Blackrock Depths: Detention Block (Lower) and Shadowforge City (Upper)

Level Range: 47 – 61

Special LFD Notes:

If there IS NO Mole Machine just inside the entrance, you are in
BRD: Detention Block (Lower), you will only need to kill High Inquisitor Gerstahn. Bosses: 1 (2 & 3 optional)

If there IS a Mole Machine just inside the entrance, you are in
BRD: Shadowforge City (Upper)
, you will only need to kill Thaurissan. Teleport to ‘Just Past Grim Guzzler’ using the Mole Machine. Bosses: 8 – 11

The full guide is intended for achievement hunter and completionists to go all the way through from the beginning to the end of the instance.

Special Notes
: Blackrock Depths is a long instance- a really, really long instance. With 14 boss encounters (some encounters have more than one boss), expect to spend at least an hour clearing it.

Moving between the two maps of the instance (‘Detention Block’ and ‘Shadowforge City’) can be confusing. It helps to mentally break it into chunks if you want to remember how to get through it without a map.

Detention Block Part I (LFD: Detention Block): High Inquisitor Gerstahn, Lord Roccor, Houndmaster Grebmar, Grizzle.
Pass through the Ring of Law to get to Shadowforge City.

Shadowforge City Part I (LFD: Shadowforge City): (Optional: General Angerforge, Golem Lord Arglemach, the Grim Guzzler situation), Flamelash, the Summoner’s Tomb situation, Magmus, and Thaurissan.

Shadowforge & Detention Block Part II: Teleport out of the dungeon and then back in to get to the start of the instance. Take the Mole Machine to ‘Into The Domicile’ to hit the Black Vault situation, Incendius, and Bael’gar.

A ‘*’ on the map indicates quest activity.

Thanks to the many friends on Twitter who lent invaluable assistance to this instance.

  1. High Interrogator Gerstahn: Protected by two guards and two dogs. She casts shadow spells- a shield, Shadow Word: Pain, Mana Burnand Psychic Scream- and does melee damage.
  2. Lord Roccor: Pats around the Detention Block area. Clear out nearby mobs before you take him on. Performs melee damage with Flame and Earth Shocks, and a stun Ground Tremor.
  3. Houndmaster Grebmar: Two hound mobs surround him, and two hounds guard him. Try to pull and kill the independent groups of hounds to the left and right of the doorway before engaging him. He performs melee damage with Bloodlust and a Demoralizing Shout.
  4. Grizzle: Walk into the Ring of the Law to start the Ring of Law event. Grimstone opens the three gates surrounding you in succession to release waves of mobs. 1) about 10 Dark Screechers and 2) Grizzle, a large melee troll with Cleave, Frenzy, and Ground Tremor. When he is defeated, the door to the East Garrison will open, which leads to Shadowforge City.
    At the star on the map, unlock the Shadowforge Lock by clicking on it (it’s down a flight of stairs in front of you as you enter from the Ring of Law).
  5. General Angerforge: Surrounded by four guards. Take the guards out first- they’re easy- and then hit the General. He has an Enrage and Sunder Armor, and is melee. Immediately after his death, a mob of seven spawn. Take out the healers first.
  6. Golem Lord Argelmach: Just down the hall from Angerforge is Argelmach. He is guarded by two golems; first take the blue one out, then the pink one. Argelmach himself casts Chain Lightning and Shock and has a Lightning Shield. On to the Grim Guzzler!
  7. The Grim Guzzler Situation: There are four potential bosses in here, and you have multiple options for engaging them. You can
    a) Skip it: It’s long, hard, and difficult to explain to a PUG.
    b) Hurley Blackbreath / Plugger Spazzring / Ribbly Screwpot: Kill Hurley (break all the casks on the lower level to aggro him), Plugger (steal items off the table near him), and Ribbly (just talk to him) as part of both an Ally and Horde quest chain. Killing Plugger or Ribbly has always resulted in a completely aggro’d bar, in my experience.
    b) Private Rocknot Quest /Phalanx: Give Private Rocknot ale from Plugger until he freaks out and starts hitting the large casks, which summons Phalanx, an optional boss. Pull him into the hall outside the Grim to avoid aggro’ing the whole bar (you can do this without killing the other three bosses).
    Don’t fall off the edge of the hall like I did when I was running this instance while researching this map. Put yourself against the wall because Phalanx has a knockback that will throw you off the edge.
    If you fall off, either your group will have to come down and fight Lord Incendius with you, or you’ll have to die and use the Mole Machine transporter to get back.
    d) Leave without killing anyone
    Whatever you do, try not to aggro the whole bar at once.
    You won’t be able to get out once you start killing the three quest bosses. You have to either kill patrons so the guards open the door, perform the Rocknot quest to summon Phalanx, or kill Spazzring for the key.
  8. Ambassador Flamelash: Summons multiple waves of Burning Spirits. When they reach him, they give him a stacking major buff that has no upper limit that I could see. Assign a DPS to kill the spirits before they reach him, and try to burn him down quickly.
  9. Summoner’s Tomb: Challenge Doom’rel to awaken the other seven bosses. They aggro in order on a timer, NOT as the previous boss dies, so kill them quickly: Anger’el (warrior), Seeth’rel (mage), Dope’rel (rogue), Gloom’rel (warrior), Vile’rel (shadow priest), Hate’rel (warlock), Doom’rel (warlock)
  10. Magmus: In the Lyceum, look for the Flamekeepers (red hair, reddish clothing) to get two flames with which to light the two braziers near the door. All the mobs in the room respawn extremely quickly. When Magmus is engaged, golems in the recessed corners will blow fire into the room. Magmus casts Fiery Burst, electrical, and melee damage.
  11. Emperor Dagran Thaurissan and Princess Moira Bronzebeard: Avoid killing Moira Bronzebeard, who will become friendly after Thaurissen is dead. Thaurissen uses Avatar of Flame to become immune to magic damage (he gets larger when this is in effect), and can cast a HoT on himself. There is no need to do a full clear of his throne room.
  12. The Black Vault: Teleport out of the instance and back in to get to the entrance. Take the Mole Machine to ‘Into the Domicile’ and go up the stairs to your right. Clear out the anteroom and engage Warder Stilgiss and Verek. Stilgiss is a frost mage; I take him out first, personally. Open all of the vaults (requiring 12 Relic Coffer keys) to spawn Watchman Doomgrip when the last one is opened. The statues in the room will immediately come to life and start attacking you as well. When he dies, a special slot will open under the final vault to reveal the Heart of the Mountain and a secret safe.
    Just Because BRD Isn’t Confusing Enough: When you read the plaque under the Dark Keeper’s portrait, located just outside the vault room, one of six Dark Keepers will spawn somewhere randomly in the instance, and drops the key to the big Dark Coffer. The name and location of the Dark Keeper who spawned is on the plaque.
  13. Fineous Darkvire: Throws bombs and is protected by three dwarf craftsmen and a golem. Also uses Kick and Holy Strike for major damage; take him and the golem out first.
  14. Lord Incendius: Guards the Black Anvil, if you happen to be an interested Blacksmith. Casts Firy Burst, Firestorm, and Firy Volley, and can knock you off the platform. Put your back against the anvil and push him as close to the edge as you can.
  15. Bael’gar: Summons multiple Spawn of Bael’gars; try to get them down quickly and then go back to hitting Bael’gar. If you don’t have the key to get there from Incendius, just zone out and back in, and run to him from the entrance.

Warrior Says…

If you can finish a full-clear BRD with the same party members you came in with, you can call yourself a real tank.

    Well, it’s a good clear…

    The problem is, you don’t factor in the number one obstacle to completing this dungeon. Player motivation.

    I’m pretty sure that if you run straight from the instance to the High Interrogator (who triggers completion of the lower half) and drop her – half your group is going to immediately drop group and you’ll have to queue up for a new group to keep moving. You’re going to lose at least one party member here – hopefully not your healer.

    Then half your group is going to miss out on quest completions and such.

    Furthermore, your clear pattern finishes off the emperor before sending you after at least four bosses – including Bael Gar. I am really skeptical that anyone will stick with you to clear that stuff after dropping Thaurissan and nailing the achieve for upper.

    As for Heart of the Mountain, I’ve been through this instance a dozen times and never seen a group finish it once. You just never get enough keys. You basically have to kill every dwarf in the entire two instances to have a shot – including the neutral dwarf spectators in the arena.

    I just ran a full clear on both these dungeons two nights ago on my paladin tank, and though I did my job, never lost aggro, and tried to communicate with my party, and downed mobs and bosses quickly – I went through six different people before finishing the place off with Thaurissan.

    As for Lord Incendius, just taunt him away from the anvil into the hallway and tank him there – where he can’t chuck you off the platform.

      although they may have changed it, getting enough keys is simple if everyone is looting. however, your greatest point is motivation. people come in for the completion and leave. i offer to run 101 for people to unlock the rear quest-line but most players don’t know or want to know what i am talking about, but it at least breaks the monotony of that endless number of runs on the city. really the dungeon is great as a whole and should be revised to break the leftover areas into two more dungs. with bael’gar starting one and its completion at heart of the mountain. “the domicile” would need a quest-line but with Moira being removed form the end a set of quests could easily be made as a savior line. even one more place to random would be great but if they do i hope they preserve the look, its just an epic dung that visually should be saved.

    I successfully can call myself a real tank. Not realising that I’d started an Upper City run, we cleared Baelgor, the Warden, then Roccor, then the Arena, then Loregrain, then Fineous, then Incendius, then General, then Arglemarch, then the 3 in the bar, then the Ambassador, the 7 Dreary Dwarves, the giant I can never name, then Thaurissan.

    The only thing that we didn’t do is Doomgrip cause not enough keys dropped. No hunters in the group, so it was friendly and no idiots.

  3. Brian Curtis says:

    I love these maps. You’re doing noble and godly work here for your fellow players. Please continue!

  4. Most people want to get their bonus xp and satchel as quickly as possible.

    Take a look at your group. If you have any character in your group that is less than level 51 then you know you are doing the Detention Block. Once High Interrogator Gerstahn is down your instance is over. If everyone in your group is 51 or higher then you know that you are doing Upper City.

    If you get Detention Block the quickest way to High Interrogator Gerstahn is with the first map above. Once that is done most people will indeed drop group and re-queue.

    The quickest way to get to Emperor Dagran Thaurissan which will complete the achievement and allow everyone to get a satchel is as follows:

    1. Once you pop in to the instance instruct everyone to go to “Just Past the Grim Guzzler”
    2. Walk down to the “Chamber of Enchantment” and kill “Ambassador Flamelash” (
    3. Go through the Mold Foundary. Stick to the bottom half should be all you need to do.
    4. Go in to the Summoners Tomb, talk to Doom’rel and defeat “The Seven” (
    5. Go through the Lyceum. Pay attention to who needs to loot the flame carriers. Since only two flames are required to open the door I recommend lighting the two that are closest to the doors leading to Magmus.
    6. Kill Magmus once the doors are open he is just straight at the end of the hall. (
    7. Once Magmus is down you will be able to enter the Imperial Seat.
    8. Clear trash in there. You do not have to go up the stairs in either direction any more.
    9. Kill “Emperor Thaurissan” (

    People get their Achievement (, Satchel (, and bonus xp and everyone is happy.

    Here is a link to a Map I made of the Quick BlackRock Depths Upper City route explained above. Hope this helps.

    *NOTE: This may not be the most satisfying for all groups as this does limit the number of quests that can be complete. However it does make for the quickest run possible.

    I have long had this question about being able to tell if you are doing detention block or upper city. While the rest of your walkthrough rocks, the mole machine information is not correct. I just tanked a BRD with a mole machine so went to just past grim guzzler and killed the emperor. Got the achievement which is good but didn’t finish the instance. Went back to the beginning and killed the High Inquisitor to finish the dungeon. I think you need to look at whether you have anyone below level 51 in your group to determine which one you are doing .. if so, you are doing detention block. (the poster above me said the same thing but I didn’t see that earlier)
