Around March 2015, a sequel, Duel of Champions 2, was planned. The game would focus more on might and magic skills (fortune, building and event cards were disbanded), and a new faction, Sylvan, was to appear. However, the project was soon canceled, due to lack of developers and an increase of trading card games.
The original Duel of Champions missions had two campaigns, which showed a map to show where the group was headed to. However, it was scrapped in the favor of the new campaigns. Thus, some of the characters were scrapped, e.g. Sayuri.
There was supposed to be an additional expansion pack, which would feature siege weapons and dragons (the latter being one per elemental school), and even an epic event card. However, the idea was later scrapped, although certain resources, like alternative artworks of Sveltana, Hierophant of the Spider Queen, Shrine of Elrath or Fortune telling remained in-game files.
The game was shut down on October 31, 2016.
