Diablo 4: Lord of Hatred Expansion — All New Content, Classes, and Features Revealed

Diablo 4's second major expansion, Lord of Hatred, drops on April 28, 2026, and Blizzard has been steadily revealing what players can expect. The expansion brings one of Diablo's most iconic villains — Mephisto, the Lord of Hatred himself — to the center stage, adds a full new act set in the city of Caldeum, introduces a new character class, and overhauls the game's crafting systems in ways the community has been requesting since launch.

The Story: Mephisto Returns

Lord of Hatred picks up directly after the events of Vessel of Hatred, with Mephisto having escaped his soulstone imprisonment and begun corrupting the ancient city of Caldeum. The expansion's story act spans roughly 12-15 hours and introduces new supporting characters who grapple with the nature of hatred and whether it can be weaponized against its own source. Blizzard has promised the most ambitious narrative Diablo 4 has delivered to date.

Caldeum as a setting is a callback that will delight longtime Diablo fans — the city featured prominently in Diablo III's Act II and is one of the series' most storied locations. Blizzard has rebuilt it from scratch for Diablo 4's engine, reimagining it as a sprawling Middle Eastern-inspired metropolis now twisted by Mephisto's corrupting influence.

The New Class: What We Know

Blizzard has been careful to avoid fully revealing the new class ahead of launch, but datamines and official teasers point to a Duelist-style fighter who combines swift melee attacks with a unique 'Hatred' resource system that mirrors the expansion's themes. The class is described as high-risk/high-reward — building Hatred meter through aggressive play and expending it on devastating finishers that scale with how much you've accumulated.

Horadric Crafting System Overhaul

Perhaps the most significant quality-of-life addition in Lord of Hatred is the revamped Horadric Crafting system. Blizzard is finally reintroducing the large, complex affix numbers that the Diablo series is known for — the millions and billions of damage that made Diablo 3's endgame so satisfying. The new crafting bench allows players to combine materials to add, remove, or modify specific affixes on legendaries and uniques, giving build-crafters a level of control over their gear that Diablo 4 has sorely lacked.

Season 9 launches simultaneously with the expansion and is free for all players. The seasonal theme this year involves Mephisto's corruption spreading to the seasonal realm, with a new progression system that rewards players for purging corrupted zones. Season 9 also includes a new seasonal questline that serves as a prologue to the Lord of Hatred expansion story.

Pricing and What's Included

Lord of Hatred is priced at $39.99 and requires the base game to play. It does not require Vessel of Hatred (the first expansion) to purchase, though the story builds on its events. A Deluxe Edition at $59.99 includes cosmetic extras: a class-specific mount, an armor set, and a 20-level battle pass boost. All seasonal content remains free.
