Mythrax the Unraveler is the penultimate boss of in Uldir.

Mythrax the Unraveler, Bringer of Oblivion, Slayer of Sethraliss: with his mission complete, he returns to his master's side to await further instruction.



Mythrax the Unraveler is a two-phase encounter in which the raid will need to manage a stacking Health reduction debuff. This debuff is applied from most damage sources in the fight, but also generates orbs that will remove stacks of said debuff. Budgeting the use of these orbs, and minimizing the number of stacks taken is key to ensuring a kill.





  • Tank Mythrax facing away from he raid, so no one else is hit by Essence Shear Icon Essence Shear.
  • Gather Existence Fragment Icon Existence Fragments when you are not tanking to keep Annihilation Icon Annihilation stacks low.
  • In Phase Two, pick up N'raqi Destroyers and keep them 40 yards apart and facing away from the raid.
  • Be mindful of how many Oblivion Sphere Icon Oblivion Spheres are in melee and move the boss slightly if too many spawn.


  • Top off players running out with Imminent Ruin Icon Imminent Ruin before they run out of range.
  • Be mindful of how many players get caught in Oblivion Sphere Icon Oblivion Spheres and be ready to use a cooldown if they are broken out too quickly.


  • Use damaging abilities to knock raiders out of Oblivion Sphere Icon Oblivion Spheres if assigned to do so.
  • In Phase Two, focus down the N'raqi Destroyers so the transition back into Phase One is clean.


  • Run to the edges of the room if you are targeted by Imminent Ruin Icon Imminent Ruin.
  • Be ready to dodge Obliteration Blast Icon Obliteration Blast by side-stepping it when Mythrax faces your direction.
  • Be vocal about who you are breaking out of Oblivion Sphere Icon Oblivion Sphere to avoid bouncing players back and forth.


  • Tank Mythrax near the back wall, facing away from the raid.
  • Spread out around the room so no more than one person are caught within Oblivion Sphere Icon Oblivion Spheres at a time.
  • During Phase Two, spread until Mythrax finishes his channel of Xalzaix's Awakening Icon Xalzaix's Awakening, then loosely stack on the N'raqi Destroyers while dodging Obliteration Beam Icon Obliteration Beam.

Bloodlust/Heroism/Time Warp

We advise you to use Bloodlust Icon Bloodlust/Heroism Icon Heroism/Time Warp Icon Time Warp at the beginning of the fight to synergize with cooldowns and potions.
