Il’gynoth is a two phase encounter. Phase one you fight Il’gynoth’s body, phase 2 you destroy organs. You will need to cycle through 3 times total to defeat his 3 organs and complete the encounter.
Phase 1
Eye of N’zoth
Beam shoots out from Il’gynoth’s chest, dealing 446k Shadow directly in front of him, and increases damage taken by subsequent Eye of N’zoth by 75%
Debuff lasts 43 seconds
Cast at 0:06 into each Phase 1, then every 18 seconds
Touch of the Corruptor
MC’s random players, and causes them to run around
If an MC’d player gets too close to another player, they will also become MC’d
Broken when the MC’d player reaches 30% HP
Corruptor’s Gaze
Standard Eye Beam type ability, cast at several random players
Starts as a swirlie, then turns into a beam
Beam chases the selected players for 5 seconds
The Beam leaves pools anywhere it went over, called Morass of Corruption
Standing in the pools deals 89k Shadow damage every second, and pacifies and silences you
Blood of Ny’alotha
During your second and third Phase 1, blood goop adds will spawn
These fixate on random targets and chase them
Each time you’re melee’d by one of these blood adds, you’ll gain a stack of Recurring Nightmare
Deals 18k Shadow damage every 2s for 40s
Stacks
Dispellable
When a blood add dies, it explodes and deals 86k Shadow to the entire raid
Spawn every 30s in your 2nd and 3rd Phase 1s
These are slowable, rootable, etc
When Il’gynoth’s HP reaches 0, you enter Phase 2
Phase 2
Cursed Blood
Infects 8 random players with a debuff, dealing 18k Shadow every 2s for 8s
When it ends, players explode for 143k Shadow to everyone within 11 yards
Organ of Corruption
3 Organs spawn around the room
Killing any Organ ends Phase 2, and moves you back to Phase 1
That Organ stays dead the rest of the fight
Blood of Ny’alotha
Created by living Organs in this phase, as a cast
Cast is interruptible
If one spawns, it has all the same abilities as listed above
Strategy
Phase 1
Tanks need to swap every 2 stacks of Eye of N’zoth
Nobody else should be standing near the tanks, and the tanks should be slightly spread so they don’t both get hit by the same Eye of N’zoth beam
You may find it helpful to have markers on your tanks, or a world marker down at the location tanks will be, to help people avoid being hit
Everyone else should be spread throughout the room
When Touch of the Corruptor goes out, hard swap to the MC’d people and break them ASAP
You do not want them reaching other players and spreading this, do everything you can to prevent it
If targeted by Corruptor’s Gaze, move away from the beam. Try to drop your puddles in a neat little circle near where you are. This’ll help reduce the area covered by puddles, and help prevent the puddles from blocking parts of the room. Here’s an example of a good goop drop:
In your 2nd and 3rd Phase 1s, the Blood adds become priority, behind only the MC’s.
These come from the location of the Organ/Organs you’ve killed up until that point
Slow them, root them, stun them, whatever
If you’re targeted, make sure you’re running away and don’t let the Blood reach you
If you do get melee’d by the Blood, call for a healer to dispel you
Once Il’gynoth’s HP reaches 0, you enter Phase 2
Phase 2
This phase lasts until you kill off an Organ. You may only kill off 1 per phase, so you’ll repeat this phase 3 times to defeat the encounter
Once you kill an Organ, Il’gynoth respawns with full HP and you enter a Phase 1 again
Have a set order to kill the Organs each time, so the raid moves together to the proper Organ
Organs cast Pumping Blood frequently to spawn Blood adds. Interrupt as many casts as possible
The first cast of Pumping Blood happens as soon as the adds become targetable
Subsequent casts occur every roughly 7 seconds
Assign ranged DPS to each Organ not being focused down to interrupt
Just get as many interrupts as you can. The more Bloods that spawn, the more dangerous this phase is
Players affected by Cursed Blood need to move away from the raid to prevent exploding on people
Priority for DPS in this phase is Slowing/CCing adds, then nuking Organs. You want to kill off your targeted Organ as fast as possible
When you re-enter Phase 1, clean up any Blood adds
After cycling through killing the 3 Organs, you’ll go into a 4th and final Phase 1
There’ll be a large amount of Blood adds, so we recommend using Bloodlust and raid healing CDs here
Positioning
Before you pull, put markers along the 3 passageways where the organs spawn:
During Phase 1, you should have the raid loosely spread around the room, except where the tanks are assigned to stand:
During Phase 2, just move towards whatever Organ you’re assigned to be killing.
