Blackfathom Deeps Dungeon Guide

Last updated on Apr 05, 2024 at 03:16 by Abide 1 comment

Blackfathom Deeps is a dungeon in Ashenvale that is available to both Alliance and Horde players. We recommend completing the dungeon with a group between Levels 20 and 27. This dungeon will take approximately 1 hour to complete.

The dungeon was once a temple of worship for the goddess of the Night Elves, Elune. Since its destruction during the Sundering, the Twilight's Hammer cult has moved in and now protects a beat of the Old Gods, waiting for it to mature and wreak havoc on Azeroth.


Blackfathom Deeps Entrance Location

The entrance to Blackfathom Deeps is located in Ashenvale, in the corner northwest of Maestra's Post.

Once you reach the temple entrance, jump down into the water below. Swim underwater to the west and then follow the tunnel until you reach the instance entrance.


Blackfathom Deeps Quests

Before setting foot in Blackfathom Deeps, we strongly advise you to get all the dungeon quests related to it. To make this process easier, we have written a separate guide.


Layout of Blackfathom Deeps

Once you enter this instance, head down the tunnel until you reach an open cavern. Here, you will need to jump over the water using the pieces of stone that are lined across the cavern. If you fall off, you will need to go back to the beginning and will likely aggro mobs when doing so.

Once you have cleared this and enter the next chamber, you will find Ghamoo-ra in the centre. After killing him, there are multiple parts of this chamber that are worth exploring before moving on.

  • To the north, there is a chest underwater that contains a quest item for Alliance players, Lorgalis Manuscript Icon Lorgalis Manuscript. Note that there is a long spawn time for this chest, so you will need to wait a total of approximately 10 minutes if every player needs the quest item.
  • To the northwest, there is a cavern that contains Lady Sarevess, the second boss of the instance.
  • To the southwest, there is a cavern that contains Argent Guard Thaelrid, where Alliance players can turn in a quest and both factions can pick up one.

To continue the dungeon, head to the cave to the south and follow the tunnel until you come to a forked section with multiple possible avenues. From where you have come from, the tunnel directly in front of you leads to Gelihast, the next boss. After he is dead, head to the next northern tunnel over to find Lorgus Jett, before moving south once more to continue the dungeon. If you are Alliance, you can skip this, as he is only a kill-target for a Horde quest.

This tunnel will lead you to another open cavern. Before clearing to the end, you should go into the water and swim under the ruins. You will find a stone to summon Baron Aquanis, as well as the boss Old Serra'kis. Once these have been completed, get out of the water and clear through the ruins above ground.

Doing this will bring you to the main temple of the instance and the boss Twilight Lord Kelris. Once he dies, interact with the braziers that surround the statue in the centre of the room. Do these one by one until you have cleared all of them.

The door behind the statue will now open and you can fight the final boss, Aku'mai.


Notable Trash in Blackfathom Deeps

The most important thing to know about the trash in this instance is that they will disarm your tank frequently, so if this happens, your DPS should be very careful about their aggro.

It is also worth noting that the Water Elementals that you have to fight before Aku'mai deal a large amount of AoE damage, so make sure to focus one down as soon as possible to reduce the damage taken.
