In Ars Rosaria: The Rosary Art of Conjuration, rosary beads are used in combination with adaptations of the Holy Rosary, a Marian exorcism, and various goetic conjurations to conjure and form pacts with the demons of Goetia.
 
Rosary beads are more commonly considered a devotional tool than a magical one, yet from a magician’s perspective they are unambiguously both, and can be used as a ward against evil as well as a means of ensuring that wishes will be granted.
