Xavius Strategy/Tactics for Normal/Heroic
Table of Contents
General Information
On this page, you will find a working strategy to defeat Xavius in The Emerald Nightmare for both Normal and Heroic modes, which usually only differ by the tuning of the boss.
Here, we assume that you have read our descriptions of the abilities for this encounter.

Overview
The fight against Xavius is made up of 2 phases during which you learn the fight and the abilities before having to burst down Xavius in the last phase, where he uses a mix of his Phase One and Phase Two abilities.
The key to the fight is Corruption management, which requires players in the dream
(with the Dream Simulacrum debuff) to try and be the ones who receive the Corruption
that cannot be avoided. Since this is the most important aspect of the fight, this is what
we will start with. Remember to never let your Corruption reach 100, even if you are in
the dream).
Then, we will speak a bit about positioning and what the different roles have to do. We will not split the explanations according to each phase. We will not split the strategy in Phase One, Phase Two, and Phase Three sections as these are too similar to one another.
Managing Corruption
The one thing to keep in mind is that not all of Xavius' abilities give
Corruption. Many do not and most players (DPS players in particular) should
reach Phase Three with very little Corruption, especially with the chance of
resetting it when you exit the dream (so when you die with
Dream Simulacrum or when you let that debuff expire).
Since it is so crucial that players within the dream (with the
Dream Simulacrum debuff) be the ones handling abilities that increase
Corruption, we feel that it is important to remind you of what these abilities
are and who exactly gets Corruption from them.
- Phase One
- The healer dispelling
Darkening Soul gains 25 Corruption (happens every 30 seconds if the raid decides to dispel at 3 stacks).
- The tank picking up the Corruption Horror takes 5 Corruption for every cast
of
Corrupting Nova (every 20 seconds) and for every cast of
Tormenting Swipe (every 10 seconds).
- the player intercepting the Lurking Terror takes 20 Corruption in Normal mode and 30 Corruption in Heroic mode (happens every 20 seconds).
- The healer dispelling
- Phase Two
- The healer dispelling
Blackening Soul gains 25 Corruption (happens every 30 seconds if the raid decides to dispel at 3 stacks).
- Soaking
Corruption Meteor gives 40 Corruption divided by the number of players soaking, every 30 seconds.
Nightmare Infusion gives 30 Corruption to the tank (6 times 5 Corruption).
Dark Ruination gives 1 Corruption per second to every raid member, but it should never be allowed to be applied on Xavius.
- Soaking
Tainted Discharge gives about 10 Corruption and needs to be repeated between 15 and 30 times, depending on raid size and time spent in Phase Two.
- The healer dispelling
- Phase Three
Blackening Soul,
Corruption Meteor, and
Nightmare Infusion are the same as in Phase Two.
- Every cast of
Nightmare Bolt gives 3 Corruption to a random raid member (5 in Heroic mode). This can ramp up pretty quickly, depending on whether or not you decide to ignore the Nightmare Tentacles to burn down the boss.
- All Phases: Once you are above 66 Corruption, you will likely reach
100 pretty quickly, because you will have to avoid all of the
Corruption: Unfathomable Reality in addition to everything else the encounter throws at you.
Simply listing the sources of Corruption gives a pretty good overview of the important tasks:
killing the Corruption Horrors and Inconceivable Horrors very quickly,
dispelling Darkening Soul and
Blackening Soul, properly
soaking
Meteor, and choosing the right people to soak
Tainted Discharge
pools.
Positioning
In Phase One, you want the raid to be loosely spread out 6 yards for
Lurking Eruption. It should be much more than this, because you want
the tanks to be able to easily move out for the dispel of their
Darkening Soul. For
Nightmare Blades, we suggest to leave a
line between the melee and ranged groups where the debuffed players can go.
Finally, melee players should avoid coming close to the
Corruption Horrors.
In Phase Two, Lurking Eruption and
Nightmare Blades
disappear, so the entire raid can loosely stack behind the boss. This helps
with dealing with
Corruption Meteor and
Bonds of Terror, but can
make it harder to notice
Corruption: Crushing Shadows and
Corruption: Unfathomable Reality.
In Phase Three, Nightmare Blades makes a return, so you can reuse
the empty line positioning.
Tanks
Tanks need to alternate being debuffed with Darkening Soul in Phase
One and
Blackening Soul in Phase Two and Three. We found that
dispelling at 3 stacks works well, acting as a good compromise between taking
increasing damage from the increased stacks and not dispelling too often. Also,
in Phase Two, 30 seconds allows for
Blackened to drop before
re-tanking the boss. It is important the tank move out of range of raid members
before getting the debuff dispelled.
When a Corruption Horror spawns in Phase One, it should be picked up by the tank in the dream, preferably. This add needs to be tanked away from the raid and it must not be facing anyone else but its tank.
When Xavius buffs himself with Nightmare Infusion in Phase Two and Three,
it is preferable that he be tanked by the tank in the dream (although there may no longer
be a tank in the dream by Phase Three).
Healers
Healers in the dream, preferably, need to dispel Darkening Soul and
Blackening Soul from the tanks. It is important to wait for the tank to
be out of range of the raid members before dispelling and to make sure they have at
least 3 stacks.
Beware of failed Corruption Meteors (not enough people stacking),
Dark Ruination (when the DPS do not kill the Inconceivable Horrors fast
enough), and
Nightmare Blades (blades in the raid).
DPS
DPS down Corruption Horrors (Phase One) and Inconceivable Horrors (Phase Two) as fast as possible.
DPS in the dream (preferably) need to intercept Lurking Terrors
(Phase One) and soak Tainted Discharge pools of corruption (Phase
Two).
In Phase Three, nuking the boss or the Nightmare Tentacles will be at the discretion of the raid leaders, as mentioned a few sections below.
Everyone
- Spread out 6 yards in Phase One for
Lurking Eruption.
- Make sure that
Nightmare Blades (Phase One and Three) is dropped in a safe location, typically in a line separating the melee and the ranged players.
- Move in to soak
Corruption Meteor, unless your Corruption is much higher than the rest of the raid.
- When targeted by
Bonds of Terror (Phase Two / Heroic mode), simply move close to the other targeted player.
- Avoid being hit by
Corruption: Crushing Shadows when you are over 33 Corruption and
Corruption: Unfathomable Reality when you are over 66.
- Do not ever get to 100 Corruption.
Phase Three Burn
The raid should keep potions and DPS/healing cooldowns for Phase Three and proceed in one of two ways, depending on encounter tuning.
- Nuke the boss, in which case, DPS cooldowns are activated right away.
- DPS the Nightmare Tentacles and direct spare DPS towards the boss. DPS Cooldowns can be used at the beginning of the phase or later up, if it becomes hard to keep up with the tentacles.
We currently do not know which way is the best. On beta, nuking the boss was definitely the way to go on Normal mode. Phase Three in Heroic mode was seen by very few people (if any), so it is hard to conjecture.
