Island of a small skull

An interesting map; I've never had such a large army for a hero before. I didn't even need to level up the Necromancer to get Liches. Sandro was defeated without any problems; I could have done it a month earlier, but I decided to increase the army size a bit more to ensure a decisive victory. I'm posting a screenshot of the battle. The last battle for the Necropolis castle was without any losses; no one even had time to attack me :D. The main hero is level 58, and that's not the limit for this map.
Thank you for the map; Sandro didn't need to be weakened, or at least not so much ;) .
