The Emerald Nightmare in the Adventure Guide

Raid - Legion

The Emerald Nightmare

7 encounters, 140 boss abilities and 108 drops, with the Adventure Guide’s own ability and strategy notes for each fight. Every drop links to its item page; tradeable drops carry an Auction House price.

The Emerald Dream was created by the titans as a blueprint for Azeroth itself - a verdant and perfect mirror that reflects the state of nature had it remained unspoiled by so-called civilization. For many years, the druids and keepers who are closest to nature have noticed signs of an unsettling presence stirring within the Dream. Spurred on by the Legion and Nightmare Lord Xavius, that creeping corruption has now burst forth, and will engulf all of Azeroth if it is not rooted out at its source.

Ursoc

Ursoc is one of the Wild Gods. Patron of the furbolg, and closely linked to the druidic power of shapeshifting, the ancient great bear has long been a protector of Azeroth. But as Ursoc slumbered at his shrine in the Grizzly Hills, the world around him was plunged into corruption, and he awoke to torment and nightmare, consuming and twisting his being.

Abilities & Strategy

Overview

Ursoc tramples his enemies with Barreling Impact and periodically roars for a Roaring Cacophany. In Mythic difficulty, Nightmare Images periodically animate and attack players.

Nythendra

Nythendra was once a member of the Green Dragonflight charged with guarding the world tree, Shaladrassil. When Xavius' corruption of the Nightmare consumed Shaladrassil, it consumed the sleeping guardian as well. Nythendra is now nothing more than a skeletal version of herself, swarming in pestilence, ready to devour anyone or anything foolish enough to enter her lair.

Abilities & Strategy

Overview

Nythendra's Infested Breath unleashes great gouts of insects and corruption, consuming 50 Energy. When Nythendra's Energy is depleted, she collapses to the ground and Heart of the Swarm begins. Once she is fully recharged, her form coalesces and she resumes her attack.

Dragons of Nightmare

The Emerald Dream was entrusted to Ysera for safekeeping, and the mightiest of her green dragon brood were assigned to stand watch over four portals that connected directly to Azeroth. But even before the Cataclysm, these dragons began to show signs of corruption. Now, the path to the Nightmare's core runs through the dragons' lair.

Abilities & Strategy

Overview

Ysondre shares health with Emeriss, Lethon, and Taerar. She begins the fight alongside the nightmare of one of her former cohorts. When Ysondre reaches 70% health remaining, the nightmare takes to the skies and a new one emerges from a nearby portal. Upon reaching 40% health remaining, the nightmare dragon in the air lands and the one on the ground takes to the air. In Mythic difficulty, Ysondre is accompanied by Emeriss, Lethon, and Taerar at all times.

Damage Dealers
  • Be sure to switch targets to prevent Slumbering Nightmare from triggering.
  • Try not to stand directly behind the dragons so as to not be struck by Tail Lash.
  • Stand within the Nightmare Bloom to prevent Dread Horrors from spawning.

Xavius

Once a powerful mage, and a councilor to Queen Azshara, Xavius forged a pact with Sargeras to enable the Legion's first invasion of Azeroth. Cursed and tormented in the wake of that defeat, Xavius plots vengeance against the world from within the Rift of Aln. Those who venture into the Nightmare will face the full extent of his power, and his true form - a grotesque and distended monstrosity.

Abilities & Strategy

Overview

Most of Nightmare Lord Xavius's attacks inflict Corruption on their victims. As a player gains more Corruption, they become increasingly vulnerable to the power of the Nightmare, eventually losing control entirely and turning against their friends at maximum Corruption. Players' only hope lies in the power of Ysera, who puts many of them into a deep slumber and forms a Dream Simulacrum of those players. When their Simulacrum perishes, the affected player will awaken, as any Corruption gained by their Simulacrum dissipates harmlessly.

Damage Dealers
  • Players affected by Dream Simulacrum should protect non-dreaming players by handling any abilities that spread Corruption.
  • Defeat Inconceivable Horrors before they can get close enough to cast Dark Ruination on Xavius.
  • Absorb Tainted Discharge before it can reform back into Inconceivable Horrors.
Healers
  • Players affected by Dream Simulacrum should protect non-dreaming players by handling any abilities that spread corruption.
  • Dispel Darkening Soul and Blackening Soul as sparingly as possible to manage the amount of Corruption you gain.
  • Absorb Tainted Discharge before it can reform back into Inconceivable Horrors.
Tanks

The Dream

When Xavius reaches 95% and 60% health, the Dream of Ysera puts half of the party into a Dreaming State. Affected players fall asleep while a Dream Simulacrum of them rises to fight Xavius. If the Dream Simulacrum should ever die, the player's actual body will awaken. All Nightmare Corruption gained by the Dream Simulacrum is lost when the player returns to their body.

Nightmare Corruption

Many of Xavius's spells spread Nightmare Corruption to those hit. The more corrupted a player becomes, the more the nightmare becomes real to the player. Should any player ever become completely corrupted, they will become dominated by Xavius.

Dread Abomination

At 33 points of Corruption, colossal Nightmare creatures materialize from the player's mind, smashing the world around the player.

Il'gynoth, Heart of Corruption

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

Abilities & Strategy

Overview

Players begin the encounter fighting against Il'gynoth's erupting eyestalks and tentacles, while the monstrous Eye bars the way to the heart of the tree. Defeating these tentacles spawns animated Nightmare Ichor globules, which players can destroy near the Eye to damage it. Once the Eye is defeated, players can enter the hollow to damage Il'gynoth directly for a time, after which the Eye reforms to seal the entrance to the hollow once more, killing any players who remain inside. This repeats until players defeat Il'gynoth.

Damage Dealers
  • Move away from the raid when affected by Spew Corruption.
  • Interrupt Deathglare Tentacles' Mind Flay.
  • Lure Nightmare Ichors that are fixated on you to the Eye of Il'gynoth when they are low on health, and wait to kill them until they are in range of the Eye.
  • Avoid players targeted by Ground Slam, and move away from other players when targeted by it.

Stage One: The Ruined Ground

Players engage creatures of nightmare while the Eye of Il'gynoth watches over them, directing the forces of corruption.

Elerethe Renferal

Elerethe, once a mighty druid and adept shapeshifter, was led down a dark path by the belief that she was betrayed by her closest allies. Her consciousness now resides in the nightmare, damning her to an existence of fear, confusion, and hatred.

Abilities & Strategy

Overview

As the fight progresses, Elerethe swaps between the nightmarish forms of a spider and a roc. When she takes to the skies as a roc, she moves to a different platform, forcing players to weather her Dark Storm as they make their way towards her. On Mythic difficulty, Elrethe uses an additional ability depending on what platform she is currently on. On the first platform she uses Tangled Webs, on the second she uses Violent Winds, and on the third Nightmare Spawn.

Damage Dealers
  • During Spider form, stand apart from the raid during Necrotic Venom to place venomous pools.
  • During Roc form, place Twisting Shadows away from the raid.
  • Kill Venomous Spiderlings.
Healers
  • During Spider form, heal allies connected by Web of Pain.
  • During Roc form, the raid takes ramping damage from Dark Storm until they reach the eye of the storm.
Tanks
  • During Spider form, take turns tanking Spiderlings to manage applications of Dripping Fangs.
  • During Roc form, quickly taunt Elerethe after Raking Talons.
  • During Roc form, pick up a Shimmering Feather to speed your way across the webbing.
  • Keep Venomous Spiderlings away from the boss or they will grant her stacks of Swarm.

Cenarius

The demigod Cenarius is the father of druidism in Azeroth, and one of Azeroth's oldest and most powerful protectors. His disturbing slumber within the groves of Val'sharah was the first sign of the depth of the growing threat from within the Nightmare. That dark power now has complete hold over him, and he may lie beyond hope of redemption.

Abilities & Strategy

Overview

The fallen Cenarius periodically creates Nightmare Seeds, which germinate for a short duration and then summon an Ally of Nightmare that must be defeated. Malfurion aids in the battle and cleanses the Nightmare Seed with the largest number of nearby players, purifying that Ally so that it instead helps the raid.
