G'huun, Healer Guide

Updated 4 years, 9 months ago for patch 8.1 by Preston. View the change log.

G'huun Dungeon Journal ModelThis page covers a healer-focused strategy for G'huun in Uldir. 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 fight as well as Dungeon Journal information. I'll continue to update it as-needed.

General Mechanics and Abilities

Normal and Heroic

Most of this fight is split between two areas, the Arena Floor and the Upper Platforms. The significance of these in noted for each stage below.

Stage One - My Minion's are Endless

During this stage players will be fighting against G'huun's minions while trying to power the Reorigination Drive. This stage ends once three Power Matrix orbs are deposited into the Reorigination Drive.

  • Arena Floor
    • Attacking G'huun during this stage is useless while Blood Shield is active.
    • When affected by Explosive Corruption, run to the edges of the room to drop the resulting Blighted Ground and release the Virulent Corruption orbs.
    • G'huun periodically summons sets of enemies that must be killed.
      • Cyclopean Terror
        • Targets random players with Torment, dealing light damage over time and slowing movement speed.
      • Dark Young
        • The tanks will be dealing with Massive Smash.
        • At 100% energy, Dark Bargain applies a stack that increases the damage done, healing done, and damage taken by all players and enemies with in 10-yards.
          • Taking two stacks causes players to become Charmed and they will need to be reduced to 50% health to break the effect.
      • On Heroic, Blightspreader Tendril
  • Upper Platforms
    • The upper platforms consist of the ramps and the cliff paths they lead to on the left and right side of the room.
      • It's possible only the left side will be active.
    • Players on the Upper Platforms take constant light damage over time from Unclean Contagion.
    • At the top of the ramp, the Power Matrix orb must be picked up from its platform and brought to the Reorigination Drive at the end of the pathway.
      • While holding the Power Matrix, movement speed is gradually reduced over 10-seconds until the player can no longer move.
      • Use the Throw Power Matrix Extra Action Button to throw the orb to a targeted location.
        • Another player must catch the orb at the location or it will despawn and start back at the beginning.
      • Picking the Power Matrix up from its original platform applies Imperfect Physiology preventing picking it up from the original platform for 5-minutes.
        • Players with this debuff can still catch the Power Matrix from Throw Power Matrix, they just cannot be the ones to initially pick it up from its starting platform.
    • Avoid the Undulating Mass patches.
      • Damaging the Amorphus Cysts temporarily reduces the radius of this effect.
  • Both Areas
    • After three Power Matrix orbs have been deposited, Reorigination Blast deals heavy damage to all players and enemies every 6-seconds for 24-seconds. Additionally, all enemies are stunned and take increased damage.

Stage Two - Behold the Power of G'huun!


This stages begins once three Power Matrix orbs have been deposited into the Reorigination Drive and Reorigination Blast has ended. It ends when G'huun reaches 20% health.

Stage Three - Your Destruction is Assured

This stage begins when G'huun reaches 20% health and ends when its killed.
