Greetings!

Dragonflight Mythic+ testing will once again be available on Beta this weekend. The test period will begin Thursday November 10th at 10:00 PDT (13:00 EDT, 20:00 CEST), and end Monday November 14th at 10:00 PDT (13:00 EDT, 20:00 CEST). Please note that the test period may be adjusted in the event of technical difficulties.

This weekend mainly features a lot of tuning, bug fixes, and quality of life improvements. We’d particularly appreciate testing with affixes to help us identify any issues with affix interactions in specific dungeons.

During the test period you’ll be able to acquire and customize Mythic Keystones by talking to the Keystone Vendor in Stormwind or Orgrimmar, and the nearby Dungeon Teleports NPC will assist you with transportation.

We look forward to hearing your feedback!
