After helping the Wizards of the Wizard Tower with the "Rune Mysteries" quest a long time ago, they have now built a guild to experiment on Runecrafting.
Two wizards in there arent getting along too well.
Pick a side and battle out in "The Great Orb Challange" minigame.
This video will tell you more about the minigame and show you the outfits you can get.
