Mythic Mode Abilities
Phase One: The Betrayer
Shadow Reflection: Wailing is a new mechanic that is targeted on the current tank in the first 2 non-intermission phases. 7 seconds after being applied, a Wailing Reflection will spawn under the debuffed player. The Wailing Reflection will cast Sorrowful Wails, dealing moderate Shadow damage to players within 10 yards and applying a stack of Crescendo with each hit, which further amplifies successive hits.
After the Wailing Reflection is killed, it will apply the Lingering Wail debuff to the tank on which Shadow Reflection: Wailing was applied. This deals extremely heavy Shadow damage every 2 seconds until it is dispelled. When it is dispelled, it triggers Wailing Grasp, which grips all players to the current location of the tank.
Players affected by Shadow Reflection: Erupting will also spawn Erupting Orbs at their position. If any player is hit by an Erupting Orb it will trigger a Chaotic Eruption, inflicting heavy Shadow damage to anyone within 8 yards and knocking them into the air. The players spawning the orbs will also trigger a Latent Eruption automatically as the orbs begin to spawn, dealing heavy Shadow damage to anyone with 5 yards and knocking them back.
Rupturing Singularity's knockback is significantly farther in Mythic difficulty; this applies to all phases in which this mechanic is present. It also spawns in the corners of the room in all phases rather than the center.
Phase Two: Eternal Flame
Rupturing Singularities will spawn in rapid succession on Mythic difficulty, with each Singularity making impact only seconds after its predecessor.
Phase Three: Reflected Souls
Shadow Reflection: Hopeless is an additional reflection mechanic present following the first intermission phase. This debuff is exclusively applied to healers, and spawns a Hopeless Reflection 8 seconds after it is applied. This reflection is unique from the others, as it is a friendly unit, and must be healed.
Hopeless Reflections will, unsurprisingly, cast Hopelessness, which takes 30 seconds to complete. The cast cannot be interrupted and the adds are immune to crowd control. When the cast finishes, a pool of Soul Anguish will spawn, which deals damage to any raid members standing in it and also pacifies them. The damage the pool deals as well as its size depend on how much healing has been done to the Hopeless Reflection. If it receives no healing from the raid, then it will cover the entire room and will deal instant lethal damage to the entire raid. The more healing it receives, the smaller and less damaging the pool will be. If the reflection is healed to maximum health, the cast will instantly complete and the healers will be granted Lingering Hope, which restores 2% of maximum Mana every second for 5 seconds.
The new mechanics from Shadow Reflection: Erupting are also attached to the Hopeless Reflections in this phase.
Phase Four: Deceiver's Veil
Rupturing Singularities are also present in this phase on Mythic difficulty.
Strategy and Positioning
The same principles apply on Mythic to all the mechanics that carry over from the lesser difficulties. Heroism / Bloodlust should be used immediately on the pull.
Phase One
The main crux of this phase is the Erupting Reflections. They deal significant raid damage while they are alive and healing cooldowns are highly recommended. They should be dealt with as quickly as possible and represent the highest priority target in the encounter. Raid markers should be placed in a triangle around the boss denoting where they will be spawned by the affected players. It can be very helpful to assign specific DPS to each marker, however, you want to intentionally stagger the deaths of these reflections somewhat to make the Erupting Orbs easier to evade. If you kill all 3 simultaneously the platform will likely be overwhelmed. The players who were debuffed will need to immediately scatter to the edges of the platform, preferably also in a triangle-esque pattern to avoid the orbs overlapping and leaving no gaps. Once Erupting Orbs begin to spawn, a frantic dance will ensue; DPS is not a priority at this point and every member should focus wholly on ensuring they are not hit.
The secondary crux in this phase is the addition of the Wailing Reflections. This add should be burned down as soon as it spawns, though melee should take care. This add does follow the tank so it can be kited away from the melee stack to give them some breathing room.
Once the Wailing Reflection is killed, the affected tank will begin to take heavy damage from Lingering Wail. Ideally, this tank will not be tanking the boss unless heavy cooldowns are used. The Lingering Wail should not be dispelled until a Rupturing Singularity impacts. An assigned healer should then immediately dispel the DoT, gripping everyone to the tank and avoiding the knockback.
Rupturing Singularity knocks all players back much further on Mythic, as noted in the abilities section. Players will need to be as close as possible to avoid being knocked off the platform. If a Wailing Grasp is available, the raid can ignore the knockback provided the dispel is well timed.
Rogues should be soaking Armageddon Rain as much as possible, as they can use Cloak of Shadows to clear the debuff. Feint and Dense Concoction (if Assassination) can also be used to greatly reduce the damage if Cloak is unavailable.
Phase Two/First Intermission
Rupturing Singularitys occur in sequence in this phase, only seconds apart. In order to avoid being knocked off, the group must quickly assess the order in which the Singularities are falling. Once the order is ascertained, everyone must rush to the first Singularity to impact and position in such a way that they are knocked across the platform to the next Singularity about to impact. Failing to do so will result in a guaranteed wipe.
Rogues should continue soaking mechanics such as Armageddon Rain and Focused Dreadflame as much as possible, as they can use Cloak of Shadows and Feint to great effect. Depending on the number of Rogues you may be able to soak all Focused Dreadflame casts with Rogues exclusively and the use of external or personal cooldowns on the targeted player. Immunities from non-Rogue classes are also very helpful in reducing Focused Dreadflames impact on the raid.
Phase Three
The Shadow Reflection: Hopeless debuffs go out near the beginning of this Phase, which lines up with a Rupturing Singularity. The Hopeless Reflections themselves will spawn almost immediately after the knockback. It is ideal to have these reflections as stacked as possible. These Reflections need to be healed to full as fast as possible as they spawn during a period of relatively low raid damage, allowing the healers to quickly focus them. Throughput cooldowns are recommended, allowing the healers to quickly acquire their Lingering Hope buff and return to babysitting the raid. Armageddon and Bursting Dreadflame both occur ~15 seconds after the Hopeless Reflections spawn; if the Hopeless Reflections are not dealt with by that point it is very difficult to survive. Later spawns on the Hopeless Reflections are not as tight but it is still ideal to deal with them as soon as possible to avoid overlap with other mechanics.
The Wailing Reflections are also present in this phase and are handled the same way. The only caveat is that the healer assigned to dispel the Lingering Wail needs to ensure that the Rupturing Singularity does not knock them over a Soul Anguish zone, as they will be silenced, which prevents Wailing Grasp, leading to a wipe.
The Shadow Reflection: Erupting debuffs and Erupting Orbs are present as well, and are handled in the same fashion as before.
Phase Four/Second Intermission
Right before the second intermission, Kil'jaeden should be moved to the edge of the platform and the raid should fan out in a rough semicircle between the center of the platform and the current position of the boss. Illidan will always spawn within a certain distance of the boss, and this forces him to be in a much more predictable location allowing you to immediately obtain vision.
Rupturing Singularity occurs 10 seconds after the Deceiver's Veil cast completes. You can use a Demonic Gateway to avoid the first knockback by clicking it right as the Singularity is about to impact; you should use the Gateway around ~0.5s before the Singularity triggers. The second Singularity occurs 10 seconds following the first impacting; this one can be very difficult to survive. The raid can either manually find the Singularity and deal with it the same way as previous phases, or you can rely on personal movement cooldowns such as Heroic Leap, Shadowstep, and so on to eliminate the knockback effect. All Shadowsouls should be eliminated shortly after the second knockback, although faster is always better.
Phase Five
You should recast Heroism / Bloodlust as soon as it is available in this phase. This phase is identical to Heroic, but the emphasis is on different mechanics. Demonic Obelisks present the most lethal threats; the raid leader should use a raid marker to designate a safe spot. Taking a hit from an Obelisk will almost certainly be one shot.
Kiting the Flaming Orbs correctly is also essential, as the pools of flame they create are significantly larger on Mythic difficulty. There are some timings in this phase where the spawning of the Flaming Orbs will happen just before the Demonic Obelisks explode. In such cases, the raid will need to wait patiently for the orb to spawn and then quickly step to the safespot. If the group moves to the safe spot too early, the orb will spawn on the safespot and guarantee a wipe.
