Liberation of Undermine Overview

Welcome to the Liberation of Undermine overview. The second new raid in WW was introduced in Patch 11.1: Undermine(d). In the heart of the Goblin Trade Empire lies Undermine, a bustling capital that showcases the ingenuity and creativity of Goblins as masters of technology. As you traverse this chaotic city, you ally with various Goblin cartels to face incredible challenges in this thrilling Season 2 raid.

This 8-boss raid takes you through the vibrant streets of Undermine, culminating in a showdown with the notorious former Horde leader, Gallywix. His extravagant hideaway, Gallagio, is filled with dark secrets, mechanized monstrosities, and deadly Goblin gadgetry.

Gallywix, last seen fleeing Orgrimmar at the end of Battle for Azeroth and briefly negotiating with Cartel Xy in Tazavesh, the Veiled Market during Shadowlands, now returns with sinister plans. The raid offers explosive encounters as you confront his schemes and the mechanized horrors of Undermine.

Liberation of Undermine Location

To access the Liberation of Undermine location, you’ll need to travel to one of the faction capitals, either Orgrimmar or Stormwind. In these cities, you can find Nexus-Lord Donjon Rade V, who offers a teleport directly to the raid entrance.

The raid is located in the heart of Undermine, the bustling capital of the Goblin Trade Empire. While Nexus-Lord Donjon Rade V provides convenient teleportation, you’ll find the entrance to the raid marked by Goblin-themed structures and surrounded by vibrant, mechanized surroundings that reflect the ingenuity of the Goblins.

Ensure that your raid group is prepared before teleporting, as this chaotic city raid promises an explosive series of encounters filled with mechanized monsters and Goblin gadgetry.

The raid consists of several small maps, the main one you can see below. This is the Liberation of Undermine map for all of the known boss encounters. 

 

As for the Liberation of Undermine entrance itself, it will presumably be available in the adjacent zone, but for the testing a portal is provided in both capital cities for quick access.

Liberation of Undermine Bosses

The raid features a total of 8 Liberation of Undermine bosses, each embodying the chaotic and inventive nature of Goblin ingenuity. Below is a list of the bosses you will face as you navigate the mechanized streets of Undermine:

1. Stix Bunkjunker
2. Vexie and the Geargrinders
3. Cauldron of Carnage
4. Rik Reverb
5. Sprocketmonger Locknstock
6. One-Armed Bandit
7. Mug’Zee, Heads of Security
8. Chrome King Gallywix (Final boss, not available during initial testing)

This Liberation of Undermine boss order is not final, although the first encounter will not be changed. Each boss offers unique challenges and mechanics, ensuring that this raid will keep your group on its toes from start to finish. Stay sharp and prepare for Goblin-inspired chaos!

Liberation of Undermine Boss Tactics

This section of the guide is dedicated to Liberation of Undermine tactics, offering insights into the encounters you will face within this explosive raid. While detailed strategies for each boss are provided in their respective sections below, this overview serves as a quick reference for players preparing to take on the challenges ahead.

Keep in mind that this is not a comprehensive Liberation of Undermine bosses guide.

So, if something doesn’t work exactly as described, chances are that the devs rolled out a secret update. Either way, everything will be updated in time.

If any particular fight proves too difficult, remember that professional assistance, like Liberation of Undermine Raid Boost, is available through trusted services. With expert players on your side, you can clear encounters efficiently and secure top-tier loot without the stress of trial-and-error gameplay.

Stix Bunkjunker Strategy (based on PTR)

Let’s start this Liberation of Undermine raid walkthrough with the first and only (so far!) boss encounter. The Stix Bunkjunker encounter is a multi-phase battle focused on ad management, positioning, and coordinated execution of mechanics. In here, we outlined the critical aspects of the fight to help you and your team successfully navigate this unique challenge.

Phase 1: Mechanics Overview

The fight begins with a straightforward single-target phase where tanks should position Stix Bunkjunker centrally, allowing for easy access by melee DPS and healers. Watch out for Incinerator, which requires players to spread out to avoid overlapping damage zones. Early in the phase, players are introduced to the ball transformation mechanic and bomb management.

• Ball Transformation: Several (six) players are chosen to transform into balls aka Rolling Rubbish. As a ball, you must:
  
  • Roll over small garbage piles to grow larger.
  • Progress through small, medium, and large ball stages by collecting garbage.
  • Once fully charged, collide with the boss to deal damage or with a bomb to neutralize it.
• Bomb Management: Large bombs periodically spawn and must be neutralized by players in their big ball state. Tanks typically handle the first bomb, while another designated player deals with additional bombs in later phases. Failure to neutralize bombs results in a raid wipe.

Phase 2: Ad Management and Overdrive

As the fight progresses, Territorial Bombshell adds tethered to garbage piles spawn. These must be addressed quickly:

• Players free the adds by reducing their health to 75%, breaking their tether, and then killing them within 30 seconds.
• Failing to kill them in time causes explosions, leading to heavy raid damage.

Players in the ball state must avoid rolling over tethered adds to prevent accidental detonations.

During Overdrive, Stix Bunkjunker becomes untargetable and flies into the air, dealing raid-wide damage and unleashing abilities like Trash Compactor, which knocks players back. Position carefully to avoid being knocked into hazards. After Overdrive, the boss returns with increased attack speed and more frequent bomb spawns, escalating the fight's intensity.

Strategy Summary

To secure victory, clear coordination and role assignment are critical:

1. Assign tanks and specific players to manage bombs during both phases, ensuring no bomb is left unattended.
2. Focus on efficient ad management by prioritizing Territorial Bombshells and keeping them under control. Use cleave damage to take down clusters quickly.
3. Healers must monitor raid-wide damage during Overdrive and the stacking debuff caused by ignited garbage piles.
4. DPS should focus on maximizing boss uptime during calm moments while swiftly switching to adds when required.
5. Avoid igniting garbage piles with Incinerator Circles, as this increases the difficulty of bomb management and adds additional pressure to the group.

This strategy was written based on the Patch 11.1 PTR raid preview. So, there’s a good chance that some of these values and details about the fight will change. When this happens, we’ll update the guide, so that you have the latest and most accurate info on your hands.

Plus, additional boss encounters will be available at a later date according to the established testing schedules. Therefore, as the new boss encounters become available, we’ll add them into this guide, until all eight encounters are covered. So, stay tuned for that!

 

Sprocketmonger Lockenstock Strategy (based on PTR)

Sprocketmonger Lockenstock is the fifth boss in Liberation of Undermine, offering a chaotic and mechanically intense encounter. Featuring conveyor belts, explosive mines, and escalating weapon mechanics, this fight challenges players to manage overlapping hazards and maintain precision. Below is a complete guide to help your team navigate this encounter. First, we're going to take a look at the arena hazards, because in  this fight its important to keep those in mind.

• Conveyor Belts: The arena features multiple conveyor belts:Central belts with traps and holes. Avoid these as they can knock players back or even kill them outright.
  
  • Side belts that may serve as safe zones during specific phases.
    
  • Holes: Hard to spot, these can cause immediate death or disrupt your positioning. Avoid them to stay in the fight.
• Mines: Sprocketmonger periodically places four mines on the ground.These mines must be detonated one at a time to avoid raid-wide damage.
  
  • On Heroic, players must be organized into groups to stagger mine detonations, avoiding multiple explosions at once.
    
  • Failure to coordinate detonations can result in overlapping debuffs and unnecessary deaths.

These are the things to keep in mind while fighting Sprocketmonger. But, that's not all. This boss has a slew of abilities that he will use at different stages of the battle.

Strictly speaking, the boss has two primary phases that repeat with escalating mechanics as the fight goes on. But, we've decided to break down the whole thing into smaller, more digestible parts to explain each mechanic and the way it escalates clearly. Just know that the whole structure of this boss fight is more cyclical, with increasing complexity rather than distinct, separate phases.

Phase 1: Setting the Stage and Managing Mines

As the fight begins, players must spread out and establish positions to handle Foot Blaster Mines effectively. The boss places mines that need to be detonated strategically to avoid excessive damage. Divide the raid into groups, assigning each group to a mine to ensure staggered detonations. This prevents the stacking debuff from overwhelming the group.

Stay away from the central conveyor belts during this phase. These are littered with traps and holes that can knock players into dangerous areas or even result in instant death if mishandled. Use the edges of the room for safe positioning and focus on staying mobile to avoid other hazards.

Tanks should prepare for the Tank Bomb Mechanic, which requires them to move away from the group while under the effects of a slowing debuff. Coordinate taunt swaps to mitigate the damage effectively.

Phase 2: Conveyor Belt Survival

At this point, the boss knocks players toward the central conveyor belts, electrifying them and forcing movement. Use the edges of the belts to avoid damage and keep an eye on debuff zones that can reduce healing and cause dazes. The belts also feature lightning hazards that players must dodge while staying mobile.

This phase is primarily about survival. Healers should focus on keeping the raid healthy while players reposition and avoid hazards. Any downtime can be used to prepare for the next phase or recover from earlier mistakes.

Phase 3: Weapon Mechanics and Escalation

The boss begins activating weapon systems, including Beam Weapons, Rocket Barrage, and Magnetic Pull. Each of these introduces its own challenges:

1. Beam Weapons: Large laser beams sweep across the room, requiring players to pre-position in safe zones. Enhanced beams in later phases will cover more area, making preemptive movement crucial.
2. Rocket Barrage: Rockets land randomly, dealing AoE damage on impact. Awareness is key, as these can be hard to see, especially during overlapping mechanics.
3. Magnetic Pull: Magnets appear, pulling players toward electrified conveyor belts. Use personal movement abilities to resist the pull and avoid being dragged into hazards.

Tanks will continue to handle the bomb mechanic, moving away from the group as needed. Communication during this phase is critical to ensure players handle their assigned responsibilities and maintain positioning.

Phase 4: Overlapping Chaos

As the fight progresses, mechanics begin to overlap, creating periods of intense raid-wide pressure. Mines, beams, rockets, and magnets may all be active simultaneously, testing the raid’s coordination and adaptability. This phase demands precise execution:

• Focus on survival above all else. Moving out of hazards and avoiding overlapping mechanics should take priority over maximizing damage.
• Use raid cooldowns to mitigate burst damage during particularly heavy overlaps.
• Keep movement abilities on cooldown for quick repositioning, especially when magnets and beams overlap.

Healers should be prepared to respond to spikes in damage, and players must take personal responsibility for dodging hazards to reduce strain on the raid.

Phase 5: Conveyor Knockback and Final Push

During the final phase, the boss uses an enhanced version of the Conveyor Survival Mechanic, electrifying the belts and knocking players back. Players must navigate the belts carefully, using the edges for faster and safer movement while avoiding lightning zones.

The goal here is to stay alive and return to the boss quickly to resume dealing damage. Melee players can utilize the side belts to maintain uptime, but ranged players should focus on positioning in safe zones to free-cast while dodging hazards.

The boss enhances previous mechanics during this phase, with larger beams and faster rockets adding complexity. Maintain discipline and avoid unnecessary deaths to secure victory.

The One-Armed Bandit Strategy (based on PTR)

The One-Armed Bandit is the 6th boss fight, introducing unique mechanics involving casino-themed elements such as slot machine mechanics, casino chips, and tokens. Players must manage their priorities carefully while dealing with overlapping mechanics, which ramp up in difficulty throughout the encounter. First, we'll break down the boss' abilities and then move to tactics and strategy broken down into phases.

Ability	Description	Counter/Strategy
Casino Tokens	Rolls blue casino chips that stun players hit for 8 seconds but grant a haste buff if avoided properly.	Stand close enough to avoid the stun and receive the haste buff or destroy them to avoid risks.
Slot Machine Adds	Three types of adds spawn at full energy: Coin Assistant, Shock Assistant, and Flame Assistant. Each drops a token upon death.	Quickly nuke the adds and collect two unique tokens to deposit into the boss.
Token Combinations	Depositing tokens into the boss triggers specific mechanics depending on the combination.	Rotate through unique token combos to manage mechanics and avoid repeating a combo.
Shocking Fields	Tank mechanic that leaves electric fields on the ground with each tank hit.	Tanks can clear fields by activating coils, which spawn additional mechanics.
Beam Coil Mechanic	The boss spawns a coil and creates a deadly beam between the coil and itself.	Avoid the beam at all costs; players marked for beams must position carefully to avoid wiping the raid.
Fixating Bomb Adds	Adds spawned from specific token combos that fixate on players and explode if not killed.	Cleave the adds quickly and stay away from their target paths.
Phase 2 Mechanics	In the final phase, the boss randomly chooses mechanics while applying heavy raid-wide damage.	Prioritize survival and damage output to defeat the boss before reaching enrage.

Phase 1: Add Management and Token Coordination

The fight begins with the boss cycling through its core mechanics, including the adds, tokens, and casino chips. Coordination is key to surviving this phase.

Managing Adds and Tokens

• At full energy, the boss spawns three adds: Coin, Shock, and Flame. Each add drops a corresponding token when defeated.
• Players must collect two tokens and deposit them into the boss using an extra action button.
• Each combination of two tokens activates a unique mechanic for the raid to handle. The six possible combinations are:
  • Coin + Shock: Summons a coil that applies a buff or debuff.
  • Coin + Flame: Spawns fixating bomb adds that explode on contact.
  • Shock + Flame: Summons CC-able fixating adds for easy control.
  • Coin + Coin, Shock + Shock, or Flame + Flame: Repeating a combination results in an instant wipe.

Casino Chips

The boss throws casino chips, creating a high-risk, high-reward mechanic:

1. Risk: Chips stun anyone hit for several seconds, causing significant raid disruption.
2. Reward: Standing close to a chip without being hit grants a haste and damage buff.

Players must decide whether to shoot the chips into the raid for buffs or safely direct them toward the walls to minimize risk.

Tank Mechanics

The tank faces periodic mechanics that create electric fields. Each electric field persists, reducing available space over time. Tanks can clear these fields by activating coils with an extra action button, but doing so triggers additional mechanics tied to the coil type.

Phase 2: High-Stakes Finale

As the fight progresses, the boss intensifies its mechanics, culminating in an enrage phase.

Escalating Mechanics

The boss begins randomly selecting previously activated mechanics, combining them with ongoing raid damage:

• Beam Coils: Coils connect to the boss with deadly beams that must be avoided.
• Fixating Adds: Adds chase players, requiring quick coordination to handle safely.
• Scattered Payout: Raid-wide damage increases rapidly, pushing healers to their limits.

The randomness of ad spawns and token combinations makes each pull unpredictable.

By Phase 2, electric fields from the tank mechanic cover much of the arena. Players must navigate these fields while handling beams, casino chips, and other mechanics, ensuring they maintain safe zones for movement.

Soft Enrage

As the boss approaches the final moments, it enters Scattered Payout, causing extreme raid-wide damage. The fight becomes a DPS race to kill the boss before the final mechanic, which results in an instant wipe.

Mug'Zee: Heads of Security Strategy (based on PTR)

Mug'Zee is a two-headed enforcer guarding the penultimate chamber of the raid. This encounter is a dynamic and chaotic fight that splits mechanics across two modes, determined by which side of the room the raid favors. Each head brings its unique set of challenges, requiring precise coordination, positional awareness, and adaptability to overcome. Mug represents explosive chaos, while Zee introduces icy discipline, culminating in an intense final phase where both sets of mechanics overlap.

Phase 1: Mug’s Explosive Chaos

The encounter begins with Mug’s mechanics dominating the battlefield. The raid must focus on managing mines, soaks, and tank mechanics.

Mines and Cluster Bombs:

Mug periodically spawns Unstable Crawler Mines that fixate random players. To deal with these, the fixated player must intentionally detonate the mine by allowing it to reach them. When detonated, the mine spawns Cluster Bombs, which create multiple small soak zones that must be covered by the raid.

• Assign players to handle specific mines or designate a high-mobility tank or DPS to detonate multiple mines if possible.
• All cluster bomb soak zones must be covered promptly, as even one missed soak can cause devastating raid-wide damage.

Intercept Beam (Tank Mechanic):

Mug targets a random player with a high-damage beam. The tank must intercept the beam by stepping in front of the targeted player, reducing the damage they take.

• Ensure the targeted player stops moving to give the tank time to position correctly.
• The player hit by the beam gains a bomb debuff that must be dropped away from the group.

Gatling Spray: Mug unleashes a frontal cone attack. The boss must be faced away from the raid at all times to avoid unnecessary damage to the group. Transition Preparation: Clear as many mines and cluster bombs as possible before transitioning to Zee’s side to reduce leftover mechanics that could complicate the next phase. Players should begin pre-positioning near the center of the room once Mug reaches 50% energy.

Phase 2: Zee’s Icy Discipline

Switching to Zee introduces entirely different mechanics that require coordination and controlled movement.

Jail Walls and Add Management:

Two players (one melee, one ranged) are selected to soak Jail Wall Zones, which create line-of-sight barriers. These zones trap the players inside with two adds that must be defeated to escape.

• Assign high-DPS players to these roles to ensure quick add kills.
• Players outside the jails focus on managing external mechanics while the jailed players handle the adds.

Ice Spears:

Players outside the jails are targeted with Ice Spears that must be redirected to hit barriers (walls, leftover bombs, or jails) to avoid lethal damage.

• Targeted players should plan their movement to ensure the spears hit valid barriers while avoiding group members.
• If barriers are used efficiently, spears can also contribute to managing leftover mechanics, such as mines or bombs.

Golden Drip (Tank Mechanic):

Tanks deal with a debuff that drops harmful golden pools on the ground.

• Kite Zee around the room to drop pools in low-traffic areas, ensuring they don’t obstruct group movement or create danger zones during transitions.

After handling two cycles of Zee’s mechanics, the group must transition back to Mug. Clear any golden pools near the center of the room to maintain a safe path during the transition.

Final Phase: Combined Onslaught

In the final phase, Mug and Zee combine their mechanics, creating an intense overlap of all prior abilities. Coordination is key to survival.

• Mines and Cluster Bombs from Mug’s side will overlap with Zee’s Ice Spears and Jail Walls. Assign clear roles to handle each mechanic and avoid duplication of efforts.
• Tanks must continue managing Golden Drip while ensuring Intercept Beam is properly mitigated.
• Healers should stagger cooldowns to counter escalating raid-wide damage caused by the overlap of Mug’s and Zee’s mechanics.
• DPS players should maximize output while prioritizing survival, as the phase has a hard enrage.

This phase demands precise execution of mechanics learned in the first two phases, with little margin for error. Assign responsibilities clearly and focus on surviving until the boss is defeated.
