The Xhul'horac encounter is a complicated, multi-phase fight that requires extremely high raid awareness and frequent target-swapping to destroy high-priority, low-health adds. The general flow of the fight is:
  • 100%-65% health: Xhul'horac wields Fel power, dealing Fire damage, and summoning a powerful Vanguard Akkelion along with Wild Pyromaniacs
  • 65%-35% health: Xhul'horac wields Void power, dealing Shadow damage, and summoning a powerful demon Omnus along with Unstable Voidfiends; Wild Pyromaniacs also still spawn
  • 35%-20% health: Xhul'horac phases quickly between Fel and Void powers, and continues to summon Unstable Voidfiends and Wild Pyromaniacs
  • <20% health: Xhul'horac is affected by Overwhelming Chaos and continues to phase quickly between Fel and Void Powers, but no longer summons any adds

Unleashed Energies

Throughout the fight, Xhul'horac swaps frequently between dealing Fire and Shadow damage. These two magics are at odds with one another, and players who take damage from both schools of magic in quick succession will cause powerful explosions. Players must avoid this by monitoring their debuffs and dodging as much avoidable damage as possible.

  • When a player takes Fire damage from any source, they gain a Feltouched debuff for 15 seconds
  • When a player takes Shadow damage from any source, they gain a Voidtouched debuff for 15 seconds
  • If a player with an active Feltouched debuff takes Shadow damage from any source, they will trigger a Shadowfel Annihilation
  • If a player with an active Voidtouched debuff takes Fire damage from any source, they will trigger a Shadowfel Annihilation
Shadowfel Annihilation deals heavy Shadowflame damage to all players within 20 yards of the triggering player, and light damage to players outside that radius.
  • Players triggering a Shadowfel Annihilation gain a Shadowfel Annihilation debuff, taking 50% more damage from subsequent Shadowfel Annihilations
  • All other debuffs ( Voidtouched, Feltouched, etc.) are removed when a player triggers Shadowfel Annihilation
  • Shadowfel Annihilation damage does not cause other players debuffed by Voidtouched or Feltouched to trigger additional Shadowfel Annihilations
Many of the abilities players will deal with during this encounter leave patches of flames on the ground.
  • Several of the Fel abilities leave Chaotic Felblaze patches
  • Several of the Void abilities leave Creeping Void patches
  • Players entering a Chaotic Felblaze patch will take damage from Felsinged, and gain Feltouched
  • Players entering a Creeping Void patch will take damage from Wasting Void, and gain Voidtouched
  • Chaotic Felblaze and Creeping Void spread over time to cover a larger area
  • If Chaotic Felblaze and Creeping Void touch, a Shadowfel Annihilation will occur at their location

Shadowfel Annihilation will remove all patches of Chaotic Felblaze and Creeping Void within 20 yards. As the encounter area fills up with these flames, players can strategically cause Shadowfel Annihilations to clear out space. This - along with avoiding accidental Shadowfel Annihilations - is a central mechanic of the encounter.

Phase 1: The Legion's Flame

Xhul'horac begins the encounter empowered by Fel energies, as denoted by the Fel coloration of his wings and body. While empowered by Fel energies, Xhul'horac attacks the tank with Fel Strike, dealing heavy Fire damage and inflicting Feltouched on the tank.

When Xhul'horac reaches 95% health, he will begin to drain energy from the nearby Fel Portal, gaining Fel Surge.

  • Xhul'horac targets several random, non-tank players with Fel Surge every 30 seconds
  • Fel Surge deals light Fire damage to the affected players every second for 5 seconds
  • When Fel Surge expires, a patch of Chaotic Felblaze is created at the player's position
  • Players affected by Fel Surge should run out of the raid to drop the Chaotic Felblaze near the edge of the encounter area
As long as the Fel Portal is open, Wild Pyromaniacs will periodically emerge to defend Xhul'horac.
  • Wild Pyromaniacs repeatedly cast Fel Orb at random players
  • The Fel Orb travels in a straight line, and disappears when its path is intercepted by any player
  • Intercepting a Fel Orb debuffs the player with Ablaze, a very strong, stacking Fire DoT effect
  • Fel Orb is interruptible, and Wild Pyromaniacs are stunnable
  • Players should aim to stun or interrupt every Wild Pyromaniac cast, and kill the imps quickly while they are incapable of casting

When Xhul'horac reaches 90% health, he will summon Vanguard Akkelion to aid him.

  • Vanguard Akkelion must be tanked, and will periodically attack the tank with Felblaze Flurry, dealing increasing Fire damage
  • The Vanguard will also cast Chains of Fel approximately every 35 seconds
  • Chains of Fel targets a random player and chains them to their two nearest allies
  • Chains of Fel deals periodic damage, increased by the number of other players you are chained to
  • To break the Chains of Fel effect, affected players must run far apart from one another

Damage dealt to Vanguard Akkelion will be copied to Xhul'horac, and damage dealt to Xhul'horac will be copied to Vanguard Akkelion. Because Vanguard Akkelion has a health pool equal to 25% of Xhul'horac's health pool, players will kill Vanguard Akkelion and end the Fel phase with Xhul'horac at 65% health.

Phase 2: Grasp of the Void

As soon as Vanguard Akkelion dies, Xhul'horac enters Phase 2, and begins to drain power from the Void Portal. While empowered by Void energies, Xhul'horac attacks the tank with Void Strike, dealing heavy Shadow damage and inflicting Voidtouched on the tank.

Xhul'horac also gains the ability to cast Void Surge once he draws power from the Void Portal.

  • Xhul'horac will target the furthest away player not currently affected by Feltouched for Void Surge, approximately every 30 seconds
  • Void Surge deals moderate Shadow damage to the affected player every second for 5 seconds
  • When Void Surge expires, a patch of Creeping Void is created at the player's position
  • The player targeted by Void Surge should run out of the raid to drop the Creeping Void near the edge of the encounter area
As long as the Void Portal is open, Unstable Voidfiends will periodically emerge to defend Xhul'horac.
  • Unstable Voidfiends spawn in random locations, but usually nearby a player
  • The Voidfiend targets the nearest player and begins to cast Volatile Voidstep, forming a purple swirl at the targeted player's feet
  • At the end of the Volatile Voidstep cast, the Voidfiend will teleport to the indicated location
  • If any players remain within the purple swirl as the Voidfiend teleports there, they will take moderate Shadow damage from Volatile Voidstep
  • Players should move just outside of the purple swirls each time they appear
  • Unstable Voidfiends cannot be stunned or interrupted, and should be killed quickly to reduce player movement

When Xhul'horac reaches 60% health, he will summon Omnus to aid him.

  • Omnus must be tanked, and will periodically channel Withering Gazeat the tank, dealing increasing Shadow damage
  • Omnus will also summon a Black Hole approximately every 30 seconds
  • The Black Hole will deal moderate Physical damage to the entire raid every second it exists, and will draw players toward its position
  • The Black Hole will collapse in a Singularity whenever any player(s) enter its boundary
  • Singularity deals heavy Shadow damage, split between all players within 11 yards of the triggering player
  • Players with strong personal cooldowns should be assigned to collapsing the Black Holes, and other players should stay more than 11 yards away when this occurs
  • Healers should use raid cooldowns to heal through Black Hole/ Singularity damage

Damage dealt to Omnus will be copied to Xhul'horac, and damage dealt to Xhul'horac will be copied to Omnus. Because Omnus has a health pool equal to 25% of Xhul'horac's health pool, players will kill Omnus and end the Void phase with Xhul'horac at 35% health.

Note that, since the Fel Portal is still open during this phase, Wild Pyromaniacs will continue to spawn, and players must continue to stun, interrupt, and kill them quickly to avoid Fel Orb damage.

As Phase 3 approaches, players with Voidtouched debuffs may wish to run toward the middle of the encounter area and clear out the Chaotic Felblaze patches by triggering Shadowfel Annihilations. These players should be sure to have a defensive cooldown available when doing so, and should alert the raid so that other players know to stay clear of the Shadowfel Annihilation explosion.

Phase 3: The Shadowfel Amalgamation

Once Omnus has died, Xhul'horac begins to switch rapidly between Fel and Void powers, using abilities from Phase 1 and Phase 2 in rapid succession.

  • Xhul'horac will flicker from green to purple to indicate which of these schools he is currently empowered by
  • He will attack tanks with alternating casts of Fel Strike and Void Strike, approximately 7 seconds apart
  • One tank must take every Fel Strike, while the other tank takes every Void Strike, to avoid triggering Shadowfel Annihilation
  • Xhul'horac will also alternate between casting Fel Surge debuffs and the Void Surge debuff
  • Players affected by these debuffs must continue to run out of the raid to form their Chaotic Felblazeor Creeping Void patches
  • Note that players can strategically place these patches to create Shadowfel Annihilations and clear additional space for the raid to move into

During this phase, both the Void and the Fel Portals remain open, so Wild Pyromaniacs and Unstable Voidfiends will continue to spawn. Players must still prioritize these adds over the boss.

Phase 4: Tearing Apart

When Xhul'horac reaches 20% health, he will fully absorb the energy of the Fel and Void Portals, closing them. No more Wild Pyromaniacs or Unstable Voidfiends will spawn for the remainder of the encounter.

During this phase, Xhul'horac continues to swap frantically between Void and Fel abilities, just as in Phase 3. Tanks must continue to swap for Fel Strike or Void Strike, and players must continue to run out of the raid with Fel Surge or Void Surge.

However, Xhul'horac becomes destabilized by the full power of both portals, and gains Overwhelming Chaos.

  • Xhul'horac will erupt with heavy Chaos damage every 10 seconds for the remainder of the fight
  • Each time he does so, he will gain a stack of Overwhelming Chaos, increasing the damage he deals by 10% per stack
  • This mechanic acts as a soft enrage; players must defeat Xhul'horac before his abilities become fatal
Players should avoid triggering Shadowfel Annihilations during this phase unless it is absolutely necessary, as a Shadowfel Annihilation in close succession to a pulse of Overwhelming Chaos may wipe the raid.

The raid should use Bloodlust/ Heroism/ Time Warp during this phase.
