I also decided to play for a quick victory – I just went and defeated the opponents, and I chose Debilka as the main hero – I completed the map in 20 days (Debilka reached level 14).
U/S – a great hero. The opponents were barbarians, humans, and necropolises. It was unfortunate that I had to fight the barbarians first; as a result, after winning and capturing their castle, there was no opportunity to acquire offensive spells (I didn't study in my own castle because I left it before creating a guild of mages to save time). As a result, I had to wait for reinforcements from my castle to storm the next castle (necropolises) – otherwise, there simply weren't enough units to survive until Debilka's plasma cannon did its job, which caused me to lose a couple of days. Another day was spent hunting down the last enemy heroes from the dungeon.
