Diablo 2 was originally planned to release a second expansion after "King of Destruction", called "Reden".Recently, David Brevik, one of the main creators of the game, revealed this detail in an interview.

David Brevik mentioned that Diablo 2: Redemption plans to add a new profession "priest" and include some of the content that was not designed in detail.These contents were put on hold because Blizzard decided not to continue the project.

In the end, Diablo 2: Redemption was cancelled and the development resources were transferred to Diablo 3.During the development of "Dark 3", Blizzard had to disperse the team to different tasks due to the emergence of multiple new projects, resulting in a significant extension of development time.Finally, in 2012, "Dark 3" was officially released.
