Welcome to the Undermine and welcome back to the Isle of Kezan! The glowing, neon underworld of the goblins which looks suspiciously…a lot like many of their outposts above ground. Still as tacky, shiny and colourful as ever - as explorers and adventurers we look to get rid of Galliwix for the the last time by tracking him down and ending his reign once and for all.

The Undermine is the subterranean capital city of the Goblins, nestled in the middle of an active volcano - Mount Kajaro. Consisting of many towns such as Pyrix, the whole city has a slick, oily feel about it. It’s the kind of city that even the air makes you feel dirty. When Deathwing attacked the Isle of Kezan, he activated Mount Kajaro and it was assumed that The Undermine was destroyed by lava. This has now been shown to be incorrect…

As the capital of the Goblin culture, both alchemists and tinkers practice their craft whilst setting off explosions. Undermine is also to the headquarters of the Trade Coalition, the Venture Company and a strange mix of other enterprises within the city.

(Fun fact: THE MOTHERLODE! was called The Undermine in an alpha version of Battle for Azeroth)

There’s eight boss encounters within Undermine that include machines, explosives and even an ogre! (It’s been a while since we had an Ogre boss…) The raid is set into four wings and three of the wings must be completed before we get to the House of Chrome which is where Chrome King Galliwix has positioned himself. We’ve seen what he’s capable of and at this point…it could actually be anything.

The raid is associated with a Renown track entitled the Gallagio Loyalty Rewards Club. This adds quality of life features to the Intercontinental Hotel, including a mount, a teleport to the raid and a +18 to damage and healing as players rank up through the renown. We’re also seeing the return of tier tokens for those of you that like that mechanic.

Raid Route

BOSS GUIDES

Vexie Fullthrottle & The Geargrinders

🏆 Heroic Changes

  • Boss now has 6 Protective Platings.

  • Big purple circles should now move away from the boss as well as players, as it leaves oil that slows and deals damage over time.

  • The tankbuster (fittingly named Tank Buster) now also leaves behind oil on the ground. Move the boss away from it after swapping.

  • Any oil left on the ground will stop the bikes that are thrown by players, so you want it out of the way in order to provide a clear shot at the boss.

  • In order to manage the oil, you can tank the boss on the edges of the room and have her rotate around the arena, with the oil placed towards the previous boss position.

Vexie Simplified

  • Kill bikers and throw bikes at boss.

  • Do big damage and stop enemy casts during the intermission.

Cauldron of Carnage

🏆 Heroic Changes

  • On Gorilla, lightning-clones will fixate at players and explode when coming into contact with any player, leaving behind a permanent puddle of lightning. After 12 seconds, they disappear on their own, so CC and kite them around.

  • On T-Rex, players will occasionally have to spread lightly in order to avoid overlapping Molten Phlegm circles which target players. Typical spread-circles.

  • Also on T-Rex, the big bomb now leaves behind a fire puddle. Try to bait the bomb by the wall whenever possible in order to avoid ground clutter.

Cauldron of Carnage Simplified

  • Split raid.

  • If on T-Rex, soak bombs and aim beam away

  • If on gorilla, stutter step and dodge puddles.

  • Swap on intermission.

Rik Reverb

🏆 Heroic Changes

  • Damage from soaking Amplifiers gets more intensive the longer you soak. Rotate soakers.

  • Pyrotechnics (exploding barrels ) will be thrown out that must be killed before they explode and wipe you. You have 15 seconds to kill 4 of them, so they take absolute priority.

  • Pyrotechnics give stacks of haste and movement buffs to players attacking them.

Rik Simplified

  • Try to bait amplifiers close to raid.

  • Drain amplifiers (click on them).

  • In intermission, stand in each of the glowing amplifiers to avoid wave damage.

Stix Bunkjunker

🏆 Heroic Changes

  • Hyenas bite you, doing damage and putting a heal reduction on you.

  • It is now much more important to interrupt Scrapmasters.

  • Bombshells will be guarding certain trash piles. Reduce their health to 80% in order to detach them from the trash piles. They will explode for huge damage if they are not killed.

  • If ball of garbage rolls over a Bombshell add, the ball is destroyed and the raid takes huge damage.

Stix Simplified

  • Kill any adds that you see.

  • Balls roll over small trash until medium sized, then run over big trash.

  • Balls roll into big bomb or boss.

Sprocketmonger Lockenstock

🏆 Heroic Changes

  • Each Phase 1 has a set of 4 mines which must be run over by players to prevent them from exploding on the raid. They must be activated 2 seconds apart or they will cause a wipe.

  • Players who trigger a mine will get a 2 minute debuff, so they must be rotated.

Sprocketmonger Simplified

  • Dodge, dodge, dodge. In phase 2, don't get knocked off the platform. Don't stand in lightning.

One-Armed Bandit

🏆 Heroic Changes

  • All Bomb Rewards deal damage-over-time on addition to the hit.

Bandit Simplified

  • Kill big adds as they spawn, deposit symbols as called by raid leader, CC and destroy any fixating bombs, stand near coins for a buff.

  • After 30%, boss starts an enrage timer. During this, don't stand in coil tethers, point fire lines away from the raid, and survive big raidwide damage.

Mug'Zee

🏆 Heroic Changes

  • Players afflicted by Frostshatter Boots will get targetted by a fatal ice spear. Nobody stand in the path. Bait it into a Gaol wall or Crawler Mine.

  • If you get hit by a Crawler Mine, future Crawler mines hurt more.

  • When a Crawler Mine explodes, it throws out soaks. These hurt a bit, but soaking prevents higher raidwide damage, so have one player in each.

  • If you soak a rocket, future rockets hurt more for a period, so rotate soakers.

Mug’Zee Simplified

  • Everyone start on the same side. On earth side, soak big circles near a wall and kill the add. On metal side, soak big fire circle and kill adds. Step into mines on Metal side but not at the same time.

  • Follow the boss in the intermission and rotate with him to avoid big cones.

Chrome King Gallywix

🏆 Heroic Changes

  • If anyone is hit by the brown circle's explosion in Phase 1, it will spread to them as well.

  • Bombs take less time to explode, so deal with them even faster.

  • Destroying the coils with bombs now has tighter timing and has to be done at most 20 seconds before reaching 100 energy.

  • All healing absorbs in the fight now explode if they're not dealt with quickly enough.

  • Tanks now have to deal with a special type of bomb, 1500-Pound "Dud", in every phase. The tank needs to interact with the bomb to disarm it, which deals a lot of damage and applies a stacking DoT.

Gallywix Simplified

Phase 1:

  • Split the raid in Two.

  • Take turns soaking the frontal.

  • Avoid the massive bomb looking circle thing.

  • Dodge everything else.

Phase 2:

  • Kill Adds ASAP

  • Pick up Bombs. Drop one on the activated pylon. Drop the others in the hole in the middle or off the edge.

  • Assign someone fast to deactivate the pylons when they all become active.

  • Make sure the bombs don’t get hit by the frontal beam from the boss.

Intermission:

  • Don’t stand in the brown circle.

  • Nuke the absorb shield and interrupt Gallywix.

Phase 3:

  • Stack where possible. There will be a lot to dodge on the floor.

  • Tanks run bombs away (red circles)

  • Everyone soak the canisters.

  • Run away from Gallywix for final blast.

  • Tanks disarm the ‘dud’ bomb.
