Please advise on how to complete this mission. I've been trying for a week, but I can't seem to do it. The red player keeps attacking and attacking, and the orange player joins in too.
Antoha is already a mega-tank in the 4th mission. There shouldn't be any major problems. I completed the entire mission without any problems just yesterday on normal difficulty. I defeated Arriban without any losses.)
The strategy was as follows:
1. First, capture the first city offered. Then, capture two nearby forts (one of them has a crystal mine, which you need to capture after the fort) and one city required by the scenario for rebuilding, which is an Inferno city out of four, and immediately rebuild it for yourself. We kill the neutral creatures encountered along the way, but it's not worth running too far behind large groups of neutral creatures, unless it's for super-rare items or mines. All resources after the neutral creatures are collected by your helper: Lord (if you chose the path of tears) or the Traitor Valeska (my assumption) if you chose the path of blood. They should have their economy and logistics fully developed.
2. As soon as you have a foothold in these 4 areas, buy a secondary hero who will follow you and collect everything (I bought the one that gives ore) and gather all possible troops in the main city, and Antoha with the secondary hero go to the Dungeon. The secondary hero, through training with Anton, fully develops management, logistics, stealing, and pathfinding.
At the bottom, we go in a circle, capturing one Rampart of the demon worshippers after another. None of the battles caused any difficulties; almost all battles were won without losses. The damage from the area-of-effect spells of the enemy hero or the main unit of the demons is neutralized by having 2 stacks of Vestaloks, Seraphims, and Mass Healing. I didn't pay much attention to the orange heroes running behind me; they didn't go up. The worst thing they did was recapture their fort, and by that time, I had already taken all their castles. When the circle is closed, Anton finishes off the orange forces; the computer doesn't have enough intelligence to constantly run away.
From above, of course, the red heroes arrive, but they are not so scary at first. The Lord, who remained in the main castle with the joined units of water elementals, light elementals, core griffons, and, if necessary, purchased main troops, defended against their attacks in the open field.
There shouldn't be any problems after that. If you play confidently, go to the center of the Dungeon; there will be a strong enemy (in my case, the threat was fatal for Anton, but I defeated him almost without losses, losing 40% of the Vestaloks and about 20 upgraded guards; the "Guardian Angel" skill at level 4 is simply overpowered). Get the Tear of Ashi, teleport to the capital, and build an altar; in the end, you will have a lot of money... And then, just go across the top, counterclockwise, capturing forts and castles from the red player, ally with the yellow player, and don't pay attention to the neutral creatures on the side at all; just don't let the red heroes pass (you shouldn't leave them). The Lord holds the capital and the surrounding territories, and Anton with the secondary hero runs around and clears everything. The secondary hero collects the small things and reveals the map... In the captured cities, we buy troops as needed.
We kill the green player (I don't even know why he appeared; Svetlana only started talking to me at the end of the mission after killing Arriban). Then, we buy troops and clear all the neutral creatures if we want to upgrade the dynasty weapon. Anton should already be at the maximum level by that time.
