Loatheb Loatheb is the third and final boss of the Plague Quarter in Naxxramas . Commander Eligor Dawnbringer : " " Loatheb . The hideous result of fusing the living plague of the Plaguelands with the bog beast s of Azeroth , Loatheb is said to control the power of healing itself . " " 25 - man Abilities . Loatheb ' s melee is relatively weak . Loatheb has approximately 20 , 200 , 000 hit points . He will also enter a Berserker Rage at 12 minutes into the fight , killing anyone left alive . 10 - man Abilities . Loatheb ' s melee is relatively weak . Loatheb has approximately 6 , 690 , 000 hit points . 25 - man Strategy . This encounter is a DPS race that also hinges on making good use of the available time to heal . You will need one tank . It is important that everyone in the raid gains the Fungal Creep buff as soon as possible and keeps it . Only 5 people can get it at a time . Therefore each of your 5 groups should have an order to kill the randomly spawning spores , the highest DPS should get it first . As they spawn 5 people will move to the spore and kill it while stacked on top of it . The tank does not need or want the buff . Two healers should be enough to keep the tank topped off during the available healing time , the rest of the healers will need to heal the raid . Since Necrotic Aura only applies to healing done while it is active , there are a number of tricks available to healers to increase their window for healing , namely precasting a heal so that it casts just as the aura drops , and stacking up Lifebloom so that it will bloom when the aura drops ( full stack of 3 , ticking through the aura downtime also provides a decent heal ) . Priests can also use , as it does not actually heal , and so is not affected by the aura . However , Power Word Shield will not absorb Inevitable Doom damage and will absorb only part of the damage from Deathbloom , so it is best used on the main tank . Similarly , Sacred Shield on the Main Tank will help to reduce his incoming damage . It is important to note that heal over time spells and healthstones / healing potions will do nothing while the aura is up so only large heals should be used . An exception to this is the Holy Priest ' s Circle of Healing , which can be used at the end of the healing window , when there is no time remaining to use a spell with a cast time . When not getting the spore buff the raid should remain stacked to facilitate healing . Bandages during the 3 seconds and shadow protection potions can help ( these apply whether used within aura uptime or not , since they prevent damage instead of healing it ) . Should you divine shield or ice block Inevitable Doom the spore " debuff " will fall off and you will need to get it again . After a while , Inevitable Doom damage will become very difficult to heal so it is important that Loatheb is killed before this . The priest ' s discipline tree also has the talent Divine Aegis , which shields the target for 30 % after critical heals ( 3 / 3 ) . This effect has been reported to work also during the Necrotic aura ( still under investigation ) . 10 - man Strategy . Group construction : One group should be made of 4 DPS + 1 AOE - capable Healer . Any remaining DPS in the raid should be instructed to follow this group . The second group should have all tanks , remaining healers , and any extra DPS . Assignments : One member of the DPS should be assigned to locate , announce , and pop spores . All other DPS should focus solely on moving , and DPS . A second player should be assigned to announce pre - casting for healers . Positions : Loatheb should be tanked in the center of the room with healers positioned half - way between Loatheb and the entry door . The DPS group will be roaming . Spores : When a spore appears the assigned player should announce its location . All DPS in the raid should move within 10 yards of the spore , and then resume DPS on Loatheb . The assigned player then pops the spore . All DPS should focus on being in range of a spore , and hitting the boss - that ' s it . The assigned player should be the only member looking for spores and popping them . Healers : An assigned healer should announce " Precast ! " when there are 3 seconds left on the Necrotic Aura . All healers should then cast a 3 - second spell that will succeed the moment the healing window opens . Healers should then focus on their assigned targets using the fastest spells available . Healers with spells that heal over time ( HoT ) may be able to " load " spells onto members of the raid before the precast announcement . This will enable the HoT to tick during the healing window . Timed Lifebloom ' s with an expiration within the healing window may also help boost the healing . Notes Stacking method . The debuff given by the spores causes 100 % loss of threat from all attacks . Because of this , most raids are reluctant to allow the debuff to reach the tank . Use the Divided Method for the first two spores that enter the room . This allows the raid to sustain their DPS with the increased crit chance , but also completely diminishes their threat . During the first two spores , the tank focuses solely on raising his threat on Loatheb as high as possible ( tanks doing 4k + TPS have no problem reaching insurmountable amounts of threat within the first two spores ) . Positioning of Loatheb and healing assignments are the same as found above . Once the third spore enters the room , all players in the raid stack on the tank , and no one chases after spores from this point on . The spores are then allowed to crawl their way to where the entire raid is standing , and the spore is popped giving the entire raid the increased critical chance and 100 % loss of threat debuff . At this point , there is no downtime from DPS having to run around the room , and all raid members , including the tank , begin to crit non - stop . Because everyone in the raid has 100 % loss of threat , there is no need to worry about the tank losing threat ( unless someone taunts Loatheb , which should be avoided at all cost ) . Loatheb can be demolished with this strategy by roughly doom # 10 , # 15 maximum . Classes . Affliction Warlocks . An affliction - spec ' d warlock with the 51 - pointer Haunt will be able to save the raid healers some effort . Watch the debuff that prevents healing and when it ticks from 13 to 12 seconds remaining , start casting your Haunt . This will increase your DPS as Haunt always does , but it also means that the healing effect will return to you with 1500 - 2000 health during the three seconds when healing can take place . Death Knights . All Death Knight ' s have an attack called Death Strike - if timed properly and with 2 sets of [ death , frost , unholy ] runes you can heal yourself for 3500 - 5000 total with 2 strikes . Death Knights may also summon a ghoul and then immediately use Death Pact to restore another portion of their health . Death Knights may also use Anti - Magic Shell , Icebound Fortitude and / or Unbreakable Armor during Dooms to help reduce the amount of incoming damage . The last two only being available for those in frost specc , or Lichborne in partial Frost specc additionally the last two will not reduce the actual Inevitable Doom damage but instead mitigate all other incoming damage . Paladin Tanks . A Paladin tank may heal him / herself towards the end of the combat , any support - healing in this part is a plus . In addition , if the raid is having trouble healing , the paladin should consider using Seal of Light , instead of a typical tanking Seal . Since dps with the Fungal Creep debuff will not generate any threat , maintaining a tanking Seal for threat generation should be unnecessary . The additional healing from Seal of Light during the 3 seconds that Necrotic Aura is not up may help slightly to reduce the load on healers . Notably , though , some Paladin tanks will continue to prefer using a tanking Seal , if only to generate additional dps to expedite the end of the fight . Paladins ( preferably retribution paladins should your raid have them , as Judgement of Light scales excellently with AP ) should also be certain to maintain Judgement of Light , to further enhance overall healing on the raid during the 3 seconds that Necrotic Aura is not up . Paladin tanks should maximize their stamina and block value ( and block rating , if not already block - capped ) during this fight , rather than avoidance . Loatheb ' s melee strikes are so modest that the majority of his melee damage can be entirely mitigated simply through blocking . Trivia . The word " Loatheb " is an anagram for " Healbot " , and considering his abilities , this is likely an intentional joke by the developers . Videos . Solo encounter .
