Four Horsemen The Four Horsemen are the third and final boss encounter in the Military Quarter in Naxxramas . Summary . At the beginning of the fight , each of the four horsemen will run into different corners of the room , the two melee horsemen closest to the entrance , the two ranged at the back . Each horseman will periodically Mark anybody within 45 feet with a debuff that causes more damage each time it stacks . If nobody is in range , the horseman will AOE the room and the raid will wipe . Most strategies involve keeping all four horsemen occupied , while moving tanks and DPS between the bosses so that no player stacks more than three marks from any one horseman . 25 - man Abilities . The Four Horsemen each have approximately 2 , 370 , 000 hit points . They will run into separate corners of the room when engaged . Thane Korth ' azz . A former dwarven king turned Death Knight . Melee fighter . He will run into the near left corner of the room when engaged . Baron Rivendare . A male human Death Knight , recently Scourge overlord of Stratholme . Melee fighter . He will run into the near right corner of the room when engaged . Lady Blaumeux . A female human Death Knight . Ranged combatant . She will run into the far left corner of the room when engaged . Sir Zeliek . A Paladin who resisted turning into a Death Knight . Ranged Combatant . He will run into the far right corner of the room when engaged . Note : Thane Korth ' azz and Baron Rivendare will both cast their marks in unison , while Lady Blaumeux and Sir Zeliek will both cast their marks in unison . Because of Lady Blaumeux and Sir Zeliek ' s lower casting frequency , it is completely possible for their Mark debuffs to wear off and reset the stack counter . After 100 marks have been cast the Horsemen will berserker enrage increasing all damage done by 1 , 000 % . The encounter ends when all Four Horsemen have been slain . 10 - man Abilities . The Four Horsemen each have approximately 781 , 000 hit points . They will run into separate corners of the room when engaged . Marks will reduce threat by 50 % Thane Korth ' azz . A former dwarven king turned Death Knight . Melee fighter . He will run into the near left corner of the room when engaged . Baron Rivendare . A male human Death Knight . Melee fighter . He will run into the near right corner of the room when engaged . He does not cleave , nor does he have a shadow damage aura besides marks , contrary to some rumours . Lady Blaumeux . A female human Death Knight . Ranged combatant . She will run into the far left corner of the room when engaged . Sir Zeliek . A former paladin turned Death Knight . Ranged Combatant . He will run into the far right corner of the room when engaged . 25 - man Strategy . This encounter is a lot simpler than it seems . You will need two tanks . The Horsemen will automatically run to their corners , the raid will split into four groups one for each Horseman . The Zeliek and Blaumeux healers can remain in the middle without taking mark stacks and heal their ' tanks ' . Depending on what you find more difficult to heal you can switch the healers around but unless you are bringing 8 healers some groups will have to be covered by one healer . Each group will run to their Horseman . The Korth ' azz and Rivendare groups should stack up on their tank . The Zeliek and Blaumeux groups should be at max range in between Zeliek and Blaumeux . Every three marks the Korth ' azz and Rivendare groups will switch places and the Zeliek and Blaumeux groups will switch places . The Korth ' azz and Rivendare tanks should drag their Horseman to near the door where you enter and taunt off each other , then drag their new Horseman back to their corner . Because of Meteor both groups will need to remain stacked on their tank . Another alternate more dps - efficient strategy is to wait for three marks and a meteor before switching , eliminating the need for the dps and healers on the melee bosses to move at all . The Zeliek and Blaumeux ranged tanks should start running for each other ' s position as soon as the third mark goes off . After Korth ' azz and Rivendare are dead their groups will switch to Zeliek and Blaumeux , remember to stay spread out on Zeliek and be careful of Void Zones on Blaumeux . You will still need to switch sides every 3 marks . Keep in mind they will target the closest player to them with their nukes . All the tanks except Korth ' azz ' s will take a lot of damage in this encounter , be prepared . 10 - man Strategy . The encounter is like the 25man . You will need two tanks . The Horsemen will automatically run to their corners , the raid will split into three groups . Each group will run to their Horseman . The Korth ' azz group should stack up on their tank . With Baron Rivendare ranged and the healer can easily outrange his aura to ease the stress on healers . Every three marks the Korth ' azz and Rivendare tanks will switch Horsemen and the healer and ranged dps tanking Zeliek and Blaumeux will switch places . The Korth ' azz and Rivendare tanks should drag their Horseman to near the door where you enter and taunt off each other , then drag their new Horseman back to their corner . Because of Meteor both groups will need to stack on their tank during the swap . Another alternate more dps - efficient strategy is to wait for three marks and a meteor before switching , eliminating the need for the dps and healers on the melee bosses to move at all . The Zeliek and Blaumeux tanks should start running for each other ' s position as soon as the third mark goes off . After Korth ' azz and Rivendare are dead their groups will switch to Zeliek and Blaumeux , remember to stay spread out on Zeliek and be careful of Void Zones on Blaumeux . You will still need to switch sides every 3 marks . Keep in mind they will target the closest player to them with their nukes . Their nuke is however really weak and can be dealt with easily with any healer class . In 10 - man only the group tanking Korth ' azz will be taking heavy damage . Easy 10 - man Strategy . Need : 2 tanks , 3 healers ( tested with 3 , probably 2 possible too ) , at least 1 caster dps , preferably with self - healing abilities . Why / when to use : when your party dies from taking too much mark damage . This tactic will put fewer marks on the DPS ( @ switch from 3 to 3 - and - 1 instead of from 3 to 4 - and - 1 ) and migrate damage a bit more to the tanks ( meteor , marks ) instead of party , so in most cases it will become easier to heal . How it works : All 4 horsemen will run to a corner , where they need to be tanked . The key in this fight is that you need to switch tanking targets after each few marks , or the stacking damage from the marks gets too big . You need to split up raid into groups , and let them stick in a corner . When the encounter starts , all groups start getting aggro on the bosses in their corner . BLUE group goes all out on Korth ' azz , with skills , cooldowns , etc . He needs to be down fast because of the meteor . RED group will tank Rivendare and stay alive . YELLOW tanks the ranged boss in the west corner and heals itself and the green ranged tank . GREEN tanks its ranged boss . Now comes the switch . At the moment the 3rd mark hits , YELLOW and GREEN need to switch . They do this simply by running to the others position , because the boss will target the closest person . Now they start to tank the other boss and stack 3 other marks . Switch again after 3 . After the 3rd mark hits , the RED and BLUE tank move towards each other , so they can switch targets with taunt , before mark 4 . Then move back to your old corner . Start DPS / tanking / healing again . Switch every other 3 marks . Repeat till Kor is dead , then move to Riv , followed by Blau , then Zel . Congrats ! NOTES CLASS NOTES Remember to coordinate with the other tank , move to each other after mark 3 , taunt quickly , move back fast . Don ' t forget that marks lower threat by 50 % . Yellow heal yourself and green . Red heal yourself and red tank . Blue heal yourself and blue tank and DPS ( AoE heals ) . Nuke Korth ' azz , save skills and CDs for Rivendare . Don ’ t walk along with the tanks or you may get an extra mark . Zerg Strategy . It helps to have a shaman in group for Bloodlust / Heroism , as well as the raid having high DPS output . The setup is exactly the same as above , except instead of splitting the DPS between Korth ' azz and Rivendare , all of the DPS group up with the tank for Korth ' azz . It also helps for both range tanks to be able to heal themselves , so that the maximum number of DPS can be on Korth ' azz . As soon as the encounter begins , all CD ' s and heroism are popped to take Korth ' azz down as fast as possible . Having a good AoE healer in group helps , as you will more than likely get close to 5 marks of his debuff . If you are having problems with one of the healers dying during this process , you can have only the healers switch in between meteor casts at about 2 or 3 stacks of the debuff . As soon as Korth ' azz is down , the DPS / Healer / Tank who were on him run over to Rivendare ' s corner and engage him , while the other tank ( and healer if he has marks ) move to Korth ' azz ' s corner to remove marks . DPS and healers can stay at max range on Rivendare to avoid marks , or just step out of range at 3 - 4 ticks until marks are removed . The only rotation of players needed is for the tanks ( and possibly healers ) to switch when 3 - 4 marks are reached until Rivendare is down . If the debuff becomes a problem for DPS ( too many are dying ) , the DPS can just follow the tank to Korth ' azz ' s corner until the marks are removed . Once Rivendare is down , the DPS helps finish off Zeliek and Blaumeux , again staying at max range or rotating to avoid marks . Distracting Shot Strategy . Another possible alternative to this encounter is for a hunter to use Distracting Shot on their tank ' s new target , then allow their tank to taunt off of them . Obviously this strategy only works when there is one or more hunter in the group . Beacon of Light 2 - Healer Strategy . A slight variation to the 10 - man strategy above is using a Holy Paladin to heal the front and another healer for the back . With the change to Beacon of Light in 3 . 2 ( i . e . 60 yard range and over - healing being applied to the Beacon target ) , it is possible to cast Beacon on the single tank in the front and heal the rest of the group normally . Whenever the tanks swap , also swap the Beacon target . When using this approach , be sure to carefully calibrate the range between the two groups , as the single tank can get out of range easily . A range - displaying addon may prove helpful when using this approach . Horsemen conversation . When players pass beyond Gothik the Harvester , the Four Horsemen have a sort of conversation during which they are all introduced . Inspiration . They were originally based on the from the , said to bring the end of the world — Sir Zeliek as the White Rider of Conquest , Thane Korth ' azz as the Red Rider of War , Lady Blaumeux as the Black Rider of Famine , and Baron Rivendare / Lord Mograine as the Pale Rider of Death .
