So here is a question - by definition (as far as I am aware) all of the most extreme creations are sustained by vitae due to being so far removed from the human condition. But how does some elder Fiend feed their dozens or hundreds of war beasts or amenities?
Everyone can parse how one Tzimisce would feed a pair or trio of szlachta - but the advanced fleshcrafters have buildings made of flesh that will die unless sustained by vitae, since a person spread over 20 feet or so to become wallpaper cannot reasonably live without magic. Extrapolate this to a whole haven or kennel of ghouls - how on Kupala’s Great Earth do even advanced fiends manage to A) procure enough vitae to sustain their dozen creations who aren’t actually self-sufficient; and B) not lose days spent in maintenance (although the image of some depraved monster spending a couple of days a month wandering around their haven, tenderly feeding their chairs, pets, and pet-chairs is engaging).
I’m aware in V20 Lower gens have deeper blood pools, but even a 20 point pool is extreme and would need topping up to keep everyone/thing ghouled. I’m also aware that entrenched fiends can be VERY efficient in the production and procurement of blood (looking at you, comatose bloodbag hung from the ceiling). But this takes an old monster to pull off, and even then is a full time job.
So outside of extreme cases like Yorak or Vykos, how do they do it?
