Adventure Guide Entry
The in-game Adventure Guide text for the Xavius encounter in The Emerald Nightmare.
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
- Players affected by Dream Simulacrum should protect non-dreaming players by handling any abilities that spread corruption.
- Move away from others when Darkening Soul and Blackening Soul is about to be dispelled from you.
- Quickly pick up Corruption Horrors when Manifest Corruption is cast.
- Absorb Tainted Discharge before it can reform back into Inconceivable Horrors.
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.
Corruption: Unfathomable Reality
Corruption: Descent into Madness
Stage One: The Descent Into Madness
Stage Two: From the Shadows
Upon reaching 65% health remaining, Xavius intensifies his attack.
Stage Three: World of Darkness
