The scenario "Last Flight".

I played like this: with my starting army, I started clearing the map to the left, where the quarry was still located... I chose skills from the skill wheel that were useful for summoning Urgash and also luck. Gradually, I built up my Castle, but I didn't build Devils or Capitols at first. As I gathered my army, I cleared out the entire Dungeon. I didn't touch the Portal. When I ran out of money, I built a Capitol. I took the Outpost and Abandoned Mine as the very last structures in the Dungeon. Then I decided to scout what was in the Portal. After clearing the upper part a bit, I ran into Miv. I summoned an army from my Castle; everyone came to me except for Imps and Demons. I lost to Miv and had to retreat a bit. Then I decided to build Devils, and the next day, Arch-Devils. I went back down to my Dungeon. Miv periodically jumped around up there. When she left, I went up with my slightly reinforced army and cleared out everything up to the garrisons. I went back down for my army again, defeated the right garrison. Miv is not responding or is temporarily unavailable... I ran through the garrisons, brought the army to the Castle, and defeated her. That's it. She was level 13, and I was level 18
