Where These Pieces Drop
5 of this set's 15 pieces drop from 4 encounters in Aberrus, the Shadowed Crucible. The rest come from vendors, quests, crafting or world drops, which the dungeon journal does not record.
Drop chances are not stored in the client data we mine, so none are shown here.
Where to Farm This Set
4 bosses in Aberrus, the Shadowed Crucible drop pieces of this set. Each instance below carries its Adventure Guide entry, where its entrance is, and what each boss drops.
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 entrance is in Zaralek Cavern at 48.5, 10.0 (/way #2133 48.5 10.0).
Aberrus, the Shadowed Crucible entrance
The Amalgamation Chamber drops 1 piece of this set (Waist). Adventure Guide map pin: 44.4, 63.6 on the Aberrus, the Shadowed Crucible map. The Eternal Blaze burns with the heat of a thousand suns, while the Essence of Shadow blooms with darkness incarnate. Although exceptionally powerful on their own, when combined they surge with the unchecked might of shadowflame, creating a whirlwind of ultimate destruction.
Rashok, the Elder drops 1 piece of this set (Wrist). Adventure Guide map pin: 67.5, 21.8 on the Aberrus, the Shadowed Crucible map. 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.
The Vigilant Steward, Zskarn drops 1 piece of this set (Back). Adventure Guide map pin: 51.3, 24.5 on the Aberrus, the Shadowed Crucible map. 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.
Scalecommander Sarkareth drops 2 pieces of this set (Legs, Feet). Adventure Guide map pin: 49.0, 71.3 on the Aberrus, the Shadowed Crucible map. 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.

Versions and Companion Sets
The game links 1 other version to Legacy of Obsidian Secrets, each labelled the way the collection journal labels it. This page is the Heroic version.
1 other set reuses the 3D models of Legacy of Obsidian Secrets’s head, shoulder, chest, waist, legs, feet and hands, most shared models first:
Obsidian Gladiator's Chain Armor (Dragonflight, 33 pieces): the same head, shoulder, chest, waist, legs, feet and hands models, recoloured.
Matched in the game files: each piece’s ItemDisplayInfo names its 3D model and texture. The same model with another texture is a recolour. Only pieces with a 3D model of their own (helms, shoulders, cloaks, weapons, shields, off-hands and some belts and robes) can be compared this way; pieces drawn from textures alone are left out.
