1.To start the quest, speak with wizard mizgog who is located on the top floor of the wizards tower. You will find out that a bunch of Imps have stolen his beads and wandered off with them. Tell him you will help find his bead.
2.You must now kill imps until you collect the wizard's beads. There are 4 different beads you must find which are the red bead, white bead , black bead and a yellow bead. Note that these are not consistently dropped from the Imps so you may be killing them for a little while. You may also buy the beads from other players if you do not wish to waste time.
3.After you have collected all 4 beads head back to wizard mizgog and he will reward you for your help
the reward is 875 Magic experience and an Amulet of accuracy
