Blackrock Depths

• Groups of 5.
• Both factions: quests for Alliance, Horde and both. Sources disagree on how many quests there are (27 in Forever data, 38 on a Classic page).
• Time: a full clear takes several hours in the original game.

In the original game:

1. Detention Block: High Interrogator Gerstahn, who drops the Prison Cell Key.
2. Halls of the Law: Lord Roccor and Houndmaster Grebmar.
3. Ring of Law: an arena event. Two waves, then one random boss.
4. The outer depths: Bael'Gar, Lord Incendius, Fineous Darkvire, Warder Stilgiss, Pyromancer Loregrain, General Angerforge and Golem Lord Argelmach.
5. The Grim Guzzler: a tavern, with Hurley Blackbreath.
6. Further in: the rest of the 21 bosses, which our Forever data doesn't name yet.

The Shadowforge Key opens the Shadowforge Gates and the East Garrison Door, and lets you skip the Ring of Law. We check the route in game at launch.

Our sources give no tactics yet. Where each named boss stands in the original game:

• High Interrogator Gerstahn: Detention Block. Drops the Prison Cell Key.
• Lord Roccor and Houndmaster Grebmar: Halls of the Law.
• Ring of Law: an event, not a single boss.
• Bael'Gar: Dark Iron Highway.
• Lord Incendius: Shadowforge City.
• Fineous Darkvire: Hall of Crafting.
• Warder Stilgiss: the Black Vault.
• Pyromancer Loregrain: Shrine of Thaurissan.
• General Angerforge: West Garrison.
• Golem Lord Argelmach: the Manufactory.
• Hurley Blackbreath: the Grim Guzzler.

Take these before entering, or you'll run it twice:

• Burning Steppes (Alliance): Overmaster Pyron (Jalinda Sprig). Pyron is an elite just outside the dungeon.
• Ironforge (Alliance): Kharan Mighthammer (King Magni Bronzebeard, after a chain from Royal Historian Archesonus). You need the Prison Cell Key to reach Kharan.
• Badlands (Horde): Lost Thunderbrew Recipe (Shadowmage Vivian Lagrave).
• Lava pit outside the dungeon (both): Dark Iron Legacy, from the ghost Franclorn Forgewright on his tomb. You must be dead to talk to him, or have the quest shared. It gives the Shadowforge Key.
• Molten Core attunement: Attunement to the Core (Lothos Riftwaker). Take a Core Fragment at the Molten Core portal inside Blackrock Depths. Molten Core has no date in WoW Forever: the developers call it "revamped" and hinted on the official podcast (episode 5, Oct 22, at 77:17; our summary) that its fights will not be the same, without details.
• Inside the dungeon: Jail Break! (Alliance, Marshal Windsor, an escort that is part of the Onyxia chain) and The Love Potion (Mistress Nagmara).

Apart from the attunement, these quests come from pages about the original game: to verify.

• No key to enter, but keys inside: the Prison Cell Key (Gerstahn), the Relic Coffer Key (for the Relic Coffer Doors in the Black Vault) and the Shadowforge Key. One source says Lockpicking 250 opens the same doors as the Shadowforge Key.
• Ring of Law: the final boss of the arena is picked at random.
• Long run: several hours for a full clear in the original game.
• Experience: dungeon quests give much more experience than before, mobs give less (general Forever rule).
