Scalecommander Sarkareth

As leader of the Sundered Flame, Scalecommander Sarkareth broke away from the rest of the dracthyr to forge a new future. He has since led his forces to Aberrus, intent on claiming the legacy he believes rightfully belongs to his kind and willing to do anything to obtain it.

Abilities & Strategy

Overview

Scalecommander Sarkareth begins the fight with Oppressing Howl and attempts to obliterate players with Glittering Surge. When weakened, he draws upon the power of the Void to enhance his draconic powers, using Abyssal Breath and Ebon Might to summon and strengthen images of himself. When severely wounded, Sarkareth destroys the room to fully draw in powers of the Void and convert his abilities to their most powerful forms.

Kazzara, the Hellforged

Although Neltharion would not use them himself until much later, he experimented with elementium plating in the early days of Aberrus. The end result of elementium and shadowflame was Kazzara, who was deemed far too unstable for release. Driven mad by the excruciating pain of her elementium plates, she now serves as the guardian of the Shadowed Crucible.

Abilities & Strategy

Overview

As combat unfolds, Kazzara tears open Dread Rifts from which Rays of Anguish will form to hunt players. At 80%, 60%, and 40% health remaining, plates of Kazzara's menacing armor are shattered off during Hellsteel Carnage, intensifying her Infernal Heart.

Tanks
  • Terror Claws inflict heavy damage and increase damage taken from further casts.
  • Upon reaching 100 energy, Hellbeam is unleashed inflicting massive damage to anyone caught in the effect.

Echo of Neltharion

Tucked away in the depths of the Shadowed Crucible, Neltharion's sanctum was a place of refuge and research for the Earth-Warder. Some say that echoes of his powerful presence still linger here, contemplating the future of the black dragonflight and how to obtain the power to ensure its success.

Abilities & Strategy

Overview

The Echo of Neltharion periodically raises walls of Twisted Earth throughout the chamber. As the battle begins, Neltharion causes Echoing Fissures to erupt in the newly confined space. Upon reaching 60% remaining health, Neltharion Surrenders to Corruption, summoning Voices From Beyond throughout the chamber. Once all Voices From Beyond are slain, Neltharion begins to rip open portals to overwhelm players with Twisted Abberations and the might of his Ebon Destruction.

Tanks
Damage Dealers
  • Rushing Darkness knocks players backwards with enough force to destroy Twisted Earth.
  • Neltharion protects himself with Shadow Barrier upon reaching 35% health if any Voices From Beyond remain.

Assault of the Zaqali

Led by Warlord Kagni, the Zaqali warband has launched an all-out assault against the Shadowed Crucible in search of their missing Elder, Rashok. Brutal and ruthless, Kagni is willing to employ any tactic to succeed.

Abilities & Strategy

Overview

As the battle begins, Warlord Kagni calls upon his Zaqali warband to assault the two protruding battlements. Warlord Kagni periodically sends himself onto the opposing battlement with Devastating Leap and causes Cave Rubble to fall with Heavy Cudgel.

Rashok, the Elder

Imprisoned within Aberrus for a millennia, the Zaqali elder Rashok has been perpetually drained of the raging flame within him to power Neltharion's twisted laboratory. Existing on the edge of death for so long has driven the elder mad. Should he break free, his vengeance will scour the Shadowed Crucible's halls.

Abilities & Strategy

Overview

Rashok gradually gains energy over time while outside the Elder's Conduit. At 100 energy, Rashok gains Ancient Fury and begins to pulse deadly Shadowflame damage. Rashok's powerful Searing Slam creates a Lava Vortex which pours forth Lava Wave across the chamber.

Magmorax

Raised from a pup by Neltharion, the only thing stronger than the loyalty of Magmorax is his appetite. The lava hydra guards the passage into the deepest chambers of the Shadowed Crucible, keeping his master's secrets safely hidden from prying eyes.

The Forgotten Experiments

The development of the dracthyr produced many iterations, some more successful than others. Early versions of the experiment proved far too volatile to destroy. Kept dormant for thousands of years, these creations have now awakened, and seek to test their prowess against the champions of Azeroth.

Abilities & Strategy

Overview

The forgotten experiments within Neltharion's laboratory each represent a dark stage in the development of the dracthyr. Neldris enters the fray first and assaults the laboratory's intruders with Rending Charge. Upon Neldris' defeat, Thadrion bursts from his containment vat, afflicting players with Unstable Essence and belching forth Volatile Spew. As Rionthus' predecessor is defeated, he escapes his containment vat and begins to devastate the chamber with Neltharion's most potent version of Deep Breath. As Neldris reaches 50% remaining health, Thadrion bursts from his containment vat, afflcting players with Unstable Essence and erupting with Volatile Spew. As Thadrion reaches 50% remaining health, Rionthus escapes his containment vat and begins to devastate the chamber with Neltharion's most potent version of Deep Breath.

The Vigilant Steward, Zskarn

Long ago, Zskarn was tasked with testing the mettle of Neltharion's experiments. Only the most powerful would pass muster and keep their lives. The latest visitors to the Shadowed Crucible have attracted his unwavering attention--but his approval will be much harder to earn.

Abilities & Strategy

A master at manipulating the battlefield, Zskarn utilizes several deadly traps to test the capabilities of players. Zskarn creates Dragonfire Golems to aid him by activating nearby Dragonfire Traps to burn players in the vicinity. Zskarn passively generates energy, and upon reaching 100 energy unleashes waves of Tactical Destruction from nearby Dragon Statues to decimate players.

Tanks
  • Tactical Destruction unleashes multiple waves of Dragonfire from nearby dragon statues that are lethal to players caught within.
  • Searing Claws inflicts increasing Fire damage to Zskarn's current target with each swing.
