Herald Volazj Herald Volazj , a faceless one , is the last boss of . He is located within the Fallen Temple of Ahn ' kahet . He is a herald of Yogg - Saron and enemy of the nerubians . Strategy . It is highly recommended to warrior tanks to Spell Reflection the Mind Flay . Insanity Before Volazj completes its casting , all group members should remove their weapons . This will significantly lower the damage taken during Insanity . Don ' t forget to re - equip them . Damage classes face a race to kill their clones quickly so as to aid other members . The kill order should be to first down the healer clone in your party , the damage clones , followed by the tank clone last . Classes with AoE can down all of the clones when they are grouped together . Party clones will not use trinkets or your special abilities . Once out of your Insanity phase , you can assist others . If there is a Death Knight in the group , he will always death grip you to him , so be prepared . Healers and tanks can and should use whatever means necessary to focus on survival while waiting for your party members to dispatch your evil counterparts and end Insanity . It is possible to finish off your own group in some situations with abilities like Holy Nova or Spell Reflection , but your focus should be to stay alive . A priest used to be able to Mind Control and cancel it and it would kill the clones immediately . This little glitch was fixed . A reasonably geared Holy paladin healer can also handle Insanity with ease . With the high armor , he can AoE tank all the clones and heal himself with Holy Shock . By spamming Consecration , Judgement , Shield of Righteousness , and occasionally Holy Shock , the clones will be finished quickly . It should not be necessary for druid s to change form in preparation for Insanity . For instance , a restoration druid switching from tree of life to dire bear just before the phasing , hoping to make the fight easier . They may find a very difficult to kill resto bear charging and healing their group members even without having the appropriate talent . An alternative strategy is to de - equip a DPS and send him / her to their death before the tank begins tanking . With one less person in the fight , Insanity becomes much , much easier . The fight is still very manageable with 2 DPS sacrificed as Volazj does not have much health . Group makeup can greatly change the dynamics of the fight . Having almost all ranged DPS classes can add difficulty to the encounter . If you find difficulty as a melee trying to get to the ranged , the pillars along the walls can aid in line of sight gathering the ranged . Keep in mind , the " clones " can and probably will walk through the pillars to get to you . Heroic . Follow the same strategy as normal . When the boss is casting Insanity have everyone quickly unequip their weapon to make the fight easier . If done correctly the damage of the clones will be much lower . Similarly , hunters can switch to Aspect of the Viper to lower the clone ' s damage . Make sure you equip your weapons again after Insanity finishes casting or you will be there for a very long time . Sometimes it may be better to try with fewer people . The abilities of each clone are based on each characters ' spec . This means a hybrid class that has not spec ' d for healing will not heal ( such as a feral druid ) . However , a resto druid will still heal even if they shift into bear or cat form before the Insanity cast finished . Use silence / stun on the healer clone to interrupt him and kill him first . Macro to unequip weapons ( needs 3 slots empty in rightmost backpack ) : Achievement . Volazj ' s quick demise is easiest with a protection warrior tanking the boss . Volazj ' s mind flay can be Spell Reflected for considerable damage . It is possible to complete the achievement just by nuking the boss and killing the illusions made from the two insanities as quickly as possible . Other tactics include heavy nuke on the boss when he casts the first insanity , bringing him from 66 % to 33 % before he finishes the cast , he will then start to cast the second insanity and needs to be killed before he finishes the cast or the party will be faced with 10 copies per person ( instead of 5 ) . Another viable tactic is to have the healer suicide ( preferably just after the first insanity ) . This will make the second insanity much easier due to having 9 copies less to deal with , however this tactic does require a well geared warrior tank and probably the use of health pots . If a Death Knight summons Army of the Dead during the insanity cast , the army will not phase with the players and instead will continue to attack Volazj , shortening the fight and the time between insanity phases . Additionally , if Volazj is killed before he completes casting insanity , or if he dies during insanity from dots or other damage , he may bug . No loot icon will appear when mousing over his corpse , but he may still be looted by right - clicking . Additionally players will be stuck in their different phases and will not be able to see each other , or possibly the boss . This can be remedied by players either leaving the instance , or logging out , one at a time . After each player loads back in , they will be able to see all of the other players who have done so . Notes . Herald Volazj speaks a language unpronounceable , let alone comprehensible , to any race other than the faceless ones . However , players also receive whispers in their mind when he speaks , translating what Volazj " says " . His language can be deciphered as :
