A leash for the conscripted

As you know, I study summoning rituals. But it is not enough to summon an infernal creature - it is important to learn how to keep it on a leash. Otherwise, it will break out - and then what? Bring me the bracelets of doomsayers and bloodthirsty madmen. Originally, they served to restrain these terrible creatures. By studying them, I will be able to make significant progress in my research.
