Actually, when I saw the topic, I immediately thought of the fifth game – that's where there are really races from which you can create both pure warriors and pure mages. In the third game, you can't do without magic, even for an experienced barbarian. I personally level up Wisdom and magic of some element for any hero. That's why I voted for the mage.
Once, I killed 25 black dragons on cursed land with 3 Archdevils without any magic at all!!!
