On his ninth birthday, when the heroes apart from Bobby are kidnapped by lizard men and locked in the Prison of Agony, the Dungeon Master gives him a gift. It is an amulet that will protect the wearer from Venger and his sorcery but he also guides Bobby by appearing on the glassy surface and speaking to him from time to time, explaining that it is "a gift from me to you. A gift that will protect you from Venger, but remember this; its power is in the giving not the keeping. When you need its protection most you must give it away." Remembering these words Bobby gives the amulet to Karrox so that Venger cannot extract revenge on the giant or his homeland.
The amulet also protects Bobby in a more mundane way; by simply reflecting a lizard man who was creeping up on him.
