Mythic L'ura Phase 4: The Secret Phase Guide

This guide focuses exclusively on Phase 4: the secret phase. For Phases 1 through 3, the rest of the internet exists. You presumably survived those phases to get here, so we will charitably assume you understand how Death's Dirge works, what happens in the Darkwell, and why your Dawn Crystals keep shattering in Phase 3. If not: reread Phase 3 until you deserve Phase 4.

Phase 4 Overview: What Blizzard Hid From You

Phase 4 is triggered when L'ura reaches 0% health for the first time during Phase 3. Rather than dying like a normal boss that respects your time investment, she casts Reintegration, reforms with 100% health, and transforms into her Dark Archangel form. The phase is exclusive to Mythic difficulty and was not discoverable through conventional testing, having been deliberately hidden from datamining during the beta period.

The phase begins with a new environment state: the Darkwell surges with intensified void energy, the room floods with shadowy Sha constructs summoned in constant waves, and L'ura immediately begins casting Heaven & Hell: a massive void-tornado that targets a single player and follows them relentlessly around the room.

The apparent compensation for having to kill the boss twice from full health is that raiders deal bonus damage throughout Phase 4. Do not let that comfort you. "Bonus damage" is Blizzard's polite way of saying "you will need every percent of World of Warcraft mounts."

L'ura casts Reintegration at 0% Health

Phase 3 ends when L'ura reaches 0% HP. She does not die. She casts Reintegration and resets to 100% health. Phase 4 begins immediately with no pause. Players who celebrate and remove their headsets are no longer your problem: or yours is now a 19-man progression group. Healers should use a raid cooldown immediately on transition.

Heaven & Hell: The Tornado You Now Live With

Heaven & Hell is Phase 4's defining mechanic and the primary reason your raid floor will look like an abstract void painting within fifteen seconds of the phase starting. A single player is targeted and becomes the anchor point for a slow-moving but persistent void-tornado. There is no duration: it follows the target for the remainder of the encounter or until the target dies, at which point it is assumed to transfer or reset (limited data exists at time of writing, as the phase has been seen by essentially no one alive).

The kiting player must establish a predictable orbit pattern around the room: circular paths work best: while the rest of the raid maintains awareness of that player's position at all times. Running through the raid to "reset" the tornado's position is a 20-person punishment, not a personal creative choice.

POSITIONING NOTE: With Heaven & Hell and Sha waves both active simultaneously, the effective safe space in the room shrinks dramatically. Assign sectors: the kiting player owns the outer ring; The Last Light bearers own the midfield; melee and tanks keep the center. This is not a suggestion.

The Last Light: Your Desperately Thin Safety Net

Certain players: exact selection criteria are not yet fully documented: receive an Extra Action Button granting access to The Last Light, a frontal holy cone that vaporizes Sha constructs in its path. Given the rate of Sha spawning, these players are the only functional AoE answer available.

Whoever holds this button is more important than your top-parsing warlock, and everyone in the raid needs to know it. The Last Light bearers must be:

• Mobile enough to reposition for maximum cone coverage
• Alive: which means healers need to track them specifically
• Coordinated with one another to avoid redundant angles
• Not also the player being chased by Heaven & Hell, ideally

Sha Wave Management: Welcome to Your New Full-Time Job

The Sha constructs do not pause. They do not slow down on a timer. From the moment Phase 4 begins until the boss dies or your raid does, waves of shadowy Sha continuously spawn from the perimeter and walk toward player positions. They are not individually threatening; collectively they are a raid-wiping carpet if ignored for more than a few seconds.

The interaction between Sha waves, the Heaven & Hell kiting path, and Last Light cone angles creates a dynamic room-state that requires constant adjustment. Pre-assigned static positions will fail within thirty seconds. Call out Sha density. Call out tornado position. Call out when Last Light is being used so the rest of the raid knows when the adds are about to be cleared and can stop panic-running into each other.

Phase Transitions at a Glance

You burned cooldowns in Phase 3 to survive the enrage window and actually reach 0% health. Phase 4 begins immediately with no recovery pause. Your healers are hurting, your tanks are at questionable health, and you now have a fresh 100% health boss plus a tornado plus infinite adds. Planning cooldown usage across the full fight with Phase 4 in mind is no longer optional: it is the difference between a progression kill and a 419th wipe.

1. Transition cooldown: Assign one major healing cooldown to fire the instant Reintegration is cast. No exceptions. This is not "nice to have."
2. Sha density cooldown: Reserve at least one AoE damage cooldown: Death and Decay, Consecration, Wild Spirits, whatever your composition allows: for the first major Sha surge approximately 10-15 seconds into Phase 4.
3. Shattered Sky cooldown: When Shattered Sky lands, the raid is already managing tornado, adds, and a damage race. A healing cooldown here saves lives. Assign it before the pull, not during the cast.
4. Bloodlust / Heroism / Time Warp: The community consensus forming in early progression is to hold Bloodlust for Phase 4 given its shorter overall health pool and the bonus damage modifier. That said, if your raid cannot survive Phase 3 reliably enough to reach Phase 4 consistently, use it in Phase 3 and re-evaluate. Do not theoretically optimize for a phase you see once every forty pulls.

Role Responsibilities in Phase 4

Tanks

Tank damage from L'ura in Phase 4 remains a factor despite the chaos. Standard tank swap coordination applies. The more pressing responsibility is awareness of the Heaven & Hell tornado path: do not position L'ura in a location that forces the kiting player to run through melee range. Boss positioning in the center of the room is strongly preferred; do not walk her into corners chasing threat.

Healers

You are triaging simultaneously: transition damage, sustained Shattered Sky ticks, Sha contact damage on anyone caught in a bad position, and the Heaven & Hell carrier. Identify your Last Light bearers and keep them alive at the expense of anyone who stood in the tornado. This is an extremely sarcastic joke, but also accurate prioritization.

DPS: General

Bonus damage is active. The boss needs to die before your cooldowns expire and the Sha density becomes unmanageable. Target priority: L'ura when Sha count is acceptable; Sha via cleave or area abilities when density threatens the raid. Do not fall into the trap of fixating on the boss while adds eat your healers.

Last Light Bearers

You are the most important players in this phase and you know it, so please do not let that go to your head. Use The Last Light to hit the maximum number of Sha per cast, coordinate angles, and communicate your charges. Die last. Not because you are more valuable as a person, but because the Sha will eat the raid if you are not alive to cast.

Loot & Rewards

Because you are killing the same boss twice, you receive loot once. This is the reward for your suffering. Midnight Falls drops ilvl 282 Mythic gear, the Chiming Void Curio omni-token exchangeable for any Tier 35 slot, and the pride of knowing you have cleared the most difficult encounter in Isle of Quel'Danas.

For the truly masochistic, completing Mythic Midnight Falls before the next raid tier releases awards Cutting Edge: Midnight Falls. This achievement comes with a cosmetic reward and the permanent, irrefutable proof that you were better than almost everyone at World of Warcraft during Season 1. Whether that is a personality trait or a life goal is between you and your social World of Warcraft coaching service.

Final Notes on Progression

At time of writing, Team Liquid's best attempt in Phase 4 has been 94.7% health: meaning the boss has reached the secret phase a total of twice across all guilds globally, and has not been killed. No other guild has even seen Phase 4. This guide is, in some meaningful sense, written slightly ahead of the world's collective knowledge, assembled from partial data and the panicked stream reactions of twenty very tired professional raiders.

What is known with certainty: Phase 4 exists. It begins with Reintegration. It features Heaven & Hell and constant Sha waves cleared by The Last Light. It ends when L'ura reaches 0% health a second time, presumably without a third phase, though Blizzard's track record in this raid has made certainty a luxury.

Good luck. You will need it more than you needed it in Phase 3, which you thought was the hardest thing you would ever do in this game. It was not.
