Imp Catcher

How to start
To start the quest, you must make your way to the Wizards' Tower which is located just south of Draynor Village. You must cross a stone bridge to get to the tower. Once there, enter through the front door and make your way to the top floor. Talk to Wizard Mizgog and ask him questions. He will tell you that imps have stolen his magical beads and needs you to retrieve them for him. The beads he needs for you to get are:
 * A black bead
 * A red bead
 * A white bead
 * A yellow bead

Obtaining the beads
The beads that you need to get are only dropped by imps. Imps can spawn almost everywhere in Gielinor. The best location to kill imps are at the Karamja volcano due to the high imp population, but it can also be dangerous to lower-leveled players due to the scorpions that wander around. The beads are among one of the few quest items that are actually tradeable and due to this, you could buy the beads from other players rather than having to kill several imps to get all four beads. It is possible to shorten the length of the quest by obtaining the beads before starting the quest, and then returning them.

Returning the beads
Once you have collected atleast one of each four colored beads, you must now head back to the Wizards' Tower to give Wizard Mizgog his beads.

Congratulations! You've completed this quest!
