How many bosses are in Undermine
Liberation of Undermine raid features eight exciting encounters with the following bosses:
Vexie and the Geargrinders
Vexie Fullthrottle and her gang strike fear into anyone unfortunate enough to cross their path. Answering Gallywix’s call for backup, they’ve arrived in Undermine to settle an old debt—leaving behind plenty of chaos and grease stains in the process.
Cauldron of Carnage
Undermine is no stranger to intense battles, but none compare to the ongoing feud between Torq the Tempest, a galvanic gorilla, and Flarendo the Furious, a molten mechasaur. Their explosive showdown threatens to split the city in two, and only the bravest will dare to intervene.
Rik Reverb
Rik Reverb lives for the sound of explosions, fireworks, and, most of all, his own voice. From his airborne sonic resonator, he serves as Gallywix’s top hype man, mesmerizing Undermine’s citizens with dangerously addictive beats.
Stix Bunkjunker
Garbage disposal is an essential service—at least, that’s what Stix Bunkjunker wants everyone to believe. He and his crew have been “cleaning up” Undermine for years, finding creative ways to eliminate anything (or anyone) deemed unnecessary.
Sprocketmonger Lockenstock
A brilliant yet ruthless inventor, Sprocketmonger Lockenstock is always pushing the boundaries of innovation—often at the expense of safety and ethics. His never-ending quest to cut costs and maximize efficiency makes Undermine the perfect testing ground for his latest contraptions.
The One-Armed Bandit
The pride of Gallywix’s Gallagio, this mechanical enforcer ensures fair play—though its definition of “fair” remains a mystery. Those caught breaking the rules won’t get a second chance, as its punishments are swift, brutal, and unmistakable.
Mug’Zee, Heads of Security
Born inseparable, the two heads of Mug’Zee rest atop a massive ogre enforcer tasked with keeping order at the Gallagio. Recently reassigned, Mug’Zee now stands guard over the casino’s most restricted areas, ensuring no one gains unauthorized access.
Chrome King Gallywix
After retreating to his fortress within the Gallagio, Jastor Gallywix has been hard at work on something powerful and deadly. Whatever his latest creation is, it’s designed to obliterate anyone who dares to challenge him.
Vexie Fullthrottle boss guide
Vexie is the first enemy we will start this Liberation of Undermine bosses guide with. Recommended Bloodlust/Heroism timing: Second phase.
Phase 1
On Normal difficulty, the fight revolves around managing Protective Plating, handling Biker adds, and executing proper Tank swaps. On Heroic difficulty, the challenge intensifies with the addition of a new mechanic, Spew Oil, and extra debuffs that complicate positioning and movement.
Below is a breakdown of Vexie’s abilities and the best strategies to counter them.
On Normal difficulty:
| Ability | Description | Tip |
|---|---|---|
| Protective Plating | Plating has 4 stacks and lets the boss gain energy. | This is the main mechanic of the whole boss battle. All platings must be removed within two minutes with the next ability mechanic. Otherwise, the boss reaches 100 Energy and wipes the raid with Unrelenting CAR-nage. |
| Call Bikers | The boss summons adds to the arena. These adds charge into random players and leave a bike upon death. | Since adds spawn on the opposite side of the arena, tanking the boss near the edge makes them spawn in almost same place. Kill bikers adds and use their bikes to remove Protective Plating from the boss. Click on the bike to hop on, aim the boss, and use the first action button to send the bike into the enemy. |
| Tank Buster | This ability debuffs the hit player to receive 200% more damage from the next Tank Buster. | Swap Tanks after every Tank Buster cast. |
| Incendiary Fire | The boss creates flaming zones under the marked players every 0,5 seconds. | Stutter-step damaging zones and slightly move away from the raid. |
On Heroic difficulty, Vexie gains an extra ability. Also, her existing ones also apply debuffs as detailed below:
| Ability | Description | Tip |
|---|---|---|
| Protective Plating | Plating has 6 stacks and lets the boss gain energy. | No change. |
| Call Bikers | No change. | No change. |
| Heroic: Spew Oil | The boss marks a few players with purple circles and creates Oil Slicks under them after a few seconds. | Leave Oil Slicks on the edges of the arena to avoid these zones at places where they can be uncomfortable to handle. Make sure not to send bikes from adds through Oil Slicks. Otherwise, they will be stuck and won’t hit the boss and remove its Protective Plating. Players with Incendiary Fire effect must clear Oil Slicks by running into them. |
| Tank Buster | Heroic: Tank Buster leaves an Oil Slick under the boss. | Heroic: Keep the boss to the edges of the arena for Oil Slicks not to appear in bad places. |
| Incendiary Fire | The boss creates flaming zones under the marked players every 0,5 seconds. These zones remove Oil Slicks. | Bite damaging zones to remove as many Oil Slicks as possible. |
Phase 2
In both Normal and Heroic difficulty, Phase 2 begins once all Protective Platings are removed. This phase is a short but crucial damage window where you should maximize your damage output while preventing the boss from regaining its defenses:
| Ability | Description | Tip |
|---|---|---|
| Mechanical Breakdown | Boss reaches this phase after all Protective Platings are removed. Lasts 45 seconds. | The boss takes 100% more damage. This is an excellent opportunity to use your strong cooldowns, including Bloodlust/Heroism. |
| Pit Mechanics | The boss calls for Pit Mechanics adds to appear. When they reach the boss, they start to Repair its Protective Plating. | Make sure to CC or quickly AoE cleave the adds before they reach the boss. They will disappear after the phase is over, so CCing might be the best solution to avoid wasting damage resources. |
Cauldron of Carnage boss guide
Here is Cauldron of Carnage, Liberation of Undermine boss, guide. Here, we will mention all their abilities and strategies for conquering them. Recommended Bloodlust/Heroism timing: Pull.
Phase 1
This whole phase is concentrated on splitting the raid into two groups for separate battling with Flarendo and Torq.
| Ability | Description | Tip |
|---|---|---|
| Blistering Spite / Galvanized Spite | Flarendo / Torq applies Blistering / Galvanized Sprite DoT. This debuff stacks. | Divide the raid into two groups. Keep the bosses on the opposite sides of the arena. Swap groups after every second phase. Raised Guard is another reason to not bring them together as they start receiving less damage. |
| King of Carnage | The last remaining boss gets a stacking damage increase. | Make sure to defeat both Flarendo and Torq at the same time. |
Flarendo group
On Normal difficulty, Flarendo raid group has to concentrate on performing Scrapbomb mechanic and bringing Blastburn Roarcannon out of the raid and away from the bomb.
| Ability | Description | Tip |
|---|---|---|
| Scrapbomb | Flarendo creates a bomb that deals heavy damage to the raid. | Share the bomb’s damage together. |
| Blastburn Roarcannon | Flarendo focuses on the random player and starts casting a deadly beam after some preparation. | Move the laser path away from the raid and the bomb. |
| Eruption Stomp | Flarendo deals high damage to the Tank and sends it into the air. | Tanks have to use defensives to survive this ability. Healers might need to use their strong healing cooldowns. |
On Heroic difficulty, the Scrapbomb mechanic is more complicated.
| Ability | Description | Tip |
|---|---|---|
| Scrapbomb | Heroic: The bomb creates a Molten Pool after explosion. | Heroic: Make sure to move to the edge of the arena before the explosion and run away from the fire zones after it. |
| Blastburn Roarcannon | No change. | No change. |
| Eruption Stomp | No change. | No change. |
Torq group
On Normal difficulty, Torq raid group has to concentrate on moving as little as possible even while dodging.
| Ability | Description | Tip |
|---|---|---|
| Static Charge | Players fill the Static Charge bar when moving and reduce it when standing. When the bar is filled, Static Discharge stuns the player. | Try moving as little as possible. Stutter-step if you need to dodge anything. |
| Lightning Bash | Torq smashes the Tank, dealing all unmitigated damage to the raid. | Use defensives to reduce the damage to the raid. |
On Heroic difficulty, the penalty for moving becomes worse, and players have to dodge one more mechanic.
| Ability | Description | Tip |
|---|---|---|
| Static Charge | Heroic: Static Charge stuns all players within 10 yards when the bar fills. | Try moving as little as possible. Stutter-step if you need to dodge anything. |
| Heroic: Voltaic Image | Torq summons images that chase players and deal damage and create a hazardous zone on contact. | CC the images to avoid unnecessary running. |
| Lightning Bash | No change. | No change. |
Phase 2
The boss starts the Phase 2 when it reaches 100 Energy. If the raid successfully survives the phase, both Flarendo and Torq return to Phase 1.
| Ability | Description | Tip |
|---|---|---|
| Colossal Clash | Bosses move to the center of the arena, deal heavy damage to the raid, and start casting Zapbolts and Fiery Waves onto players. Damage to the raid is increased by 15% with each Colossal Clash. | Use defensives to survive the raid damage. Avoid swirlies from Fiery Waves and lightnings from Zapbolts. |
Rik Reverb boss guide
Rik Reverb is the third boss in this raid. Here are some Liberation of Undermine tips and tricks to defeat this boss with no issues. Recommended Bloodlust/Heroism timing: Pull.
Phase 1
During this phase, on Normal difficulty, players have to concentrate on both damaging the boss and completing the Amplifiers mechanic.
| Ability | Description | Tip |
|---|---|---|
| Amplification! | The boss summons Amplifiers next to his arena. Amplifiers create Noise Pollution and Resonant Echoes that become deadlier with every new Amplifier. When the Amplifire reaches full energy, it wipes the raid with Haywire. | Make Amplifiers lose their power by activating them and causing Lingering Voltage. Choosing ranged classes to perform this mechanic is the best choice, since these players can keep dealing damage to the boss while activating Amplifiers. Healers have to pay extra attention to the health of players who perform this mechanic. |
| Faulty Zap | Rik marks random players with an AoE zone around them and damages anyone inside. | Move zones out of the raid. |
| Sonic Blast | Tank combo that leaves a debuff increasing damage from the next Sonic Blast by 100%. | Swap Tanks after the debuff expires on the resting Tank. Other players should avoid getting hit by this ability, so make sure to move away from the boss’s face. |
On Heroic difficulty, one ability is added, making the raid quickly split their damage to destroy barrels.
| Ability | Description | Tip |
|---|---|---|
| Amplification! | Heroic: Lingering Voltage leaves a stacking DoT on players | Change players who activate amplifiers. |
| Faulty Zap | No change. | No change. |
| Sonic Blast | No change. | No change. |
| Heroic: Sparkblast Ignition | The boss drops five barrels to the arena. Once they explode, they wipe the raid with Grand Finale. | Destroy barrels within 15 seconds to avoid a wipe. Dealind damage to barrels increases your movement speed by 10% and Haste by 2%. Stacks up to three times. |

The boss enters Phase 2 at 100 Energy. After the Hupe Hustle is over, Rik returns to Phase 1.

Phase 1
During this phase, on Normal difficulty, players have to collect garbage and focus adds to defeat the boss.
| Ability | Description | Tip |
|---|---|---|
| Electromagnetic Sorting | When the boss reaches 100 Energy, he creates small and large Garbage Piles. A few players have to roll at the arena and collect the trash by pathing through it. Rolling over another player stuns it. | Fill the bar by rolling over four small and then four large Garbage Piles or Scrapmaster adds. Don’t roll through the boss when the bar is not full. Make one cleaning player roll through all Discarded Doomsplosives once it fills the bar to remove them. Other cleaning players can roll through adds first, and then through the boss for extra damage to both. Heroic: Avoid rolling through Territorial Bombshells. |
| Incinerator | The boss marks random players with an AoE zone. Garbage Piles get on fire on impact from this spell and start dealing damage to the raid. At least one Garbage Pile will be set on fire after each cast. | Move zones out of the raid and away from Garbage Piles. |

Kill adds ASAP. |
| Demolish | The boss performs Tank combo that applies a debuff increasing all damage taken by 100%. | Swap Tanks after every Demolish. |
| Heroic: Territorial Bombshell | Three Territorial Bombshells are added to the large Garbage Piles in total. Rolling over the bomb or leaving it undestroyed makes it explode. Surviving more than one is almost impossible. | Focus bombs and drop them below 75% to detach them from Garbage Piles. Avoid rolling onto bombs and destroy them before they explode. |

Phase 1
During this phase, on Normal difficulty, players have to dodge electrified zones on the arena and dodge various projectiles.
| Ability | Description | Tip |
|---|---|---|
| Wire Transfer | Boss arena has four static spaces and three main conveyors. Two segments are electrified and deal damage. Conveyors remain safe for most of the fight. From time to time, electrified segments switch. Each boss fight has the same changing pattern. | Move to segments that are not electrified. Check a schematic picture below this phase to learn more about patterns. |
| Screw Up | Boss marks a random player and drills start to appear under it every 1,5 seconds. | Stutter-step away from the raid. |
| Gravi-Gunk and Pyro Party Pack | Boss’ attacks apply Gravi-Gunk to the target, increasing damage taken and slowing the target. Pyro Party Pack attaches a bomb to the current Tank. After six seconds, the bomb detonates, dealing damage to the raid. | Change Tanks after five stacks of Gravi-Gunk or after Pyro Party Pack cast. Move the bomb away from the raid to deal less damage to the raid. |
| Sonic Ba-Boom | Boss damages the raid and applies DoT debuff to all players. | You might want to use your strong healing cooldowns during this spell’s impact. Players can also use their defensives to lose less health. |
| Activate Inventions! | All inventions on conveyors are activated. After the first second phase, Blazing Beams become Jumbo Void Beams with larger lasers. After the second second phase, Rocket Barrage becomes Void Barrage, dealing AoE damage on impact. | Dodge lasers from Blazing Beams on the left conveyor and rockets from Rocket Barrage on the right conveyor. Move away from magnets on the central conveyor, not to get stunned. |
| Heroic: Foot-Blasters | Boss spawns bombs in the arena. Bombs are triggered by stepping on them or by electricity from the segment. 12 bombs in total appear during one phase. | Detonate bombs one by one with different players.

- Bombs – locations of three-pack of Foot-Blasters on Heroic difficulty.
- Red rectangle – arena entrance.
Phase 2
Spocketmonger enters Phase 2 after reaching 100 Energy and returns to Phase 1 after Beta Launch mechanic.
| Ability | Description | Tip |

Phase 1
| Ability | Description | Tip |

| Scatterblast Canisters | Boss performs a cone frontal at the current Tank, applying absorb heal to all players hit. | Split the raid into two groups and share frontal damage one by one. Switch Tanks after each cast. Heal through absorb. |
| Big Bad Buncha Bombs | Gallywix uses various bombs against the raid that apply a stacking DoT to any player hit. Bad Belated Boom: Bombs that create a zone on the floor and deal heavy damage to players hit. Sapper’s Satchel: Marks random players and explodes in a circle around them. Zagging Zizzler: Fires damaging projectiles. Heroic: One 1500-Pound “Dud” bomb that wipes the raid if it explodes after 15 seconds. | Run away from Bad Belated Boom zones not to get hit.

Activating it deals heavy damage to the Tank and knocks it back. |
| Suppression | Boss creates damaging zones all over the arena. | Dodge swirlies. |
| Venting Heat | Gallywix deals heavy damage to the raid and applies DoT to all players. | Use defensives or strong healing cooldowns. |

During the Tank swap or after reaching 10 stacks, all stacks are consumed and the boss deals heavy damage, applying a stacking DoT (damage increases based on consumed stacks). | Swap Tanks in time and use defensives. Gallywix doesn’t move. Make sure to leave at least one Tank in melee at all times to avoid sudden deaths. |
Phase 2
Boss reaches this phase at 100 Energy. All abilities from the first phase remain and new ones are added.
| Ability | Description | Tip |
|---|---|---|
| Giga Coils | Gallywix activates one out of four Giga Coils on the arena that pulsate and deal damage. Giga Blast deals damage in a line and increases damage from Giga Coils. | Bring Giga Bomb to Giga Controls to stop the boss. |
| Darkfuse Technician | The add drops a Giga Bob that can destroy Giga Controls, making Giga Coils inactive for the rest of the fight. Destroyed Giga Coils’ quarters of the arena become electrified and start dealing damage. | Kill the add ASAP and deliver Giga Bomb to Giga Controls (lights that indicate which Giga Coil is going to be activated) to stop the Coil from wiping the raid. The bomb can be thrown to save time. |
| Giga Blast | Gallywix channels a laser beam. | Dodge the laser and move Giga Bomb away from it. |
| Fused Canisters | Boss marks random players with the spell, dealing damage and applying heal absorb. If less than two players handle one Fused Canister, the whole raid gets heal absorb. | Make sure that at least two players handle each Fused Canister. |
| Sharpshot Sentry / Darkfuse Wrenchmonger | Gallywix summons adds to the arena. | Sharpshot Sentry’s casts must be interrupted, and Darkfuse Wrenchmongers need to be aggroed by Tanks. Heroic: Darkfuse Wrenchmongers gain an enrage buff that slows them. It can be removed or used to kite these adds. |
Intermission
The boss starts intermission at 50% health.
| Ability | Description | Tip |
|---|---|---|
| Cratering | Gallywix slams the arena with Cratering, killing anyone on impact, and gets a massive shield, blocking interrupts. Heroic: Radiant Electricity spawns damaging lightnings during the intermission as well. | Break through the shield to interrupt TOTAL DESTRUCTION!!! cast. Heroic: Dodge Radiant Electricity lightnings. |
Phase 3
Gallywix enters Phase 3 after the Intermission shield is broken and TOTAL DESTRUCTION!!! cast is interrupted. On normal difficulty, players will have to face a deadlier version of Phase 1 mechanics.
| Ability | Description | Tip |
|---|---|---|
| Bigger Badder Bomb Blast | Gallywix starts moving and can now follow Tanks. This mechanic is identical to Big Bad Buncha Bombs one. However, Tank Combo now deals AoE damage in 30 yards. Overloaded Rockets are similar to Sapper’s Satchel but now fire three rockets from marked players. Heroic: 1500-Pound “Dud” bomb mechanic remains during this phase. | Move away from the Tank marked with Bigger Badder Bomb Blast. Make sure to dodge projectiles from Overloaded Rockets. Heroic: Keep dealing with the 1500-Pound “Dud” bomb. |
| Tick-Tock Canisters | Boss throws Canisters to the arena. Canisters explode, dealing damage and applying absorb health to the soaking players or the whole raid if not soaked. | At least one player must soak each Canister to avoid damage and heal absorb being applied to the raid. Heal through the absorb. |
| Suppression | This skill is now followed with Gallybux Finale Blast that creates a big area that explodes and deals heavy damage that lessens with range. | Dodge swirlies and run away from Gallybux Finale Blast zone. You might need to use mobility skills to do it in time. |
On Heroic difficulty, there are a few changes to Normal raid mechanics and an extra Tank combo mechanic.
| Ability | Description | Tip |
|---|---|---|
| Bigger Badder Bomb Blast | Heroic: 1500-Pound “Dud” bomb mechanic remains during this phase. | Heroic: Keep dealing with the 1500-Pound “Dud” bomb. |
| Tick-Tock Canisters | No change. | No change. |
| Suppression | No change. | No change. |
| Heroic: Ego Check | Boss performs a Tank combo, dealing four damaging hits. All unmitigated damage transfers into DoT debuff. | Swap Tanks to increase your chances of surviving after each cast. Use defensives during hits to reduce further DoT damage. |
