Justice is a three-part update between Advance of the Union and Tempest. With the Black Mage and his Commanders continuing to threaten the Maple World, Thieves and Pirates must rise up to do justice. It contains several overall adjustments, a Thief and Pirate revamp, and a new Hero class, Phantom. A new area is added, Azwan, where players must fight against an undead army.
This patch releases Azwan, an underground city that has disappeared and is under the control of the Black Mage. Players must battle through endless waves of the undead to earn Honor EXP and Inner Ability.
