What did Blizzard announce about the Warlock class?

A new class is being rolled into multiple Diablo titles for the 30th anniversary

Blizzard used its Diablo 30th Anniversary Spotlight to introduce the Warlock as a cross‑game addition. The announcement covers multiple entries in the franchise rather than a single release, marking the Warlock as a franchise‑level update tied to anniversary plans.

Concrete details revealed

• Diablo II: Resurrected received a Warlock expansion or DLC that is available now; this is notable because it’s the first entirely new playable class for that game in decades.
• The Warlock will also be added to Diablo IV as part of the Lord of Hatred expansion, which Blizzard has scheduled for the spring window tied to the anniversary coverage.
• Blizzard indicated that different flavours of the Warlock experience will appear across the series, suggesting unique mechanical implementations for each game rather than a one‑size‑fits‑all transplant.

Why this is significant

Introducing a brand‑new class across several titles is a major content commitment and a clear signal Blizzard intends to keep active development and updates rolling across its legacy and live titles. For Diablo II, adding a new class after many years refreshes the classic experience and offers veteran players new build possibilities. For Diablo IV, the Warlock’s arrival as part of an expansion underlines Blizzard’s roadmap for continued seasonal and expansion content.

Outstanding questions

• Exact mechanical differences between the Warlock implementations across games were not exhaustively detailed during the announcement.
• Pricing and inclusion specifics for Diablo II: Resurrected’s Warlock DLC vary by region and edition and were not fully itemised in the initial rollout notes.

Overall, the Warlock reveal is a centerpiece of Blizzard’s anniversary plans and a clear signal that the studio plans coordinated updates across the Diablo franchise in 2026.
