Star Augur Etraeus is one of the 5 bosses that can be fought in an order of the raid's choosing.

The nightborne astromancer Etraeus has devoted long years of research to scouring the skies of Azeroth, seeking answers to the great mysteries of the universe. His scrying has shown him worlds beyond our ken, and the power of the Nightwell allows him to draw upon the essence of those worlds to amplify his own powers.



Star Augur Etraeus is a 4 phase fight that emphasizes coordination above all else. The majority of the fight is a single target encounter, though he will occasionally summon a powerful adds to assist him. As the raid gets further into the fight he showcases his mastery over the magics of Frost, Fel, and Void.

  • Clear the pools of Felflame Icon Felflame with the Fel Impact Icon Fel Impact cast.
  • Perform a taunt swap at 4+ stacks of Felburst Icon Felburst.
  • Perform a taunt swap at 5-7 stacks of Voidburst Icon Voidburst to avoid excessive damage when it expires and spreads.
  • Get out of the group with Void Impact Icon Void Impact to spawn the Thing That Should Not Be. Ensure it is far enough from the boss to avoid Void Shift Icon Void Shift being applied to both targets.


  • Heal players through the heavy damage sustained by Coronal Ejection Icon Coronal Ejection.
  • Have raid cooldowns prepared for Fel Nova Icon Fel Nova as it deals heavy raid wide damage.
  • Heal players affected by Voidburst Icon Voidburst as it spreads through the raid.

Mythic Notes

  • Match with players of the same star sign when Grand Conjunction Icon Grand Conjunction is cast. Avoid players with other star signs; a collision with a star sign that does not match or your sign expiring (10 seconds) will result in a Grand Trine Icon Grand Trine (always a raid wipe).
  • The Shatter Icon Shatter from Icy Ejection Icon Icy Ejection will now leave behind an ice crystal that emits a Frigid Pulse Icon Frigid Pulse. The pulse deals heavy Frost damage to anyone with 5 yards and stuns them for 1.5 seconds.
  • Fel Ember Icon Fel Ember causes a meteor to slowly fall from the sky, dealing heavy Fire damage and creating several patches of Felflame Icon Felflame upon impact.
  • World-Devouring Force Icon World-Devouring Force occurs once a minute in the final phase. An eye manifests, firing a beam through the center of the platform in a line that will instantly kill anyone hit by it. It will also leave behind an untargetable eye that damages players periodically.

Bloodlust/Heroism/Time Warp

Bloodlust Icon Bloodlust should be used in Phase 4, as it is the most difficult phase of the fight, and must be finished quickly before the raid damage from Voidburst Icon Voidburst becomes too lethal. It is recommended to use it on the first Thing That Should Not Be to kill it as quickly as possible.
