The Azure Vault Dungeon Guide: Location, Boss Strategies, Trash, and Loot

The Azure Vault is a Level 70 dungeon located in the newly introduced zone of The Azure Span in the Dragon Isles. The nearest flight point for both Alliance and Horde players is the Azure Archives. Upon arriving, move a few steps down until you see the dungeon's entrance.

This guide will focus on an extensive overview of the dungeon, providing vital information to complete it across all difficulties (Normal, Heroic, and Mythic). We will cover all 3 boss fights supported by the most notable trash enemies in the dungeon and their important abilities. If you would like to learn about the other Season 4 dungeons in the upcoming Mythic+ season instead, please see our overviews linked below. Otherwise without further ado, let us begin!

As soon as you defeat the first boss of the dungeon, an NPC will spawn right from where you have entered the dungeon named Sindragosa. She will give you access to teleports throughout the instance, with the first one being after defeating Leymor, the second one to the left after defeating Azureblade, and the last one being just before heading down to the last boss, Umbrelskul. Below you can find their exact locations:

There will be one profession bonus in The Azure Vault from Inscription, located in the later stages of the dungeon (see the map below). In order to activate it, one of your team-members must have at least 25 skills in Dragon Isles Inscription. There is an alternative to having an Inscription and that is to have a Dracthyr at your party. Where to find them? What do they do? How to trigger them? And what is the best use for them? Find out below:

• There will be 2 Tome of Transmogrification throughout the whole dungeon (see the minimaps below to find out the exact locations).
• Using your Extra Action Button will trigger its effect.
• Once you acquire the power, you will gain a Reverse Trap buff, lasting for 2 minutes. Keep in mind there is only one charge of the buff and only one member of your team can get it.
• It works similar to the Polymorph Circles located around the area leading towards Azureblade. Cast it on untriggered "trap" on the ground, let the mobs inside and upon triggering it will crowd-control them.
• It is yet uncertain how much damage exactly you need to do the mobs for the effect to break, but from the initial testing, it seems like it is quite a lot. Uncertain about the target cap on it too.

As soon as you defeat the first boss of the dungeon, Leymor, you will be heading down the stairs towards The Upper Chamber, upon which you will get one of the floor-buffs: Scornful Haste, Viscous Toads, Sluggish Adoration, Shrinking Form, or Hardening Scales to random members of your party after using the first Book of Translocation that you come across. Each of the buffs provide different effects, lasting 1 minute. It is also important to note that there is a possibility of not getting any buff, as it is not guaranteed, and they are exclusively active in the Upper Chamber area (the area before Azureblade). Here is some more information about them:

• Scornful Haste is quite tricky as any member of your party that stays within the 10-yard radius circle will gain 15% Haste, but if enemies stay within, they will gain 30% Haste. Make sure you do not let any nearby enemies get inside!
• Viscous Toads is the less valuable aura, it is good for crowd control as it incapacitates enemies every 10 seconds.
• Sluggish Adoration slows any enemies within 10 yards by 25%.
• Shrinking Form increases your movement speed by 25%, but increases all damage taken by 5%.
• Hardening Scales reduces your movement speed by 25%, but also reduces all damage taken by 5%.

• If you do not stop Shrieking Whelp's Shriek cast, it will activate 2 incredibly powerful mobs: Crystal Fury and Crystal Thrasher. The mobs only trigger if you enter their "aura" and let it finish the Shriek cast, hence why it is important to either stop it or completely walk around it and not engage the mob.
• In case you trigger Crystal Fury, the most important ability you should pay attention to is its Piercing Shards frontal. It all goes in the direction your tank is facing, and if hit, it also leaves a stackable DoT on you; try to stop as many casts as you can with your crowd-control spells.
• Walk out of melee to avoid Crystal Thrasher's Crystalline Rupture, as it will not only do massive damage to you, but also root you. The mob will periodically cast Splintering Shards on a random member of your party. Since this is unavoidable damage, it is an excellent opportunity to use your defensives. Just make sure to have enough distance so that you do not overlap the circles and take even more damage.
• Conjured Lasher is one of the mandatory mobs you will meet along the way to the first boss. They have only one important ability to stop, Mystic Vapors. If you cannot interrupt it, you can use Stun effects (it will not recast!). Multiple Mystic Vapors casts going through are going to turn lethal as the damage-over-time effect stacks, though the good thing is that it is dispellable.
• The last important trash mob is Arcane Tender. You must defeat all 3 them in order to activate Leymor (the first boss). They have 2 abilities, the first being the Wild Eruption projectile, which also leaves Infused Ground ichor on the ground that you must not step in. The second one is Erratic Growth, which must be interrupted. You can also dispel the effect so that you do not have to stay stunned for the full duration!

Upon defeating the 3 Arcane Tenders, the boss, will activate and be ready to be engaged. Here is what you should do:

• Everyone is responsible to clear Ley-Line Sprouts with Explosive Brand. Make sure you communicate about who goes where as the initial slam of the boss will push you back and reposition you.
• Use defensives when the boss casts Consuming Stomp. Remember that the more active sprouts there are, the more damage the boss will do, due to Arcane Power.
• Upon clearing the Ley-Line Sprouts, Volatile Saplings will spawn. They do not do much melee damage, but beware once they explode, as Stinging Sap will deal massive damage to you. Avoid this at all costs.

• Beware of Infused Strike, and use active mitigation to reduce the incoming damage.
• The Erupting Fissure is a frontal spell that will help you clear the Ley-Line Sprouts. Do your best to pre-position the boss so that that it does not cleave any of your party members and also clears as many Sprouts as possible.

• Watch out when Explosive Brand is happening, and make sure people get topped up quickly once it goes through.
• Depending on how many Ley-Line Sprouts are left, you might take more damage from Consuming Stomp. Account for this and use any healing cooldowns if needed.

On the way to the second boss of the dungeon, Azureblade, you will meet more Shrieking Whelps. Do your best to not pull it as it will activate the Crystal Fury and Crystal Thrasher, which are both extremely difficult mobs to deal with.

As soon as you use the first Book of Translocation you will be granted 2 buffs (described earlier in this guide). This can potentially speed up the rest of the trash if done correctly. You should also beware of the circles on the ground, as they will activate once you walk on top of them and polymorph you for 20 sec. You have a small grace period to get out of the circle before you get Polymorphed. The effect is also dispellable! Here are the most notable trash mobs prior to engaging Azureblade.

• Interrupt the Arcane Bolt coming from the Arcane Elemental, but make sure to save an interrupt for Waking Bane as it sleeps you — it is dispellable.
• Sidestep the Forbidden Knowledge cast from Unstable Curator. Failing to do so will disorient you and can quickly lead to death by other mechanics.
• Rune Seal keeper is a dangerous caster that has two important abilities to stop: Condensed Frost and Icy Bindings. Keep in mind that if Icy Bindings goes through, you can always use immunities or root-clearing effects to effect to clear it (Paladin's Blessing of Freedom, Monk's Tiger's Lust, Hunter's Posthaste, etc.), but you should most definitely first look to interrupt it.
• Beware when fighting Arcane Construct, as it will periodically cast Arcane Bash which can knock you off the platform if you are too close to the edge. Move to the middle! They also cast Conjured Barrier, but that should not trouble you as much; you can burn through it!
• Astral Attendant is another important mob to pay attention to. Even though there is nothing to interrupt here, beware of the Unstable Power cast. This, combined with any other effect (Rune Seal keeper's Icy Bindings, for example) will turn lethal.
• Vault Guard is a dangerous "tank-buster" trash mob. Use active mitigation when it casts Ice Cutter. The mob will periodically cast Brilliant Scales, which will make it a lot more resistant to magic damage. Use a Purge effect to remove it.
• Finally, we have the Scalebane Lieutenant. The mob itself will have a tank-buster ability called Ice Cutter (just like Vault Guard), and it will also have a Mage Hunter's Fervor aura, increasing the damage dealt by nearby enemies by 25% if they stay in it, hence why you want to focus it first. The mob will periodically also cast Brilliant Scales, which will make it a lot more durable against magic damage; use Purge effects to remove it.

The boss has 2 phases that he rotates between throughout the whole fight, with the first one being the Summon Draconic Image and Ancient Orb combo, and the second one being the Overwhelming Energy paired with Draconic Illusion. Keep in mind that during the "second phase" you will not be able to damage the boss until you defeat the 4 Draconic Illusion adds, upon which they will stop casting the Seal Empowerment, causing the first phase to repeat. Here is what you should know:

• Periodically, the boss will cast Summon Draconic Image, focus the Draconic Image immediately, while interrupting(Stun effects work too) its Illusionary Bolt cast. Upon defeating the Draconic Image, it will cause Unstable Magic. Do your best to sidestep it.
• Sidestep the Ancient Orb cast.
• During the Overwhelming Energy, sidestep any Ancient Orb Fragments coming your way.
• Fully focus the Draconic Illusion adds during the second phase of the encounter. This is a good place to use your personal defensives. Upon defeating the Draconic Illusion, it will trigger the Unstable Magic ground animation; do your best to sidestep it.

• Beware of how you position Azureblade because of its Arcane Cleave. It has a 10-yard frontal effect, so you should never face it towards your party.
• Do your best to position the boss next to the Draconic Images to allow your damage dealers to effectively "cleave" the add, and deal damage to both targets.

• The Overwhelming Energy phase is going to be the most healing-intensive part of the whole encounter. This is a good place to use your offensive and defensive cooldowns.

Upon defeating Azureblade, head down to the cave where you will be making your way towards the third boss of the dungeon, Telash Greywing. The circles on the ground (the same as the ones in the previous area) will be present on your way towards Telash. Do your best to sidestep them! Here are the most notable non-boss-enemies on your way down:

• Drakonid Breaker's Shoulder Slam targets a random player and charges at them, dealing physical damage. In addition, they also have Bestial Roar which deals heavy group AoE damage.
• Avoid the Null Stomp ground animation coming from Nullmagic Hornswog.
• Beware of Tarasek Looter's Tear Flesh cast; it will deal direct damage and will add a bleed effect to the highest threat target (your tank). Keep in mind that this effect stacks, and can be cleared with Blessing of Protection, Stoneform, etc.

The boss has an additional "intermission" phase called Absolute Zero, used when he reaches 100 Energy. During this phase, he will shield himself with Glacial Shield and spawn a Vault Rune. You must stay under the Vault Rune by the end of the Absolute Zero cast to survive. Failing to do so will probably result in death (unless you use your own immunity or defensive to survive).

At the beginning of the fight, Telash Greywing will have 60 Energy. After each Absolute Zero intermission, he will start at 0. It takes roughly 50 seconds for him to enter his intermission if he starts from 0. Here is the more detailed breakdown of the boss fight:

• The boss will periodically cast Frost Bomb on everyone in your group, followed by Frozen Ground upon expiration. Make sure you do not overlap each other and spread accordingly to avoid additional damage. It is important to also put the bombs close to each other for better space management, due to Frozen Ground.
• Throughout the whole fight, Telash Greywing will cast Icy Devastator on a random member of your party. This is a good place to use your defensives and immunities. Remember that abilities that reset combat can fully neglect this boss mechanic, such as the Night Elf Shadowmeld racial, Rogue's Vanish, Hunter's Feign Death, Mage's Invisibility, and the like.

• Tank the boss close to the Frozen Ground ground puddles to reduce the downtime of your melee DPS, as they put the next puddles close to the existing ones for better space management.

• Be ready to top up your party once the boss has finished his Absolute Zero cast.
• Spot-heal the person that gets Icy Devastator.

Upon defeating Telash Greywing, click on any nearby Book of Translocation (or you can manually drop down) to get to the last boss of the dungeon, Umbrelskul. The boss has 3 tiny intermissions at 75%, 50%, and 25% health where he will become Brittle. Here are further details about the boss fight:

• Once the boss enters the Brittle intermission, immediately focus the Detonating Crystals. This is the highest priority of the whole fight, as failing to do so will apply a group-wide damage-over-time effect called Fracture. Beware that Hardened Crystal has been reworked recently and now does pulsating group-wide AoE damage the longer the Crystallize shield persists, break it as quick as possible!
• Avoid being hit by the Crystalline Roar at all costs.
• Dodge the ground effect coming from the Arcane Eruption cast. In addition, it will create a lingering Crackling Vortex effect that will damage you if you stand in it.

• Use active mitigation when Umbrelskul is casting Dragon Strike.
• Move the boss closer to any Detonating Crystals to allow your damage dealers to effectively cleave them.

• Dispel the tank's DoT from Dragon Strike.
• If Fracture goes through, use your major healing cooldowns to try to recover the situation.
• The boss will occasionally cast Unleashed Destruction, damaging every member of your party; be ready to top them up!
