Garrosh Hellscream ( tactics ) Garrosh Hellscream is the final boss of the Siege of Orgrimmar raid added in Patch 5 . 4 . He has apparently been corrupted and possessed by the Sha of Pride and has split the Horde by heading a new sub - sect called the True Horde . Tactics summary . In phase one , there will be a stack point marked somewhere in the room , depending on the strategy you use . One of the strategies places a marker slightly infront of the exact middle of the circle that Garrosh is tanked in . Every will stack on this point , and when a Desecrated Weapon lands , the DPS are required to quickly kill the weapon so the raid takes minimal damage . After a while , adds will come out , that the tanks need to grab before they aggro onto the DPS . Most of these adds can be taken care of by the Iron Star , if the tanks position them correctly . Shortly after these adds coming out , the Engineers will come out at each side of the room on a raised platform and start summoning an Iron Star . A ranged DPS will be required to kill the left side Engineer , and allow the right side to finish casting . The raid will need to make sure they aren ' t in the path of the Iron Star , but if everyone is on the stack point , they will be un - affected . At some point , Garrosh will teleport you to a Sha - Realm , where Y ' shaarj himself whispers to you . In the Sha realm , you will either have to run straight up the middle and collect all the Sha adds and kill them at the top infront of Garrosh , and then you will be able to engage Garrosh , or you will be put into a realm where you need to divide your raid group into 2 , and group 1 will go left and group 2 will go right . Divide the raid into Groups 1 and 2 beforehand , and make sure you have a healer , tank and 3 dps in each group . Either way , after you have killed the adds in the realm , they will spawn either a lot of small bubbles that will allow one player to run through each and gain a buff to reduce damage by 50 % whilst in the realm , or for the big ones your group must stand around it and then run through it to get the buff . This buff is invaluable whilst killing Garrosh in the realm , as he frequently does heavy AoE damage . After the timer has run out , you will go back into the initial room and begin Phase 3 . At this point Garrosh is actually fuming mad ! Use all of the courage and wisdom you ' ve gained over the past 8 years of WoW to pop bloodlust and burst him down . Strategy . The fight starts with Garrosh summoning Kor ' kron Forces to his side , as well using Iron Stars . Using a ranged dps it is important to kill the ironstar on the left , side of the room , this will result in leaving the right to kill the Kor ' kron Forces . * * * If a Dps / Healer get caught in the Iron star ' s path it will result in an almost instant death . Phase 2 will vary depending on how fast the group is able to get to Garrosh and stop him from becoming empowered . Whiling corruption When this is cast the group needs to spread to one side , for it summons adds that if killed near each other they get stronger and hit much much harder , it is important to try to kill these things alone . This will result in the weapon being unable to be completely killed . Normally this will not occur until Phase 3 of the fight This will cause the mind controlled parties to look different as well as cast faster . It is important to interrupt the casting as soon as possible as well as to dps the Mind controlled players free * * * * CAREFUL OF DOTS , they can in the end be what kills the player that was mind controlled * During phase 3 , Garrosh will get to an extremely low point in his health pool again , causing him to drain more from the heart , becoming fully empowered at this stage he is able to use all of his empowered abilities . It is also the stage that causes many groups to wipe on for they tunnel vision the boss , resulting in the mechanics being left unattended to and ultimately death . This is the last stage of the fight . Quotes . Aggro Power Iron Star Hellscream ' s Warsong Farseer Wolf Riders Memorable Qutoes
