Drest'agath, Healer Guide

Posted 1 week, 2 days ago for patch 8.3 by Preston.

Drest'agath Dungeon Journal ModelThis page covers a healer-focused strategy for Drest'agath 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 killing Drest'agath's Appendages to gain a buff allowing permanent damage to be dealt to Drest'agath.

  • Drest'agath
    • Rapidly heals damage taken due to Aberrant Regeneration.
      • Killing an Appendage of Drest'agath (detailed below) leaves behind a pool of Void Infused Ichor.
        • Touching the pool allows the affected player to damage Drest'agath while the effect persists, avoiding the healing effect.
        • On Heroic, when the effect expires the player gains Umbral Aversion and cannot be affected by Void Infused Ichor for 1-minute.
    • At 100% Energy, Throes of Agony deals heavy damage over time to all players.
      • Killing an Appendage of Drest'agath gives 25 Energy over 5-seconds.
    • If no players are in melee range, Void Grip stuns and pulls in the nearest player.
    • The tanks will be dealing with Volatile Seed.
    • Run as far away from the locations of Entropic Crash as possible to reduce the damage taken.
    • When affected by Mutterings of Insanity, move at least 15-yards away from other players before becoming immobile and triggering Unleashed Insanity.
    • Avoid the Void Glare beams from Drest'agath and Eyes of Drest'agath.
  • Appendages of Drest'agath
    • When killed, Appendages:
    • Eye of Drest'agath
    • Tentacle of Drest'agath
      • Avoid the location of Crushing Slam.
      • At 100% Energy, avoid the Reality Tear as it moves around the room.
      • On Heroic, Void Miasma blocks line of sight into and out of a 10-yard area around the Tentacle.
    • Maw of Drest'agath
      • Deal light damage to random players with Acid Splash.
      • At 100% Energy and while Throes of Agony is being cast by Drest'agath, avoid the impact locations of Spine Eruption.
      • On Heroic, Mutterings of Betrayal places a stack of a healing absorption effect on a random player and any players within 10-yards.
        • This effect must be healed off, at 4-stacks the player becomes hostile due to Betrayed.

Mythic Differences

  • Appendages of Drest'agath
    • Upon death, now also trigger the 100% Energy ability on all other Appendages of the same type due to Throes of Dismemberment.


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



  • Mind Flay causes players to need additional healing.

 DBM Settings

Below are the DBM settings I'll be using for Drest'agath. 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.

DBM settings will be added closer to release.
