Diablo IV players are getting their next major update today as Blizzard prepares to host a Developer Update Livestream focused on the upcoming Warlock class and the future of the game’s seasonal content.
The stream takes place March 5 at 11 a.m. PT (20:00 CET) and will provide the most detailed look yet at the Warlock class arriving with the Lord of Hatred expansion on April 28, 2026.
Blizzard has teased deep dives into gameplay systems, lore, and the direction of Season 12.
Warlock Class Reveal
The main highlight of the livestream will be a full breakdown of the Warlock, a demonologist-style class tied to the Vizjerei bloodline.
According to Blizzard’s preview, the stream will cover:
-
Warlock origins and lore
-
Core demonology abilities
-
Skill tree structure
-
Occult-themed talents
-
Class mastery systems
The Warlock introduces dark magic mechanics centered around summoning, curses, and demonic control — a playstyle many Diablo players have been requesting since launch.
A cinematic teaser released ahead of the livestream also hints at the class’s connection to Mephisto’s growing influence in Sanctuary.
Season 12 Preview
Alongside the class reveal, Blizzard is expected to discuss Season 12, the next seasonal cycle for Diablo IV.
Early hints suggest the season could include:
-
Killstreak-style mechanics
-
Bloodied item systems
-
skill tree adjustments
-
balance changes based on PTR testing
Season 12 is expected to arrive before the Lord of Hatred expansion launches later this spring.

The expansion will continue the story of Mephisto and introduce:

-
additional endgame progression
Blizzard has positioned the expansion as the next major step for Diablo IV following its seasonal content roadmap.
