Blizzard’s Diablo 30th Anniversary Spotlight was not just a celebration — it was a statement.
In one sweeping reveal, Blizzard announced the arrival of the Warlock class in both Diablo IV and Diablo II: Resurrected. For Diablo IV, the Warlock arrives alongside the upcoming Lord of Hatred expansion. For Diablo II: Resurrected, the Warlock headlines a full expansion titled Reign of the Warlock — the first new class added to Diablo II in over 25 years.
But the class reveal was only the beginning.
The Spotlight introduced an entirely new region, sweeping endgame redesigns, deep buildcrafting systems, the return of the Horadric Cube, long-requested loot filters, and major quality-of-life updates across both titles.
Sanctuary is entering a new era — darker, deeper, and far more customizable.

Diablo Warlock Class Cinematic Trailer – 30th Anniversary Reveal
The Warlock Arrives in Diablo IV
The Warlock in Diablo IV is described as the dark mirror of the Paladin. Where the Paladin embodies divine order and righteous light, the Warlock embraces infernal chains, curses, and demonic power.
Blizzard positioned the class as an anti-hero who bends the Burning Hells to their will. Rather than simply casting spells, the Warlock embodies vengeance itself — binding demons, sacrificing power for strength, and reshaping the battlefield through forbidden incantations.
This is not a traditional caster archetype. It is a class built around sacrifice, summoning, and corruption mechanics that aim to redefine Diablo IV’s power fantasy.
A full mechanical breakdown is scheduled for the Developer Update Stream on March 5, but even the early preview suggests a class built around aggressive resource manipulation and battlefield control.
Skovos — A New Endgame Region
The Lord of Hatred expansion introduces Skovos, one of the most lore-rich regions ever seen in Diablo IV.
Skovos appears steeped in the ancient history of Sanctuary’s progenitors. Marble cities carved with depictions of the Blessed Mother and Heavenly Father dominate the landscape, blending elegance with dread. At its center stands Temis, the expansion’s endgame capital.
Once players complete the expansion campaign, Temis becomes the primary hub for endgame activities. It is designed as a streamlined command post — visually majestic, but haunted by the whispers of ancient civilizations and Prime Evil influence.
Skovos is not just a location. It is a lore expansion that promises deeper exploration of Sanctuary’s earliest conflicts.
Endgame Reinvented — War Plans
One of the most ambitious systems revealed for Diablo IV is War Plans.
War Plans allow players to create a custom chain of up to five endgame activities. Instead of jumping between disconnected systems, players can build a personalized progression route including:
-
The Pit
-
Infernal Hordes
-
Helltides
-
Nightmare Dungeons
-
Lair Bosses
-
Kurast Undercity
The defining feature is customization. Activity trees can be modified to alter behavior. You could spawn The Butcher in every Pit run. Replace Helltide bosses with Duriel. Inject Bloodseekers into entirely different content.
War Plans hands control to the player. You design the chaos.
Echoing Hatred — Survival Without Limits
Echoing Hatred is introduced as Diablo IV’s ultimate stress test.
Triggered by a rare item called Trace of Echoes, the mode unleashes escalating waves of randomized enemies and multiple simultaneous bosses tied to Mephisto’s forces.
Difficulty scales infinitely. Rewards increase the longer you survive. Builds are pushed to their absolute limits.
This is not casual farming content. It is a pure mechanical and theorycrafting challenge.
Massive Skill Tree Overhaul
Every class in Diablo IV receives a fully overhauled Skill Tree with the expansion — even for players who do not purchase it.
Over 40 reworked nodes and 80 new options significantly expand build expression. Expansion owners gain access to 20 additional transformative variants.
Blizzard demonstrated this using the Sorcerer’s Hydra skill. Instead of small stat adjustments, players can now alter behavior entirely — changing damage types, attack patterns, or converting Hydras into frost-based variants.
The philosophy is clear: deeper theorycrafting and stronger character identity.
The Talisman, Charms & Set Bonuses
A brand-new Talisman system introduces Charms and Set Bonuses to Diablo IV.
Charms must be slotted into the Talisman to activate. Higher rarity Charms — especially Set Charms — unlock powerful bonuses when combined.
This system layers another dimension of optimization beyond traditional gear, adding more long-term progression depth.
The Return of the Horadric Cube
The legendary Horadric Cube returns to Diablo IV.
Once unlocked, it allows players to:
-
Transmute affixes onto items
-
Upgrade item rarity
-
Remove unwanted affixes
-
Convert common items into Uniques of the same type
This modernized version blends nostalgia with new systems, expanding item chase depth and crafting flexibility.
Diablo II: Reign of the Warlock Expansion
While Diablo IV moves forward, Diablo II: Resurrected takes a historic step of its own.
The Reign of the Warlock expansion introduces the first brand-new class to Diablo II in over 25 years.
The Warlock in Diablo II
Unlike the Necromancer’s undead armies, the Diablo II Warlock focuses on demonic binding, empowerment, and consumption.
Players can:
-
Summon up to three demons
-
Imbue weapons with infernal power
-
Curse and weaken enemies
-
Consume bound foes to absorb strength
The design emphasizes high-risk, high-reward aggression. It feels more volatile and destructive than any summoner archetype previously seen in Diablo II.
For longtime fans, this marks a monumental milestone.
Enhanced Terror Zones
Reign of the Warlock expands the Terror Zone system by allowing players to enhance specific Acts using tradable consumables.
This increases both difficulty and rewards while integrating directly into Diablo II’s player-driven economy. Enhanced Terror Zones also serve as preparation for the expansion’s new pinnacle encounter.
The Colossal Ancients — Pinnacle Endgame
The expansion introduces the Colossal Ancients, a new endgame boss fight tied to enhanced Terror Zones.
Blizzard describes it as a true pinnacle challenge — designed to push even optimized builds beyond comfort. For players who have conquered Uber Tristram repeatedly, this offers a fresh and formidable test.
Major Quality-of-Life Improvements Across Both Games
Both titles benefit from long-requested updates:
-
Loot Filters
-
Expanded Stash Tabs
-
Better item clarity
-
Inventory improvements
In Diablo II: Resurrected, players also gain advanced stash stacking and a Chronicle system to track collected items — adding a new completionist layer.
30th Anniversary Celebration — Voice the Warlock
Blizzard launched the “Voice the Warlock” contest as part of the anniversary celebration. Winners receive a trip to London to attend The Infernal Symphony, an official Diablo music concert.
Participants submit entries via Instagram using #WarlockChallenge and #DiabloContest.
Conclusion
The Diablo 30th Anniversary Spotlight was not simply a reveal – It was a roadmap.
In Diablo IV, the Warlock introduces a new dark power fantasy while Skovos, War Plans, Echoing Hatred, the Skill Tree overhaul, Charms, and the Horadric Cube push buildcrafting to unprecedented depth.
In Diablo II: Resurrected, Reign of the Warlock revitalizes a legendary ARPG with a new class, expanded Terror Zones, and a pinnacle boss encounter.
Two games. Two Warlocks. One evolving Sanctuary. Diablo is not standing still, it is transforming — and this may be the franchise’s darkest chapter yet.
