Harbinger Skyriss Harbinger Skyriss is one of the qiraji entities that the naaru kept locked up within the Arcatraz . He is a servant of the Old Gods and seeks to usher in his masters ' vision of conquering all of the worlds in the universe . His plans were surprisingly rewarded when he was picked up by the naaru . He must have corrupted into releasing all the prisoners in the Arcatraz . Skyriss uses the same model as , and appears as the 4th and final mob of a multi wave encounter in The Arcatraz wing of Tempest Keep . The encounter is begun by engaging . The warden will in turn open the four orbs along the walls of the room , and finally wake up Skyriss . There are two different varieties of each mini - boss . If the mini - bosses are killed quick enough , there ' s time for regeneration out of combat between them . The encounter can be reset by running out , after a certain wait time Mellichar will respawn , just like after a wipe . Many of the mini - bosses , as well as Skyriss himself , are based on classic " World of Warcraft " raid bosses . " Note : The encounter is not able to be reset if you wipe after Harbinger Skyriss appears but before he becomes attackable ( this can happen if a party wipes on the final orb mini - boss ) . An instance reset is required to reset the encounter if this occurs . " First Orb . At first , either a Blazing Trickster or a Warp Stalker will spawn . Blazing Trickster . A level 70 , elite imp which will shoot Firebolt s at random party members and occasionally use Weakened Soul debuff . The damage isn ' t great and he doesn ' t have a lot of HP so should be nuked down fairly quickly . Phase - Hunter . Also fairly simple , except he has a blink move that randomly moves him across the map , so the tank has to be on his toes about grabbing aggro back , especially if the Warp Stalker gets to a healer . Use good hate control techniques ( waiting for tank to put on several Sunders before beginning DPS ) and this fight should be over quick . Second Orb . The second orb does not contain a monster , but rather a helpful NPC ( , a mage type ) . Millhouse is a great help . When he ' s released , he will drink and buff himself , and then join the fight . He deals substantial DPS . Third Orb . This spawns either Sulfuron Magma - Thrower , or Akkiris Lightning - Walker . Akkiris Lightning - Waker . Clear the curses , dispel the buff on the mob , and this boss is a pushover . Elemental Shamans in the group should move to assist the healer . Fourth Orb . The last mob before the boss is a Twilight or a Blackwing Drakonaar . Blackwing Drakonaar . Only the tank should be taking damage from the blastwave , as all other melee DPSers should wait until the first blastwave before engaging and then disengage after 15 seconds or so until the next one . Ranged damage dealers should stay at max range to avoid it . Unless you have a very high DPS group that can burn him down quickly , you will not be able to kill him before Harbinger Skyriss appears . BUG WARNING : If your MT tries to tank Blackwing Drakonaar up against either side wall of the room , there ' s a chance that the boss will EVADE bug when the tank is knocked into the air from a Blastwave knockback , causing Blackwing to regain health ~ 48 % instantly . This is caused due to the small ledge about half way up the wall that the tank may land on during his fall . Twilight Drakonaar . This mini - boss does a form of time lapse that incapacitates the tank for a few seconds . He has fair magic resistance to all schools . He also does random brood powers similar to those of the drakonids in Blackwing Lair : Strategy . Skyriss behaves much like from the Temple of Ahn ' Qiraj . The clones have less hitpoints and a somewhat reduced set of abilities . They have a normal non - stunning Mind Flay which deals less damage than the original , however if Skyriss and the clone both use their flay / rend on the same person that person will most likely die . Healing is the key to this fight . Secondary healers should wear their best healer outfit . The job of the backup healer is to keep Millhouse alive , and to make sure the main healer survives when he ' s affected by the mind flay . How to deal with Skyriss ' abilities : 1 . Skyriss clones 2 . Random Target Mind Rend 3 . Mind Control Shadow Protection buff is helpful to resist or break the MC early as well as the mindflay . A warlocks Felhunter pet can use " Devour Magic " on fears / mind rends / mind control debuffs . Mages can blink or ice block out of the mind flay , minimizing the damage they take . A Rogue in melee range will attract every fear and many mind controls ; conscientious rogues will equip their PvP trinket and use it early in the fight to absorb as much CC as they can . Bear in mind that Cloak of Shadows can be used by Skyriss while you are Mind Controlled , and break the effect early . Hunters - make sure to get a Snake Trap out , Skyriss will Mind Flay the snakes , saving you a few Mind Flays and making it easier on your healer . Quotes . When released : Killing : Fear : Mind Control : Clones : Killing a player : Death : Trivia . Skyriss is the only qiraji prophet caste member that does not spawn within Ahn ' Qiraj .
