Amulet of Submission

The Amulet of Submission is a Gargish artifact signaling the wearer's willingness to be the victim of ritual sacrifice. It appears in Ultima VI

Description
After learning of the Gargoyles belief that only the sacrifice of the False Prophet could save their race, the Avatar would eventually consent to be put to death in the hopes of gaining time for forging a peace between the Gargish race and the people of Britannia. Draxinusom, after questioning the hero as to their willingness to die, placed the crystal Amulet of Submission around the Avatar's neck, marking them for eventual sacrifice and willing surrender.

Once it was thus worn, the hero proved incapable of removing it, and those Gargoyles who beheld the artifact around the Avatar's neck proved notably more civil and reverent regarding them.

Trivia

 * Not wearing the amulet will result in gargoyles either refusing conversation, or becoming outright hostile and attack.
 * While the amulet in Ultima VI blocks off the neck slot permanently, in The Ultima 6 Project it goes into a special slot, so that the Avatar can still wear another necklace.
