Heigan the Unclean Heigan the Unclean is the second boss of the Plague Quarter in Naxxramas . 25 - man abilities . Phase two . After 90 seconds Heigan will teleport to the middle of the raised platform and begin channelling . 10 - man abilities . Heigan the Unclean has approximately 3 , 060 , 000 hit points . Note that unlike 40 - man Naxxramas the tunnel before Heigan is no longer a gauntlet . Phase two . After 90 seconds Heigan will teleport to the middle of the raised platform and begin channeling . Strategy . The fight goes as a 135 second cycle : Positioning and movement is everything in this fight . Heigan deals extremely low melee damage and has no enrage timer , which means no one should have to worry about getting off a last cast before moving . You won ' t have time . No matter how much time you think you have , it is likely not enough . During all of phase 2 , you will be almost constantly moving , and not worrying about casting anything or using any attacks . Tanks should not be afraid to turn their backs to Heigan , as his damage is low enough for a healer to easily heal through it . The only real source of damage ( if the raid can properly avoid Eruptions ) is Decrepit Fever , which should be removed immediately by a healer . Cleansing a disease is instant cast , and therefore can be done while moving . Alternate Strategy . For those groups that have trouble dancing , are heavy on melee dps , and which have a druid healer , there is an alternate strategy ( the " Lockard Maneuver " ) which can make this fight much easier . This approach hinges on the fact that Heigan ' s Spell Disruption ability only affects abilities with a cast time . Due to this fact , there is no need to dance at all in Phase 1 as long as your druid ( s ) ( and other healers ) can keep the tank up with HoTs and instant heals and you have sufficient melee dps to make good progress on the boss . To execute the strategy , simply tank Heigan on the platform during the entirety of Phase 1 . Make sure to tank him far enough on the platform that your melee dps won ' t be hanging off the edge , otherwise they ' ll take eruption hits . When he teleports to begin Phase 2 , quickly get off the platform to avoid the platform AoE and to prepare for the fast dance . Run the dance through to completion , and when he transitions back to Phase 1 , once again rush the platform to take him down . A well - geared group that is heavy on melee dps should be able to take him down in two platform phases , three at the outside . Although you will still be dancing in Phase 2 , the major advantage of this approach is that you don ' t need to worry about moving Heigan around during Phase 1 . The Phase 2 dance is faster , but you only have to concentrate on moving yourself , not trying to dps or position a boss as well . The Heigan Dance . Regardless of the strategy you use during this fight , the key to taking Heigan down is learning the dance . If you are able to do the dance , then the following strategy will optimize your DPS and make this fight go much faster , thus reducing the potential for wipes . Unless your group is mostly ranged casters , then the above alternate strategy would be best . However , if your tanks are doing about 10 % of group damage each , having your tanks run with Heigan doing nothing more than keeping aggro reduces the total group DPS output by about 20 % . The same will go for each melee class that is required to run , reducing your damage output for that party member by about 80 % , so something to consider when trying an alternate strategy that has your melee running with Heigan . You want to start the fight by having your tank rush Heigan on the platform and have all melee DPS go to the platform as well . It is a good idea to have him tanked as far back on the platform as possible so you avoid anyone on the platform from getting hit by the eruptions . This allows your tank and all melee to concentrate on doing the most damage to Heigan during Phase 1 . All of the healers and caster ranged classes should be out on the floor and working through the dance required for Phase 1 . The advantage here is that both ranged and healers can cast spells with worrying about the effects of Spell Disruption . With the tank stationary , they will also be able to manage the distance better individually rather than having to worry about the tank getting Heigan too close to the caster group . This provides more than sufficient time to cast spells for healing and DPS while allowing the tank and melee to maximize DPS . Note : Losing a healer during this stage has less impact than losing a tank out on the floor during eruptions . As Heigan approaches Phase 2 , there are 5 – 10 seconds between the last eruption and his teleportation and quickened eruptions , during which everyone must get to the starting zone for the Phase 2 dance . Begin running towards the starting zone just a few seconds prior to teleportation so you are not caught out on the floor during the first eruption in Phase 2 . Achievements .
