Raid Setup
Introduction
Fight Style: Single Target Fight
Recommended Setup: 2 Tanks / 4 Healers / 14+ DPS
Useful utilities: A second monitor to watch Netflix during the boss fight
Easy Mode
This boss is fairly easy on every difficulty, so here are some Netflix recommendations instead: The Witcher, The Night Agent, Love is Blind and Mighty Morphin Power Rangers: Once & Always.
The 
Awakened version of the fight is just as easy as it was before, so here are some updated Netflix recommendations: The Gentlemen and 3 Body Problem.
But seriously, apart from dodging swirls and the Hellbeam frontal, just make sure to destroy Dread Rifts with Rays of Anguish (laser that follows you, kite it into the Dread Rift circle).
Mechanics
When Kazzara reaches 70%, 50% and 30% HP, the raid will take 93,612 Shadowflame damage, and a permanent DoT will be applied to the entire raid. The DoT deals 31,204 Shadowflame damage every 4 seconds, increasing in speed as the boss’ health gets lower.
Additionally, Hellsteel Fragments and Revenants Blood puddles will spawn on the ground that need to be avoided.
Marks several players, after 5 seconds they will drop a Rift (puddle) and hit any player standing within 5 yards for 109,213 Shadowflame damage. Standing in the puddle will inflict additional damage. Additional players per set will get targeted by this when the boss' health is at 70%, 50% and 30%.
The Rifts are used to remove Rays of Anguish.
Random players are targeted by a laser (Red Arrow) that follows them around, inflicting 62,408 Shadowflame damage every 0.3 seconds and drops fire puddles on the ground. Kite it into a Dread Rift to remove it.
When Kazzara reaches 100 energy, she will target a random player and cast a fire breath in their direction, dealing 140,417 Shadowflame damage every 0.3 seconds.
Simply avoid this.
Small knockback that deals 78,010 Shadowflame damage to all players and adds a small DoT that ticks for 18,722 Shadowflame damage every 2 seconds for 20 seconds.
Strategy
Opening Positions
Tanks should keep the boss where she is standing and face her away from the raid. Even though she does no frontal attack, facing her away will help with awareness when the boss uses her Hellbeam ability (she will do a 180 turn). Tank swap each Terror Claws unless you want to test your limits.
Pop Hero/Lust on pull, and loosely spread behind the boss to not get caught by random lasers spawning on nearby players and to bait other abilities. The boss will reach 70% fairly quickly, so be ready to dodge puddles and to take raid wide damage.
The puddles she spawns when she hits 70%, 50% and 30% hit pretty hard, so avoid at all cost.
The Hellsteel Fragments only spawn at those breakpoints, but Revenant’s Blood puddles spawn throughout the fight at increasing intensity the lower the boss' health is.
When the lasers spawn, kite them into the Dread Rifts puddles. The placement of Dread Rifts does not matter much as there is plenty of space behind the boss (just don’t place them too far away, as that will force players to kite for longer).
At 100 energy, be ready to dodge the frontal breath ability (Hellbeam). She will lock her position once she starts casting, so just dodge once.
The Wings of Extinction cast will do a small knockback, so just try not to get knocked into a laser/puddle, to avoid taking unnecessary damage.
When the boss is below 30% health, the raid-wide damage will ramp up pretty high, so be extra careful to avoid taking unnecessary damage from other abilities, as this will most likely lead to deaths at this point.
