Reaper of Souls Expansion details:

- In addition to expanding the story of Diablo III with an all-new, action-packed Act V and introducing the incorruptible Crusader class, Reaper of Souls increases the game's level cap to 70. Players forging ahead with their existing Barbarian, Demon Hunter, Monk, Witch Doctor, and Wizard characters will benefit from an array of fearsome new spells and abilities as they advance in level. - The expansion also builds upon several key features of the Diablo franchise, with a greater emphasis on randomized environments, horrific new monsters, epic new quests, and substantial updates to the loot experience. The redesigned loot system in Reaper of Souls focuses on rewarding players with even better treasure through targeted "smart drops," new and improved multi-level Legendary items, and a third artisan, the Mystic, who can augment an item's power and appearance.

- A new Adventure Mode has been added as well; with all Waypoints unlocked in this mode, the entire world becomes the player's battlefield! Included in Adventure Mode are two new game features, Bounties, a randomized objective system, and Nephalem Rifts aka Loot Runs, a randomized dungeon system, provide fun and rewarding challenges for players to tackle when they're looking for new ways to test their might. Diablo III's Paragon progression system will also be receiving several updates for the expansion, adding even more endgame character advancement and replayability.
