Which faction poses the greatest challenge for the Dwarves?

I agree about the logistics, but only if the map is large or very large; if it's huge, it's really necessary. In other cases, you can do without it, but opponents who focus on movement can be a problem, although they aren't a problem on small maps. I remember one time, a Necromancer was sending armies from two castles, but only with units of levels 1-3. I lost, but I realized that in such cases, it's better to develop Light magic than Chaos magic. There was a lot of meat, especially the Messengers and the remaining Zombies at the end, which were protected by the Celestial Shield. I defeated the rest with Chaos magic: Pyrokinesis + Fire Sign + Priests + the hero Erling. The Fire Sign looked very good on the Ghosts, of which there were quite a few, around 200 or more. But the enemy didn't have Vampirism, so they didn't heal, and they died under the fire wall and the hero's fireballs. And at the end, I successfully defeated about 60 Spirits with the Priests' shots. Dragons and Jarls held back the Messengers and Ghost Dragons, and blocked the Liches. Vampires fell under the shots of the Throwers and the stunning attacks of the Bears. If the opponent had summoned more units, levels 4-7, I would have been completely defeated. But as it was, only 400 or 500 Zombies remained. There were about 1,000 of them. The Zombies' attack of 40 against the Jarls with Luck was especially brutal. Ugh, what a sight. BUT: there were no runes of Battle Fury and Invulnerability, which could have changed the outcome of the battle. Well, that's all!
