Inside Atoll of Immolation

There is no set entrance for Atoll of Immolation.  Once inside, you will battle through a few mobs to reach another portal.  Using that portal, you will be transported to another smaller inner island.  You will find more mobs and a mini boss that will be random.  These bosses include Domoira, Faram-Xaran, Flarion, Kmolag, and Ol’icath.  After the mini boss, you will use another portal to another small island.  That island will consist of mobs and Salosuum.  After defeating Salosuum, you will enter into Havocrel’s Tower and ultimately find Havocrel Duke of Storms.  Defeating Havocrel allows you to deactivate the antecedent cataclyst allowing a treasure chest to appear.  You can exit Atoll of Immolation by using another portal.
