Salt is incorruptible and as such has remarkable power to ward off unclean spirits. Legends tell it was such an important substance that giantesses would mill salt before gold.
It is used to protect infants from abduction by changelings, humans from possession, corpses from demons, and just about anything from fell magic.
Just as it absorbs moisture, salt also draws evil from many monsters, causing great pain and weakness. It can also draw bad luck from a thing or place. Inversely, it can be used in malevolent magic to blight fields and livestock.
The most effective salt is blessed by clergy, collected from sacred springs, or scraped from witches’ salt-kettles. The would-be hunter is advised to carry and use salt liberally.
Salt is particularly useful against ghosts, witchcraft, djinn, and corrupting wyrms.
