'Reign of the Warlock Expansion' with game elements and dark fantasy setting.

Reign of the Warlock Expansion - What’s New

Reign of the Warlock is the biggest structural update to Diablo II: Resurrected since release. It introduces a brand-new playable class, expands endgame progression, and adds long-requested quality-of-life features that modernize how the game feels without changing its core identity.

This overview covers the main additions: the Warlock class, new itemization (uniques, runewords, sets, and endgame jewels), Terror Zone updates, a new high-end encounter, Chronicle tracking, stash upgrades, and wider platform support.

New Playable Class: The Warlock

The Warlock becomes the eighth playable class in Diablo II history. Built around dark arcane mastery and demonic influence, the class adds fresh build diversity and new theorycrafting routes for Ladder and endgame play.

  • First new Diablo II class in 25+ years
  • New skill trees focused on dark magic, binding mechanics, and destructive casting
  • Distinct playstyle that complements (rather than replaces) classic class identities
  • New build experimentation for early Ladder progression and high-end farming

New Items & Gear Additions

Reign of the Warlock expands the item pool with new uniques, runewords, sets, and a new item type: Grimoires (Warlock off-hand items). It also introduces new endgame rewards tied to the Colossal Ancient encounter and new progression items tied to Worldstone mechanics.
