Blizzard has updated the official Patch 11.1 notes to clarify a key change for the new Undermine world boss, the Gobfather. Instead of dropping random loot tailored to a player’s specialization, the Gobfather will now guarantee a warbound-until-equipped item on your first kill each week per account.
Added the following change to the update notes:
THE GOBFATHER WORLD BOSS
- The Gobfather drops a warbound-until-equipped item on the first kill each week per account rather than a random chance at equipment matched to a player’s specialization.
