General Information

On this page, you will find a list of changes between Normal/Heroic modes and Mythic mode, as well as a working strategy to defeat Mythrax the Unraveler in Uldir in Mythic mode.

The other pages of our Mythrax the Unraveler guide can be accessed from the table of contents on the right.


Mythic Mode Abilities


Living Weapon

Shortly after the start of each Phase One, and every minute afterwards Mythrax will cast Living Weapon Icon Living Weapon. This will cause Xalzaix, Mythrax's weapon (an attackable NPC) to be thrown to a player's location, dealing moderate Shadow damage to anyone within 8 yards. Upon reaching 50% Health, Xalzaix will return to Mythrax. Xalzaix does not need to be tanked, but has its own set of abilities.


Void Echoes

Xalzaix will cast Void Echoes Icon Void Echoes once every 8 seconds, dealing moderate Shadow damage to the raid, and increasing by 50% with each cast.


Obliteration Blast

Xalzaix will also cast Obliteration Blast Icon Obliteration Blast, independently from Mythrax's casts of the same name.


Ability Changes


Obliteration Beam

During the second phase, Mythrax will now run to the northernmost point of the room, while Xalzaix will move across the room from him. Mythrax will then channel Obliteration Beam Icon Obliteration Beam at Xalzaix, who in turn will redirect it at a random player.



Mythrax should be tanked in the middle of the room, with the raid spread evenly around him. Ranged should avoid being at max range so they can stay within range of healers. Melee is likely get very crowded, as the healers will need to stay there as well in order to heal the whole group. Raiders need to be keenly aware of when the Oblivion Sphere Icon Oblivion Spheres are spawning so that they can be spread from other players. Spreading out before orbs is the most important part of this fight; healers falling behind due to double mind-controls will be the cause of most wipes.

Once the group has dropped Oblivion Sphere Icon Oblivion Spheres in good places, everyone needs to move in so that Living Weapon Icon Living Weapon can be baited into a spot close to the boss. Xalzaix then needs to be damaged down to 50% as fast as possible, ideally before he is able to cast a third Void Echoes Icon Void Echoes. In between Void Echoes he will also cast Obliteration Beam Icon Obliteration Beam. Make sure your raid is calling out the direction of the beam, as Mythrax's model can often completely obscure Xalzaix from raiders on the opposite side.

Healers should be cycling cooldowns for each Imminent Ruin Icon Imminent Ruin. Particularly strong cooldowns such as Tranquility Icon Tranquility or Discipline Priest ramp should ideally be used when Void Echoes Icon Void Echoes overlaps with Imminent Ruin.

During the transition into Phase Two, Mythrax will run to the northern end of the room and begin casting Xalzaix's Awakening Icon Xalzaix's Awakening. The raid must actively avoid picking up the Existence Fragment Icon Existence Fragments that spawns from this, as the Tanks need all the Fragments they can get. When the N'raqi Destroyers spawn, the Tanks need to pull them to opposite sides of the room, just like on Heroic. The raid should stack up on the left most pile of debris depicted in the image below.

Mythrax Phase 2 Positioning

Each time Obliteration Beam Icon Obliteration Beam begins to cast, the raid needs to move quickly to the opposite piece of debris and stack on top of it. It is vitally important that all members get on top of the debris. This will force all the Visions of Madness Icon Visions of Madness to be spawned on top of each other. Mythrax will cast 4 Obliteration Beams before returning to Phase One.

In the second and third cycles of the fight, it can be a good idea to have DPS players intentionally get hit by Essence Shear Icon Essence Shear in order to generate more Existence Fragment Icon Existence Fragments for the Tanks. If the Tanks notice their stacks are getting out of control, have them call for a DPS to pop a defensive cooldown and soak the following Shear.


Bloodlust/Heroism/Time Warp

We advise you to use Bloodlust Icon Bloodlust/Heroism Icon Heroism/Time Warp Icon Time Warp when Mythrax enters his final "Phase One" cycle.
