This page covers healer-focused strategies for The Azure Vault dungeon 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 tweet @PrestonDvorak.

This guide has been updated and maintained based on my own experiences as well as Dungeon Journal and combat log information. I'll continue to update it as-needed.

Below are guides for the bosses in The Azure Vault, including their abilities, healer notes, and addon settings.

The three nearby Arcane Tenders must be killed to remove Stasis Ritual and activate Leymor.

• Every 45-seconds, creates nine Ley-Line Sprouts at random locations.
  • Ley-Line Sprout
    • Stay more than 5-yards away to avoid the moderate damage over time from Arcane Roots.
    • Must be destroyed using the following boss abilities, detailed below:
      • Erupting Fissure
      • Explosive Brand
• The tank will be dealing with light damage and then light damage over time from Infused Strike.
• Don't stand in front to avoid Erupting Fissure.
  • This destroys any Ley-Line Sprouts hit.
• Every 30-seconds, during Explosive Brand:
  • If any Ley-Line Sprouts are active, players should stand within 12-yards of Leymore to take moderate damage and get knocked back, gaining Explosive Brand.
    • When Explosive Brand expires, it deals moderate damage to all players and destroys all Ley-Line Sprout within 10-yards with Explosive Brand.
  • If no Ley-Line Sprouts are active, stay more than 12-yards away from Leymore to avoid the extra damage.
• Every 45-seconds, deals moderate to heavy damage to all players with Consuming Stomp.
  • Damage dealt is increased by Arcane Power for each Ley-Line Sprout that exists.
  • This destroys all Ley-Line Sprouts.

• Ley-Line Sprouts spawn Volatile Saplings when destroyed.
  • Volatile Sapling
    • Upon death, stay more than 7-yards away to avoid the heavy damage from Sappy Burst.

Mythic+ Affix Notes

• Relatively frequent damage dealt to players can make it difficult to catch up on stacks.

• Use cooldowns on Consuming Stomp.

• Major: Explosive Brand
• Minor: Infused Strike

• Don't stand in front to avoid Arcane Cleave.
• Don't stand in front when she turns to cast Arcane Orb at a random player.
• During Overwhelming Energy:
  • Four Draconic Illusions spawn.
    • Draconic Illusion
      • Makes Azureblade immune to damage with Seal Empowerment.
      • Once all Illusions are killed, Overwhelming Energy ends.
  • Avoid the paths of Ancient Orb Fragments.
  • Deals light damage over time to all players.
• Every 15-seconds while Overwhelming Energy isn't active, spawns a Draconic Image.
  • Draconic Image
    • Interrupt Illusionary Bolt to prevent the light damage dealt to a random player.

• When Draconic Illusions and Draconic Images are killed, avoid the impact locations of Unstable Magic targeted at each player.

Mythic+ Affix Notes

• Draconic Illusions and Draconic Images can cause additional orbs to spawn.
• Several affixes can make avoiding !WcDb? &name=`Ancient Orb Fragment` &id=`390462` &type=`spell`]]s difficult.

• Use cooldowns on Overwhelming Energy.

• There are no particular debuffs to track.

• When targeted by Icy Devastator, stay more than 8-yards away from other players to avoid chaining the damage.
• All players are targeted by Frost Bomb at the same time and should move to the edges of the room while staying more than 5-yards away from one another to drop the resulting Frozen Ground patches.
  
  • Frozen Ground persist for the entire encounter and should be avoided.
• At 100% Energy, about every 60-seconds:
  • Flies to the center of the room and begins casting Absolute Zero.
  • Immune to damage due to Glacial Shield.
  • All players must stand inside one of the blue, protective Vault Rune zones that appears around the room.
  • When Absolute Zero finishes casting, it deals heavy damage to all players not inside a Vault Rune and light damage to all players inside a Vault Rune.

• Vault Runes are deactivated once they've protected a player, meaning players should all stand in the same Vault Rune for Absolute Zero.

Mythic+ Affix Notes

• Orbs could spawn far away from players during Absolute Zero.
• Several affixes can make standing inside a Vault Rune zone difficult.

• Use cooldowns as-needed on Absolute Zero and Frost Bomb.

• Don't stand in front to avoid Crystalline Roar.

• At 75%, 50%, and 25% health, Brittle causes five Detonating Crystals to spawn.
  • Detonating Crystal
    • Attempts to cast Fracture, applying a stacking moderate to heavy damage over time effect to all players.
  • As many Detonating Crystals as possible should be killed before their casts finish to lessen the number of Fracture stacks gained.
• Deals moderate damage to all players and knocks them back with Unleashed Destruction.
• Avoid the impact locations of Arcane Eruption and the Crackling Vortexes left behind.

• Afflicts players with Oppressive Miasma (dispel, magic), reducing movement speed each time the player moves.
  • When dispelled, Umbrelskul gains a stack of Unbridled Power, increasing damage dealt.
  • This can be dispelled as-needed, usually around 13 stacks to ensure players can continue moving effectively to deal with other abilities.
• Brittle now spawns Hardened Crystals in addition to Detonating Crystals.
  • Hardened Crystal
    • Protected by a Crystallize damage absorption shield.
    • Attempts to cast Fracture, applying a stacking moderate to heavy damage over time effect to all players.
