Blizzard Entertainment announced a second expansion for Diablo 2, titled Reign of the Warlock, during the Diablo 30th anniversary Spotlight video. The last expansion, Lord of Destruction, was released 25 years ago. The new expansion introduces a warlock class that allows players to summon three different demons and bind one enemy demon for powerful buffs. Quality-of-life improvements include stash tabs that allow item stacking, unique tabs for specific categories, loot filters for item visibility, and a comprehensive item collection list. Diablo 2: Reign of the Warlock is now available on Battle.net.
