The Lord is more alive than dead

Magnificent, thank you for your feedback!

I have a question about Nicholas's specialization: is it really intended that there is no limit to the number of summoned units in one battle?

Yes, the number of summoned stacks is unlimited – the longer the battle, the more there will be. This is quite in line with the Necromancer's warfare style. And the size of each of them depends on how many vampires you have deployed at the beginning of the battle. And also on how much Nicholas is leveled up.

I might reconsider this.

And suddenly it turned out that I couldn't win without losses, because vampire units are summoned without limit according to the specialization, the battle drags on, and the game has already started to lag, loading.

I will increase the time intervals for the appearance of summoned vampire stacks – this should help.

I was defeating everyone without losses and problems using messengers under vampirism.

The problem here is probably only in "Vampirism" itself. Because with it, it seems, it's too easy...
