Initially, players must defeat Fel Iron Summoners and the demons they call forth from the Fel Spires

Once the Fel Iron Summoners are dead, Gul'dan will destroy a Fel Spire and use its power to resurrect a weakened Mannoroth

When the weakened Mannoroth reaches 65% health, Gul'dan will destroy a second Fel Spire and use its power to restore Mannoroth to his full strength

When Mannoroth reaches 35% health, Gul'dan destroys the final Fel Spire and uses its power to grant Mannoroth unspeakable power

Phase 1: The Legion's MightBlood of MannorothBlood of Mannoroth

The Fel Iron Summoner in front of the red Fel Spire is powering a portal that summons Doom Lords

The Fel Iron Summoner in front of the purple Fel Spire is powering a portal that summons Fel Imps

The Fel Iron Summoner in front of the green Fel Spire is powering a portal that summons Dread Infernals

Curse of the Legion

Doom Lords must be tanked, and will stack Doom Strike on their melee target

Doom Strike deals no damage on application, but when it expires, it will deal damage based on the number of stacks present

The tank should use a cooldown to mitigate the Doom Strike damage

Shadow Bolt VolleyMark of Doom

Shadow Bolt Volley will deal moderate damage to all players, but can be interrupted

Mark of Doom chooses several targets at random; these targets will become Doomed after 15 seconds, taking fatal damage

If a player with the Mark of Doom takes damage from any source before the debuff expires, Mark of Doom is removed, and the player instead triggers a Mark Eruption

The Mark Eruption deals moderate damage to all players within 20 yards of the Mark of Doom target

When affected by Mark of Doom, players should run away from the raid and each other, and purposefully take damage to trigger the Mark Eruption when no other players are within its radius

Use Blood of Mannoroth damage to trigger Mark Eruption, by standing in the pool in the center of the room

Inferno

Dread Infernals will channel a long Fel Hellfire cast, dealing periodic Fire damage to players within 10 yards

At the end of this cast, Dread Infernals will cast Fel Streak, and rush to a random location

Players within 8 yards of that location will take heavy Fire damage when the Dread Infernal lands

Melee DPS cannot easily attack Dread Infernals, so ranged DPS should be in charge of killing them

Fel Imp-losionFel Imp-losion

Fel Imp-losion deals light Fire damage to players within its 3-yard radius as the Fel Imps spawn

Fel Imps will repeatedly cast Fel Blast, which targets random players and deals moderate Fire damage to all players within 3 yards of the target

When a Fel Imp's mana bar fills up, it will cast Phase Blink, teleporting to a random location

Fel Imps can be stunned and interrupted, and are susceptible to knockback and other forced-movement abilities

Players should use CC and interrupts to prevent Fel Blast casts, and burn the Fel Imps down quickly

Return to Table of ContentsPhase 2: The ResurrectionFel Imps and Dread Infernals will continue to spawnGlaive Combo

The Glaive Combo consists of a Glaive Thrust, a Massive Blast, and then a second Glaive Thrust

These attacks happen 1.5 seconds apart, and a Glaive Combo will occur every 30 seconds

Glaive Thrust deals very heavy damage to the current tank, and will inflict a Puncture Wound if the tank does not have an Active Mitigation ability up

Massive Blast will knock the current tank back, dealing heavy Shadow damage, and debuffing them so the next Massive Blast within 45 seconds will deal 300% increased damage

One tank should take the first Glaive Thrust and the Massive Blast; the second tank should taunt and take the second Glaive Thrust

The Massive Blast knock-back is huge, so tanks should position themselves with their backs against a Fel Spire to avoid being knocked off the platform

Healers will need to focus healing on the tanks for the Glaive Combo, and may be asked to provide external CDs for the tanks

Fel Hellstorm

Fel Hellstorm's fireballs will fall every 0.5 seconds for 3 seconds, and their location is telegraphed by dark black circles

Players within 6 yards of a Fel Hellstorm impact will take heavy Fire damage

Players should move out of the Fel Hellstorm indicators quickly to reduce the amount of raid damage taken

This mechanic is likely to deal moderate raid damage; healers can consider using raid cooldowns to heal through it

Felseeker

Initially, Felseeker will deal moderate damage to players within 10 yards of its location

The second pulse of Felseeker deals heavier damage to players within 20 yards of its location

The third pulse of Felseeker deals heavy damage to players within 30 yards of its location

Players must react quickly to move out of the telegraphed Felseeker radius before taking damage

Movement speed-increasing effects like Stampeding Roar are useful for helping the raid avoid the final, highly damaging pulse of Felseeker

Mannoroth's Gaze

Mannoroth's Gaze selects three players at random and Horrifies them, causing them to run mindlessly for 4 seconds

When this effect is removed or expires, Mannoroth's Gaze deals heavy damage to its target, split by all players within 8 yards

One or two additional players to soak each Mannoroth's Gaze should be sufficient, especially if the soakers have personal cooldowns to use

As this is a Shadow-school Horrify effect, it cannot be removed by dispels, Mass Dispel, or Tremor Totem, and it cannot be prevented by Fear Ward

However, immunities that can be used to remove debuffs, such as Divine Shield and Cloak of Shadows, can remove the Mannoroth's Gaze debuff

Note that doing so will instantly inflict the Mannoroth's Gaze damage

Other immunities will break the player free from the Horrify effect, but the Mannoroth's Gaze damage will still occur at the end of the debuff

Mannoroth chooses three random players and afflicts them with Shadowforce, repelling the players away from him

The speed at which players are pushed away from Mannoroth will increase over time

The affected players must push back against the Shadowforce by running forward, and can steer themselves with strafe keys, to avoid being pushed off the platform

When Shadowforce expires, the affected players are briefly buffed with Lingering Forces, gaining 300% movement speed for 1.5 seconds

Players should use this to return to combat range with Mannoroth, but be careful not to run off the platform!

ShadowforceReturn to Table of ContentsPhase 4: EMPOWERMENT!Massive Blast

Empowered Glaive Combo causes both Glaive Thrust and Massive Blast to deal additional damage and have additional properties

Empowered Glaive Thrust will deal its damage to all players in front of the boss, so the second tank should step aside

Empowered Massive Blast will knock the tank back a long distance, so the tanks must position themselves to be knocked back along the central axis of the platform

Additionally, Empowered Massive Blast will create three Empowered Massive Blast Wave projectiles that will deal heavy damage to players in their path

Non-tanks must not move in front of Mannoroth during Empowered Glaive Combo

Empowered Fel HellstormEmpowered Fel HellstormEmpowered FelseekerFelseekerEmpowered FelseekerEmpowered ShadowforceEmpowered Mannoroth's GazeGazing ShadowsGazing ShadowsEmpowered Mannoroth's Gaze

Gazing Shadows deals moderate periodic Shadow damage to players in its area of effect, and reduces movement speed by 50%

The size of the Gazing Shadows patches depends on the number of players who helped to soak the damage when Empowered Mannoroth's Gaze expired

More players soaking creates a larger Gazing Shadows; 4+ players in a single Empowered Mannoroth's Gaze can create a Gazing Shadows large enough to cover nearly half the platform

Just before Empowered Mannoroth's Gaze is cast, players should spread out slightly so that the three targets are less likely to all run in the same direction and all count toward each other's Gazing Shadows

The Fel Iron Summoner at the red Fel Spire

The Fel Iron Summoner at the green Fel Spire

The Fel Iron Summoner at the purple Fel Spire

Tanks can put their backs to the Fel Spire so that the pillar will catch them during Massive Blast

During Phases 2 and 3, killing adds takes priority over DPSing Mannoroth

The raid should stack tightly on one of Mannoroth's back legs, to bait Fel Imps and Infernals closer together

This will also mean that the players affected by Mannoroth's Gaze are likely to run in the same direction, allowing for easy soaking of the damage effect

The raid should assign a few players to help soak Mannoroth's Gaze and Empowered Mannoroth's Gaze, preferably players with strong mobility and damage-reduction cooldowns

Players can either regroup on the same leg after each Felseeker, or, swap to the opposite side of Mannoroth each time Felseeker is cast

When Phase 4 begins, the green Fel Spire will be destroyed, so tanks must face Mannoroth toward the center of the platform

Players must avoid being in front of Mannoroth unless they are tanking, or during Empowered Shadowforce while Mannoroth does not use his Empowered Glaive Combo abilities

The raid should spread out slightly for Empowered Mannoroth's Gaze, so that the affected players do not all run on top of each other, dealing heavy damage to each other and creating large Gazing Shadows pools

Use Bloodlust/Heroism/Time Warp during this phase to defeat Mannoroth quickly

Return to Table of ContentsTank Responsibilities

During Phase 1, the only enemy to tank is the Doom Lord summoned by the first Fel Iron Summoner

At the start of Phase 2, pull Mannoroth toward the green Fel Spire and place your back to it

Each time Mannoroth begins his Glaive Combo, one tank should take the first Glaive Thrust and the subsequent Massive Blast, while the other tank taunts for the second Glaive Thrust

Use Active Mitigation abilities during the Glaive Thrust cast to avoid taking a Puncture Wound

The Massive Blast debuff means no tank can take two Massive Blasts in a row; the tank who takes the final Glaive Thrust of one Glaive Combo must take the first Glaive Thrust & the Massive Blast of the next Glaive Combo

When Phase 4 begins, spin Mannoroth around so he is on the edge and Empowered Massive Blast will knock you across the platform safely

During Phase 4, tanks should not both stand in front of Mannoroth, as Empowered Glaive Thrust will deal its damage to all players in front of the boss

If necessary, after an Empowered Mannoroth's Gaze creates Gazing Shadows pools, move Mannoroth a few yards along the outside edge of the platform to give the raid more space

Damage-Dealer Responsibilities

If affected by Curse of the Legion in Phase 1, run to the tank, use a cooldown, and call for a dispel

If affected by Mark of Doom in Phase 1, quickly move away from the raid, then intentionally take damage to clear the debuff

In Phases 2-3, adds take priority over Mannoroth; ranged DPS should prioritize Dread Infernals and melee DPS should prioritize Fel Imps

React quickly to each of the various ground-based AoE effects to avoid taking excessive damage

If targeted by Shadowforce, save movement speed-increasing abilities for late in the mechanic, when the pushback effect is the strongest

If assigned to soak Mannoroth's Gaze, follow the affected players as they run out of the raid

In Phase 4, spread out slightly as Mannoroth reaches 100 Energy to avoid too much overlap of Mannoroth's Gaze effects

In Phase 4, when Mannoroth uses Empowered Shadowforce, angle your facing or use strafe keys to control your direction, to avoid entering Gazing Shadows or falling off the edge of the platform

Healer Responsibilities

In Phase 1, players with Curse of the Legion or Mark of Doom will require spot healing

Dispel Curse of the Legion when called for

During Phases 2-4, tanks will take heavy damage from Glaive Combo; pre-cast shields or strong single-target heals on both tanks, and be prepared to use external CDs if called for

Raid damage will be heavy during Fel Hellstorm, Mannoroth's Gaze, Empowered Shadowforce, and Empowered Felseeker

If affected by Curse of the Legion in Phase 1, run to the tank, use a cooldown, and cdispel yourself

If affected by Mark of Doom in Phase 1, quickly move away from the raid, then intentionally take damage to clear the debuff

React quickly to each of the various ground-based AoE effects to avoid taking excessive damage

If targeted by Shadowforce, save movement speed-increasing abilities for late in the mechanic, when the pushback effect is the strongest

If assigned to soak Mannoroth's Gaze, follow the affected players as they run out of the raid

In Phase 4, spread out slightly as Mannoroth reaches 100 Energy to avoid too much overlap of Mannoroth's Gaze effects

In Phase 4, when Mannoroth uses Empowered Shadowforce, angle your facing or use strafe keys to control your direction, to avoid entering Gazing Shadows or falling off the edge of the platform

Doom Lords must be tanked, but even in Mythic mode one tank should hold the Doom Lord until it dies

The player targeted by Curse of the Legion should run close to tanks, use a survivability cooldown, and call for a dispel to spawn the Doom Lord

Doom Spike will deal heavier damage on Mythic mode, so tanks may wish to use a strong survivability CD when the debuff wears off

Additionally, when Doom Spike wears off, it deals Explosive Doom Spike damage to players within 30 yards

The tank affected by Doom Spike must run away from the raid before the debuff expires, to avoid splashing Explosive Doom Spike damage onto the raid

Mark of Doom

Players affected by Mark of Doom must run out of the raid to avoid splashing Mark Eruption on to other players

These players must intentionally take damage from a mechanic in order to remove the Mark of Doom

Players can ensure this happens by allowing the Doom Lord to cast Shadow Bolt Volley after the Mark of Doom players have spread out appropriately

Mark of DoomMark of DoomPhase BlinkPhase ExplosionPhase BlinkWrath of Gul'dan

Mannoroth will choose five random targets and debuff them with Wrath of Gul'dan

This debuff has 40 stacks, and every second it will attempt to apply Gripping Shadows to nearby targets

Each stack of Gripping Shadows that is applied will reduce the player's Wrath of Gul'dan stacks by 1

A maximum of 3 stacks can be leeched off each second in this way

There does appear to be a maximum range, beyond which Gripping Shadows will not pass to another player - players soaking Gripping Shadows must move close to the Wrath of Gul'dan target

Gripping Shadows deals a single pulse of Shadow damage and places a stacking Gripping Shadows debuff on the players it damages

The debuff increases subsequent Gripping Shadows damage by 25% for 15 seconds
