In Abrahamic religions salt was stated as being able to keep demons and evil spirits away. If one were to pour a line of salt around their bed for example, would a MGE Demon be unable to cross it or are they immune to it?
@TakingABreak2021 You make a good point. Perhaps because monsters are no longer evil the salt would not affect them. It would make for a comedic scenario of a demon or hellhound being unable to touch a man because he is surrounded by salt.
Also you would need to perform a ritual with the salt, simply having eaten it dosen't do anything. Maybe snail mamono would be affected by normal salt.
