The mages managed to achieve victory on the 13th day; it's a pity that they couldn't find any Boots of Swiftness anywhere, otherwise they could have saved another day. The battles went quite smoothly:
on the second day, victory over the Barbarian;
on the 3rd day, capturing the chests behind the Barbarian Castle, gaining experience;
on the 4th day, breaking through the outpost and reaching the right Castle of the Dungeon faction;
on the 5th day, capturing both Castles of the Dungeon faction;
on the 6th day, destroying the rearguard of the Dungeon faction;
on the 7th day, returning to the Barbarian Castle;
on the 8th day, destroying the remaining forces of the Dungeon faction and recapturing the Barbarian Castle (while the main hero fled to the Dungeon faction's Castle).
On the 9th and 10th days, the main hero marched into the lands of the Dungeon faction, capturing the first Castle and destroying two heroes. At the same time, all available forces were gathered near the Castles of the Dungeon faction, and three additional heroes were hired (bringing the total number to 7).
On the 11th day, the main hero captured the next Castle. Near the Dungeon faction's Castle, there were battles with one of the Dungeon faction's heroes, with three defeats inflicted on him, and a 4th victory, followed by the elimination of the second fleeing hero with a small army.
On the 12th day, the third Castle was captured, and the path to the 4th was cleared.
At the beginning of the 13th day, the main hero reached the last Castle and killed the two remaining heroes.

As a result, the most difficult part was defending their Castles with the secondary heroes. The battles conducted by the main hero did not cause any problems, because he immediately focused on learning and magic, so he crushed his enemies with his magic like a tank :smile14:.
It's a pity that he didn't have the opportunity to bring Fire Golems to the end of the game; otherwise, it would have been even more fun
