Twilight of Darkness

No one attacked in 2 out of 3 cases (all times with Necropolis). The hero "hesitates" at the point, then can go and take the book.

Exploring the map led me to the conclusion that it is easiest to play as Necromancers, and most difficult as Orcs. (By the way, only by playing as them can you get into the "Hall of Fame" and earn points.) Orcs play with only one castle: it is inconvenient to combine them with inhabitants of other castles. And on this map, the "melee" part is decisive. Losing Cyclops is very detrimental to them. Also, their magical abilities are limited (and already meager for Barbarians): everyone else in each castle can learn something, but Orcs can only do so in their one castle.
I cannot say that Necromancers are devoid of Dark magic. I was playing as Necromancers specifically for the "revival of darkness," which is visible in the demos. The absence of "Berserk" and "Dominate" is not critical with such possibilities for replenishing the army. The main thing is that all mass spells are available.
