First, head to the room next door to the Grim Guzzler, which is the same room as the Brewfest boss or just down from the entrance. This room will be empty. Look for three brew barrels and destroy them by clicking on them. This will summon Hurley Blackbreath and his crew running in to investigate the commotion.
Picking a Fight with Hurley Blackbreath
With Hurley and his crew now in the Grim Guzzler, it’s time to pick a fight. Hurley is an elite Dark Iron dwarf who inflicts fire damage to all players in a cone in front of him. To take him down, you’ll need to coordinate with your group and focus your attacks.
Defeating Plugger Spazzring
Next, head over to the tables near Plugger Spazzring and steal items off them. This will anger Plugger and he’ll attack you. Plugger is another elite Dark Iron dwarf who must be defeated to progress.
Provoking Ribbly Screwspigot
The final patron to pick a fight with is Ribbly Screwspigot. Simply talk to the little hothead and he’ll attack you. Ribbly is a level 60 elite Dark Iron dwarf who must be slain to complete this challenge.
Once you’ve defeated all three patrons, report back to Thunderheart to complete the quest and move on to the next area of Blackrock Depths.
