Prince Malchezaar Prince Malchezaar is a raid boss located at the very top of Karazhan . Background . Little is known about him , except that he is a man ' ari eredar , he claims to be a prince , and that he is a member of the Burning Legion . It is unknown how or when he arrived at Karazhan or what his purpose there is . He apparently arrived while some agents of the Violet Eye were still alive inside Karazhan , notably Keanna . It was likely shortly before Karazhan was sealed , as the Violet Eye were aware of Keanna ' s death . From his loot , we can learn more about him and what he did before coming to Karazhan . He has the Sunfury Bow of the Phoenix , which could indicate that he has been in contact with the blood elves . Possibly , he sealed the alliance between Kil ' jaeden and Kael ' thas Sunstrider . He has also obtained Grom Hellscream ' s axe Gorehowl . It ' s possible that he went to Ashenvale and invocated the Demon in Demon Fall Canyon . If he has the Book of Medivh , the Burning Legion has a plan for him , invocating something ( possibly Nightbane ( boss ) as the players ) or for a future use . Anyway , he had to maintain the power and the influence of the Burning Legion in Karazhan . Due to his death giving the player the Karazhan achievement , he is now considered to be the tower ' s final boss . However , some used to consider the creature Nightbane to be the true final boss of Karazhan due to his superior difficulty in the early days of the dungeon ' s release . Their comparative difficulty is now disputed . In any case , Prince Malchezaar is a difficult boss for raids when they first reach him . Beating him requires good gear on everyone : The tank , the dps , and the healers . It also requires skilled execution by all players . Prince Malchezaar can be encountered after the Chess event and controls all of the trash between the Game Room and Netherspace . Strategy . The fight with Prince Malchezaar has three phases : Phase One . Phase One starts immediately when Malchezaar aggroes . The door to the balcony closes , and Malchezaar starts summoning infernals and casting Enfeeble and Shadow Nova . He casts Shadow Word : Pain on the tank . Phase Two . Phase Two starts when Prince Malchezaar is reduced to 60 % health . He warps in axes , which substantially increases his melee damage . He stops casting Shadow Word : Pain and starts Parrying and Thrashing and casting Sunder Armor on the tank . Infernal summoning , Enfeeble , and Shadow Nova continue as in Phase One . Thrash is the biggest threat during this phase and can deal more than 12 , 000 damage inside of a second . Healers should keep the tank as close to full health as possible and stagger movements during group shifts to ensure the tank does not go very long without a heal . Phase Three . Phase Three begins when Prince Malchezaar reaches 30 % health . Melee damage on the tank returns to Phase One levels . He stops using Enfeeble , Thrash , Sunder Armor , and Parry . He continues casting Shadow Nova . He starts casting Shadow Word : Pain and Amplify Damage on random raid members . He throws his axes into the air where they fly around attacking raid members at random . He starts summoning infernals much more frequently . Safe Spots . While the safe spots were removed in patch 2 . 4 , raid groups were formerly able to use several pairs of small areas where infernals would never land . This was never confirmed officially as an exploit , but was still removed . Infernal Spotting . Malchezaar emotes either " You face not Malchezaar alone , but the legions I command ! " or " All realities , all dimensions are open to me ! " immediately before summoning an infernal . If you look to the sky beyond the balcony , you ' ll see a bright yellow meteor headed toward the raid . Its trajectory is a little tricky but somewhat predictable . One responsible non - melee raider should act as a spotter . He receives a raid marker and has three jobs : The other ranged raiders stick close to the spotter . It ' s possible to skip the raid marker and announce safe spots , but using the marker requires a lot less communication . As for the infernals themselves : before landing , they fly in a straight line toward a point in the arena , but shift direction suddenly at the last second , usually down . Naturally , your spotter should be smart about choosing a safe spot . A wide open place is better than sandwiched between two infernals ' AoE , and the area of the Prince ' s Shadow Nova is right out . During Phase Three , Malchezaar summons infernals at an increased rate , so watch those emotes . Wipes . Wipes on Prince Malchezaar are typically caused by one of four things : An infernal landing in a bad spot right as an Enfeeble hits . To deal with this , simply watch for infernals , and make sure that there is always room to run . Otherwise , try again and hope for luckier infernal positions . A lack of heals on the tank when the healers change positions to avoid an infernal . Healers must have a plan to ensure that the tank never goes without heals during a move . This may require that a healer briefly take damage from an infernal . In Phase Two , a huge damage spike on a warrior tank caused when rapid - fire Thrash attacks use up Shield Block charges and lead to crushing blows . This is even worse if Malchezaar Parries at the same time . These spikes are not avoidable . The healers and the tank must simply use their normal techniques to ensure survival in the face of this damage . In particular , healers must continuously cast big heals in Phase Two " even if the tank is at full health . " By the time the heal lands , he won ' t be at full health any more . Parries can be reduced or eliminated by Expertise on the tank and by melee damage - dealers hitting Malchezaar from behind . Running out of room in Phase Three due to too many infernals spawning . The solution to this is to increase damage output so that the Prince dies before this happens . Note that better gear , especially on the damage - dealers , reduces the possibility of all of these problems . Quotes . Aggro : Summoning an Infernal : Starting Phase Two : Starting Phase Three : Killing a player : Death : Bugs . Prince Malchezaar sometimes casts Enfeeble on the tank at the very start of Phase Two . Reports are mixed on whether this bug is threat - related or not . Another bug is when his knock back instantly kills a player caught in it . External links .
