Pendant

The Pendant of Bandos is found in Bandos' throne room during The Chosen Commander quest. Zanik wears it, is possessed by Bandos, and will attack after killing Sigmund. After defeating the possessed Zanik multiple times (Because the Pendant revives her), the player convinces her to remove it. It is then put on by the High Priest (Goblin), creating the Bandos avatar. It is eventually destroyed by Zanik and the player at the end of the quest.

There was a glitch on the first few days after The Chosen Commander was released where you could keep the pendant after the quest.

Trivia

 * Players cannot wear the Pendant.
 * The fact that Bandos put much of his power in the pendant to control Zanik, and when it was destroyed, his powers were permanently crippled, could be a reference to the One Ring of Power, in which Sauron also put much of his power, and he was almost destroyed when the Ring was destroyed.
