Blizzard has taken to the Diablo 3 website
to outline just what players can expect from Reaper of Souls' upcoming 2.1.0 patch, including a new "Seasons" mode that brings a number of unique quests and challenges to the game.
The new Seasons mode will work similarly to Diablo 2's Ladders, whereby players will roll back to level 1 at the start of each season as they work toward earning mode-specific achievements called Conquests. They will also gain exclusive rewards and unique Legendaries depending on their progress, and will also get to compete across a new leaderboard system that will track progress across each specific Season.
Reaper of Souls version 2.1.0 will also introduce Greater Rifts, which are more challenging versions of Nephalem Rifts that can be unlocked via random Rift Guardian drops. The previously mentioned leaderboards for Seasons will also be available for these new Greater Rifts. A new area is also planned for the patch, titled The Cesspool, which was originally planned for launch with Reaper of Souls but had been pushed back for further development time.
