What’s the point of Kaspar, anyway?)) Personally, I used Ludmila (Blood Path) as a support unit. I completed the mission as described by Pobeditel in the first post; the main problem was defeating the demon in the castle, not necessarily defeating him, but minimizing troop losses. Although I bought them all back the next day. After leveling up Anastasia and getting the teleport, explosion, and slow spells, I defeated Miranda in 4 turns, simply by throwing 100 spider units over the castle walls.
