Make holy water turn into normal water when inside the same container as smoke powder

[UrsulaMejor]

does holy water deal flat or scaling damage on application?

if it is scaling damage, then really the only thing you need to worry about with smoke is that it reveals you as a vampire, which sucks, but vampire isn't really a stealth antagonist to begin with, and it's probably the second best eqipped antagonist to deal with being revealed
