When leveling up, I aimed for "Fury of the Elements," and I invested in Logistics and Machine Management.
Usually, in a battle with him, I do the following.
My warriors naturally go first, with the first move being with the Furies. I used them to attack the Emerald Dragons, then my Black Dragons moved, and I continued to attack his dragons. Of course, my dragons died immediately, then I attacked the dragon with the Lizard Riders, and then I finished him off with one of the archers. Then I started dealing with his archers. When I killed them, I took out the Dancers and Elves. Since the Ents and Unicorns are large creatures, I surrounded myself with a Wall of Swords, and it takes them several turns to break it, so I shot them down.
By the way, I appreciated that a large part of the quest elements on the second map were taken from Gothic 3. Is the author a fan?
I'm also a fan of Gothic, but I didn't see anything similar.
