and regarding the topic, Necropolis also wins without losses) but everyone except the Dungeon has problems with the castle) well, except for Haven, it's a bit easier)

Against Necromancer on hero difficulty, I recommend Kifrah (empathy, luck, education, chaos, and attack)! BUT!!! if the issue will be resolved in the first 2 weeks, she is not suitable! she is quite weak at the beginning. Then, Vaishan is quite effective in all parameters (luck, attack, magic, chaos, education)!
