Recent Diablo IV leak chatter has shifted from “interesting rumor” to “multiple pieces of corroborating evidence,” centered on the still-unrevealed second class expected to arrive with the Lord of Hatred expansion. Between a higher-quality version of the same promotional artwork, reports of the image appearing in a PTR preorder flow, and datamined strings that appear to name the class, the community now has a much clearer picture of what Blizzard may be preparing.

This article breaks down what’s actually been seen, why it’s being taken more seriously than a typical screenshot leak, and what the class concept implies if the datamined “Warlock” name and the lore-adjacent “Vajari” references are both legitimate.

What’s supposedly being leaked: the second expansion class

At a high level, the situation is simple: Lord of Hatred is expected to ship with two playable classes. One of them, the Paladin, has been shown publicly as part of the expansion reveal. The second class has not been officially unveiled, and for a while players only had a silhouette and speculation.

The new leak material claims to show a second character standing alongside the Paladin in promotional art. The figure reads as a dark spellcaster archetype, casting a large red-and-black spell effect while also wielding an oversized weapon that resembles a two-handed sword.

Leak #1: a higher-resolution version of the same artwork

The first major credibility boost comes from a cleaner, higher-resolution version of the exact same composition that circulated earlier. The key point isn’t just that it “looks sharper,” but that the details appear consistent with a genuine source asset rather than a heavily upscaled image with obvious AI artifacts.

In the higher-quality version, the class’ magic effects are easier to read. The spell visuals are primarily red and black, with less of the purplish hue that was visible in earlier, lower-quality copies. That color language matters because it aligns with classic demonic theming in Diablo: blood-red energy, shadowed edges, and heavy contrast.

While none of this proves the class is real on its own, it does reduce the likelihood that the image is a quick fake built from a blurry original. It also gives more to analyze: weapon silhouette, stance, spell “shape,” and how the character is framed relative to the Paladin.

Leak #2: PTR sightings tied to the preorder/expansion page flow

The second major development is that multiple players have reported seeing this same background image while navigating a PTR flow related to expansion access. The described behavior is roughly:

• A player on the PTR clicks the Paladin (or otherwise hits an access check).
• The game prompts them to preorder or view expansion details.
• The expansion page displays the background art featuring the Paladin and the unrevealed class together.

What makes this more compelling than a single screenshot is the volume and format of the evidence: several posts reportedly show phone recordings of players scrolling through the page. Faking one screenshot is easy; coordinating multiple “different people” with consistent UI navigation and consistent art is harder, especially if the image matches the earlier leak exactly.

It’s still worth keeping expectations measured. PTR builds can contain placeholder assets, internal naming, or old test content. But seeing the same art appear in a functional in-client context is a meaningful step up from “someone posted an image on social media.”

The most direct “label” attached to the class comes from datamining claims tied to a PTR build, where a string resembling an internal page identifier reportedly includes the word warlock. The commonly repeated example looks like an internal UI reference for an expansion info page, ending in a class name token.

If accurate, that’s significant because it moves the conversation from “what does the art look like?” to “what is Blizzard calling it in the files?” Datamined strings can still mislead (cut content, test names, or deliberate obfuscation), but they often reflect real internal terminology.

There are also claims that the specific string was removed after it began circulating, though that point is harder to verify from the outside. Even if it was removed, that could mean anything from routine cleanup to a reaction to leaks.

The “Vajari” angle: why lore fans are paying attention

Alongside the “Warlock” naming, additional datamining chatter mentions “Vajari” (often spelled “Vizjerei” in Diablo lore discussions), one of the oldest mage clans in Sanctuary’s history. The clan is commonly associated with deep arcane study and, crucially for this leak, historical involvement with demon summoning and binding.

That matters because the leaked class visuals strongly imply demonic power use: red-black spell effects, a sinister casting posture, and a general “dark mirror” contrast to the Paladin’s holy archetype. A Warlock concept anchored in a mage clan known for demon-binding is thematically clean and easy to sell in an expansion marketing beat.

Even if the class isn’t literally “a Vizjerei,” Blizzard could still borrow the idea: a sanctioned demon-binder who uses Hell’s power against Hell, standing beside a holy warrior for a “light and dark” duo.

What the leaked class design suggests (if it’s real)

Assuming the art and naming are pointing in the right direction, there are a few plausible design pillars Blizzard could lean on for a Diablo IV Warlock-style class.

1) Demon subjugation as a core fantasy

The most exciting interpretation is a kit built around subduing demons rather than simply summoning generic minions. Instead of “summon imp” as a static skill, the class could revolve around capturing or binding demonic entities encountered in the world and converting them into temporary allies, empowered spells, or consumable resources.

There are multiple ways this could be implemented without breaking Diablo IV’s pacing:

• Temporary binds: defeat an elite demon, then bind its essence for a short-duration summon or buff.
• Essence siphons: harvest demon power to charge a high-impact spell (burst window gameplay).
• Choice-based bindings: pick one “bound demon” as a loadout modifier that changes how certain skills behave.

This would also help differentiate the class from Necromancer minions. The identity becomes “enslaving Hell’s power,” not “raising the dead.”

One of the most striking details in the leaked image is the weapon: it reads like a large sword, yet the character appears to handle it with one hand in the artwork. That could be pure artistic license, but it also hints at a hybrid archetype: a caster who fights closer to the action, using a heavy weapon as a conduit rather than as a purely martial tool.

If Blizzard goes that direction, the class could play like:

• Midrange spellblade: sweeping arcs that leave cursed ground or blood sigils.
• Drain-tank caster: sustain through leech-like mechanics tied to cursed targets.
• Execution windows: mark enemies, then “cash in” with a weapon-based finisher that detonates the mark.

This would also fit the “Paladin and Warlock side-by-side” marketing image: two characters who can stand in the thick of combat, one fueled by holy conviction, the other by stolen demonic force.

3) Red-and-black spell language: curses, blood, and shadow

Diablo IV’s visual readability is heavily tied to color and silhouette. A red-black palette suggests a blend of blood magic, shadow corruption, and infernal flame without stepping directly on the Sorcerer’s elemental identity.

Possible spell themes that match the leak’s visuals:

• Curses: debuffs that spread, amplify damage taken, or reduce enemy output.
• Blood rites: spend life to gain power, then recover it via drains or executions.
• Infernal brands: apply marks that detonate when conditions are met.

Why the “light class + dark class” pairing makes marketing sense

Even without any leaks, a Paladin plus a dark caster is a classic ARPG expansion pairing. It creates a clean contrast in trailers, key art, and class fantasy messaging. It also broadens the audience: players who want righteous melee and players who want forbidden magic both get a “headline” option.

Importantly, the leak art doesn’t necessarily imply the classes are allies in the story. Promotional art often shows classes fighting the same enemy for presentation purposes. The “opposing powers, same battlefield” visual is simply effective.

What to watch for next: the February 11 Diablo Showcase

The most practical takeaway is timing. With a Diablo Showcase scheduled for February 11 (tied to Blizzard and Diablo anniversaries), this is a natural moment for Blizzard to reveal a new class, clarify expansion details, and set expectations for upcoming seasons and PTR changes.

If the Warlock leak is accurate, expect any official reveal to focus on three things:

• Class fantasy: what power source it uses and why it exists in Sanctuary.
• Signature mechanic: a hook that differentiates it from Sorcerer and Necromancer.
• Combat role: whether it’s a backline caster, a midrange bruiser-mage, or a summoner variant.

Take a look at: what the roadmap mystery could mean for Diablo IV

Individually, each leak component has weaknesses. Artwork can be fabricated, PTR content can be staged, and datamined strings can be misleading. Together, though, they form a more coherent package than most one-off leaks:

• The same art appears across multiple sources and in higher quality.
• Reports place the art in a believable in-client context (expansion info background).
• Datamined naming aligns with what the art visually implies.
• Lore-adjacent references (Vajari/Vizjerei) fit the demon-binding theme cleanly.

The remaining unknown is implementation: even if the class is real and called Warlock, its moment-to-moment gameplay could be anything from curse-heavy support damage to a weapon-forward spellblade to a true demon-binder with controllable summons.

Frequently Asked Questions

Is the second Lord of Hatred class confirmed to be a Warlock?

No. Nothing here is official confirmation. The “Warlock” name is tied to datamining claims and could change before reveal.

Why do people think the leaked art is real?

The same background image has reportedly been seen in a PTR expansion/preorder flow by multiple players, and a higher-resolution version matches earlier leaks closely.

It’s a mage clan in Diablo lore associated with demon summoning and binding, which fits the leaked class’ red-black infernal spell theme.

Will this class be a summoner like Necromancer?

Not necessarily. The visuals and speculation suggest demon power use, but it could be more about siphoning and curses than permanent minions.

When might Blizzard reveal the class officially?

The February 11 Diablo Showcase is the most likely near-term moment for a formal announcement, given the timing and current leak momentum.
