May or may not be the same as Blessed Water.
- "Behold the sacred water burneth the flesh of the Undead and causeth them to recoil from thee."
- —Extract from the Great Book of Banishment[2a]
Holy Water is produced when a phial of common water is blessed by a priest, typically of Sigmar, Ulric, or Manann. When splashed onto an Undead creature, it causes serious amounts of damage. Because of this, holy water is often carried by Witch Hunters.
