VAMPIRES

Interactions with holy water:
 
Vampires are seemingly allergic to most holy symbols, including holy water, which will burn them cleanly through most flesh and bones, i have tested with around a drop burning through at least 4 inches of facial muscle and skull bone of the supernatural.
I have not tested potency in relation to effective caustic ability, but i will provide updates to this section if i learn more on the topic. “Tactical baptisms" seem to be safe and effective for mortal-vampiric conflict resolution.
 
Interactions with piranha acid:
 
Piranha solutions are a mixture of concentrated sulfuric acid (H2SO4) with hydrogen peroxide (H2O2), usually in a ratio of 3:1 to 7:1. They are used to remove trace amounts of organic residues, such as photoresist, from substrates. The mixing procedure is an exothermic reaction that can reach temperatures of 100⁰C or higher.*(1)
 
Knowing that vampires are still organic*(2) matter despite their undead/magical state, piranha acid will melt their flesh from bone in around 10-40 minutes, depending on the BMI of the subject.
 
Here’s some recipes:

1*please exercise extreme caution while working with piranha solution, as it has a very violent reaction and may explode.
