Uldir
Raid GuideRetailBoss abilities and loot tables from Blizzard's own journal, boss by boss.
Millennia ago, seeking to understand the nature of their eternal foe, the titans constructed this sprawling underground facility to research and quarantine captured specimens. They hoped that by studying the void energy that bound the Old Gods, probing it for weaknesses and reactions, they could find some way to neutralize it. They were horribly, horribly wrong. The facility was sealed away, so that the horrors within would never be unleashed upon Azeroth. But now those seals have broken....
Written notes for this instance are a later milestone. Everything on this page comes from Blizzard's journal data.

Bosses
1. Taloc
The titan keepers enacted countless systems to detect and contain any breach from the facility. Their most powerful construct, Taloc, kept watch for any signs of corruption in the region and ruthlessly excised any that he found. But as thousands of years passed, its internal defenses began to decay, making it vulnerable to corruption.
Abilities
- Overview
Taloc's blood-fueled magic will flood the room with [Blood Storms]. His powerful [Cudgel of Gore] will absorb nearby [Blood Storms]. At 35% health, Taloc's fuel spills into the arena causing him to [Power Down] and spawn Coalesced Blood and Volatile Droplets. Volatile Droplets will continue to spawn once Taloc reabsorbs his fuel, canceling [Powered Down] and engaging the raid once more.

- Stage Two: Ruin's Descent

2. MOTHER
Uldir's titanic watcher was gifted with tenacity and an insatiable desire to discover a "solution" to the Old Gods. Her protocols have remained fully intact, even though many other systems in her facility have collapsed. WARNING: M.O.T.H.E.R. will not accept aid from contaminated subjects.
Abilities
- Overview
Pass through [Defense Grids] to reach the final chamber of the Hall of Sanitation.

3. Fetid Devourer

Abilities
- Overview
Periodically, Waste Disposal Units around the room will activate, dumping waste into the room and leaving behind Corruption Corpuscles. Players must kill these before they release [Enticing Essence], or Fetid Devourer will move to them and [Consume Corruption], healing and gaining energy. At 50% health, Fetid Devourer will enter into a [Fetid Frenzy].

Shortly after the Sundering, a dark messenger arrived on the fresh shores of Zandalar, intending to bring the newly isolated tribe into the service of N'Zoth.

He was captured, studied, disassembled, and stored in the Titans' Archives, where he has waited for a ch…

5. Vectis
The plague of corrupted blood killed countless trolls and began one of the most terrifying periods in Zandalar's history. The constructs within Uldir studied the disease in search of a cure, but found that only isolation and extermination was effective. Unfortunately, as the facility's safeguards cracked apart, the plague was accidentally combined with a sample of G'huun's blood, creating a new en…

Once the proud leader of the Zanchuli Council, highest advisors to the kings of Zandalar, Zul was praised as the greatest of prophets.

In Uldir, the titans had hoped to find a solution to the Old Gods. But when they experimented upon the Old Gods' unending, ravenous need to corrupt, they unexpectedly created a perfect avatar of that desire. G'huun is nothing but rot, pestilence, and decay, the ultimate parasite who cannot stop himself from consuming his host until it is gone.

To dislodge him from his lair, the Reorigination Drive must be fully charged by depositing [Power Matrices] within it. Once active, G'huun begins his assult in earnest.
