[Generic Vampires] Why don't vampire hunters ever drink holy water?
gpt
Drinking holy water is actually a pretty normal thing. Some branches of Christianity say that pious individuals should drink a cup of it every morning.

Mind you, however, that holy water has salt in it. Depending on how much salt was added, drinking that and *only* that could be bad for your health. There are also health issues, due to how 'public' your typical holy water fount is. Lots of people have dipped their hands in it and the like. The holy water being dirty doesn't make it less holy, but it *can* be desanctified if it's nasty enough.

But say you're buddies with a priest and he's blessed the gallons of water in your portable potable tank. He still has to add salt, of course. But what happens after you drink it? The blessing of the holy water, God's blessing, is transferred to your soul, not your body. It ceases to be holy water and turns into plain water, while your soul receives the blessings it once carried. Unfortunately for you, Hunter, just because your soul is blessed, it doesn't mean a vampire can't drain your body of its precious bodily fluids.

As for garlic water, you're already diffusing the benefits of the garlic by mixing it into water. You'd be better off just eating a clove or two raw. And even then, the garlic would break down swiftly in your body.
