Blizzard Entertainment has released the Reign of the Warlock expansion for Diablo II: Resurrected, introducing the first new character class to the game in over 25 years. The Warlock, a summon-based class blending melee and ranged combat, arrives as a $24.99 paid add-on. This update marks the start of ongoing development for the remastered classic, with the class also planned for Diablo IV and Diablo Immortal.
The Reign of the Warlock expansion launched on February 11, 2026, bringing the Warlock class to Diablo II: Resurrected, the 2021 remaster of the 2000 action RPG. According to Blizzard developers in interviews, the team considered three or four potential classes before selecting the Warlock due to internal enthusiasm. "We started with maybe, I don’t know, three or four [classes] that were top of mind," said game producer Matthew Cederquist. Game designer Tim Vasconcellos explained efforts to integrate the class seamlessly: "We looked at the warlock and said, ‘Okay, so what would make this feel as if we were coming out of Diablo I and this is a class that would have launched with Diablo 2?’" Subtle nods, such as Diablo I icons in the skill tree, aim to make it feel like a natural addition.
The Warlock features a demon-taming skill tree allowing players to dominate and use or consume demons for power, adding micro-management elements tailored to Diablo II's gameplay. The expansion also includes enhanced Terror Zones, over 30 new items like Uniques and Runewords, quality-of-life improvements such as loot filters, advanced stash tabs, and a Chronicle database to track loot finds. An Infernal Edition bundle costs $39.99 on platforms including Steam.
Announced during the Diablo 30th Anniversary Spotlight event, the update creates two versions of the game: the time-locked classic Diablo II: Resurrected and the evolving Reign of the Warlock mode. Blizzard emphasized preserving the original experience, with developers noting, "We don't want to mess up the Mona Lisa." The Warlock's reception will influence future additions, as the team consists of longtime players hoping to extend support beyond the anniversary.
The class extends to other titles: in Diablo IV's Lord of Hatred expansion on April 28, 2026, as a dark counterpart to the Paladin; and in Diablo Immortal in June 2026, alongside the Lut Gholein location. Each version adapts the Warlock to its game's style.
