City of Threads Dungeon Guide: Location, Boss Strategies, and Trash

City of Threads is a max-level dungeon located on the South-West side of Azj-Kahet, Khaz Algar.

This guide will be an extensive overview of the dungeon, providing vital information on how to complete it across all difficulties. We will cover all 4 Boss fights, as well as the most notable trash enemies in the dungeon and their important abilities. If you would like to learn about the rest of the dungeons in The War Within Season 1, please see our overviews linked below. Otherwise, without further ado, let us begin!

• There are 4 locations exclusively located in the first area of the map (see the screenshot below) of where you can obtain the dungeon buff once you interact with Queen Ansurek.
• You must have either Priest, Rogue or The War Within Engineering above 25 Skills.
• After a few seconds of triggering the Queen Ansurek, she will grant the entire party a 30 sec Stolen Power buff, increasing your damage and healing done by 15%, as well as, movement speed by 50%.

• Sureki Venomblade will only be dangerous for your tank due to its Venom Strike and otherwise will be harmless to your team.
• Interrupt as many Sureki Silkbinder's Web Bolts as you can. In addition, use any disturbing effects for their Silk Binding channel before it completes. Otherwise, you will trigger its follow-up effect Silk Binding.
• Use defensive cooldowns when Royal Swarmguard casts Ravenous Swarm (it will apply the DoT effect to your entire party). In addition, sidestep their Earthshatter frontal.
• Interrupt Herald of Ansurek's Twist Thoughts at all costs. In addition, she will apply Shadows of Doubt to a random party member; upon removal or expiration, it will shoot 4 waves of Doubt which deal a lot of damage and stun you for 3 sec.

• 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.

• 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.

• 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.

Before even getting close to the rest of the mobs, you first must defeat Xeph'itik, which will grant you with Pheromone Veil buff allowing you to pass through this area freely. He has several important abilities to watch out:

• Interrupt Web Bolt.
• Sidestep its Gossamer Barrage ground swirlies.
• Dodge the incoming Perfume Toss ability.

After you pass Xeph'itik, you must find and defeat 4 Eyes of the Queen@ hidden inside this part of the dungeon. Pay attention to the nearby ground visuals (check the screenshot below) as they will give you hits if you get closer to their location. In addition, make sure the sentries don't catch you (check screenshot below)otherwise, you will take damage from Web Wrap and be sent back at the start of the event where Xeph'itik was slain! Here is what their abilities do:

• When dealing with Eye of the Queen, use defensive if you are targeted by Void Rush and avoid their shadowy frontal cone.
• Interrupt Covert Webmancer's Grimweave Blast and use your stops for the Mending Web healing ability.
• Web Marauder will only really be dangerous for your tank due to its stackable debuff - Rigorous Jab.

Once you have defeated the 4 Eye of the Queen, walk close to Executor Nizrek (located on the right side of that area) to trigger the final event before activating Fangs of the Queen, the second boss.

Fangs of the Queen is one of the hardest multi-phase encounter across all Mythic+ dungeon for this season, consisting of Vx and Nx. Both bosses share Twin Fangs passive, which eases the fight as you can target only one of them instead of constant swapping. The fight becomes much harder once we enter Phase 2, requiring much better coordination than the previous phase. More information, down below:

• 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.

• 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.

• 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.

After you have defeated Fangs of the Queen, a check-point will unlock, allowing you to transfer from the start of the dungeon (where you resurrect after death) to where you have slain Fangs of the Queen by using Trained Flyer located to the right of you upon spawning.

• Sureki Conscript will deal Brutal Jab to your tank and otherwise, be harmless to your team.
• Beware of Agile Pursuer's Knife Throw as multiple casts can turn lethal.
• Royal Venomshell is the hardest mob in this area due to its Earthshatter frontal and mass Poison effect - Venomous Spray supplemented by ground swirlies.
• Interrupt Sureki Unnaturaler's Void Wave otherwise they will deal AoE damage and knock your party away, which can accidentally trigger any nearby cocoons, spawning extra mobs.
• At last, when engaging Unstable Test Subject, pay attention when he is channelling Dark Barrage as it spawns ground swirlies, which you must avoid! In addition, he will also do Fierce Stomping dealing large AoE damage to the whole group.

• 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.

• Use your defensives during Oozing Smash tank buster hit.

• Clear as quick as you can the Corrupted Coating from your team members.
• Prepare your big healing cooldowns for Dark Pulse AoE channel.

• Interrupt Elder Shadeweaver's Web Bolt and stack during Umbral Weave as it will be easier to damage the webs and brake free.
• Use defensive cooldowns during Hulking Warshell's Ravenous Swarm. In addition, outrange its Tremor Slam cast (12 yards) and focus the 4 incoming Hungry Scarabs (they only deal auto-attacks to the tank).

• 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.

• 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.

• Periodically, Izo, the Grand Splicer will cast Splice to your entire team, be ready to heal it up!
