New era.

I'm stuck on the third week now, I've tried it several times, because I realized that I was spending too much time on the starting location and not going to the garrisons, each time I completed the catapult quest. Now I tried to be more aggressive, in the first week I cleared out some of the orc buildings at the start to replenish Gotia's army, almost all the hiding spots that are at the start near Zehir on the way to the Castle and at the gates. After that, I went with Zehir and Gotia to clear out the garrisons and later brought Frida. I cleared out all the garrisons (didn't have time before the first reinforcements arrived, but I did before the second), about half of the Dwellers, and the simple hiding spots that were along the way. But still, something is missing to at least be on equal footing with Shadowmancer, maybe I need to rush even earlier so as not to lose the first reinforcements, or come up with something with the build order. The map is quite narrow, caravans get stuck easily, and on the right side, I think, there is not enough a Shrine.

Good afternoon. There is a separate topic on the forum for this map, where those who have completed it gave advice. In short, I can say:
1) The number of dwellings under the enemy's control significantly affects the enemy's army.
2) General Kane can retreat from the battlefield. It is useful to level up him so that he can attack Shadowmancer several times and reduce his army with machines before he reaches the city.
3) Shadowmancer's specialization is countered by mages in the hero's army, who dispel the counterspell before the hero's turn.
4) If possible, destroy the catapult as quickly as possible when defending the Castle, so that the enemy's main units cannot break through the wall.
5) When I was playing, I tried to level up Kane and Zehir as quickly as possible. Kane reduced the army, Zehir defended the Castle. But I don't remember anymore which enemy hero I gave shackles to, and which one I didn't.
