Liberation of Undermine is an eight-boss tier built around Gallagio Casino glamour and goblin tech, and the loot table is front-loaded with the things people actually log in for: tier tokens, a handful of busted trinkets, and a weapon pool that decides half the meta. The mistake most people make is killing bosses in pull order and hoping the right item falls out. It doesn't work that way. Some bosses gate your tier set, a couple gate your best trinket, and a few drop nothing you'll wear past the first reclear. Here's the priority that actually matters, boss by boss.

How tier set tokens are split across the eight bosses

Before single drops, sort out your 4-set. In Liberation of Undermine the class set tokens come from six of the eight encounters, grouped by slot. The split runs roughly:

  • Head and Shoulders drop from the earlier and mid-tier bosses — these are the ones you want first because shoulders plus one more piece already opens the 2-set.
  • Hands and Legs sit in the middle of the instance.
  • Chest comes off a later boss, and the final two encounters do not drop tier tokens at all — they drop weapons and the high-end trinkets instead.

The practical takeaway: your 4-set is fully obtainable without ever seeing the last two bosses. If your only goal is the set bonus, you do not need a full-clear carry. Four targeted kills get you there, and the Catalyst lets you convert a normal-track piece every week to backfill the slot that refuses to drop. Hold your first one or two Catalyst charges until you know which slot is your weak link — converting blind is how people end up with two chest pieces and no legs.

The trinkets that decide whether a boss is worth repeating

Trinkets are the real reason to learn this loot table. Across the tier, two or three stand out far enough that sims will tell almost every spec to keep farming the boss that drops them long after the rest of the slot is settled.

The goblin-tech trinkets in this raid lean heavily on burst and on-use windows that line up with two-minute cooldowns, which is exactly what pushes them above the dungeon and crafted alternatives. For most DPS, a single on-use damage trinket from this raid is worth more than two or three armor upgrades elsewhere. That changes your priority: a boss that drops a best-in-slot trinket for your spec jumps the queue even if it's deeper in the instance.

Check your spec's current sim on Bloodmallet or Raidbots before you commit. The trinket landscape shifts with every balance patch, and a trinket that's top-three in week one can fall off after a tuning pass. The boss is worth repeating only as long as the item still sims ahead of what you already have equipped.

Boss-by-boss priority

Opening bosses: tier and a clean entry trinket

The first two or three encounters are the most reliable value per pull. They drop early-slot tier tokens and at least one accessible trinket, and they're the bosses a fresh group can clear without coordination meltdowns. This is where your weekly lockout should always start. If you're buying any time here, it's the cheapest, lowest-risk part of the raid to carry — but it's also the part you can pug most easily, so most players should just run it.

Mid-instance: the gear-check wall

The middle of Liberation of Undermine is where item level starts to matter and mechanics get punishing for undergeared groups — think stacking debuffs, add waves, and movement that wipes pugs that haven't gemmed or enchanted. These bosses hold key tier slots (hands and legs) plus solid secondary trinkets and rings. They're worth more loot than the openers, but they're also where pug progression stalls for weeks. If there's one stretch of this raid where a carry is a sensible time-for-money trade, it's here — not because the bosses are impossible, but because clearing them yourself often means dozens of failed pug attempts to get four working kills. Buying a mid-instance carry skips the part that wastes the most evenings.

Late bosses: weapons and the high-end trinket

The last two or three encounters stop dropping tier and start dropping the items that define your character's ceiling: weapons and the raid's standout on-use trinket. A weapon upgrade here is frequently the single largest DPS or HPS jump available to you all patch — bigger than any two tier pieces combined. That makes these the bosses worth chasing on heroic and then mythic, and the ones where a carry pays off most if you're short on a reliable group, because they're also the hardest to pug to a clean kill.

Chrome King Gallywix: the final boss

Gallywix is a multi-phase fight with a transition into mech and energy-bomb mechanics that demand the whole raid execute, not just the tanks. His loot pool is the best in the instance per slot — top weapons, the premium trinket, and the highest base item level. It's also the kill that most pug groups never see on mythic. For the mount, the title-adjacent prestige, and the highest drops, a Gallywix carry is the most defensible single purchase in the tier. For everyone else, he's a long-term goal you build toward as your group's item level catches up.

A simple priority order to follow

  • Week one to three: farm openers and mid-bosses for tier. Build your 2-set, then 4-set. Convert with the Catalyst only to fill your missing slot.
  • Once 4-set is online: shift focus to whichever boss drops your top-simming trinket and your weapon. These outvalue raw item level.
  • Carry decisions: skip carries on the openers (pug them), consider one on the mid-instance wall if pugs keep stalling, and save the real money for a late-boss or Gallywix carry where the loot ceiling and the kill difficulty are both highest.

Played honestly, most of Liberation of Undermine is worth clearing yourself — the openers are easy value and the gear-up curve is the fun part. The two places where time-for-money makes sense are the mid-instance wall that eats pug nights and the final-boss kill that pugs rarely complete. Everything between those, just play out.
