A marble amulet is an item used only in the Creature of Fenkenstrain quest, although it can be obtained after the quest. It is found upstairs in Fenkenstrain's Castle. There is a bookcase in the west room. Players must search it for the Joy Of Grave Digging book, and he/she will also find the amulet. The marble amulet forms a star amulet when used with the obsidian amulet.
