Blizzard is launching a new Warlock class across the Diablo universe to celebrate 30 years, debuting today in Diablo 2: Resurrected, arriving in Diablo 4 in April, and hitting Diablo Immortal in June.

In Diablo 2: Resurrection, the Warlock is available now as part of the Reign of the Warlock expansion for $25, adding new zones, items, and other content.

Diablo Immortal will welcome the Warlock in the summer of 2026 alongside the Andariel Rises campaign update planned for the year.

The Warlock is framed as a master of forbidden knowledge who binds demons to defend Sanctuary rather than serve Hell.

Developers emphasize expanding build variety, tracing the Warlock’s origins from Diablo 2 to its evolved forms, and ensuring multiple endgame paths instead of a single endpoint.

The broader release also introduces two new classes across the game line, a refreshed endgame loop with Warplans and Echoes of Hatred events, and system updates to support diverse builds and progression.

The Warlock is described as a dark scholar who can bind demons and unleash powerful magic, with updates including Terror Zones, Colossal Ancients, and QoL improvements.

The Warlock is a demon-summoning, damage-dealing class who powers up by consuming demons, with a distinct personality for each game version.

The overall celebration centers on strengthening Diablo’s longevity through cross-title content and new gameplay mechanics, appealing to both veterans and new players.

Diablo 2: Resurrection is on Game Pass Ultimate & Premium but does not include the Reign of the Warlock expansion.

Diablo Immortal’s Warlock arrives in June, extending the Warlock storyline across the franchise and expanding the mobile experience.

Diablo 4’s Lord of Hatred expansion launches April 28, 2026, bringing the Warlock, Paladin, new endgame systems, and the Skovos region.
