A Warrior hero from the Dungeon faction? That's absurd...

I think that the hero is largely determined by the size of the map. On small maps, it is unlikely that you will be able to take unconventional skills. Also, there is no room for respecing, and there is no assortment of artifacts, so you have to equip not what is best for a warrior, but what is available. More room for creativity appears on monster-filled maps created in the map editor. There are utopias there, and simply creatures that guard artifacts, possibly mentors, as well as random towns where you can learn spells from unconventional schools. By the way, the question of a warlock-warrior has already been raised somewhere. I will try to list what they came up with:

- The hero is definitely Kifrah, because of her leadership.
- Naturally, attack with retaliation is maxed out, and the speed aura is taken.
- If defense is available, it is definitely taken, and it is also a good idea to take Stone Skin as a perk.
- Only artifacts that enhance creatures are equipped.
- Education is not necessarily taken, as a lot will still go into magic.
- Elemental chains are maxed out - after all, this enhances the damage dealt by creatures. But you shouldn't focus on them during battle. However, this is obvious.
- Luck. Again, this enhances damage.
- In order for the stats that went into magic and knowledge not to be wasted, and so that the hero does not slack off during battle, summoning is taken, and then it depends on the situation.
- You can also max out logistics and go up to surprise attack. If the hero is Kifrah, then the minotaurs, teleported to the right point on the battlefield, will definitely cause a lot of trouble.

That's roughly it. I haven't tested this in practice, but in general, there is nothing supernatural about it, although there is a strong dependence on randomness - a lot of stats may go into magic, or, conversely, the magic power may be very low.
