Necropolis versus Academy.

Hi everyone! I decided to start a new topic that, as far as I know, hasn't been discussed in the Necropolis thread yet, namely, how Necromancers can defeat high-initiative Academy heroes in the late game. Especially if all artifacts are available, there's a mentor, and several months of leveling up have been done. I'd like to hear the opinions of experienced players on how to level up against Haven or other factions on large maps in a one-on-one game. If the Necromancer has several castles, the problem solves itself, but if there's only one:confused: I think this is one of the most challenging matchups. So, please share your thoughts.
