Kologarn Kologarn is the sixth boss encounter in Ulduar released in patch 3 . 1 . 0 . He guards the Shattered Walkway into central Ulduar where not only is he protecting the bridge , he is the bridge . Players fight not only him but two detachable arms that appear to be separate mobs that can be " broken " off of him . Background . Loken requisitioned Ignis the Furnace Master to create this towering giant as a guard to the Shattered Walkway . His oversized proportions allow Kologarn to easily crush any intruders who attempt to reach the inner sanctum . Strategy . The fight with Kologarn is a battle for survival , not a DPS race . The stuns , Eyebeams , tank debuffs , and massive AoE damage all conspire to gradually pick off raid members until the raid cannot keep itself alive . That said , high DPS on the Right Arm is useful to ensure that it does not cast Stone Grip more than once before it is destroyed , and that it quickly drops its victims when it does cast Stone Grip . Composition and assignments . As a battle for survival , beginning 25 - man raids can bring four tanks and eight healers . At least three healers should be priests or shamans , capable of group heals to recover from AoE damage . Assign two or three healers to care for the tanks and two healers to keep the victims of Stone Grip alive . In 25 - man raids , at least half of the damage - dealers should be capable of ranged AoE effects . The healing and tanking requirements of the 10 - man fight are considerably less severe than the 25 - man , but three or four healers and two tanks are best . Positioning . Kologarn remains completely stationary in this encounter at all times . He cannot be turned or range tanked . If his aggro target is not in melee range , he casts Petrifying Breath on the raid , which causes a wipe . His arms do not need to be offtanked , but can be separately targeted and hit within Kologarn ' s hitbox . Since their hitbox overlaps with Kologarn ' s , melee attackers should face his torso , not the arm itself . Melee , position under the Left Arm ( on the right side ) for 25 - man . Any position is OK for 10 - man . Face the torso . In 25 - man , two or three tanks on the torso , position front and center . Only one is required for 10 - man . One Rubble tank , position under the Right Arm ( on the left side ) . Ranged damage - dealers and healers , position in a line across the middle of the room . Stay out of melee range to avoid spell interrupts . Make sure that there is room to the back wall , and there is nobody directly behind you . The fight . For 25 - man , two to three tanks establish a taunt rotation on Kologarn . Every 10 – 15 seconds , he casts " Overhead Smash " . This applies Crunch Armor , which reduces the tank ' s armor by 25 % per stack and lasts 45 seconds . Once it gets to two stacks , a tank without the debuff taunts the boss and takes over . Keeping all tanks alive is vital in order to rotate the debuffs . For 10 - man , Crunch Armor expires quickly , so no taunt rotation and only one tank is required on the boss . All damage - dealers , attack the Right Arm until it is destroyed . Destroying it damages the torso , and eventually kills the boss . Killing an arm spawns a pack of Rubble earth elementals , which are picked up by a tank and killed immediately . In 25 - man mode , the Rubble elementals have a point - blank AoE damage spell called Stone Nova which quickly kills any nearby characters that are not tanks . Keep away from the the Rubble and kill them with ranged AoE effects while melee attackers hit the body or the Left Arm . In 10 - man mode , the Rubble can be dragged to the center and hit by melee attackers . Once all the Rubble are dead , attack either the Left Arm or the body , depending on the strategy . The Right Arm respawns 60 seconds after it is destroyed . When it respawns , all damage - dealers attack it again . Killing an arm four times generally does enough damage to kill the boss . Raids may wish to kill the Right Arm four times , or kill the Right Arm three times , then kill the Left Arm once . Kolgogarn regularly casts his Focused Eyebeams at a random member of the raid , generally preferring a character who is not at close melee range . The Eyebeams slowly follow the target , kicking up stone chips and inflicting massive damage on any character they touch . Targets of the Eye Beams should run to the back of the room , then out the door and down the stairs , until Kologarn stops casting the Eyebeams . Anyone in this path must get out of the way . Notes . The hole that holds Kologarn is in fact a hole . Do not fall in . The hit box for the boss and his arms is huge and shared . Melee can hit an arm from nearly the opposite side of the room . AoE attacks that hit one of the three targets always hit and damage all three of them . Therefore , abilities like Multishot and Divine Storm are very useful for inflicting extra damage on the boss . Healers caught in Stone Grip or running from Eyebeams cannot heal . They should call out to let the other healers know who will need extra healing . Stone Grip , Eyebeams , and Shockwave can all kill raid members quickly . Keep everyone a full health at all times . If you are having trouble keeping everyone topped off , bring in more group healers . Kologarn is typically the fourth boss faced in Ulduar ( after Flame Leviathan , XT - 002 Deconstructor , and Razorscale ) . He outputs much more damage than any other raid boss seen before him . Healers may be in for a nasty shock , as they must work harder than they ever have before . Overhead Smash can miss or be dodged or parried to avoid an application of Crunch Armor . This delays the time at which the next tank must take over and may allow Crunch Armor to expire . Therefore , avoidance gear is preferred over stamina gear on this boss . Do not use AoE taunts on the Rubble elementals if you are not in melee range of the boss . Taunting the boss while out of melee range results in him casting Petrifying Breath on the raid . The Right Arm is the primary target because Stone Grip , while it does less damage , is more dangerous than Shockwave . Stone Grip , in 25 - man fights , can randomly stun multiple healers , leading to deaths and eventually a wipe . Also , continually attacking the Right Arm causes it to release Stone Grip victims much more quickly . Shockwave , while nasty , is at least predictable and can be managed with group heals . Inexperienced raids tend to wipe due to Eyebeams . Avoiding them is everyone ' s highest priority , period . If the Eyebeams target you , run directly out the door . Do not dodge other players . It is their responsibility to get out of your way , and there should be nobody in the doorway anyway . If you see Eyebeams on someone else , make sure that you are not standing between them and the door . Hunters and Shamans can and should put up Aspect of the Wild or Nature Resistance Totem s to substantially decrease the damage from Shockwave and Eyebeams . This helps tremendously in keeping the raid alive , and is well worth the loss of damage output on the boss . The hunters or totems should be placed so that the auras cover the entire room . The first Right Arm tends to die quickly and easily , but things can get messy after that . Use Bloodlust or Heroism when the second Right Arm appears , to keep it from casting Stone Grip more than once . Quotes . Sound files . See " Sound Files of Ulduar : Kologarn " Trivia . Kologarn ' s quotes are a reference to the Black Knight of " Monty Python and the Holy Grail " . Also , the phrase " YOU FAIL " is used by many WoW players as an insult . Kologarn is also seen in the 3 . 1 . 0 Ulduar trailer . It is safe to say he is responsible for driving out the famous explorer Brann Bronzebeard from Ulduar nearly killing him with his eye beams in the process , as that is the farthest in Ulduar he is seen .
