What is your opinion about neutral creatures?

But if there were initially about 500 of them, then what? :) Secondly: I meant 20 nearby, :)

How much time would it take for the number of monsters to increase to 500, and the Necropolis army should be of the same size. And how could you allow 20 creatures to get close to the hero?

Well, if it's done remotely, then 2 monsters, each with 30 units! Cast on both of them?! But if it's just a regular Necromancer, say, level 20, then what!? Will they pretend to be dead?! :) :)

First, one squad at a time, -13 units, and cast twice - almost one squad is gone. And then, improvisation.

And do they have good morale?! :)

Well, it's a long way to go. 3-4 moves.
