Open Beta and Early Access Weekends Duration
Early Access to the Open Beta begins March 17 at 9 a.m. PDT and concludes March 20 at 12 p.m. PDT.
The Open Beta begins March 24 at 9 a.m. PDT and concludes March 27 at 12 p.m. PDT.
During the Early Access weekend, players will have access to three classes. Assume the role of the battle-bred Barbarian, nimble Rogue, or elementally tuned Sorcerer. Once the Open Beta weekend comes around, the earthen Druid and undead-wielding Necromancer classes can also be played in addition to the original three.
A maximum of 10 characters can be made per Battle.net account. After reaching Level 25 with one character, we recommend you try repelling demonic hordes with additional classes to find your favorite. While progress will transfer from Early Access to Open Beta weekends, all characters made during these weekends will be deleted once the Beta ends.
