The Primal Hunt. “The crater’s jungle wakes hungry. Ravasaur packs run the ferns, the pterrordax circle overhead, and King Mosh shakes the ground on his way to the kill.” Un'Goro Crater is zone 4 of 12, and its final boss is King Mosh.
How to unlock Un'Goro Crater
Un'Goro Crater comes after Warsong Gulch in the game’s zone order. The zone menu keeps a zone locked until you defeat a named final boss; in this order that is Lord Kazzak. Surviving until that boss arrives is not enough; the menu asks for the kill. After King Mosh comes Arathi Basin. Opened zones are saved per class.

Sources & scope
Zone and boss records read from the original game’s v0.103.1 (671c6f5e) WebAssembly build on 2026-10-20. The zone record holds no unlock requirement: the order is the order the game stores its 12 zones in, and the zone menu’s lock text names a final boss. In v0.91.2 each zone opened after the final boss of the zone before it; we have not checked in play that this still holds with Un’Goro Crater, Scarlet Monastery and Naxxramas added. Boss health is the base value stored in the game data. The zone, run options and level change what you meet in a run, and we have not measured them.
