Tactics for playing as the Dwarves.

How do you level up then! I'm completely confused!

I think that if you go through Chaos, the best build is as follows:
1) Chaos (preferably through pyromancy, then you have the opportunity to play well on Armageddon - you leave the dragons of the Jarls and the priests of flame and... cast, cast, cast...)
2) Leadership - Runic Harmony and Diplomacy - Empathy (because the morale of each squad is at least +7!!!, the hero will move almost like Oraz, and this is very important for Chaos, and it turns out that magic is not needed...)
3) Education - Magic Attraction (so that there are no problems with mana, and also Scholar - Keeper of Secrets (and +2 to witchcraft, which is nice for Chaos, and empathy cannot be opened without it)
Next, you can take attack with mass acceleration or defense with mass stone skin. Since there is no light, this will help, in my opinion, attack is still better. Or you can take both if you have enough levels...
In the end, you get a good Chaos mage, and also an excellent warrior.
And if you go through Light, then the best is the following:
1) Light - Righteous Wrath - Secrets of Light and Bestowing Protection
2) Attack - Tactics - Attacking Hirdu - Retribution
3) accordingly, Leadership through Runic Harmony and rallying troops to Enthusiasm.
Next, you can take either luck with soldier's luck (extremely useful for a dwarf - and the spear more often cripples, and the bear more often hits or scares with its paw, and some rune works more often...) if you choose an attacking option, which is preferable, or defense with readiness if you choose a defensive option...
In the end, you get an army of unprecedented strength, quite mobile, with huge defense and very good attack.
