Dragonflight Season 1 Affix – Thundering

The new Seasonal Affix for Dragonflight Season 1 is Thundering

Throughout the Dungeon, Thundering spawns blue voidzones on the floor that must be avoided by players. Additionally, all players will be affected by a certain buff, that increases their damage and healing done. Three players in your group will be affected by Mark of Lightning, while other two players are affected by Mark of Wind. Tanks will always be affected by Mark of Wind. Coming in contact with the opposite debuff will clear this debuff. If not cleared by walking over a player with the opposite buff will cause the players to be stunned for 8 seconds, taking heavy lightning damage over 8 seconds.

  • Mark of LightningOverloads a player with primal power, increasing their damage and healing by 15% for 15 sec.
    Upon expiration, stuns the player and inflicts 9 Nature damage every 1 sec for 8 sec.

The Arcane Conservatory with Leymor

The first Boss you will encounter in Azure Vault is Leymor. We suggest that you quickly jump downstairs instead of walking from the entrance to reach the first boss room.

Notable Trash Mobs

Make sure to always avoid the patrolling Shrieking Whelp. If they detect you, all the adds turned to stone will start engaging into the fight, dealing heavy group damage and using strong frontal cones to mess with the Tank.

  • Corrupted Lasher will use Mystic Vapors, dealing damage to all players and leaving a debuff on them, dealing heavy periodic damage and stacks. This requires heavy crowd control to make sure to avoid this deadly ability.

  • Arcane Tender will channel Erratic Growth into players, turning them into a sapling with a 5-yard circle around them. Whenever dispelled, other players struck will turn into a Sapling. Make sure to interrupt this spell!

  • They also cause to spawn swirls on the floor with Wild Eruption on random positions. Whenever they land, they turn into Infused Ground, a voidzone that deals damage to players inside of it


The first Boss in Azure Vault is Leymor.

‘Leymor was born of a humble seedling that Malygos found in a pool of ley energy. Once but a small sprout in Sindragosa’s garden, over millenia Leymor has shot up like a weed. Left to its own devices, the looming giant would surely overrun the entirety of the Azure Vault’

Notable Abilities
  • Ley-Line Sprouts are Trees that deal radiating damage in a 5-yards radius, which have to be destroyed by other Abilities.
  • Explosive Brand deals damage to all players, and makes them explode in a 6-yards radius after 6 seconds, destroying Ley-Line Sprouts.
  • Consuming Stomp deals heavy AoE damage to all players. Damage increases by 20% per Ley-Line Sprout alive.

Ley-Line Sprouts

Leymor will frequently spawn multiple voidzones on the floor, out of which Ley-Line Sprouts spawn. Those trees radiate damage in a 5-yards radius around them.

Those Trees have to be destroyed by Explosive Brand and Erupting Fissure, before Leymor uses Consuming Stomp. They cannot be attacked.

Whenever a Ley-Line Sprout is killed, it spawns a Volatile Sapling. Those Adds, when defeated, explode in a very small radius after 2 seconds.



Erupting Fissure

Leymor has a frontal cone, Erupting Fissure, which aims towards the Tank.

As soon Leymor started casting Erupting Fissure, the Tank will no longer be able to control the direction of this frontal cone

This has to destroy as many Ley-Line Sprouts as possible.





Explosive Brand

Whenever Leymor uses Explosive Brand, it deals moderate damage to all players and knocks them away from the Boss.

Players have a 12-yard circle around them, which will destroy all Ley-Line Sprouts hit.

Players have to spread out in order to kill the most Ley-Line Sprout as possible. This is the second and last method to destroy Ley-Line Sprouts.




Consuming Stomp

Consuming Stomp explodes for heavy damage to all party members. This ability deals 20% more damage per Ley-Line Sprout active in the fight.

This Ability can become deadly very quickly if your group hasnt cleared enough Ley-Line Sprouts before.


Infused Strike

Infused Strike strikes the Tank for moderate damage, and leaves a debuff on them, dealing periodic damage over 10 seconds. Tanks must use their defensive cooldowns whenever affected by this.

Crystal Chambers and Azureblade

After defeating Leymor, you fight your way trough multiple stages of the Crystal Chamber. Use the teleports to travel to the next platform to proceed.

Notable Trash Mobs

Players will receive a random buff frequently on their way to the second boss after traveling with the Book of Translocation.

  •  Scornful Haste grants nearby party members 15% Haste, but also grants nearby enemies 30% Haste. Be sure to position well to avoid giving the trash any haste.

The second Boss you will encounter in the Azure Vault is Azureblade.

‘As security of the Vault, Azureblade refused to leave when it was sealed, choosing duty over safety. When the blue dragons failed to return, her bitter resignation drove her to eventual madness. Extending her own life with the magics she was sworn to protect, Azureblade now claims ownership over all the blue dragonflight left behind.’

‘Furious at the blue dragonflight, Telash Greywing is determined to find the secrets that Sindragosa has been hiding in the Arcane Vault. Together with the Sundered Flame, he is certain he will discover more about the origins of the dracthyr… and incriminating evidence against the blue dragonflight.’

After defeating Telash Greywing, you will no longer encounter any enemies, but instead will fight immediatly with the final Boss of Azure Vault.


Last Boss of Azure Vault is Umbrelskul.
