Metal Collar, inscribed with runes and numbers(1-7): Each collar acts exactly as the "Dominate Person" spell, except with no saving throw. As long as the collar is placed onto an intelligent being and the command word spoken to lock it, the target wearing the collar is under control of the user via a telepathic link. For every day this collar is worn, the person who spoke the command word has to make a DC 16 WIS saving throw. Upon failure, the collar comes off, and is un-usable for 24 hours.
