To make it easy to navigate the guide, we have split it into 4 pages:

2. Lore

Il'gynoth is one of the first bosses in the Emerald Nightmare Raid Instance.

Lodged in the hollows of a now-decrepit world tree, Il'gynoth is a manifestation of the horrors that lie at the hear of the Nightmare. It is a mass of corruption - a thing that should not be. It's tendrils seep through the ground, emerging in countless horrifying eyestalks and limbs.

3. Outline

The fight against Il'gynoth consists in two Phases (One and Two) that repeat twice. In Phase One, you need to kill a stationary add called the Eye of Il'gynoth (by killing other adds next to it). Killing this add allows you to enter the chamber behind it where you can attack Il'gynoth for 50 seconds (this is Phase Two). If Il'gynoth is not dead after 50 seconds, then Phase One starts again and after successfully completing it, you get a second and last chance at finishing off Il'gynoth (if you do not manage, the raid wipes at the end of that second Phase Two).

Here is a preview of the fight from the Legion Alpha/Beta.


Below is a TL;DR of how to handle Il'gynoth's abilities, this should be used to familiarize yourself with the boss' abilities, and not as a blueprint for success (except maybe in LFR difficulty).

4.1. Tanks

4.2. Healers

  • Dispel Touch of Corruption Icon Touch of Corruption from raid members fixated by Nightmare Ichors.
  • Beware of tank damage from Nightmarish Fury Icon Nightmarish Fury (Dominator Tentacles) and Eye of Fate Icon Eye of Fate (Nightmare Horror).
  • Beware of massive AoE damage to raid members fixated by Nightmare Ichors if a large number of these adds are killed at the same time.

4.3. DPS

4.4. Everyone

  • Phase One
  • Phase Two
    • Keep players outside to finish off Tentacles and Nightmare Ichors.
    • Do as much damage as possible to Il'gynoth during Phase Two.
    • Make sure to move away 11 yards from other players when targeted with Cursed Blood Icon Cursed Blood during Phase Two.
    • Get out of the chamber before the 50 seconds are up (so before Dark Reconstitution Icon Dark Reconstitution finishes casting).

5. ChangeLog

  • 04 Oct. 2016: Added a small note regarding killing Corruptor Tentacles with priority if the Deathglare ones are properly interrupted.
