The Jailer, Healer Guide

Updated 1 month, 2 weeks ago for patch 9.2 by Preston. View the change log.

The Jailer Dungeon Journal ModelThis page covers a healer-focused strategy for The Jailer in Sepulcher of the First Ones in Shadowlands. 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, combat log information, and Dungeon Journal information. I'll continue to update it as-needed.

General Mechanics and Abilities

Normal and Heroic

Stage One - Origin of Domination

This stage begins the encounter and ends when The Jailer has control over all Control Pylons through the use of Relentless Domination.

  • The tanks will be dealing with Martyrdom, fixating the current tank and performing a series of attacks.
    • Imprisonment roots the tank in place.
    • Persecution deals moderate damage and greatly increases Physical damage taken.
    • Suffering deals light damage and then light damage over time to all players.
    • At least five players must stack with the tank to split the damage from Misery.
  • When affected by Rune of Damnation, jump inside a Control Pylon hole just before the effect expires to prevent the light damage dealt to and knock back effect on all players.
  • When targeted by Torment, move at least 5-yards away from other players.
  • During Relentless Domination, break line of sight on The Jailer using a deployed Control Pylon.
    • Players in line of sight are mind controlled by Domination, gaining greatly increased health and damage dealt.
    • On Heroic, avoid the path of players targeted by Tyranny.
      • Players hit take light damage and stacking light to moderate damage over time.
  • During Chains of Oppression, run against the pull to remain as far away as possible to lessen the damage taken from Oppression.

Stage Two - Unholy Attunement

This stage begins when The Jailer has control over all Control Pylons and ends when a set of Control Pylons successfully link from the edge of the platform to the Machine of Origination in the center.

  • The tanks will be dealing with Shattering Blast, dealing light damage over time to all players and destroying any Control Pylons within 10-yards.
    • The goal is to keep the Control Pylons from successfully linking for as long as possible.
  • When affected by Rune of Compulsion, move as far away from the edges of the platform as possible before the effect expires.
    • Affected players become hostile and gain a damage absorption shield that must be broken before they're forced to jump off the edge of the platform.
  • During Unholy Attunement:
    • Deals light to moderate damage to all players with Unholy Eruption, depending on the proximity of the Control Pylons to the Machine of Origination.
    • Avoid the Unholy Ground around Control Pylons.
  • Avoid the impact location of Decimator. This knocks back and deals light damage over time to all players.
  • Avoid the additional Tormenting Echo impact locations left behind after Torment.

Stage Three - Eternity's End

This stage begins when a set of Control Pylons successfully link from the edge of the platform to the Machine of Origination in the center and ends when The Jailer is killed.

  • Stack with the player affected by Rune of Domination to split the healing absorption effect from Dominating Will.
    • The healing absorption from Dominating Will must be depleted before the effect expires, or players will be mind controlled by Domination.
  • When affected by Chains of Anguish, run more than 30-yards away from the linked player to break the effect.
    • Breaking a Chain deals moderate damage to all players with Chain Breaker.
  • During Desolation, stand in the impact location to reduce the damage dealt to Azeroth. Players in the impact take moderate damage.
  • Torment now also spawns an Incarnation of Torment.
    • Incarnation of Torment
      • Deals increasing light damage to all players and applies stacks of haste reduction with Cry of Loathing.
  • Avoid the impact location of Decimator. This knocks back and deals light damage over time to all players.
  • Avoid the impact locations of Falling Debris.
  • Avoid the locations of Defile. Each time a player is damaged by Defile, its size grows.

Mythic Differences

Stage One - Origin of Domination

Stage Two - Unholy Attunement

Stage Three - Eternity's End

This stage begins as usual, when a set of Control Pylons successfully link from the edge of the platform to the Machine of Origination in the center, but now ends when The Jailer reaches 10% health.

  • Deals critical damage to all players with World Shatterer.
  • The size of Defile now also grows slowly over time.

Stage Four

This stage begins when The Jailer reaches 10% health, at which point he heals to 24% health, and ends when he's killed.

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

Major

  • Dominating Will causes players to absorb healing, and must be depleted quickly.
  • Chains of Anguish can cause players to need additional healing.
  • (Mythic) Death Sentence (dispel, magic) should be dispelled in a controlled manner, and causes players to need increasing light to moderate healing over time.

Minor
