The Big G is one of the most absurd and memorable mounts introduced in The War Within. This enormous mechanical ride looks like a goblin’s face transformed into a mobile war machine — glowing eyes, reinforced metal plating, side-mounted cannons, and a design that perfectly captures chaotic goblin engineering. For collectors who appreciate mounts with strong personality and unmistakable presence, The Big G remains a standout addition to any collection.
What truly defines The Big G today is its rarity. The mount item, Keys to The Big G, drops exclusively from the final boss of a Mythic raid — and since the release of Midnight, the drop chance has transitioned into legacy mode. Instead of being protected under a guaranteed system, the mount now has an estimated ~1% drop rate, turning it into a true long-term weekly farming challenge.
The Big G mount is exclusively obtained from the final boss of the Liberation of Undermine raid on Mythic difficulty. You must defeat Chrome King Gallywix on Mythic — Normal and Heroic difficulties will not award the mount.
Since the Midnight expansion launched, Liberation of Undermine is no longer current-tier content. As a result, The Big G now follows the traditional legacy mount model with an approximate 1% drop chance per weekly kill. This dramatically increases the time investment required, as players must rely purely on weekly resets and persistence rather than guaranteed systems.
Before organizing a Mythic run, make sure your character meets the baseline requirements:
If you cannot enter the raid, you may need to complete associated unlock quests or progress through the K’aresh campaign. Certain prerequisites, including zone phasing and introductory quest steps, must be completed before you can zone into the instance.
The raid entrance is located near the central complex. Use the coordinates below to locate it quickly:
Raid Entrance: - 41.8, 49.0
Once inside the instance, progress through the raid until you reach the final encounter with Chrome King Gallywix. This boss is the only source of The Big G.
Unlike during its active season, the mount is no longer guaranteed for the group. Each weekly Mythic kill now provides an independent low-probability chance for Keys to the Big G to appear in the loot table. With an estimated ~1% drop rate, patience and consistency are now the primary factors in securing this mount.
After defeating Chrome King Gallywix, check the loot carefully. If Keys to the Big G appears, ensure it is correctly assigned according to your group’s loot rules.
Once looted, simply learn the item and the mount will be permanently added to your collection. The Big G remains a visually striking mechanical mount with unique flair — and now represents true legacy raid dedication.
Even though Liberation of Undermine is no longer current progression content, Mythic mechanics still require coordination — especially if you are running with smaller or undergeared groups. These addons help streamline execution and track weekly attempts.
Tracking resets across multiple alts is especially important when farming a low-percentage mount like this one.
