid stones and that in spite of the fact you get invited to the Castle fairly early, you really don't want to go there til you've done everything else you can.
I hope this helps.

and let us know what you think.
