ADiavola, you'll have to replay the mission. I immediately gave the joined dragons to Isabella. Even on a hero and without dragons, Markel easily defeats everything. The main thing is to curse at least one city as quickly as possible.
Listen, I didn't curse ALL the cities. I captured the first one, somehow cursed it, I didn't even understand how, and the rest remained Titan cities...
In principle, it's not necessary to do this. That's what I think.
