Nek'zali the Soulcoiler

The boss enrages at full energy. Each Soulcoil Ignition channel will add 25 energy.

If an add walks to the Well, it adds 5 more energy.

Too many adds walking in will push boss to enrage.

Nek'zali teleports to center and channels, applying 5 stacks of the Soulcoil Rite DoT and creating circles to dodge. 

This channel gives the boss 25 energy.

On Heroic, Soulcoil Rite also gives the Ritual Burn debuff, a stacking 15% vulnerability.

Periodically, Amani skeletons adds spawn around the room, indicated by glowing coffins.

Each spawn with a 25% health absorb shield and walk slowly toward the center of the room.

Breaking their shield stops them from walking toward the Well.

If one reaches the Well, it causes a stack of Soulcoil Rite DoT on all players and gives the boss 5 energy.

A barrage of ghosts shoot out in a line toward the tank. They explode on impact, with damage reduced by distance.

The tank should move away from the raid.

The raid must avoid being hit by any ghosts in the line as they shoot out, so everyone should stand behind the boss.

Two mobs spawn on opposite sides of the room.

Nek'zali is immune until they both are killed, which ends the phase.

Circle soak on the active tank. A few players should help soak.

Players who don't soak will be marked with the Slithering Flame DoT.

Several players are pulled slightly before being knocked back and given a dispellable debuff.

Debuffed players drop a Latent Cultist puddle at their feet when the debuff ends or is dispelled. 

Latent Cultists are ghostly images with a circle around them that float around the room as a form of area denial. Drop them at the edges.
