This dungeon comprises four boss fights:

• 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.

• Azureblade – As security for 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.

• Telash Greywing – 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.

• Umbrelskul – Millenia ago, Umbreskul unwittingly meddled with raw arcane power. Riddled with crystalline growths, he was taken to the Azure Vault until a cure could be found. Sadly, the Vault was sealed away before the research was completed, leaving Umbrelskul sleeping in stasis... until now.

Azure Vault is located in the Azure Span at /way 38.89 64.76.   More information can be found on Wowhead here.

Leymor

Throughout the fight, you will be trying to manage the number of trees in the area, using different abilities to destroy them.

All Roles

•  Ley-Line Sprouts are periodically spawned throughout the fight by Leymor. These must be destroyed using the the other abilities throughout the fight, or your group will wipe to the groupwide damage done by Consuming Stomp. When a Sprout is destroyed, it spawns a Bubbling Sapling, the same oozelings you fought before the boss was activated.

•  Explosive Brand is a knockback done by Leymor which leaves a circle on everyone in the group. When this circle expires, it will destroy any Sprouts inside of it.

•  Consuming Stomp is a groupwide damaging ability that will deal damage based on how many Sprouts are still alive in the room.

Tank

•  Erupting Fissure is a frontal that is targeted on the tank. Once it starts casting, the boss will not turn. This needs to be aimed at as many Sprouts as possible, as it will destroy them.

Azureblade

Throughout the fight, you will be worried about add management.

All Roles

•  Summon Draconic Image summons a dragonkin around the room. This will shoot  Illusionary Bolts at random group members and must be interrupted. These should be dealt with as they spawn.

•  Ancient Orb shoots an orb from the boss in a straight line to the edge of the room in any direction it chooses. You should dodge this as soon as it starts the channel.

•  Overwhelming Energy causes the boss to the run to the center. It will spawn four Draconic Images which channel on the boss, making it immune to damage. You must kill the four images to continue the boss fight. While this is going on, the boss is also spawning 5 Ancient Orbs at a time in a pentagon pattern and shooting them to the edges of the room. These must be dodged the same as the big ones during the main phase of the fight, and look like the image below:

Tank

•  Arcane Cleave is a frontal cleave. Don't aim this at the group.

Healer

• Healers should pay special attention during  Overwhelming Energy, as this causes a lot of unavoidable group damage and can quickly get out of control if you fall behind, leading to a wipe.

Telash Greywing

•  Frost Bomb is a debuff placed on all 5 players. It drops a patch of ice on the floor, indicated by the circle around the player. These will then grow over the next 2 minutes, meaning the group must be conscious of their space that they use. These can be dropped off the platform by players who have an ability to get back onto the platform. Leave a lane in the center to travel through after you drop your orbs.

•  Absolute Zero will cause the boss to teleport to the center of the room and begin a channel. The group must make their way to the safety of a  Vault Rune somewhere on the floor, indicating by a blue bubble.

Healer

•  Icy Devastator is a targeted ability on a random group member that deals a large amount of damage and cleaves around them. This person will need extra focus.

•  Absolute Zero will hit your group extremely hard. You should ensure everyone is topped off, or use something on anyone that you can't top before the detonation.

Umbrelskul

•  Oppressive Miasma is the main mechanic of the fight. It is a stacking slow that ramps up to 50% in total. Players gain a stack every time they move, and should try to avoid getting stacks whenever possible by standing still.

•  Crystalline Roar is a frontal that is targeted at a random player.

•  Unleashed Destruction is a large amount of groupwide damage that comes out somewhat frequently. It should be mitigated when possible.

• Detonating Crystals are spawned randomly by the boss, which must be killed before they finish their  Fracture cast, which leaves a massive DoT on the party if it goes off. It is practically unhealable, so do not let any explode.

•  Arcane Eruption happens whenever the boss reaches 100 energy. It causes  Crackling Vortexs to spawn around the room, which slowly move towards players that can generate healing aggro.

Tank

•  Dragon Strike is a large amount of tank damage that should be mitigated.

Healer

•  Unleashed Destruction will hit your group very hard. You should make an effort to make sure everyone is topped before it goes off.

• The  Crackling Vortexes spawned by  Arcane Eruption will typically hunt you down, as you will be generating the most healing threat. As such, you should try to make big movements to get away from them whenever your slow drops, then plant until it clears again. You will have to be very conscious of your movement choices throughout this fight.
