Reaper of Souls is described as a "dark and terrifying new chapter" in Diablo's story and takes place "from the sprawling streets of Westmarch to the ancient walls of the Pandemonium Fortress." It follows Malthael, the "fallen Archangel of Wisdom" who "returns as the Angel of Death and seizes the Black Soulstone, which contains the essence of the Prime Evil. It now falls to the players to track down Malthael and stop him before he unleashes irreversible havoc on the world."
Reaper of Souls will add Act V and increases Diablo III's level cap to 70, plus new spells and abilities for existing Barbarian, Witch Doctor, Demon Hunter, Wizard, and Monk characters will be added. According to Blizzard, Reaper of Souls "also accentuates the key features of the Diablo franchise, with a greater emphasis on randomized environments to explore; epic new quests; horrific new monsters to defeat; and substantial updates to the loot experience, enabling players to further customize their characters with new and improved multilevel Legendary items, new Blacksmith and Jeweler item-crafting options, and more."
The expansion will also offer new quests, new monsters and two new game modes: Loot Runs and Nephalem Trials, which are "designed to provide players with a highly replayable (and highly rewarding) end-game experience." The Paragon progression system will be "majorly upgraded" for Reaper of Souls, and "more end-game character advancement and replayability" will be added as well.
“From the beginning, Diablo has always been about the struggle between good and evil, and Reaper of Souls explores the darker notes of that conflict,” said Blizzard CEO Mike Morhaime. “This expansion also represents a big milestone in the ongoing evolution of Diablo III, with key enhancements to the core gameplay, along with a new act to experience, a powerful new character class, tons of new loot, and even more end-game options. We think players will love playing Reaper of Souls, and we can’t wait to get it into their hands.”
No release date has been announced for Reaper of Souls yet, but look out for more info coming from Gamescom this week, including an interview with Blizzard.
