Amulet Of The Spined

While wearing this Amulet, the wearer of it shall gain the knowledge of three Spined Devil secret names. These names can not be spoken aloud, shared, written down, or any other sorts of extending the knowledge of the names to anyone other than the owner. Once ownership of the amulet is passed to another, from either being willingly given or stolen, the previous owner will forget the names immediately.
