The reason people are told "mundane before magic" is so they remember to do things like check whether they've got mold or carbon monoxide in their house before they decide the problem is a malevolent spirit, find out whether their health problems have a treatable medical cause before deciding they're cursed, and make sure they have a mechanic check their car once they hear funny noises instead of just casting a safety spell on it and calling it good. People get hurt if they neglect the mundane.
