Rune to Preserve Your Health
Dabrinos, Amibiel, Cabarim, and Manador are four aerial spirits (sometimes referred to as great dukes, or simply dukes) who serve Demoriel, the demonic emperor of the north. They can be invoked for specific purposes, in which case occult-world dot com recommends that you “retire to a private and out-of-the-way place so that [your] experiments with his manifestation will remain undisturbed.”
I would advise you simply place this rune on your home altar, hang it on your wall, or, as "The Veritable Key of Solomon" (from which this rune comes) advises, tuck it into your horse’s saddlebag so you’ll have its protection with you wherever you go. God knows it's something we all need these days.
