Blizzard's first expansion pack for Diablo III will be coming to digital download and retail on March 25. Gamers will be able to choose the Standard Edition priced at $39.99, the Digital Deluxe Edition which carries an MSRP of $59.99 or the retail-exclusive Collector's Edition at $79.99.

Reaper of Souls will deliver a number of new features including a new act that will take place in Westmarch, a new playable hero known as The Crusader, updated loot rewards, all-new class skills and abilities, replayable content in the form of Bounties and Nephalem Rifts, a new Adventure Mode and the new Mystic NPC who provides heroes with loot-customization options.

If that weren't enough, the Digital Deluxe Edition adds a wealth of in-game bonuses such as exclusive helm- and weapon-transmogrification recipes, a Spectral Hound minion that players can summon to keep their adventurers company, three additional character slots to accommodate new heroes, a World of Warcraft in-game companion pet known as the Treasure Goblin and a set of StarCraft II Crusader-themed Battle.net portraits and Malthael-themed decals.

Finally, the Collector's Edition will include all of the bonus items from the Digital Deluxe Edition in addition to a full-color hardcover art book, a behind-the-scenes Blu-ray/DVD two-disc set and a mouse pad bearing the image of Malthael, the Angel of Death. It'll only be available through select retailers so you'll need to keep an eye out for it as the launch date approaches early next year.

Diablo III: Reaper of Souls is available for pre-order as of writing.
