Cataclysm beta: Raids begin testing on October 17
Endgame raiders, start paying attention -- Daelo, Blizzard's lead encounter designer, has announced that beta raid testing will begin on Oct. 17. It looks like Blizzard wants to test the first raid encounters, Halfus Wyrmbreaker and the Omnitron Defense System, in the Bastion of Twilight and Blackwing Descent respectively. I eagerly anticipate the fight mechanics and abilities of these bosses more than you probably know.
Omnitron Defense System in Blackwing Descent
Halfus Wyrmbreaker in The Bastion of Twilight
Blackwing Descent is a raid zone with an entrance located along the side of Blackrock Mountain.
The Bastion of Twilight's entrance is located within Twilight Highlands.
Since these are the beta realms, this schedule is subject to change at a moment's notice due to bugs and server issues. More raid tests will be occurring over the next few weeks.
