I won't swear, but I'll say a few words about the Arcanum units to keep things interesting. This type of unit should generally stay at home, but it definitely shouldn't be the last one you buy. If things are such that you're dragging your units across the map, searching for resources, and afraid of encountering units like Archmages, Druids, Priests, and Archers... many of them will attack your units, and 90% of the time, it's because your units are weak. So, you should really think about whether you need to take them on an expedition. If the map has a lot of large melee units like Griffons, Djinns, Unicorns, etc., then you can take them, but if they attack first, half of your squad might be wiped out. So, in my opinion, it's better to leave them at home and save up. And in the final stages, take Berserkers, as they surprised me a lot in a game against one player (after that, I started favoring them more).
