Single-phase encounter with two bosses that you fight simultaneously. They do not share a health pool. They alternate control over “The Hivemind,” changing how some mechanics need to be handled. Oh, there’s also a lot of bugs in this fight, a massive amount of bugs. We’ll discuss the Hivemind mechanics separately. All mechanics listed specifically under the individual bosses occur regardless of who’s controlling the Hivemind.
The Hivemind
Tek’ris control 0:00-1:11, 2:24-3:30, 4:44-5:51, 7:04-8:10
When the bosses are more than 20 yards away, they and all adds take 99% reduced damage
All adds gain 1% damage dealt and 1% movement speed every second they’re alive, stacking
Ka’zir control – 1:11-2:24, 3:30-4:44, 5:51-7:04, 8:10-9:24
When the bosses are closer than 20 yards, they and all adds take 99% reduced damage
When adds are below 20% HP, they heal for 3% health per second
When control of the Hivemind swaps, Devouring Frenzy occurs
Deals 10k Nature damage to the raid every 0.5 seconds for 12 seconds
Damage dealt increased by 15% each swap
Tek’ris
Nullification Blast
Frontal cone ability with a targeting reticle on the ground. Dodgeable
Deals 117k Shadow damage to anyone hit, and applies Nullification debuff
53k Shadow damage every 2s for 6s, and reduces healing received by 100%
Roll in a straight line in whatever direction they start in
Being hit deals 178k Nature damage and applies Corrosion
Corrosion deals 21k Nature every 2s and increases damage taken by 25% for 8s
Mind-Numbing Nova
Applies Mind-Numbing Toxin to the raid for 8s
Deals 36k nature damage every 2s and reduces Haste by 50%
This is interruptible.
Dark Reconstitution
When either boss reaches 1% HP, they become immune to damage and cast Dark Reconstitution, 12 second cast
If the cast completes, heals 50% of their max HP
If the second boss reaches 1% HP while the other is casting, they both die
Bug adds
Aqir Drone
Spawn at 0:35, 1:51, 3:40, 5:15, 6:32
Fixates on random targets
Leave puddles of acid when they die called Acidic Blood
Puddles deal 78k Nature damage every 1.5s when standing in it
Puddles despawn when the next set of Drones spawns
Aqir Darter
Spawn at 2:04, 2:42, 4:17, 6:45
Psionic Resonance
Deals 28k Shadow damage to the raid, then flies to a new spot in the room
Both types of adds spawn in groups.
Drones can be slowed and gripped
Strategy
On heroic, this boss is pretty straightforward. Dodge bad, kill priority adds.
Lust on pull
During Tek’ris’s Hivemind, tank the bosses together. During Ka’zir’s, tank them 22-25 yards apart
There is no tank swap mechanic on this fight
You start on Tek’ris’s Hivemind
Dodge the bowling ball bugs, don’t stand in the little green Acidic Blood puddles, and don’t get hit by Nullification Blast.
It’s dodgeable even by the tank it’s targeted at
Make sure to be spread 4-6 yards from everyone else during Echoing Void, so you don’t take the extra portion of damage
Use grips, knockbacks, etc to keep the Drones stacked on a boss to make cleave more effective
Hardswap the Ravager add, as they can get out of hand with damage on the tank fairly quickly. This is especially important during Tek’ris control
Also hardswap the Drone casting Volatile Eruption. It grows to about 3x the normal size and sticks out like a sore thumb. Killing it gives your healers a nice break
Interrupt the Mind-Numbing Nova
Use a raid healing CD for as many of the Echoing Voids as you can
Prioritize the ones at 1:20 and 6:00. These have overlaps with the Acidic Aqir bowling ball adds AND the Hivemind swap AoE effect. The combination of the raid-wide damage plus people getting hit by the bowling ball adds can be lethal
At 2:45 and 7:25, you have overlaps of Echoing Voids and the Bowling Ball adds, but without the Hivemind swap AoE. You will probably want CDs here too, but not as critical.
This fight isn’t really strategy-difficult. Rather, it’s personal responsibility difficult. It’s very easy to kill yourself on this fight during the bowling ball bugs, especially when paired with anything else going on.
Most of your wipes will simply be people learning and understanding how to effectively deal with the bowling ball bug mechanic. Once people figure it out, the boss falls fairly easily
Positioning
