How The Big G drops
Keys to the Big G is the collection item. It drops from Mythic 
Chrome King Gallywix, last boss of 
Liberation of Undermine from The War Within. The printed farm rate is about 1% per kill. That rate is the legacy farm. While the 
raid was the current tier the 
mount sat on a guaranteed system; that guarantee is gone. Heroic, Normal, and Raid Finder reprints we opened do not list the mount. A shop page that promises any difficulty is selling a different product than this drop.

Lockouts and the current season
Mythic Gallywix is a weekly lockout. 1 kill per character per reset can roll the mount. Group size is a 20-player Mythic raid. Our weekly reset page is the Tuesday and Wednesday clock. There is no special Undermine timer. Midnight Season 2 opened on 18 August 2026 on the Venomous Abyss. Undermine is the previous raid. It is still listed in the Adventure Guide, so a character that can enter Mythic still walks in and takes 1 shot a week. Pug or guild is your roster choice.
What to do this week
Open the journal. If Liberation of Undermine is listed, book or pug a Mythic Gallywix kill before reset. If the character is short of Mythic item level, finish the current Venomous Abyss lockout or a Season 2 key, then come back. LFCarry can take a named Mythic lockout through a custom order. There is no printed Big G dollar on this page. Sibling pages: Midnight raid, weekly reset, Obsidian Worldbreaker.
Why the 1% farm is the real clock
A weekly 1% roll is a long farm. 1 character is 1 die per reset. Alts multiply the dice; they also multiply the lockout work. The current-tier race for this raid is over. The mount is a leftover chase from The War Within. Plan the week around the Tuesday flip, then spend the rest of the reset on Season 2 gear so the next shot is easier.
