Firstly, vampires cannot be bought; they can only be hired. Secondly, you can create a dwelling where they can be hired. The main thing is that it shouldn't be in a castle. We are truly neutral in nature; each vampire, at best, believes in the gods they have chosen, and more often, vampires are atheists. So, they don't belong in any castle. And werewolves are also good, and as neutrals, they are simply necessary, in my opinion.
No one is going to make a mod; all of this will remain only in this thread. So, what are we talking about? Why all this pretense with calculations about life draining? This thread already contradicts Heroes because, in this game, vampires are not as god-like and invulnerable as many people here imagine. And what is the point of the argument in this thread? And "race" is spelled with one "s."
