Holy water

Holy water is water that is blessed by a priest. It can be found in nearly any Christian church and is used in various observances of Christian tradition. Holy water is also known to be anathema to some forms of supernatural creatures; in particular: demons and vampires. Anointing a demon possessing a mortal with holy water will cause the spiritual entity great pain, often driving it out from its host form. A vampire who makes physical contact with holy water will suffer from severe burns.
