City of Threads
City of Threads is a four boss dungeon located in Azj-Kahet. The City of Threads houses a facility used to push Nerubian evolution to its limit, with no concept of an end in sight. This power must be stopped before it reaches beyond the point of saving.
City of Threads has two parts: the city itself, and the Transformatory. Players will start the dungeon by facing Orator Krix'vizk and the Fangs of the Queen. Once these bosses are defeated, players will need to make their way inside the Transformatory where the last two bosses dwell: The Coaglamation and Izo, the Grand Splicer.
The City of Threads is located in Azj-Kahet. With the City of Threads serving as both a dungeon and general zone of Azj-Kahet, players can find the dungeon entrance right on the outside border of the city. The coordinates for the entrance are /way 43.4 12.5, for the City of Threads map, and /way 46.7 69.0, for the Azj-Kahet map. The closest flight point is Wildcamp Ul'ar.
Useful Information
Throughout the Dungeon, there are Shadecasters projecting an image of Queen Ansurek to the locals. Rogues, Priests, and Khaz Algar Engineers of at least Skill 25 can interact with these Shadecasters to give their group a 30 second buff known as Stolen Power. This buff grants increased Damage Done, Healing Done, and Movement Speed!
Upon defeating Orator Krix'vizk, Widow Arak'nai will make mention of how Queen Ansurek has "eyes everywhere" in the city. In order to meet with the Vizier and progress further into the dungeon, players will need to "blind the eyes" of the city.
Make your way across the bridge where you will come into combat with Xeph'itik. Once at half-health, Xeph'itik will yell for mercy and strike a deal with the players, giving a debuff, Pheromone Veil. This masks players' presence in the city while also creating a scent trail to all of Queen Ansurek's hidden guards! Players will need to follow the scent trail, reveal all 4 Eyes of Queen Ansurek, and defeat them in order to meet with the Vizier and progress towards The Fangs of the Queen.
Tactics
Orator Krix'vizk
All Roles
Always stay within the a 10 yards of the boss (or the circle around her). Otherwise, she will cast Chains of Oppression on you, dealing damage and pulling you closer.
The boss will apply 2 Shadows of Doubt to a random members of your party. Use personal defensive when you have the debuff to mitigate the high damage over time effect.
Sidestep the Terrorize frontal.
When the boss reachers 100 energy, she will cast Vociferous Indoctrination cast, dealing massive AoE damage to the entire party; make sure to use your defensive! In addition, she will leave a follow-up ground effect - Lingering Influence, which you must move away from to avoid unnecessary damage.
Tank
Use defensive cooldowns when Orator Krix'vizk is about to hit you with the Subjugate tank-buster.
Immediately after the Vociferous Indoctrination channel, move the boss away to help your team dodge Lingering Influence better.
Healer
When Orator Krix'vizk applies Shadows of Doubt to your party, dispel one of them and spot-heal the other debuff. Make sure all party members are in a good position to dodge the incoming shadow waves after the dispel!
Use healing cooldowns during Vociferous Indoctrination.
Fangs of the Queen
All Roles
During both phases, Nx will continuously cast Knife Throw, leaving a lingering Bleed effect on them.
Outrange the Nx's Duskbringer AoE spell at all costs.
Avoid any ground swirlies during both Phases.
During Phase 1, Vx will cast Ice Sickles, dealing damage to all players (except the tank) and leaving a lingering debuff (can be dispelled) for 12 sec.
Once Fangs of the Queen reaches 100 Energy they will begin their Synergic Step, sidestep their frontals as they will turn lethal on the higher level difficulty. After this, Phase 2 will begin.
Tank
Always do your best to stack both bosses together to allow for a better cleave.
During both phases, Nx will cast Shade Slash tank-buster hit on you. Beware of its follow-up frontal-cone effect Echoing Shade; it will face where you are facing, so ideally not at your team!
During Phase 2, Vx will cast Rime Dagger, use personal defensive to mitigate some of the damage. In addition, ask your party for assistance to stay in the Freezing Blood AoE circle to prevent you from getting max stacks of Frozen Solid and dying.
Healer
Spot-heal people that have Knife Throw Bleed effect.
Dispel as often as you can Vx's Ice Sickles. Any movement-impairing immunity also removes the effect.
The Coaglamation
All Roles
When The Coaglamation casts Vicious Darkness not only will deal AoE damage to the entire group, but will also spawn Orbs of Black Blood. Your team must alternate and soak all of the orbs before they reach the boss to prevent him from healing. Do keep in mind that after each orb soak, there will be a follow-up lingering ground effect that spawns on the ground, and you will receive a stackable Corrupted Coating heal absorb, hence why you don't want to absorb too many in a row.
Outrange the Blood Surge cast (8 yards) and avoid staying in any shadowy ground pulls before the cast as you will take extra damage.
When the boss reaches 100 energy, it will cast Dark Pulse dealing massive AoE damage to the entire party. Here is the best place to use defensives.
Tank
Use your defensives during Oozing Smash tank buster hit.
Healer
Clear as quick as you can the Corrupted Coating from your team members.
Prepare your big healing cooldowns for Dark Pulse AoE channel.
Izo, the Grand Splicer
All Roles
Avoid staying in Shifting Anomalies orbs, as they will also periodically change positions.
Stack during the Umbral Weave cast, as it will be easier to break free from the root effect. If you don't kill it quickly enough, you will end up dying due to Shifting Anomalies changing positions and wiping you.
Outrange the Tremor Slam AoE cast. Make sure to focus the 4 Ravenous Scarabs that spawn afterward, as they will continuously hit your tank with Gorge, generating stacks of their Gorged debuff, and if they reach 5 stacks it will trigger the Gutburst effect.
Tank
Once Izo, the Grand Splicer reaches 100 energy, it will cast Process of Elimination; here is the best time to use your major defensive cooldowns.
Healer
Periodically, Izo, the Grand Splicer will cast Splice to your entire team, be ready to heal it up!
