How to get it

Drops from Chrome King Gallywix, last boss of Liberation of Undermine, on Mythic only.

Chance 1% once a week, so about 100 tries on average — unofficial; reported as about 1% since Midnight launched, was guaranteed before. Wowhead (read 2026-10-10) records 20 mounts in 152 Mythic loots of Chrome King Gallywix (13%), but that is a small sample and looks like the earlier time, when the guaranteed copies were shared out among a raid of 20, so it is not taken as today's chance
