Anub ' arak ( tactics ) Anub ' arak is the third and final boss of Azjol - Nerub , an instance in the Dragonblight . Abilities . Heroic : Tactics . Shortly after the fight starts , a wall of web is raised around his platform which will lock group members out if you are not all inside . Be sure all party members are on or inside the ring before engaging . Anub ' arak requires the tank to get quite close ( near melee range ) before the fight begins and the web goes up . Warriors and Druids should not attempt to start the fight by charging Anub ' arak as due to his size this will result in a face pull prior to achieving charge range . It is possible to circle around the perimeter and attack from the rear or side so as to start the fight with him facing away from the remainder of the party . Spread out around the ring , tanking Anub ' arak in the centre . He will periodically stun the tank so do not be overzealous with DPS . Carrion Beetles will spawn when he is not submerged which can be easily killed with light aoe while the main focus of DPS remains on Anub ' arak . When not submerged he will cast Locust Swarm which results in a moderate damage aoe against all party members and pets ( usually cast shortly before submerge ) . When Anub ' arak submerges , all DPS should switch to the incoming adds which fall from above into the ring , with the main tank keeping an eye out for when Anub ' arak resurfaces in the centre of the ring . The area beneath a player about to be hit by Spikes is indicated by a shifting drift animation and can be easily avoided if the player moves quickly . So long as Anub ' arak is picked up quickly after each resurface and the adds are killed quickly , the boss fight should be easily controlled . If you find your healers running out of mana , an effective tactic is to prolong the submerged phase by killing all but the last guardian . While the tank and dps round up and deal with the other mobs , the healer sits back and does minimal healing , regenerating as much mana as possible . Once the healer is back to full mana , the last guardian is killed and the next phase begins . From experience it works best to only do this during the first two submerged phases , the third is usually too frantic and should be ended as fast as possible . Feral druids can really shine during this fight . Since they don ' t use mana for their attacks , a well played druid will be able to use Innervate on the healer , Rebirth on any party members who might die during the fight , heal the party with Tranquility and round out his job with Abolish Poison . And , because of the nature of the fight with the boss disappearing every now and then , even druid tanks will find some time to support their party with these spells . As this fight tends to be pretty intense , it ' s rare for a feral druid not to blow one or more of his cooldowns , and the lack of their use can point out a careless or badly played toon . Heroic Mode : Fighting Anub ' arak while he is up is easy , as long as the tank and melee can avoid Pound properly . The adds phase is the real challenge . Adds come in from all direction . Healers and DPS can aggro easily if the tank is not used to AoE tanking . Several tips here : Quotes . Intro : Aggro : Killing a player : Locust Swarm : Submerging : Death :
