Haven faction discussion.

There are no problems with building a castle or creating powerful stacks; the question is which abilities and skills to develop for the hero, not the quartermaster, but the combat hero. And here I get confused, my eyes run wild. In theory, Leadership is good, more double turns, more Guardian Angel. Logistics is also clear, Tactics is most likely a must-have, and then what? Magic? Ranged attack? Defense?

Tactics is a must-have in the first place; max it out in subsequent turns when facing serious opponents; Tactics is everything.
Ranged attack, we only have one archer (more correctly, a crossbowman) at levels 1-2, and he already attacks the entire field.
Max out Counter-Strike; defense is our second priority.
Endurance increases the maximum health reserve by 2%.
If we are playing a mage, we develop Light or Earth healing; we can develop both, and don't forget to increase their magical power with special abilities in the Light and Earth branches. Also, don't forget about mana; there is a separate branch for it in Primal Magic. In it, you can also increase the hero's overall magical power and magical defense.
A good skill is Ambush, which gives +5 initiative at the beginning of the battle. Reinforcement increases the total number of creatures by 1-2 levels; we develop it when we need to fight serious opponents.
Among the battle cries, you can develop Heroism; it is now cast on all characters, mass, instead of a specific field as it was in the beta. Also, a good battle cry is Push Back.
We develop battle cries for the hero's warfare skills, of course.
We develop Charismatic Leader and Chosen of Fate for characters regardless of their affiliation; these skills increase morale and luck, respectively.

P.S.: This is the kind of description that needs to be done; you can't write it in 10 minutes. As soon as I play the release version of the game, I will definitely describe the tactics and development of the Alliance of Light in more detail.
