The Amalgamation Chamber, Healer Guide
Updated 2 weeks, 6 days ago for patch 10.1 by Preston. View the change log.
This page covers a healer-focused strategy for The Amalgamation Chamber in Aberrus, the Shadowed Crucible in Dragonflight. 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 contact me.
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 - Shadow and Flame
This stage begins the encounter and ends when the Essence of Shadow or the Eternal Blaze reaches 50% health.
- Shared Abilities
- On Heroic, must be kept more than 25-yards away from one another to avoid the greatly increased damage dealt effect from Elemental Instability.
- Essence of Shadow
- The tanks will be dealing with extra light damage from Shadow Spike.
- When targeted by Umbral Detonation, move as far away from other players as possible to drop the resulting Lingering Umbra and to avoid chaining the damage dealt. Players in the area take light damage over time.
- Every 20-seconds, during Coalescing Void, move as far away from the Essence of Shadow as possible to reduce the damage taken.
- On Heroic, avoid the paths of Shadows Convergence as they move towards the Essence of Shadow. Players hit take moderate damage.
- Frequently applies a stack of Corrupting Shadow to all players within 50-yards, reducing maximum health and dealing light damage over time.
- Eternal Blaze
- The tanks will be dealing with extra light damage from Flame Slash.
- Don't stand in front when it turns to cast Swirling Flame, targeted in the direction of a random player.
- Stand in the impact location of Fiery Meteor to split the damage dealt.
- Four players splitting the damage should be sufficient, with each player taking moderate damage.
- If no players are in the impact location, all players take heavy damage.
- On Heroic, every 20-seconds, during Molten Eruption, one player must stand in each impact location.
- Players in an impact take light damage from Molten Eruption
- If an impact fails to hit a player, all players take light damage from Molten Destruction.
- Frequently applies a stack of Blazing Heat to all players within 50-yards, dealing stacking light to moderate damage over time.
Intermission One - The Amalgamation
This intermission begins when the Essence of Shadow or the Eternal Blaze reaches 50% health and ends after about 10-seconds, when the Shadowflame Amalgamation appears.
- Enemies are effectively immune to damage due to Crucible Instability.
- Avoid the impact locations of Splintered Flames and Splintered Shadow.
Stage Two - Destruction Perfected
This stages begins after about 10-seconds in intermission one, when the Shadowflame Amalgamation appears, and ends when the Shadowflame Amalgamation is killed.
- The tanks will be dealing with extra light damage and the greatly increased Shadowflame damage taken effect from Withering Vulnerability.
- Don't stand in front to avoid Shadowflame Burst, targeted on the current tank. Players hit take moderate damage.
- When targeted by Blistering Twilight, move as far away from other players as possible to drop the resulting Engulfing Heat patch and avoid chaining the damage dealt. Players in the area take moderate damage over time.
- Avoid the paths of Swirling Shadowflame tornadoes emanating out from affected players. Players hit take light damage.
- Every 40-seconds, during Gloom Conflagration, at least five players must stand in the impact location.
- Five players splitting the damage should be sufficient, with each player taking moderate damage.
- If fewer than five players are in the impact location, all players take likely-fatal damage.
- Immediately after the impact, move as far away from its location as possible to reduce the damage taken from the subsequent Gloom Combustion explosion.
- On Heroic, every 40-seconds (in between Gloom Conflagrations) , during Convergent Eruption, one player must stand in each impact location.
- Players in an impact take light damage from Convergent Eruption.
- If an impact fails to hit a player, all players take moderate damage from Convergent Destruction.
- Immediately following an impact, avoid the paths of Convergent Orbs as they move towards the impact location. Players hit take moderate damage.
- Frequently applies a stack of Shadowflame Contamination to all players, reducing maximum health and dealing stacking light to moderate damage over time.
Mythic Differences
Stage One - Shadow and Flame
- Players with Corrupting Shadow and Blazing Heat should avoid touching players with the opposite debuff.
- If two opposite debuffs touch:
- All players within 5-yards take light damage from Volatile Shadowflame.
- The player with Corrupting Shadow gains a stack of Lingering Shadows, increasing Shadow damage taken and dealing stacking light damage over time.
- The player with Blazing Heat gains a stack of Lingering Flames, increasing Fire damage taken and dealing stacking light damage over time.
- If two opposite debuffs touch:
Intermission One - The Amalgamation
- Players with both Corrupting Shadow and Blazing Heat trigger a Volatile Shadowflame at their location, gaining a stack of Lingering Shadows and Lingering Flames.
Stage Two - Destruction Perfected
- Every 45-seconds, during Shadow and Flame:
- Stay more than 6-yards away from other players to avoid chaining the damage dealt.
- Each player gains a stack of Corrupting Shadow or Blazing Heat, which functions the same as in stage one.

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.
- Use Major Cooldowns
- stage one: as-needed to deal with the increasing damage dealt by Corrupting Shadow and Blazing Heat
- stage two: on Gloom Conflagration [occurs every 40-seconds]
- Use Minor Cooldowns on
- stage one: Coalescing Void/Molten Eruption [occurs every 20-seconds]
- stage two: Convergent Eruption [occurs every 40-seconds]
- Pre-heal Before (mainly for heal over time classes)
- in genral, heal over time effects should be kept active due to the persistent damage throughout the encounter
- Potion of Frozen Focus use
- likely just as intermission one ends
- Other things to watch for
- Damage increases steadily the longer the encounter goes on, in addition to players having less maximum health.
Debuffs to Track
Major
- Withering Vulnerability can cause the tanks to need additional healing.
