Liberation of Undermine Raid Guide: Bosses, Loot, Mounts

Key Takeaways

• Liberation of Undermine was the second raid of The War Within, added in Patch 11.1 and opened March 4, 2025 with eight bosses.
• The canonical pull order ran Vexie and the Geargrinders first through Chrome King Gallywix last, not the order the LFR wings unlocked.
• Raid Finder opened across four wings: Shock and Awesome, Maniacal Machinist, Two Heads Are Better, and The Chrome King, on consecutive weeks from March 4.
• Final boss Chrome King Gallywix holed up in the Gallagio while Gazlowe and the united cartels stormed in to end his rule of Undermine.
• Season 2 tier sets dropped here, including the Death Knight's Cauldron Champion's Encore and the Evoker's Opulent Treasurescale's Hoard.
• Two mounts came off Gallywix: Prototype A.S.M.R. as an all-difficulty rare drop and Keys to the Big G from Mythic.

The raid has been live for well over a year, so this is a settled look back at how it was built, who you fought, and what it dropped.

Inside Gallywix's Gallagio

Liberation of Undermine launched with Patch 11.1, which went live on February 25, 2025, and the raid itself opened its doors on March 4. The setting was Undermine, the goblin capital, with Jastor Gallywix barricaded inside his gaudy Gallagio casino and surrounded by hired muscle and cartel benefactors. The story hook was a goblin uprising: Gazlowe and the united cartels pushed through the fortifications to topple the self-styled Chrome King. If reliving the fight makes you want a fresh run through it, you can Book a full raid clear with a team that already knows the route.

The Eight Bosses in Pull Order

The raid's in-game encounter order is not the same as the order its Raid Finder wings unlocked, which trips up anyone reading an old launch calendar. Here is the canonical pull order from the first boss to the last:

1. Vexie and the Geargrinders
2. Cauldron of Carnage
3. Rik Reverb
4. Stix Bunkjunker
5. Sprocketmonger Lockenstock
6. One-Armed Bandit
7. Mug'Zee, Heads of Security
8. Chrome King Gallywix

Gallywix sat at the top of that list as the capstone fight, and a Mythic kill on him also handed out a prestige title. Groups chasing only the final encounter could Book a Chrome King Gallywix kill without committing to the full eight-boss run.

How the LFR Wings Unlocked

When the raid launched, Raid Finder opened its four wings on a weekly schedule rather than all at once. Vexie sits first in the pull order but her wing opened in week three, which is why the release calendar reads out of sequence with the encounter list. The wings unlocked as follows:

Story Mode became available on March 11, a week after the raid opened, giving solo players a lower-pressure path through the campaign beats. That launch calendar is now historical, since every wing has long since been open.

Class Tier Sets from Undermine

Undermine dropped the Season 2 tier sets, each a nine-slot collection with set bonuses that reward mixing pieces. Five of the class sets are named below, and the full slate is broken down on the tier set overview:

• Death Knight: Cauldron Champion's Encore
• Demon Hunter: Fel-Dealer's Contraband
• Druid: Roots of Reclaiming Blight
• Evoker: Opulent Treasurescale's Hoard
• Hunter: Tireless Collector's Bounties

Set pieces came from bosses across the raid rather than a single drop table, so a full four-piece bonus meant clearing a spread of the eight encounters rather than farming one wing.

Mounts and Collectibles

Both raid mounts dropped from Chrome King Gallywix. Prototype A.S.M.R. was an extremely rare chance off every difficulty, so even Raid Finder groups had a shot at it. Keys to the Big G came from Mythic Gallywix specifically, at a steady drop rate that held until the next expansion arrived, after which it fell to a much rarer chance. Both are the kind of goblin-tech trophy collectors still chase on old lockouts.

Frequently Asked Questions

How many bosses are in Liberation of Undermine?

Eight. In pull order they are Vexie and the Geargrinders, Cauldron of Carnage, Rik Reverb, Stix Bunkjunker, Sprocketmonger Lockenstock, One-Armed Bandit, Mug'Zee, and Chrome King Gallywix. Gallywix is the final encounter.

When did the Liberation of Undermine raid open?

The raid opened on March 4, 2025, roughly a week after Patch 11.1 launched on February 25. Normal, Heroic, Mythic, and the first Raid Finder wing all opened together, with Story Mode following on March 11.

Why does the LFR schedule not match the boss order?

Raid Finder wings release on their own calendar, grouped for pacing rather than by pull order. Vexie is the first boss in the raid but her wing, Two Heads Are Better, opened in the third week, on March 18. The encounter order and the wing-release order are simply two different things.

What mounts drop in the raid?

Prototype A.S.M.R. and Keys to the Big G, both from Chrome King Gallywix. Prototype A.S.M.R. is a rare drop on all difficulties, while Keys to the Big G comes from Mythic Gallywix. The Mythic mount held its drop rate until the following expansion, then became far rarer.

Who is the final boss of the raid?

Chrome King Gallywix, the goblin trade prince barricaded in the Gallagio. He is the eighth and final encounter, and a Mythic kill on him awarded a prestige title on top of his mount and gear.

What expansion and patch is the raid from?

Liberation of Undermine is the second raid of The War Within, released with Patch 11.1 in Season 2. It followed Nerub-ar Palace, the expansion's first raid, and centered on the goblin city of Undermine.
