Overview
The Soulcoil Well sits in the middle of the room. Standing in it ticks Shadow damage and applies Soulcoiled to anyone who dies there. Every Restless Amani that reaches the water grants Nek'zali five energy and blasts the raid with Soulcoil Rite. Extra well feeds make Uncoiled Rage arrive early.
Keep adds off the well. Break Gravebound Advance with magic damage before the Amani commit to the water, tank her on the heaviest coffin spawn so melee can cleave, and keep the Possession Barrage lane empty. At 50% she hides behind Echoes of Jawae. After that window, Bloodlust and kill her before 100 energy.
Phase 1
Coffins light before Restless Amani climb out. Drag Nek'zali onto the denser spawn so the adds walk through the boss instead of a free path to the Soulcoil Well. Gravebound Advance is a magic absorb, so ranged casters (not Hunters) should rip it, then Death Grip or knockbacks finish the gather. Dead Amani leave Vessel of Awakening corpses and a 15-yard Corpse Blight. Burn leftover bodies or they revive.
Soulcoil Ignition is the big scripted energy spike. She triggers Soulcoil Rite several times in a row and covers the raid with Ritual Burn. Healers cover that overlap. Everyone else sidesteps Anguished Echoes. Go into Ignition with no Ritual Burn stacks.
Essence Rend yanks random players toward the center, then leaves a dispellable DoT. Walk to a safe outer edge before the dispel. The drop is a Latent Cultist puddle that stays for the rest of the fight. Possession Barrage fires four spirits at the active tank. They explode on the first player they hit, spawn Restless Amani there, and raid damage falls off with distance, so that tank stands at least 30 yards out and nobody stands in the lane. Each echo also applies Hollowing Strikes to whoever it hits. Melee applies the same stack, so swap around five or six stacks, ideally as Barrage ends so the offtank taunts into a clean window.
Intermission
At 50% she becomes immune. Soul Transfer channels into an Echo of Jawae. Move out of the beam before it finishes. Kill both Echoes to break the tethers and pull her back in. Restless Amani keep spawning, so the same well rules still apply.
Hungering Pyre is a group soak on a random player. Send melee into it, and plant the circle on a corpse pile so the soak deletes leftover add bodies. Players who skip the soak pick up Slithering Flame and can mop stray corpses. Corpses left from earlier revive here.
Phase 2
Bloodlust as soon as she is attackable. Uncoiling ticks Shadow damage for the rest of the fight. Invoke reapplies Soulcoil Rite so the DoT no longer drops, and shoves Latent Cultist puddles. Kill her before she hits 100 energy.
Uncoiled Rage is a wipe: 500% damage done plus a sprint. If the well was already fed, this window is shorter. Call leftover Amani immediately and do not greed a puddle soak during Invoke.
By role
Tanks
Face her at the entrance, then walk her onto glowing coffins. Sprint 30 yards out for Possession Barrage and keep the lane empty. After the volley, gather the Restless Amani that spawned on you. Swap Hollowing Strikes at five or six stacks. In the intermission, park Hungering Pyre on corpses.
Healers
Do not instant-dispel Essence Rend. Wait until the target has reached the edge. Ramp Soulcoil Ignition together with Ritual Burn. The last phase is a stacking Soulcoil Rite race, so hold a cooldown for Invoke.
DPS
Break Gravebound Advance with magic damage, then kill Amani before they touch the Soulcoil Well. Burn Vessel of Awakening bodies before Corpse Blight spreads. Soak Hungering Pyre as assigned, or skip it for Slithering Flame and mop strays. Kill both Echoes of Jawae. Lust after the intermission and finish her before Uncoiled Rage.
Why pulls die
Back-to-back well feeds turn the next Soulcoil Rite into a healer check you cannot cover, especially when Ritual Burn lands on the same Ignition. Possession Barrage wipes happen when someone stands in the lane, the tank is too close, or an echo tags a player with extra Hollowing Strikes. Intermission deaths are solo Hungering Pyre soaks or leftover Vessel of Awakening corpses. Later deaths follow Invoke puddle moves stacked on Uncoiling.

What actually wipes a Nek'zali pull?
The Soulcoil Well. Each Restless Amani that drinks grants five energy and applies Soulcoil Rite. At 100 energy she casts Uncoiled Rage.
When does the intermission start?
At 50% health she becomes immune behind two Echoes of Jawae. Kill both Echoes to break the tethers and pull her back in.
Where do you Bloodlust?
After the intermission, as soon as she is attackable. Kill her before 100 energy.
