Entitled Revenge of the Plague Lord, the expansion includes four new Hero professions—Bard, Rogue, Ranger, and Warlock—alongside 25 new quests. New monsters and bosses, 50 new spells and 40 new items are also arriving as part of the expansion.

The expansion will be available for 700 Microsoft Points ($8.75) when it debuts on the Xbox Live Marketplace this Wednesday.
