Uu'nat, Harbinger of the Void, Healer Guide

Updated 2 weeks, 3 days ago for patch 8.1.5 by Preston. View the change log.

Uu'nat, Harbinger of the Void Dungeon Journal ModelThis page covers a healer-focused strategy for Uu'nat, Harbinger of the Void in the Crucible of Storms. 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

This is a multi-stage encounter during which players use the Relics of Power against Uu'nat, his minions, and the power of N'zoth.

Relics of Power

  • Some of these Relics are used to counter boss abilities or mechanics, which will be explained in the relevant sections of the boss' abilities.
  • Currently, I'm assuming activating a relic gives an Extra Action Button that will use that relic's effect, but I'll update this once more data is available.
  • Void Stone (Healers)
  • Trident of the Deep Ocean (Tanks)
  • Tempest Caller (DPS)
    • Upon activating the effect:
      • Storm of Annihilation deals moderate damage to all nearby players and non-boss enemies every 1-second for 15-seconds.
        • Any players or enemies that are damaged below 25% health are instantly killed by Annihilate.
          • The prevents enemies from triggering on-death effects.
    • Each DPS can only activate the Relic once, due to Feedback: Storm.

Stage One - His All-Seeing Eyes

  • Uu'nat, Harbinger of the Void
    • Don't stand in front of the boss to avoid Touch of the End.
      • Additionally, this causes all Undying Guardians to flock towards the affected area.
    • Avoid the Oblivion Tear if possible.
      • Coming in to contact with the Tear spawns a fragment that moves towards Uu'nat, healing it upon impact.
        • Healers can prevent this healing by using Void Stone / Embrace of the Void before the fragments reach Uu'nat.
    • Soak the impact locations of Void Crash after it has bounced two times.
    • Periodically calls upon the Eyes of N'zoth to harass players.
      • Maddening Eyes of N'zoth causes any eyes that open to launch a void beam straight out from themselves.
        • Any player hit will become hostile for 8-seconds.
      • Piercing Gaze of N'zoth causes any eyes that open to sweep the area with sections of void energy.
        • Any players hit will take moderate damage over time.
    • At 100% Energy, Gift of N'zoth: Obscurity deals moderate damage to all players.
      • Avoid the expanding void zone this leaves behind.
  • Undying Guardian
    • Keep these at least 10-yards away from Uu'nat to prevent the reduced damage taken from Sightless Bond.
    • Shroud of Whispers prevents these from being killed and reduces the damage they deal when at lower health.
    • Upon reaching 1 health, Unnatural Regeneration gradually heals them back to full health.

Stage Two - His Dutiful Servants

Stage Three - His Unwavering Gaze

Mythic Differences

Relics of Power

  • Unstable Resonance periodically affects all players with a Storm, Ocean, or Void mark.
    • Players must click on the Relic that corresponds to their debuff within 15-seconds to avoid triggering a fatal explosion.
    • Touching a player affected by a different debuff will also trigger a fatal explosion.

All Stages

  • Undying Guardian
    • Periodically gains a stack of Hunger for the End, increasing movement speed and damage dealt.
      • At 15-stacks, these can no longer be crowd controlled.
    • At 100% energy, Feeds on a player, dealing heavy damage and healing for part of the damage dealt.
      • It's possible this can be countered by incapacitating crowd control effects.

Stage Two - His Dutiful Servants

  • Primordial Mindbender
    • Periodically gains a stack of Hunger for the End, increasing movement speed and damage dealt.
      • At 15-stacks, these can no longer be crowd controlled or interrupted.
  • Swarming Voidspawn
    • Periodically gains a stack of Hunger for the End, increasing movement speed and damage dealt.
      • At 15-stacks, these can no longer be crowd controlled or interrupted.
    • Periodically Voidsteps to a random player's location.

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.

 DBM Settings

Below are the DBM settings I'll be using for Uu'nat, Harbinger of the Void. 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.
