De Vocatione et Ligatione

This grimoire details a rite in which, after a successful summoning, a bracelet is enchanted with daemonic power to create a defensive charm shielding the wearer from mortal danger — with the caution that once the item has served its purpose, the entity within goes free.

It adds, citing the ritual of Apsethus the Libyan, that daemonic entities are not always the forces of evil and destruction that many scholars claim.
