Last time we talked about this someone suggested there was an Area of Effect property to water blessing. Like you can't just bless all the water in the biosphere so that all vampires in the world get killed by Holy Water Vapor.

"Few creatures of the night have captured our imagination like vampires.
What explains our enduring fascination with vampires? Is it the overtones of sexual lust, power, control? Or is it a fascination with the immortality of the undead?"
Feel free to post any vampire-related content here. I'll be posting various vampire media I enjoy just as a way of kickstarting this community but don't let that stop you from posting something else. I just wanted a place to discuss vampire movies, books, games, etc.

Yes, vampires have existed longer than the Christian faith. The idea is someone with a high faith stat imbues a volume of water with holy energy. The higher the stat, the more energy gets imbued. This however does rely on what ritual is used and how well it's performed and of course the stamina and magic level of the person performing the ritual. The holy energy transferred also drops off with time, this is a logarithmic curve. So a high amount of energy drops off fast, where a lower amount of energy can stick around for a while.
The volume of holy water flasks isn't just arbitrary chosen, it's the exact right volume for a common priest to imbue with holy energy and have it stick for a practical amount of time. Now remember the holy energy doesn't really do anything to vampires, sure it burns and hurts them, but they are eternal beings not pussies. It won't cause real physical damage, at least not any meaningful amount. So it's best use as something akin to pocket sand, something to distract and annoy vampires with.
Some monsters other than vampires are susceptible to holy damage, but many aren't. So the practical use is limited. In theory you could get a bunch of priests together and have them bless like a firetruck full of water. But no group of vampires would be caught out in the open like that. They employ guerrilla tactics, not open warfare. Plus the rituals will get in the way of each other, so the energy transfer is actually very poor.
Honestly this is basic stuff, the local library has many books on this very subject. Ask your local librarian for something like Hal's tombes of magic part 2 and 3 or Abbacula's collected works on Divine Magic, it's all in there.
Or like a wise person once said: You'd be surprised what a shoulder mounted rocket launcher can kill.
Just have a priest bless the water at the church, which everyone then drinks. Now everyone who goes to church has rat poison in their veins.
Does this make the church members' pee holy too?
What do you think communion is?
It is not like the sprinklers use a specific reservoir of water.
Some do. A reservoir on a roof, often enough.
Couldnβt you just bless the local reservoir? Or the rains like they did down in Africa? I heard thatβs how they fixed the Vampire problem there
TIL Africa has been vampire-free since 1981.
What evidence do you have otherwise?
Not mention how would a teenage girl get enough holy water for whole sprinkler system?
Or how often is there a somewhat planned attack where multiple vampires are inside one building?
Not mention it would probably would just work the first times then vampire would not be inside or just wear umbrellas and rain ponchos.
If you pour a couple ounces of Holy water into a gallon jug of regular water, is the resulting water all Holy?
Supernatural made some consideration regarding this and similar questions.
Holeopathic water treatment.
Or how holy is the water by parts per million?
Only effective against homeopatic vampires
Since god is everywhere, wouldn't all water be Holy?
Donβt quote Hindu scripture to me bro.
Most places vampires hang out don't have sprinklers, notably the graveyard and various crypts and tunnels.
They did in that one scene from Blade
New Order - Confusion (1995 Pump Panel Remix)
Absolute Banger!
Also solid contender for best intro scene to a vampire movie ever. Likely top ten action movies IMO.
