The Dark Iron Guzzlers raid the Brewfest every half-hour during the event under Coren Direbrew's orders. They attack both Dun Morogh and Durotar indiscriminately, seeking only to end the festivities. They are not fought directly like the Shade of the Horseman during Hallow's End but instead must be incapacitated by players who must drink and then throw Complimentary Brewfest Samplers at them. If players fail to defeat all of the Guzzlers, the dwarves will destroy the free beer kegs and players must wait for them to be rebuilt and restocked.
