Aberrus, the Shadowed Crucible

Aberrus, the Shadowed Crucible is the second raid in, added in patch 10.1.0. Hidden beneath the Obsidian Citadel, it is a massive laboratory in Zaralek Cavern where Neltharion's most horrid creations were made, including the dracthyr.

Aberrus is located at the northern end of Zaralek Cavern, at the Aberrus Approach. Dragonride from Valdrakken through Iridikron's Gambit at on the border between Ohn'ahran Plains and Thaldraszus. Bear north once the tunnel opens up into the greater cavern to reach the approach, instance line, and summoning stone.

Players are breadcrumbed to the raid via the final quest in chapter five of the Embers of Neltharion campaign: Aberrus, the Shadowed Crucible: Sarkareth.

Millennia ago, Neltharion established Aberrus, a secret laboratory where he conducted world altering experiments. Recently rediscovered, Aberrus is now under attack from all sides as forces seeking to claim the Earth-Warder's legacy search for any power that remains. The champions of Azeroth must venture into the shadows and ensure Neltharion's dark power doesn't fall into the wrong hands.

The nine boss encounters are divided into four wings, which, on raid finder difficulty, open on a two-week cycle.

Neglected for millenia [sic], Neltharion's crations have twisted into something monstrous.

• Kazzara, the Hellforged: Before Deathwing, there were many attempts to infuse a subject with Shadowflame. The only one that survived was Kazzara. Driven mad by the excruciating pain inflicted by her elementium plates, she now serves as the ferocious guardian of the Shadowed Crucible.
• The Amalgamation Chamber: The creation of Shadowflame destroyed countless elementals. Now only the strongest remain, Krozgoth and Moltannia. One of shadow, the other fire, these powerful elementals combine their powers to create a force of ultimate destruction.
• The Forgotten Experiments: On the road to develop dracthyr there were many failures. Some of these early versions were too volatile to destroy, and instead kept dormant to protect the world from their brutality. Now they awaken to test their prowess against the champions of Azeroth.

• The Zaqali warband has launched a devastating assault on the crucible in order to destroy anything in their path.
• Assault of the Zaqali: Warlord Kagni leads the Zaqali warband against the crucible. Brutal and Ruthless, Kagni is willing to employ any tactic in order to win.
• Rashok, the Elder: Rashok, once a great leader of the Zaqali, was imprisoned within these halls for millennia. His molten blood constantly siphoned to power the crucible, the elder was kept on the brink of death driving him mad. Due to the recent chaos, Rashok has broken his restraints and seeks revenge on any that cross his path.
• The Vigilant Steward, Zskarn: Zskarn walked these halls when they were first formed and bore witness to Neltharion's many profound experiments. Now that the crucible stirs with power once more, Zskarn will stop at nothing to claim the crucible and continue his master's legacy.

• Something stirs in the dark... it once corrupted the Earth-Warder, and now it is eager to claim new victims.
• Magmorax: Its eyes never close. Its will never breaks. Magmorax, the beast of legend, guards the passage into the deepest chambers of the Shadowed Crucible.
• Echo of Neltharion: Before the name Deathwing was whispered in terror, Neltharion was known as the Earth-Warder. During this time, the Aspect of Earth used his power to construct a massive hall deep beneath the surface where he accumulated secret knowledge. A visage of the black dragon still resides within the crucible, waiting for an opportunity to continue the work started so long ago... at any cost.

Sarkareth stands at the edge of the ahvssl seeking to harness Neltharion's power and claim the former Earth-Warder's legacy.

• Scalecommander Sarkareth: Formerly one of the five Scalecommanders of the dracthyr, Sarkareth broke away to rebel against the dragonflights. Now leader of the Sundered Flame, Sarkareth leads an army into Neltharion's Shadowed Crucible to claim the power within and use it to overthrow the aspects.

As in past raids, the item level of loot varies based on which boss drops it:

• Early: Kazzara the Hellforged, The Amalgamation Chamber, Assault on the Zaqali
• Mid: The Forgotten Experiments, Rashok
• Late: Zskarn, Magmorax
• Final: Echo of Neltharion, Scalecommander Sarkareth

Some notable items can also be found in the raid. They have a +6-7 item level bonus compared to normal drops from their bosses:

• Idol of Chaotic Arrogance, Idol of Domineering Arrogance, Idol of Debilitating Arrogance, Echo of Neltharion

After the cutscene, Wrathion and Sabellian have gossip:

• Wrathion gossip
• It will take time for Sabellion [sic] and I to understand the meaning of what we've witnessed here.
• Sabellian gossip
• I need some time to think about what I have seen.
