The Day After Ragnarok: One Snake Cult, One Ranger
When asked how holy water is made, one particularly humorous priest responded "First you take a kettle and fill it with water. Then, you put it on a stove and you boil the hell out of it!" While there is some doubt as to how it is actually made (most likely a series of prayers and requests for God's blessing), few people can question the results. Holy water is a very useful tool against the undead in the world after the Serpentfall.
Holy Water (Cypher)
Effect: When thrown at an undead creature, a vial of holy water will do its level in damage to the target and any other undead within immediate range. It may also be effective against extraplanar evils, as well as creatures that are bound to them (such as some witches).
