Broggok Broggok is the second boss in The Blood Furnace wing of Hellfire Citadel . When first approached , Broggok floats through the air on the far side of a gate with a lever in front of it . The encounter starts when the lever is pulled , releasing four increasingly difficult waves of elite fel orcs . Once each wave is defeated ( or approximately two minutes has passed since the last wave was released ) the next wave will come immediately . Once the fourth wave is defeated , the gate will open and Broggok will come immediately . Strategy . Waves of Orcs . The Broggok encounter is fairly difficult and heavily reliant on crowd control to survive the four waves of fel orcs that come before Broggok himself . Most players thus far have found it helpful to have priests or warlocks use AoE Fear abilities or AoE snares like the hunter ' s Frost Trap or shaman ' s Earthbind Totem as each wave emerges , to give the group a little more time to prepare . There are 4 waves of orcs and they come from each of the four cages on the sides of the room . The cages always open in a specific order , which follows the shape of a " Z " . If you ' re standing at the lever facing the boss in the next room , the first cage that opens is directly to your left . The second is directly to your right . The third is to your left and in the back , and the last cage is to your right and in the back . To start the fight have the tank stand next to the first cage , and have someone else pull the lever . When the cage opens , the tank should then use any AoE abilities such as Consecration ( paladin ) , Swipe ( bear druid ) , Thunder Clap ( warriors ) or Death and Decay ( death knights ) . Each successive cage opens immediately when the last orc from the prior cage dies . To ensure that the tank is the one that will be hit first by each wave , the tank always needs to be standing in front of the next cage door when the last orc in a wave dies , so that the tank is ready to face the next wave . From a tanking perspective , moving the mob to the next door prior to it dying easily makes this part of the encounter much easier . Assign one person in the party as a main assist , so that everyone is attacking the same target to make it easier for the tank to hold aggro , since it can be difficult to quickly mark mobs for a kill / CC order . Then use any CC abilities on the other orcs , as necessary , such as Fear , Freezing Trap , Polymorph , etc . , in order to help the tank with aggro - management and to decrease damage to the tank . You never leave combat between each wave of mobs so there is no time to stop and drink . The non - stop combat puts a heavy strain on mana so it is best to use potions early and have mana regenerating consumables for the encounter , and if there ' s time near the end of a wave use bandages to conserve the healer ' s mana . If possible keep the last orc from each wave CC ' d for a while to give the healers time to regenerate mana and get everyone back to full health . This is especially useful on the last wave since that ' s when the boss enters the room . Broggok . Once the orcs are dead , Broggok himself will enter the room . He drops rings of poison on the ground directly beneath him that will slowly expand outward : the tank and any melee dps will need to move to avoid taking damage from these rings . He also has an AoE poison bolt with a DoT component that will need to be dispelled , if possible . Beware : The poison rings also persist for a time after his death and can still kill party members at that point , so watch where you ' re standing even after the fight is over . There ' s usually a ring that is under is body when he dies , as well , so be careful looting him . Heroic . The boss itself is very similar to normal mode , and the waves of mobs prior to this boss are still a test of endurance . You will need very high sustained DPS and / or multiple forms of crowd control to get through this . In heroic mode each wave and the boss are on a timer to come out ( ~ 2 min ? ) . The waves before the boss , all elite , are also much harder . On the 3rd and 4th waves , there are 4 mobs in each group . The strategy for the waves are otherwise just like that for non - heroic , except : in all but the first group , there will be a fel orc neophyte who is immune to crowd control , but can be snared or feared . He should be tanked and die first , if possible . Just like on non - heroic , make sure that the tank is standing next to each cage door before it opens , so that the tank gets the initial aggro from the wave . From a tanking perspective , moving the mob to the next door prior to it dying easily makes this piece of the dungeon much easier . The door order ( when facing Broggok ) front left , front right , back left , back right . After defeating the waves of prisoners , Broggok himself is a relatively easy fight . Bugs . Helpful hint – Broggok does not seem to be on a timer . He will only come out once the last wave of orcs is dead . If you have a mage , sheep one orc on the last wave and continue to resheep while the healer regains mana and everyone else bandages . However , the mobs are on a timer , and if you take too long - approximately 5 minutes - the next wave of orcs will spawn on you . Appearance . Broggok looks similar to the floating one - eyed cacodemons in the game " " ( with the notable exception that Broggok has multiple eyes ) or the floating multi - eyed tentacled Octobrain from " " . He also resembles the s from the " Dungeons and Dragons " universe , and , in fact , his model is named " Beholder " .
