Krosh Firehand Krosh Firehand is an ogre - magi that belongs to High King Maulgar ' s Council of Ogres . Strategy for the mage tank . Unlike most " boss " encounters where tanking is done by a traditional tank , Krosh must be tanked by a mage who is specially geared with high stamina armor . Krosh has a Spell Shield that reduces magic damage taken by 75 % . Mages must Spellsteal this shield to remove it from Krosh and use it to protect themselves from Krosh ' s fireballs while still maintaining aggro with modest DPS . The only exception to this maintained aggro is that it is a common strategy for Warlocks who are Enslaving Olm ' s Wild Fel Stalker s to place them on Krosh to have them disposed of . These Stalker adds may attack the mage tank ' s healer and need to be controlled . The mage ( and the entire raid for that matter ) should be running a threat meter ( Omen ) and you ' ll find that it doesn ' t take that much DPS to maintain aggro even with DPS - impaired gear . This is an important detail for mana management so the mage need not be casting full - time until such time as the raid focuses on Krosh to down him . Before the pull , the mage tanking Krosh Firehand should stand completely to the right of the room and at maximum range from Krosh . Just in front of Krosh Firehand is a slight " clip " where the mage is to stand before the pull takes place . Do not move too close to the " clip " or you will aggro the room . A good reference point is just before the clip , where there is a portion of the wall to the right that makes a " corner " ( with a little steam vent ) that is a safe reference point stay at when preparing for the pull . As High King Maulgar gets pulled , hit Krosh with any ranged instant - cast spell you have ( Fire Blast , PoM - Pyroblast ) or if you time it correctly coinciding with the raid ' s pulling countdown , a Frostbolt , Fireball , or Arcane Blast . Positioning Krosh is easy since when you aggro him , he casts his Spell Shield and will run straight to you until he is right in front of you , then he will stay at that point and repeatedly fireball you stopping only to recast Spell Shield . As he runs toward you , spam Spellsteal . Once he stops and you see the have stolen his Spell Shield , you may want to turn 180° , blink , turn 180° again , and commence your cycle . It is possible to back - up with - out blinking though . You should throw a few spells at him while doing so to build threat and protect your healer who is just as important as the mage tank . It in normal to be slowed while backing up . You are putting distance between him and yourself so that you avoid his Blast Wave attack . Make sure that you position him far enough to the right so the rest of the raid does not have to worry about his Blast Wave ability . If you are fortunate enough to get a Hunter Misdirect make sure the hunter knows NOT to use Arcane Shot as this will dispel the Spell Shield and you will die , and the raid will likely wipe . Hunters should never hit Krosh with Arcane Shot , since the mage must continue tanking even after DPS commences on Krosh by the raid . You are going to need a dedicated healer , or at least one that maintains focus on you along with the ability to get a big heal off rapidly . Krosh will only recast Spell Shield when he isn ' t casting a Greater Fireball ( 3 second cast ) . This means that the tanking mage ' s Spell Shield can fade , and they must be able to take one full damage fireball so they can steal another shield . You are very likely to take several of these during the fight so your healer must be attentive . Greater Fireball hits for 8500 – 9500 damage but can be mitigated by casting Fire Ward / Ice Barrier / Mana Shield just before Greater Fireball hits the tanking mage — the shield ( s ) will absorb their designated damage whether the stolen Spell Shield is up or not , so time it wisely . A healing or mana + healing potion can be taken afterwards and you should wait for those moments to take one . A warlock healthstone can help too and there are items such as , that can help but these share the cooldown with your which you will likely need . All mages taking on the task should study the BC mage stamina gear , which contains a list useful mage gear and other important information on how to prepare before the raid . The mage tanking Krosh should have upwards of 12 , 000 HP when buffed , a good amount of spell hit , and a decent mana pool . The tanking mage should gear for stamina until he reaches a minimum of 10 , 500 health unbuffed ( 13k is more ideal ) . Spell Hit is critical and the mage should be near the full + 16 % spell hit ( 202 rating ) to minimize the chance of having Spellsteal resisted . With 5 points in the Arcane Focus talent you would need just + 6 % spell hit ( 75 rating ) from gear . Mana should not be disregarded , as repeated Spellstealing is costly ( 20 % of your base mana ) . Spell Damage and Crit are good too but are lower priority , as again , it doesn ' t take that much dps to maintain aggro . You should stop casting when the Spell Shield has around 5 seconds left , cast Fire Ward at 3 seconds left , and then Spellsteal when his shield is reactivated . This way , you don ' t have GCD to worry about when you need to cast Fire Ward and the subsequent Spellsteal . You can spam Spellsteal as this does nothing if ' There is nothing to steal ' . Do not cast Fire Ward early because it will be used up even when you have the Spell Shield on you . Save the Fire Ward to help absorb the damage when your Spell Shield is about to fade to reduce the damage from the full Greater Fireball . Raid timer mods such as Deadly Boss Mods and mods which show highly visible buff timers such as XPerl or CTBuffMod are indispensable for this fight . During this time , your focus is on Krosh while the raid is downing the other members of the council . When they are finished they will turn to Krosh , and only then should you DPS at full speed . Another Hunter Misdirect is a good thing to have on you so have one assigned to you even if you didn ' t have one for the pull . After he dies , you can relax and casually DPS until Maulgar is downed . Theoretical . When doing this fight , depending on your timing , it is possible for the tanking mage to never take a full damage fireball . This does seem to be the luck of the draw but with skill , nerve , and low latency it is possible . Here ' s the math : 3 seconds per fireball and a 30 second shield . His cooldown is 30 seconds . He will cast 10 fireballs for a total casting time of 30 secs . After he casts spell shield , wait and watch his casting bar as he casts greater fireball and cast Spellsteal when it is between 33 % and 90 % ( 1 - 2 . 5 secs ) . Therefore his cooldown will expire as he casts his last fireball and just before your shield expires . Rinse and repeat . If your timing is off , he will cast another fireball without a spell shield on either of you and in these cases , a mage should put up his shield ( s ) and then mash the Spellsteal key . Quartz is another useful addon for this kind of timing and includes an integrated casting latency timer . The time it takes between when you hit Spellsteal and when the server actually registers it needs to be taken into account while doing this . If you ' re in the yellow , I wouldn ' t try it and just go for the key mashing approach .
