While Diablo 3 of course is required to play Reaper of Souls, Blizzard will be offering both a Standard Edition as well as a Digital Deluxe Edition. Players are able to pre-purchase the Reaper of Souls Expansion starting today from Battle.net.
Blizzard has commented that the release of Reaper of Souls will take Diablo 3 back to its darker roots which will in turn give player a new experience playing Diablo 3. A new character class called “The Crusader” will be at the center of the new offerings of the expansion pack in addition to a new “Adventure Mode” that allows for travel between away points set in the game. The loot system has also been redesigned and adds “smart drops” to give players better loot at an enhanced pace.
