This fight is 3 Phases with an Intermission. Phase 1 is single target, Phase 2 is two target spread cleave, and Phase 3 is two target stacked cleave.
All phases have Orbs, Ghosts, or both, that need to be loosely stacked. A frontal tank cone will destroy them.

Phase 3 has mechanics from both P1 and P2.
Destroying Orbs also applies a stacking DOT debuff.
Axes don't despawn.
Guillotine soaks apply a 500% vulnerability. Prepare two alternating soak groups.
Spiteful Soulcoiler is a new P2 and P3 add that casts a raidwide fear and needs to be interrupted.
There is a new Purple Orb. You can't touch any other Orbs with it.
Picking up an Orb gives you a 200% vulnerability for 10s.
Only the target fixated by each Ghost can see it. Ghosts also deal massive damage if they touch.
Spiteful Soulcoiler have a 99% damage reduction that can be removed by hitting it with Gloombomb.

Stage One: Serpent's Bargain
Everyone
Be prepared for massive raidwide
damage, and avoid the puddles.

Everyone
Pick up Orbs and move
them into clusters

Walking over an Orb will pick it up for 5s and give the holder a DOT debuff. After 5s, the Orb is dropped again.
You'll destroy Orbs with Sever, a tank frontal. Pick up and move Orbs into clusters to destroy several at once.
On Mythic difficulty, after carrying an Orb, you get a 200% vulnerability to carrying Orbs for 10s.
Everyone
Use the cone to destroy
clusters of Orbs
Frontal cone aimed at the tank. Deals massive physical damage and applies a 200% vulnerability to any players hit.
Aim this frontal at clusters of Orbs to destroy them.
Each Orb does a burst of raidwide damage when destroyed, so you can't hit too many at once.
Any Orbs left at the end of the phase will be destroyed, so you can't leave too many behind either.
On Heroic, Orbs also apply stacks of a raidwide DOT debuff when destroyed.
Everyone
Move Purple Orbs without
touching any other Orbs
Everyone
Help soak,
then run away.

Dodge the axes
Stage Two: Usurper's Reprisal (After killing Zul'jan)
Everyone

stop mind controls
Everyone
Kite Ghosts into a cluster by looking
away, then look at them so they stop.
Manifestation of Dread are Ghosts that spawn and fixate players.
They chase you, but stand still when you look at them.
If it touches you, it mind controls you.
Try to kite these Ghosts into a loose clump so that they can be destroyed by Soul Sever, a tank frontal.

Everyone
Use the cone to destroy
clusters of Ghosts
Everyone
Dodge and break
the shield quickly
Everyone
Interrupt and
kill the add.
Malacrass summons a Spiteful Soulcoiler. It will spam cast Wail of Terror, a raidwide fear that you need to interrupt.
It also deals damage to random players while alive.
Kill the add before it reaches full energy, because it will become immune to interrupts.
It will move away after every interrupt, so mostly ranged will have to handle it.
Everyone
Use Gloombomb circles
to remove damage reduction
Everyone
Move out with the debuff,
then collect your clones.
Intermission: The Claimed Vessel (After killing Hex Lord Malacrass)
Everyone
Damage amp, pop
bloodlust and hit Zul'jan!
Everyone
Move to block souls,
but watch the raid health.

You can block them by moving in their way, but they deal raidwide damage when blocked.

On Mythic, blocking a Soul applies a raidwide 20% vulnerability debuff for 2s.
Stage Three: Coiled Union (After Soulbinding channel ends)
