To start this quest, speak to Wizard Mizgog on the top floor of the Wizard's Tower. To get to the Wizard's Tower, go to Draynor Village which is located just west of Lumbridge, then go south until you hit the coast. Cross the bridge, and you can see the tower from there. He will inform you that another wizard has summoned imps to steal his magic beads. He employs you to help him.
Recovering Mizgog's Beads
In order to return the beads to Wizard Mizgog, the player must kill imps to retrieve the magic beads. The four missing beads are:
Imps drop these beads randomly. Imps are only level 5, and have a maximum hit of 1, so no food should be required to kill them. Imps are scattered all throughout Gielinor. Popular imp locations include the volcano on Karamja and the area south of Falador. It is possible to get multiple amounts of the same bead, and thus players often spend large amounts of time killing imps during this quest. It is possible to purchase beads from other players.
