Wizard Mizgog

Wizard Mizgog is a resident of the Wizard's Tower and can be found on the second floor. Talk to him to begin the Imp Catcher quest. You will then have to kill imps which will randomly drop each of the four beads. During the quest you then return these beads to Mizgog, and then he will reward the player with an Amulet of Accuracy after completing the quest.
