    Disclaimer: This fight uses the default taunt rule set, which means that a duration of 20 seconds with no casts of taunt is required for the Diminishing Returns to reset on it. Therefore you will need to wait 20 seconds between taunt casts (if you do not do this 5 times, the boss will be taunt immune)

    Fight Summary

    There are two bosses in this encounter: Zaxasj the Speaker (Ranged), and Fa'thuul the Feared (Melee). 

    At 75%, 50%, and 25% the boss will activate the nearest relic to them. Each boss should only empower each relic once (3 relics each, 6 relics total), when they activate a relic they gain a 10% damage buff (this stacks up to 3 times). If they activate the same relic twice in a row they will gain a 300% damage increase buff called Power Overwhelming.

    These bosses do not share health and will need to be killed at a similar time. When one of them reaches 1 health it will attempt to cast Pact of the Restless, which if completed will heal the boss back to 20%. Get both bosses to 1 health to interrupt the cast and end the encounter.

    Zaxasj the Speaker

    You will ideally want a ranged DPS player to be tanking this mob.

    The main ability for this boss is Aphotic Blast - This will deal less damage the further away the target is from the boss, and leave a debuff on the target and anyone within 5 yards.

    This debuff will increase threat generation by 150%

    [Heroic] When the Aphotic Blast debuff expires it will transform that player into an Agent of Demise. Once a player is an Agent of Demise they will received reduced healing by 75% and they will be hostile* to the raid.

    Cerebral Assault - Zaxasj will face in the direction of a random raid member and begin the 6 second long cast. The cast is in narrow cone from Zaxasj to its target. Players will need to move out of this cone before the cast ends, if they are not able to move out of the cone they will take shadow damage and be hostile* to the raid for 4 seconds.

    *Hostile to the raid - When a player is hostile to the raid they will not be able to be targeted by healers, and will be able to attack all raid members (and all raid members will be able to attack them).

    Dark Herald - Zaxasj will place this debuff on a non-tank player and every 5 seconds if anyone is near this player they will receive Promises of Power. This will give players a stacking 10% damage buff, however they will also lose 10% health each stack.

    [Heroic] When Promises of Power is dispelled, it will deal damage to the dispeller in the form of Wrack.

    Relic Add

    When Zaxasj activates a relic it will also cast Visage from Beyond. This spawns an add called Visage from Beyond which will cast Terrifying Echo (15 second cast), which will fear everyone in the raid. The only way to interrupt this cast is to bring the add to 1 health.

    However, when it reaches 1 health it will cast Coalesce Void and regenerate health at an increasing rate over time. It will not carry on casting until its back to full health. You are still able to attack it whilst its regenerating health.

    This add lasts 3 minutes.

    Fa'thuul the Feared

    Shear Mind - This is the stacking tank mechanic of the encounter. You will take a large amount of physical damage and have your stats reduced by 10% for 30 seconds per hit.

    Void Crash - When cast several void zones will appear in the room. These deal large shadow damage to anyone within the area, however each time they bounce they will deal less damage. After two bounces they are at their lowest and should be soaked by a single person to remove it.

    Crushing Doubt - Two players will be marked and receive a 12 second debuff.  During this debuff they are slowed by 25% and will take increasing amounts of damage until the debuff expires at which point it will deal Shadow damage to the raid which is based on your distance from that player.

    Relic Add

    When Fa'thuul activates a relic it will cast Eldritch Revelation which will spawn three Eldritch Abomination Adds.

    These adds will all cast Witness the End. This is a 9 second cast which when complete will cause the add to die and deal Shadow damage to the raid.

     

    You will want to stagger these deaths by interrupting, silencing or stunning the adds.

    For example:
    Interrupt Add 2 + 3 - Add 1 dies
    Interrupt Add 3 - Add 2 dies
    Add 3 dies

    Note: If you activated the tempest caller, you may want to keep all 3 interrupted until its over to prevent any instant deaths.

    [Heroic] You will take 100% more damage from each cast that is successful for 6 seconds, meaning you want to delay this by a minimum of 6 seconds.

    Void Stone

    The boss who activated this will receive an Umbral Shell

    This puts an absorb shield on the boss which needs to be broken, as whilst this absorb shield is active the raid will receive a debuff called Embrace of the Void. This debuff will reduce all healing received by 100%.

    Trident of Deep Ocean

    The boss who activated this will spawn a Custody of the Deep shield around itself. This shield will then last for 20 seconds and channel Abyssal Collapse.

    Any enemies within this shield will have 75% of their damage taken redirected into the shield, and when the Abyssal Collapse cast is finished any remaining value in the shield will be dealt to the raid in Frost damage.

    You will be able to see the shield amount and time remaining within the boss frames.

    Tempest Caller

    When this relic is activated Storm of Annihilation will be cast.

    Over the next 15 seconds there will be pulsing Nature damage going out to the raid.

    If any player goes below 25% health they will have Annihilate cast on them instantly killing them.

    Mythic

    Please note: There was no Mythic testing for this boss, so this is from the Dungeon Journal

    Agent of Demise healing reduction increased to 100% (up from 75%)

    Eldritch Abominations gain a new buff - Incomplete Form - This will make them immune to interrupts after 2 minutes.

    Witness the end increases the amount of damage taken from the casts by 500% for 12 seconds (up from 100% for 6 seconds from Heroic)

    Each of the relics will create an essence of itself which will persist until they are activated again.

    Void Stone - A Void Essence will be created and pull players towards it for 10 seconds. Every 40 seconds it will respawn increasing the power of the pulling effect.

    Trident of the Deep Ocean - The Trident will spawn an Oceanic Essence every 6 seconds. If a player makes contact with an Oceanic Essence they will be stunned for 8 seconds.

    Tempest Caller - A Storm Essence will spawn every 20 seconds. These will deal damage to the nearest player every 2 seconds and this damage will stack if the same player is hit multiple times. If this hits a target below 25% health they will be killed instantly by Annihilate.

    Tanking Notes

    Swap when your Shear Mind stack drops (this should be ~2/3 stacks per tank)

    Avoid your ranged tank.

    Void Stone - DPS down the Umbral Shell on the active boss. Utilise defensives here as healing received is reduced by 100%.

    Trident of the Deep Ocean - Put bosses/adds in the shield and AoE as much as possible.

    Tempest Caller - Stay above 25% health

    Class Tips/Tricks

    Vengeance Demon Hunter

    Sigil of Silence will apply its blanket silence to the Eldritch Abomination
