Patchwerk Patchwerk is the first boss of the Construct Quarter in Naxxramas . He is typically seen as a gear check , and is a prime example of a tank and spank fight . Abilities . Patchwerk ' s abilities are the same for both 10 - player and 25 - player raids , but his health and damage are scaled accordingly . These two scaled values will be shown together below , separated by a slash . Melee . Strikes a single target for ~ 9 , 000 / ~ 18 , 000 physical damage . Hateful Strike . A rapid and powerful melee strike on a single target / two targets for 20 , 000 - 27 , 000 / ~ 80 , 000 physical damage . Cast every second . Hateful Strike also adds threat to the three players who have the highest threat . The target of Hateful Strike is determined by three requirements : Each requirement is dependent on the ones before it , so a high - threat player isn ' t considered if she ' s out of range . Similarly , a high - health player isn ' t considered if he ' s low on threat . Frenzy . When Patchwerk ' s health reaches 5 % , he will gain 25 % increased damage and 40 % increased melee haste . This buff also applies to the damage caused by Hateful Strike . Berserk . After 6 minutes of combat , Patchwerk will enrage . His damage is increased by 500 % , his attack and movement speed is increased by 150 % , and he becomes immune to taunt effects . While enraged , Patchwerk will also cast Slime Bolts at all raid members . These hit for ~ 9 , 000 Nature damage , followed by ~ 6 , 000 damage every 3 seconds for 6 seconds . Strategy . Defeating Patchwerk depends on sustaining heavy DPS and managing Hateful Strikes . Without sufficient damage , Patchwerk ' s enrage will eventually destroy the raid . Without dealing with Hatefuls , Patchwerk will rapidly kill the raid ' s melee ; losing these members will likely put the rest of the raid in an impossible situation . However , dealing with these two concerns will make Patchwerk an easy fight . Hateful Strikes . Off - tanks are the safest approach to Patchwerk ' s Hateful Strikes . These tanks will have enough health and generate enough threat to shield the less armored melee from Patchwerk ' s attack . Since Hateful Strikes are physical damage , the off - tanks ' avoidance and armor will reduce the actual damage taken . This also simplifies the task of healers , as Hateful Strike targets will be very predictable . Note that in 25 player mode , two off - tanks will be needed to fully protect the melee members . If necessary or convenient , raids may substitute a DPS member in place of a dedicated off - tank . If low DPS is a problem , this compromise of security for damage may be prudent . Assuming you have 2 tanks , it is advised to let your " best " tank ( the one with most health and armor — dodge is useful ) be the Hateful tank , and have your lesser geared tank take Patchwerk ' s normal hits . Enrage Timer . Patchwerk ' s will enrage after six minutes of combat . This enrage is not survivable , so raid DPS must be sufficient to kill Patchwerk before six minutes is up . For 10 player , the total raid DPS must be at least : formula _ 1 , which requires each DPS to be at least : formula _ 2 For 25 player , the total raid DPS must be at least : formula _ 3 , which requires each DPS to be at least : formula _ 4 In summary , ~ 2 , 000 DPS per DPS is necessary to defeat Patchwerk . These requirements will be slightly lower in practice since tanks will contribute DPS as well . Pulling . Patchwerk is linked to the other enemies in his hallway , so these enemies will need to be cleared before Patchwerk is engaged . Once the room is clear , Patchwerk may be pulled . Engaging Patchwerk should be done deliberately to ensure that Hateful Strikes don ' t target unsuspecting raid members . The main tank and off - tanks should engage first , ahead of the melee DPS . Off - tanks should follow the main tank in as closely as possible to prevent the main tank from suffering Hateful Strikes . However , the off - tanks may stand behind Patchwerk ; they do not need to stack on top of the main tank . Once these members are in place , all melee DPS may safely engage Patchwerk . Healers and tanks should be aware of the fickleness of this pull : until the tanks are in position , Hateful Strikes may hit unexpectedly . Healers should be prepared for this burst damage , and tanks should be prepared to use cooldowns to prevent their death . Frenzy . Frenzy is a brief , but significant , increase of Patchwerk ' s damage . A raid with the minimum DPS necessary to kill Patchwerk will endure Frenzy for about 18 seconds . Emergency cooldowns , such as Shield Wall or Survival Instincts , should be used to offset this buff . These cooldowns should cover the almost all of Frenzy , but if the raid has dead or OOM members , healers must be ready to offset this damage for a longer period . Trivia . His name comes from the term " patchwork " ; as an abomination , he is a disgusting amalgamation of flesh , bones , meat , metal , and threads . It may also refer to Kraftwerk , a German minimalist techno group , just as Ramstein refers to the similarly named German band . The Avatar of War refers to the Everquest boss of the same name . The boss had a similar ability to Hateful Strike in that it would unleash massive damage to the tank which would have to be healed through . It was widely believed at the time that no player could possibly tank that . Quotes . Commander Eligor Dawnbringer : " " Behold , Patchwerk . When word of his existence first reached the ears of the Brotherhood , none believed the tales of an abomination with such immense speed and strength . Fewer still believed it when he fell the first time . . . " " Acherus : The Ebon Hold . " Note : All Ebon Hold quotes are voiced too . . . " External links .
