What the official overview establishes

Blizzard’s expansion material places the story in Skovos and frames Lord of Hatred as a major Diablo IV content release.

It also supplies the expansion context for Paladin and Warlock, while exact skills, systems and itemization remain separate version-sensitive topics.

How to research the expansion

Use the official overview for campaign and class context.

Check current patch notes and product pages for live availability, feature changes and ownership details.

Do not infer a build ranking from an expansion announcement alone.
