Necropolis – “Misfortune never comes alone” [Campaign 2 – Mission 1]

Hello everyone! I'll tell you how I completed this mission. I played on normal difficulty, and the first time, I was defeated shortly after capturing the second Castle. I had to replay. I captured the first Castle, bought a hero there, and used that hero to gather resources for Anastasia. Then, Anastasia reached the second Castle, and the second hero brought her an army; the second hero himself started exploring the area. An Inquisitor ran out to meet him, but didn't quite make it; Anastasia arrived and defeated the Inquisitor outside the Castle. Also, the enemy hero left half of his army in the Castle, so it was easy. Then, we captured the Castle itself, moved down, captured the crystal mine, raised undead from the graveyards, and moved to the remaining Castles. The second hero ran out to meet me again, allowing himself to be defeated outside the Castle. Then, I bought the army that had accumulated in the Castles and went to the Dungeon to defeat the last hero. There, I didn't attack the neutrals to conserve my army. After defeating the last hero, I had about 150 skeletons, 30 ghosts (there were 170), and 10 zombies left. Then, I spent another 3-4 weeks building up my army and easily defeated the guy with the butterflies. The main hero had dark magic (weakness and morale reduction, both area-of-effect) and earth magic (mass healing) skills. I can say that building Castles was a major challenge. There was a catastrophic shortage of blue stones, so I could only convert the Castles at the end of the game.
