Overview

Gnomeregan was the gnomes' capital until the troggs broke in from below and the city was flooded with radiation to stop them. What's left belongs to Mekgineer Thermaplugg, the gnome who betrayed his people, along with his robots, the irradiated leper gnomes and the troggs that never left.

It's a long dungeon with a lot to show for it: 27 quests between the two factions, blue drops for every role, and a stack of Engineering schematics from the final boss. Block out a long session and bring a full group.

Getting there

Gnomeregan's entrance is in the mountains of western Dun Morogh, west of Kharanos. The instance portal sits at the bottom of the ruined city's outer halls, so expect a few fights on the way down.

Dun Morogh is Alliance territory. Horde groups have their own quests here, but the trip in is long. After your first clear, the Workshop Key gives you a back way in: see Electrocutioner 6000 below.

Quests

Gnomeregan has 27 quests on its list, and they sort cleanly. Most are Alliance quests that hand in at Ironforge, Kharanos and Stormwind, the Horde chain runs through Booty Bay and Orgrimmar, and a handful work for both factions. Pick up everything for your side before you go: the quests both factions share start inside the dungeon.

Alliance

Four "speak with" quests introduce you to the gnomes who want things from Gnomeregan: Tinkmaster Overspark and Castpipe's Task (Tinkmaster Overspark and Master Mechanic Castpipe in Ironforge), Klockmort's Essentials (Klockmort Spannerspan in Ironforge) and The Day After (Ozzie Togglevolt in Kharanos). Then:

  • Save Techbot's Brain!

    Level 26Requires 20Alliance

    Techbot's Memory Core for Tinkmaster Overspark.

  • Data Rescue

    Level 30Requires 25Alliance

    A Prismatic Punch Card for Master Mechanic Castpipe.

  • Essential Artificials

    Level 30Requires 24Alliance

    12 Essential Artificials for Klockmort Spannerspan.

  • Gnogaine

    Level 27Requires 20Alliance

    Use the Empty Leaden Collection Phial on Irradiated Invaders or Irradiated Pillagers until it's full, then take it to Ozzie Togglevolt.

  • The Only Cure is More Green Glow

    Level 30Requires 20Alliance

    High Potency Radioactive Fallout for Ozzie, who also wants the Heavy Leaden Collection Phial when you're done. The fallout is unstable and collapses quickly, so collect it last and head straight back.

  • Gyrodrillmatic Excavationators

    Level 30Requires 20Alliance

    24 Robo-mechanical Guts for Shoni in Stormwind.

  • The Grand Betrayal

    Level 35Requires 25Alliance

    Kill Mekgineer Thermaplugg and return to High Tinker Mekkatorque.

Horde

  • Chief Engineer Scooty

    Level 35Requires 20Horde

    Sends you to Scooty in Booty Bay, and Gnomer-gooooone! has you wait while Scooty calibrates the Goblin Transponder.

  • Rig Wars

    Level 35Requires 25Horde

    Retrieve the Rig Blueprints and Thermaplugg's Safe Combination from Gnomeregan for Nogg in Orgrimmar.

Both factions

  • A Fine Mess

    Level 30Requires 20

    Escort Kernobee to the Clockwerk Run exit, then report to Scooty in Booty Bay.

  • The Sparklematic 5200!

    Level 30Requires 25

    Put a Grime-Encrusted Object and three silver coins into the Sparklematic 5200. More Sparklematic Action runs another one through. The list shows several copies of both: they're the same job.

  • Grime-Encrusted Ring

    Level 34Requires 28

    Get the grime off the Grime-Encrusted Ring, which also costs three silver. Then Return of the Ring (Alliance) or Return of the Ring (Horde) lets you keep the ring or track down whoever left the imprint and engravings inside the band.

1. Techbot

Level 26

Loot (1)

Abilities

  • Battle NetImportant

    Immobilizes nearby enemies for 10 sec.

  • LagMagic effect

    Increases the time between an enemy's attacks by 54% and its movement by 60% for 10 sec. Lag also results in link death, stunning the enemy for 8 sec.

  • Summon Dupe BugDamage dealers

    Summons 1 Dupe Bug to aid the caster in battle for 1 min.

2. Grubbis

Level 32EliteShow on map: Grubbis

Loot (1)

Grubbis only appears if you run Blastmaster Emi Shortfuse's event. Talk to her and she starts setting charges to seal the trogg tunnels, while troggs pour out at her in waves. Hold them off until both tunnels collapse, and Grubbis arrives with his pet Chomper.

Kill Chomper first, then Grubbis, and keep Emi alive the whole way: the event depends on her. Grubbis drops Grubbis Paws, mail gloves with Strength, Agility and Spirit.

  • Tank

    Stand next to Emi so the troggs run into you, and grab anything that reaches her.

  • Healer

    Heal Emi as well as the group. She's the objective.

  • Damage

    Kill whatever is hitting Emi first. When Grubbis arrives, burn Chomper, then Grubbis.

4. Electrocutioner 6000

Level 32EliteShow on map: Electrocutioner 6000

Loot (4)

The security robot carries the Workshop Key, so make sure someone loots it. The key opens the Workshop Door at Gnomeregan's back entrance, a shortcut for your later runs. Its Megavolt hits a cone in front of it, so only the tank should stand there, and Chain Bolt jumps between players, so interrupt it.

Abilities

  • MegavoltCan be interrupted

    A 2-sec cast blasting the area ahead of it with Nature. Keep everyone but the tank out of the front.

  • Chain BoltCan be interrupted

    Lightning that leaps from one player to the next, after a 2.5-sec cast. Interrupt it.

5. Crowd Pummeler 9-60

Level 32EliteShow on map: Crowd Pummeler 9-60

Loot (3)

The Pummeler's Crowd Pummel hits everyone standing next to it and interrupts their spellcasting. Keep your healer and casters at range, and let only the tank and melee stand in reach. Its drop Manual Crowd Pummeler is a two-handed mace you can use to raise your attack speed by 50% for 30 sec, once every 3 minutes.

  • Tank

    Hold the Pummeler where you pick it up. Every step toward the group brings your healer into Crowd Pummel's reach.

  • Healer

    Stay out of melee range. Crowd Pummel interrupts spells cast next to it, so you can't heal from its feet.

  • Damage

    Ranged, keep your distance. Melee, you take Crowd Pummel hits along with the tank, so watch your health.

Abilities

  • Crowd PummelImportant

    Pummels nearby enemies for normal damage plus 10 and interrupts any spell being cast 75% of the time for 5 sec.

  • Arcing SmashTank

    A swing that hits every player in front of it.

  • Trample

    Damages everyone in melee range of it.

6. Mekgineer Thermaplugg

Level 34EliteFinal bossShow on map: Mekgineer Thermaplugg

Loot (9)

The traitor fights from inside his mech in a chamber at the end of the dungeon, and six bomb bays, each a gnome face on the wall, ring the room. During the fight he activates them, and Walking Bombs march out and explode when they reach you, hitting everyone nearby.

Every bay has a button beneath it: press the button under an active bay to shut it down. Once he drops under half health the bays light up more often, and his Knock Away, which knocks the tank back, then hits everyone around him. Give one player the buttons and have everyone else kill any bomb that gets loose. Killing Thermaplugg completes The Grand Betrayal.

  • Tank

    Hold Thermaplugg where he stands and let the rest of the group handle the bombs.

  • Healer

    A bomb that gets through hits everyone near it. Keep the whole group topped up, not just the tank.

  • Damage

    One of you runs the buttons. Everyone else kills loose bombs first, then goes back to Thermaplugg.

Abilities

  • Walking BombsImportantDeadly

    One by one he wakes the gnome faces on the walls, and each spits out bombs that walk to a player and blow up. Press the button beside a face to shut it; below half health he wakes them faster. Assign people to the buttons.

  • Knock AwayTank

    Sends the tank flying; once he is under half health, the whole melee group gets it too.

Trash and pulls

  • Gnomeregan mixes humanoids (troggs, leper gnomes and Dark Iron dwarves) with robots and radioactive oozes. Sap and Polymorph only work on the humanoids. For robots, use Freezing Trap, which works on anything, or burn them down.
  • Leper gnome packs mix elites with non-elites. AoE the small ones down while the tank holds the elites.
  • It's a long dungeon, so pull at a steady pace and don't chain packs to save time. A wipe deep inside costs far more than a careful pull.

Tips

  • Tip

    Stack your faction's quests before you go: Ironforge, Kharanos and Stormwind for Alliance, Booty Bay and Orgrimmar for Horde.

  • Tip

    Loot the Workshop Key from Electrocutioner 6000. It's your back door for the next run.

  • Tip

    Put your most alert player on Thermaplugg's buttons, not the tank or the healer.

  • Tip

    Clean your Grime-Encrusted Objects at the Sparklematic 5200 before you leave, and bring silver: every run through the machine costs three.

  • Tip

    Alliance: collect the High Potency Radioactive Fallout last and go straight to Ozzie, before it collapses.
