Steamvault The Steamvault ( also known as the Steam Vaults ) is the level 70 wing of the Coilfang Reservoir . It is to the left from where you enter the Coilfang Reservoir but not the leftmost - about 11 : 00 . No key is required to enter . You must defeat the first and second bosses and operate the control panels behind them in order to enter the room with the final boss . All mobs give Reputation to Cenarion Expedition through Exalted . Rep Given : Trash : 12 , 2 ( non - elite ) , Bosses : 120 , Full clear 1 , 662 rep . ( 1 , 782 if you take the time to kill all of the slaves as well . ) The fastest path through the instance nets ~ 1100 rep . In Heroic Mode , the fastest path gives roughly 1550 rep , and a full clear will give 2 , 559 rep . The instance can be soloed in normal mode at lvl 80 . Heroic Mode can even be soloed by lvl 80 plate dps . Overview . This is a challenging instance , with an unusually large number of mobs , and a couple of reasonably difficult boss encounters . Trash pulls are made up of 2 , 3 or 4 elite Naga humanoids , of 5 water elementals ( 1 elite and 4 non - elite , ) or of a single elite bog giant . Because of the large number of 4 - humanoid pulls , the instance favors DPS classes that possess humanoid Crowd - Control abilities : Mages , Hunters , Rogues , Warlocks and Shadow Priests . If not all 3 of the group ' s DPS members can CC humanoids , a skilled tank can fairly easily hold more than one mob at once , although in heroic mode this is best left as a last resort ( for broken CC ' s ) to avoid unnecessary wipes . Almost every pull has a slightly different number and combination of mobs . Make sure that casters are taken down right away ( or crowd controlled ) . The melee can usually be saved for last . A large portion of the instance can be skipped if you pull the 2 guards at the entrance followed by the two bog lords on the right and follow around the right hand side . However , you do not get rep for mobs you do not kill . Excessive skipping , as emphasized below , is also highly likely to cause wipes . The Oracles and Sirens are very dangerous , with AoE silence and AoE fear they can block your healer for ten seconds or make you pull extra groups . Typically you want them crowd controlled at first and dealt with after the other mobs are dead . Be aware though if you as a mage polymorph the siren and she breaks early she will be after you . As soon as she gets into range she will try to silence you , making you unable to crowd control , frost nova her etc . If somebody tries to assist you she will cast an AoE fear , so ensure that person can break it , especially if there are other mobs they may be feared into . A Mind Control pull is an effective way to take out a caster early . If you Mind Control the Sorcerer as the pull , then the other mobs will turn to kill the Sorcerer . When you are about 30 % health cast Frost Nova . This will trap the remaining mobs in the pull and allow time for your tanks and other crowd controlling characters to react . This also works in Heroic Mode . Dungeon Denizens . Bosses . See the individual boss pages for more detailed information and strategies . Trash . Warning : Pull Thoroughly . The single most important thing to be aware of for the early parts of this instance is the necessity for thorough pulling . Group leaders in this instance have a tendency to try and rush past various groups of mobs , and early wipes tend to be either due to stray runners triggering other groups of mobs , or members of ranged classes accidentally backing into patrols when trying to get range . Once the group ' s path through the instance has been decided on , it is vital that the group thoroughly clears all mobs within radius of the determined path , if the group wishes to avoid wipes . The group ' s leader should not insist on trying to go around mobs excessively in the name of speed or convenience , since the amount of downtime caused by a wipe will generally be considerably more than the time necessary to ensure a safe path through the instance .
