The Restless Cabal, Healer Guide

Updated 4 weeks ago for patch 8.1.5 by Preston. View the change log.

The Restless Cabal Dungeon Journal ModelThis page covers a healer-focused strategy for The Restless Cabal 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 single stage encounter during which players are fighting against two servants of N'zoth and their relics.

  • Zaxasj and Fa'thuul must be killed at the same time to prevent the healing from Pact of the Restless.
  • Don't leave the central platform to avoid being affected by Enveloping Darkness, reducing healing and damage dealt for 30-seconds.

Relics of Power

  • At 75%, 50%, and 25% health, Zaxasj and Fa'thuul will active the nearest relic.
  • If Zaxasj or Fa'thuul activate the same relic twice, they gain Power Overwhelming, significantly increasing their damage dealt.
  • Void Stone
    • Grants the activating boss Umbral Shell.
      • Until the absorption shield is broken, all players are affected by Embrace of the Void, reducing healing received by 100%.
    • Grants the activating boss Void Attunement, increasing damage dealt.
  • Trident of Deep Ocean
  • Tempest Caller
    • Upon activation, Storm of Annihilation deals moderate damage to all players for 15-seconds and reduces damage dealt.
      • If any player is below 25% health, Annihilate instantly kills them.
    • Grants the activating boss Storm Attunement, increasing damage dealt.

Zaxasj the Speaker

  • Stay at least 5-yards away from other players to prevent Aphotic Blast from affecting too many players at once.
    • On Heroic, when this debuff expires the affected player is then affected by Agent of Demise, becomes hostile to players and takes reduced healing.
  • Avoid the Cerebral Assault cone when Zaxasj turns and casts it.
    • Any players hit will be stunned and become Charmed, and must be damaged to break the Charm effect.
  • Affects a random player with Dark Herald.
    • Standing within 5-yards of the player grants stacks of Promises of Power (dispel, magic), increasing damage dealt while reducing maximum health.
      • This can be dispelled if needed, but maintaining the damage buff for as long as possible is ideal.
        • When dispelled, the dispeller takes moderate damage from Wrack.
  • When Zaxasj activates a relic, a Visage from Beyond joins the encounter for 3-minutes.

Fa'thuul the Feared

  • Tanks will be dealing with stacks of Shear Mind.
  • Stand in the impact locations of Void Crash after they have already bounced two times.
  • During Crushing Doubt, run as far away from Fa'thuul as possible to decrease damage taken.
  • When Fa'thuul activates a relic, an Eldritch Abomination joins the encounter.
    • Continually tries to cast Witness the End.
      • This can be interrupted but should be allowed to finish casting at an opportune time to destroy the Abomination.
      • On Heroic, Witness the Void increases damage taken by all players by subsequent Witness the Void casts for 6-seconds.

Mythic Differences

Relics of Power

  • Void Stone
    • Regularly emits Void Essence when first activated, this effect stops when activated a second time.
      • The Essences pull players towards their center while active.
  • Trident of Deep Ocean
    • Continuously emits Oceanic Essence (dispel, magic) when first activated, this effect stops when activated a second time.
      • Players that come into contact with an Essence are stunned for 6-seconds.
  • Tempest Caller
    • Regularly emits Storm Essence when first activated, this effect stops when activated a second time.
      • Deals steadily increasing damage to the nearest player every 20-seconds.
      • If a player with less than 25% health is hit, Annihilate instantly kills them.

Fa'thuul the Feared

  • Eldritch Abomination


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


  • Promises of Power (dispel, magic) causes players to be especially weak due to the reduced maximum health.
    • It's possible most players will be affected by this at once, making tracking it unnecessary.
  • Oceanic Essence (magic) should be dispelled.


 DBM Settings

Below are the DBM settings I'll be using for The Restless Cabal. 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.
