Vexiona, Healer Guide

Updated 3 years ago for patch 8.3 by Preston. View the change log.

Vexiona Dungeon Journal ModelThis page covers a healer-focused strategy for Vexiona in Ny'alotha, the Waking City. While it's tailored for healers, other roles may also find the information useful. If you have any suggestions or feedback, you can leave a comment below or tweet @PrestonDvorak.

This guide has been updated and maintained based on my own experiences with the encounter, logs information, and Dungeon Journal information. I'll continue to update it as-needed.

General Mechanics and Abilities

Normal and Heroic

During this encounter players will be alternating between stage one and two before eventually entering stage three.

Stage One - Cult of the Void

This stage begins the encounter and ends when Vexiona reaches 100% energy, and begins again following stage two.

  • The tanks will dealing with Despair.
    • While a tank is affected they should be kept as close to full health as possible to reduce the extra damage dealt by Shattered Resolve when the effect expires.
  • Don't stand in front of the boss to avoid Twilight Breath, being hit applies a stack of Void Corruption.
  • When affected by Encroaching Shadows, move as far away from the group as possible to avoid damaging other players and to drop the resulting Shadowy Residue.
  • Dark Gateway deals moderate damage to all players and allows Cultists to enter the encounter.
    • Fanatical Cultist
      • Susceptible to crowd-control. 
      • At 100% energy, Fanatical Ascension turns them into a Void Ascendant (detailed below)
    • Spellbound Ritualist
      • Susceptible to crowd-control. 
      • Interrupt Void Bolt to prevent the moderate damage dealt to a random player.
    • On Heroic, Sinister Soulcarver
      • Susceptible to crowd-control. 
      • Teleports to random players and deals heavy damage over time with Spiteful Assault.
  • Void Ascendant
    • One is active to begin the encounter.
    • Don't stand in front to avoid the Annihilation (dispel, magic) beam.
    • Upon death, leaves behind a Gift of the Void.
      • This should be picked up by a tank who can then use their Extra Action Button to cast Annihilation while also removing all stacks of Void Corruption.

Stage Two - Death From Above

This stage begins when Vexiona reaches 100% energy and ends after three Twilight Decimators have been cast, and begins again following stage one.

  • Encroaching Shadows and Dark Gatewaycontinue during this stage.
  • At the beginning of the stage, a Fanatical Cultist is transformed into a Void Ascendant, which functions the same as in stage one.
  • Avoid the path of Twilight Decimator as Vexiona swoops in a line across the room.
    • Players hit will take heavy damage over time due to Decimation.

Stage Three - The Void Unleashed

This stage begins when Vexiona reaches 40% health and ends when she is killed.

Mythic Differences

All Stages

Stage One - Cult of the Void

  • Dark Gateway summons an additional Cultist type.
    • Iron-Willed Enforcer 
      • Not susceptible to crowd-control due to Iron Will.
      • When targeted by No Escape, be prepared to run at least 10-yards away after being pulled in to avoid Brutal Smash.

Stage Three - The Void Unleashed

  • A Shadow of Vexiona will periodically cast Twilight Decimator, which must be avoided just as in stage two.


Healing Notes

Quick Notes, All Difficulties

The notes below mostly pertain to progression difficulty, meaning if you out-gear the difficulty you're on or use extra healers they may not apply.

Debuffs to Track


  • Despair causes a tank to need critical healing to prevent dealing heavy damage to all players.
  • Decimation causes players to need additional healing.
  • Spiteful Assault causes players to need additional healing.
  • Annihilation (dispel, magic) should be dispelled quickly.
  • Heart of Darkness (dispel, magic) can be dispelled to remove the fear effect.


  • (Optional) Void Corruption causes players to need additional healing.
    • Most players will end up having this in stage three, which could clutter raid frames.

 DBM Settings

Below are the DBM settings I'll be using for Vexiona. You can set them up however you'd like, but these ones should work well as a starting point. Some settings may be Mythic only.
