The Azure Vault
This dungeon comprises four boss fights:
Throughout the fight, you will be trying to manage the number of trees in the area, using different abilities to destroy them.
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.
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.
Throughout the fight, you will be worried about add management.
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:
Arcane Cleave is a frontal cleave. Don't aim this at the group.
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.
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.
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.
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.
Dragon Strike is a large amount of tank damage that should be mitigated.
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.
