Hi all i have done it after 40+ hours to finish the game with 85% solved secrets and so on.
But i have to say that after lv25 i had no hard time playing exept in dragon form.
I was a warrior with this stats:
Vitality:91
Spirit:4
Ineligence:1
Dexterity:3
Strenght:83
Well, with such high vitality & strength it's no wonder...

I played as warrior too but raised dexterity & intelligence until they were at "normal" levels... I didn't like my 'hero' to be dumb and clumzy.
