In the second restart, Dugald appeared in the tavern, and in the third playthrough from scratch, I made him the main hero. Dugald is our guy. In the second week, Kaspar emerged from the darkness and immediately disappeared again. I had to chase him. In the field, Dugald tore Kaspar apart with the army he had when he came to Rupert, losing 10 archers and 20 peasants. The Demon reluctantly appeared only at the beginning of the third week. Nimue brought 8 devils, about 10 cave lords, and other minor units in proportion. I had to take refuge behind the walls. The battle lasted less than four turns. Any stack of demons was destroyed in almost one shot. The morale of the archers (without leadership) was extremely high; Rupert didn't experience that in a dozen battles (with leadership). I was surprised, but after the first battles, the computer changed the Necropolis and Demon heroes. Then, Grog and Ravenna started coming to the Castle. The dynamics of the attacks changed. If there was a queue forming to attack Rupert, and everyone attacked almost simultaneously, Dugald is worn down: two enemy heroes appear per week, hang around nearby, and then attack. My main hero cannot move far from the Castle; it is difficult to defend in the field.
I've been playing for over 3 months, but it's heading towards a loss. The main opponent turned out to be the Necromancer. He has a lot of troops, a higher growth rate than the Humans, you can't get artifacts from him, and his magic power is already around 30. The losses from the battle with him are very high, and on top of that, they are constantly attacking the Castle/Capitol. I can only train peasants.
The conclusion of the above: Rupert's special ability needs to be changed.
