The Wizards' Guild is a guild dedicated to the Magicskill. Players will need to have a Magic level of 66 or above to be able to enter. A Wizard's Mind Bomb can be used to boost to 66 or higher and enter, however, players are not able to exit through the door if their Magic level drops below 66. Fortunately, there is an escape ladder in the basement designed for emergency exits.
