The Black Morass Dungeon Guide

Last updated on Jun 29, 2022 at 14:02 by Abide 3 comments

The recommended level range to run this dungeon on Normal is 68-70. Heroic mode will require Level 70 and the Key of Time Icon Key of Time to enter.

The Black Morass will take approximately 15-25 minutes to complete with an average group. This dungeon is commonly abbreviated as "BM" or "dark portal". This dungeon is unique, as players deal with attacking waves of enemies instead of a normal "walkthrough" dungeon.

In this guide, we will cover dungeon quests, the layout of the dungeon, an overview of trash mobs, tactics for each boss, loot that can be obtained, and ideal group compositions.


The Black Morass Quests

Before heading into The Black Morass, we advise you to get all the dungeon quests related to it. To make this process easier, we have written a separate guide for the quests and their chains.


The Black Morass Entrance Location

Caverns of Time and nearest flight paths

The fastest way to get to the Caverns of Time for both Alliance and Horde will be to fly to Tanaris. From there, follow the image shown above until you find Steward of Time, who will fly you down into the caverns.

When you land, follow the picture below to find the dungeon.

Layout of The Black Morass

The Black Morass layout

The Black Morass is a unique dungeon in its layout. Instead of the standard dungeon where a group will follow a path and fight their way through, The Black Morass has the player standing in a centralized location defending Medivh while he opens the Dark Portal by fighting off waves of incoming enemies.

In the picture shown above, players will start in the north side of the dungeon and head towards the south, fighting Sable Jaguar, Darkwater Crocolisk and Blackfang Tarantula along the way. These are weak creatures that can be killed quickly. When reaching the area marked with an "x", the dungeon encounter will begin.

Periodically, a portal will open at one of the four locations shown in the picture, spawning in a Rift Lord or Rift Keeper and waves of non-elites until the main mob is dead. Shortly after slaying the main rift mob, the portal will close and a new portal will open at one of the other locations. Every 6th wave will spawn a boss instead of a rift mob. This process will repeat for 18 waves at which point the dungeon is cleared.

Sa'at can also give you a Chrono-beacon Icon Chrono-beacon, which you can use to summon a Time Keeper and aid you on a portal. These beacons only work on the trash; bosses will despawn them.

Overview of The Black Morass Trash Mobs

In this section, we will briefly go over each of the trash mobs that pose a threat to you in this dungeon.



While the Rift Keeper or Rift Lord is alive, non-elite mobs will pour in periodically to join in the fight. Below is a quick rundown of their abilities.

If any of these mobs get past your party, they will start to damage Medivh's shield, eventually stopping his cast and essentially "wiping" your group.


Infinite Assassin


Infinite Vanquisher


Infinite Chronomancer


Rift Keeper

There are two versions of this mob, a Mage-type and a Warlock-type.


Mage Version


Warlock Version

These are very dangerous in either version as they both have very strong spells. Make sure to focus them down and interrupt Shadow Bolt Volley IconShadow Bolt Volley whenever possible. Dispel any Fear IconFear or Curse of Vulnerability IconCurse of Vulnerability, if possible.

The Mage version of these need to be tanked away from the range players to prevent Blast Wave IconBlast Wave from hitting more people than needed. Pyroblast IconPyroblast does very high damage, so make sure to keep the tank topped up before these land.


Rift Lord

Make sure to tank these away from the range players to prevent Thunderclap IconThunderclap from hitting more people than needed.


Overview of Bosses in The Black Morass

Here we will give you a full rundown of what you can expect from each of the bosses found here on both Normal and Heroic difficulties as well as the items they drop.


Chrono Lord Deja

This fight has a lot of highly-damaging abilities, especially on the tank. If you have any major cooldowns such as Heroism IconHeroism / Bloodlust IconBloodlust, this is the fight you want to use them on. You should focus on killing the boss as quickly as possible, ignoring the adds until afterwards. Tanks should try to place their back against an object to avoid the knockback from Arcane Blast IconArcane Blast.

Tank the boss in a position where you will not get knocked back far. Remove the Hasten IconHasten whenever possible with spells such as Shield Slam IconShield Slam or Spellsteal IconSpellsteal.

Other than that, quickly kill the boss before Mortal Wound IconMortal Wound stacks too high on the tank and they become unable to be healed.

Make sure to face Aeonus away from the group to prevent the Sand Breath IconSand Breath and Cleave IconCleave from hitting players other than the tank. If you have a Hunter, make sure to remove Frenzy IconFrenzy with Tranquilizing Shot IconTranquilizing Shot.

Aeonus also constantly stuns all players with Time Stop IconTime Stop during the fight. Keep the tank fully healed before this goes out as this can be very deadly if paired with other abilities, especially the Frenzy IconFrenzy and Sand Breath IconSand Breath.

The Black Morass is very straightforward, only having to fight one difficult mob at a time. There are no pulls in this dungeon that require high AoE. High single-target DPS is recommended to quickly deal with the Rift Lords and Rift Keepers.

A Shaman is strong for any Black Morass group. They offer Tremor Totem IconTremor Totem, Grounding Totem IconGrounding Totem and Bloodlust IconBloodlust / Heroism IconHeroism to handle most of the difficult abilities and bosses found in this dungeon. As this dungeon has many non-elite adds, Warrior DPS pulls ahead with their consistent cleave damage and no downtime.
