Uldir Boss Guides » G'huun Guide

G'huun is a boss in the Uldir raid in World of Warcraft. Our strategy guide will help you to defeat the G'huun encounter and the loot listing below contains all of the loot he drops on each difficulty.



Overview

G’huun is the last boss of Uldir, and presents some unique encounter design and mechanics. This is a three phase fight that requires extensive raid coordination, especially in the first two phases.

Heroic Changes


Strategy and Positioning

  • Positioning and strategy of this encounter will greatly vary depending on the phase the boss is in, and the roles the players have.

Phase 1:
  • The boss will remain in Phase 1 until three Power Matrices are brought to the Reorigination Drive.
  • Each side has an upper platform, and should have a group of 2-3 players assigned to move the Power Matrix. The first Power Matrix will spawn on the left side, and after successfully delivered, the next will spawn on the opposite side.
  • The groups who move the Power Matrix should pick it up, move as far as possible with the aid of movement boosting abilities, then throw it maximum distance to the next player. The Amorphous Cysts should be damaged to reduce the area of the slow.
  • In the lower area adds will spawn in waves. These need to be managed and killed until the upper platform groups complete their tasks.
  • Players with Explosive Corruption should move to the edges of the room to make it easier for others to dodge it.
  • The Dark Young adds will cast Dark Bargain, which players should stand in to gain the damage increase. Note that only every other one can be soaked to gain the buff, otherwise the player will become mind controlled.

Intermission:
  • Right after the third Power Matrix reaches the core, the raid should stack up to make healing easier, and finish off any adds still present.

Phase 2:
  • The raid should be spread at least 5 yards apart from each other to minimize the damage Wave of Corruption does.
  • Players should take turns cleansing their Putrid Blood stacks by standing near a player affected by Blood Feast. Only a limited number of players should do this at a time to manage the stacks of Blood Might the Gibbering Horror will gain.
  • The upper platform teams should still run the Power Matrix the same way as Phase 1.

Phase 3 (15 - 0%):
  • The upper focusing crystal is destroyed, and all players should move down to the lower platform.
  • Collapse will cause debris to fall which deals fall off damage. Stand as far from it as possible.
  • When the boss casts Gaze of G’huun, the whole raid should turn away from him to prevent being feared.
  • All other abilities from Phase 2 carry over to Phase 3.

Strategies by Role


All Roles


DPS


Healers

  • Players targeted by Torment will take increasing damage, and will require spot healing.
  • There will be large raid damage during the short intermission.
  • Phase 2 and 3 will deal increasing damage to the raid, especially in the last 15%.
  • Tanks will take increasing damage until they swap. They will take the highest amount of damage just before swapping.

Tanks

  • In Phase 1, only one tank is needed on the lower platform. This tank needs to aggro the Dark Young add, and move it near the Cyclopean Terrors and Blightspreader Tendrils.
  • In Phase 2, the boss should be tanked around the center of the room, and tanks should swap as frequently as needed to survive the Corrupting Bite, and Growing Corruption damage. The number of stacks will vary from tank-to-tank.
  • The taunt swap mechanic remains the same in the last phase as well.
  • Gibbering Horror adds should be picked up as they spawn.

    Upon reaching low health, G'huun unleashes his might, destroying the Reorigination Drive, preventing the use of Reorigination Blasts.
