Diablo 4 BlizzCon 2026 Twitch Drops Explained: Watch 6 Hours, Claim 3 Free Weapon Cosmetics

Diablo BlizzCon will begin at 10:15 AM on September 12th (Pacific Time), where hidden content for Diablo 4 Season 15 will be revealed, and Blizzard developers will be interviewed, hopefully bringing us some surprises.

Based on Patch 3.2.0 PTR, we anticipate Blazing Scream Warlock to be one of the strongest builds in D4 Season 15.

This build's exceptional performance stems from a series of class enhancements, powerful unique gear synergies, and Warlock's inherent advantage in converting Hellfire skills into devastating damage output.

This article will analyze in detail why Blazing Scream Warlock is so strong in Diablo 4 Season 15 and how to build it.

Reasons for Its Strength

Patch 3.2.0 PTR descriptions are almost entirely focused on enhancing Warlock, with dozens of skills receiving buffs or mechanic improvements. 

The most significant power boost comes from the unique weapon Elegy, which converts Blazing Scream into Arc Fiend skills. This transformation unlocks many powerful synergies that were previously unavailable.

When used in conjunction with Infernal Homunculus, you gain free access to all secondary lesser demon effects, including vulnerability, resource generation, enhanced wave damage, and additional slowing effects, significantly improving survivability. This single synergy alone can dramatically increase the build's damage output.

Meanwhile, in Season 15, many of Warlock's abilities can now be cast while moving, some bugs have been fixed, and ability cooldowns have been extended.

Furthermore, Blazing Scream Warlock benefits greatly from the season mechanics, one particularly powerful one allowing the build to gain bonus damage upon killing enemies, including Warlock's own demon, allowing these bonuses to stack and create massive damage multipliers.

Core Mechanics and Abilities

In D4 Season 15, the core of Blazing Scream Warlock revolves around casting a fiery demon skull that spins around the character for 10 seconds, dealing massive damage with minimal rage cost.

Orbital Scream variant, unlocked at level 15, transforms this skill into a continuously rotating area of hellfire that automatically clears hordes of enemies while maintaining the character's mobility.

The key synergy of this build relies on having at least five Hellfire skills in the skill bar to trigger the ripple effect, resulting in a massive damage bonus. Sigil of Subversion adds a layer of Lava Trail to Blazing Scream, along with an additional layer of damage over time.

For mobility, Nether Step is the primary movement skill, providing a decaying 60% damage reduction buff. Summon Abodian serves as a secondary movement skill, granting additional acceleration.

Demonic Smash, an upgrade to Rampage, unlocked at level 30, provides an additional movement skill that consumes Dominion Points to close distances or reposition.

Required Items

Blazing Scream Warlock requires several essential Diablo 4 items to reach its full potential. Let's take a closer look.

Elegy

This weapon is crucial for Blazing Scream Warlock, transforming Blazing Scream into an Arc Fiend skill and activating all Lesser Demon synergies, thus amplifying the build's power.

Infernal Homunculus

This weapon complements Elegy, providing all secondary Lesser Demon effects for free. These include: applying Vulnerable to increase enemy damage; Rampage for resource generation and self-regeneration; Volatility to enhance Hellfire skills; and Slow to improve knockback and survivability.

The Flames of Abaddon

The Flames of Abaddon is vital in the late game. This set allows you to transform into Demon Form, stacking Infernal Hunger over 5-10 seconds and converting it into Demonic Strength when attacking elite monsters or bosses.

Other

There are other available equipment options that players can choose based on their needs, primarily including: Tibault's Will (for resource recovery and damage output), Fists of Fate (for high damage fluctuations, which can improve average output), and Leoric's Crown (can be used in conjunction with Soul Splinters for additional power).

Stat Priorities

In Diablo 4 Season 15, you should prioritize increasing attack attributes. Critical Strike Chance should ideally be reached at 100%, followed by Vulnerable Damage Multiplier, and Core, Hellfire, and Demonology skill ranks.

Next, for defensive attributes, you should focus on Maximum Life, Resistances, and Armor. Season 15 has enhanced Resistances, making them more valuable than ever, as they provide more damage reduction.

Game Strategy and Output Rotation

The standard output rotation for Blazing Scream Warlock begins with casting Sigil of Subversion, then keeps Dark Prison active to defend against projectile attacks. Use Metamorphosis immediately after its cooldown, as it provides the highest damage multiplier in Warlock's skill set.

Then, you can use Nether Step to move through monsters and reposition yourself in combat. This skill also provides a 60% damage reduction buff, but it decays over time. For faster movement, use Summon Abodian.

This build excels at speed-running various content, including Helltides, Nightmare Dungeons, and general open-world events. Surrounding skeletons automatically lock onto and eliminate enemies, allowing you to focus on positioning and maintaining buffs.

This concludes our article on building Blazing Scream Warlock in Diablo 4 Season 15. While this build requires specific gear to reach its full potential, the visual impact and devastating combat experience it delivers are definitely worth it.

This is the current situation; more details will be available after Diablo BlizzCon. If you're interested, be sure to tune in to the livestreams on September 12th and 13th. 

Watching the live stream will also earn you some rewards. Watching for two hours will earn you a Serrated Skean Dagger, four hours will earn you a Corroded Cleaver Axe, and six hours will earn you a Tintinnabulation Two-Handed Mace. Let's look forward to it!

Diablo 4 Season 15 has adjusted Mythic Upgrade mechanic. Players can now directly upgrade an existing Unique item into a Mythic version while retaining its original stats, Tempering, and Masterworking, all while boosting its Unique Power.

However, Mythic items created via this recipe bear a special Crafting Mark, and you can only equip one such item at a time.

Therefore, the key consideration during the early-to-mid stages of Season 15 is: which Unique item should receive Mythic upgrade to yield the greatest boost in combat power? Usually, the answer is the core piece of gear that offers the most significant benefit to your current build.

What has Changed with Mythic Upgrades?

While Mythic Upgrades in Season 14 involved a high degree of randomness, D4 Season 15 allows players to directly upgrade an existing Unique item into a Mythic one.

Upon upgrading, the original item's Affixes, Tempering, and Masterworking are preserved, and Unique Power is increased by approximately 30%.

Consequently, it is better to farm a target Unique with strong stats first before performing Mythic Upgrade. Note, however, that you can only equip one Mythic item created via this recipe at a time; D4 Mythic items obtained through standard drops or other methods are not subject to this restriction.

How should You Choose Your First Mythic?

Since the supply of Sparks is limited during the early-to-mid stages of Season 15, your first Mythic upgrade should prioritize the core Unique item that provides the greatest benefit to your build.

When selecting a target, consider Unique Power's multiplier. A 20% effect might only rise to around 26% after upgrading - a relatively minor actual gain - whereas upgrading an effect with a high base multiplier yields a much more significant benefit.

Beyond the multiplier, consider whether Diablo 4 items directly contributes to your core damage output, how reliably its effect triggers, and whether the item's Affixes, Tempering, and Masterworking are of high quality. If these conditions aren't ideal, there is no need to rush into spending a Spark, even if the multiplier is high.

Upgrade Order

For the vast majority of builds, start by identifying the most important Diablo 4 Unique items in your current setup and comparing their Unique Powers, trigger frequencies, and impact on core damage output. Once you have identified your highest-priority target, farm a version with better stats, complete Tempering and Masterworking, and finally perform Mythic Upgrade.

After completing the first item, you can leverage this power spike to tackle higher-difficulty content. Faster mob clearing and progression speeds will improve the efficiency of acquiring subsequent gear and resources.

If you later obtain a stronger Mythic for the same slot, you no longer need to reserve your upgrade opportunity for that item; instead, you can shift your focus to the next high-value Unique in your build.

In this way, the priority for Mythic Upgrades shifts dynamically alongside your gear. Prioritize upgrading the item that offers the greatest benefit at your current stage, and only consider the next item once the current one has been replaced by a superior option.

Don't Rush to Use Your First Batch of Sparks

Although it is possible to acquire Sparks early in D4 S15, there is no need to perform a Mythic Upgrade immediately upon obtaining the resource.

If you haven't yet farmed your core Unique, or if the current version's key affixes and enhancement results are mediocre, it is better to continue progressing and farming gear. Since the upgrade preserves the item's current state, investing Sparks too early into a Unique that will soon be replaced yields little return.

The ideal time to upgrade is after you have locked in your build's core gear and possess a version of high enough quality to use reliably for an extended period. This ensures that your first Mythic Upgrade translates effectively into actual combat power.

How Should You Adjust if You Find Another Mythic Later?

The first Mythic you upgrade in D4 S15, doesn't have to occupy that slot forever.

If you subsequently find or craft a stronger Mythic that can replace your current piece, you can re-evaluate the remaining Uniques in your build and shift your upgrade target to the next most beneficial slot.

For example, you might initially prioritize upgrading Unique with the highest damage multiplier; once that slot is replaced by a stronger Mythic obtained through drops or crafting, you can then look at the item with the second-highest multiplier or the one that most significantly affects your build's rotation.

Therefore, the priority list for Mythic Upgrades is not static; it develops as your gear improves. Upgrade the item offering the highest current benefit first, and address the next item only after securing a replacement.

Why does This Change Mid-Game Progression?

In the past, Mythics were rarely included in mid-game builds because consistently obtaining specific items was difficult during that phase. 

With the introduction of targeted Mythic Upgrades in Diablo 4 S15, players can upgrade core Unique items into Mythics much earlier. This facilitates an earlier transition into a mid-game setup, providing a reliable boost to combat effectiveness during that phase.

For your first Mythic upgrade in D4 Season 15, prioritize a Unique item that offers a Unique with a high-value Unique Power multiplier, contributes consistently to core damage output, and has a solid base. Choosing the right target ensures a significant power spike in the early-to-mid game, thereby accelerating your subsequent progression.

Death Trap Rogue build in Diablo 4 Season 15 continues Grenade Trap gameplay from the previous season, with no major changes to its core skills and equipment system.

However, the changes to Melted Heart of Selig in Season 15 make resource management easier for this build, giving Death Trap Rogue more stable survivability in high-level pits. With proper resource and cooldown management, Death Trap can maintain a consistent release rhythm and deal extremely high damage.

Next, EZG.com will provide a detailed introduction to this Diablo 4 Death Trap Rogue build, including core equipment, skill mechanics, and practical gameplay, helping you quickly complete your build in Season 15.

Mechanics

The core of Death Trap Rogue build in Diablo 4 Season 15 revolves around energy spend, energy restore, and ultimate cooldown. When using ultimate skill, Beastfall Boots consume all energy and increase ultimate damage based on the amount consumed.

Meanwhile, Preparation reduces ultimate skill's cooldown based on energy consumed, decreasing it by 5 seconds for every 75 energy consumed. After skill activation, resources need to be quickly replenished using Aspect of Aftermath and resource generation on D4 gear.

Aspect of Aftermath restores energy based on ultimate skill's rank. Death Trap Rank is primarily obtained from Scoundrel's Leathers, Saboteur's Signet, and Charm set pieces; the higher Death Trap Rank, the higher energy Recovery.

It's recommended to keep Death Trap cooldown under 35 seconds. Diablo 4's Greater Affix cooldown reduction can be obtained from Gloves, Eyes in the Dark, and Misericorde.

Taking significant damage and running out of energy will noticeably slow down the entire skill rotation; shorter cooldowns allow for energy recovery and energy drain.

Gear

Maximum energy is one of the core attributes of Death Trap Rogue. Melted Heart of Selig in Season 15 is suitable for this build because it doubles Rogue's primary resource and prioritizes energy for damage taken, while significantly reducing that damage, giving this build good survivability in high-level Diablo 4 pits.

As a result, energy in D4 not only sustains Death Trap skill rotation but also becomes an important defensive resource. The cost is a 75% reduction in maximum life, so other Diablo 4 items should prioritize maximum energy, resource generation, and the core affixes required by the build, rather than simply stacking maximum life.

Misericorde and Eyes in the Dark provide cooldown reduction and damage multiplier, which are important components of Death Trap rotation.

Saboteur's Signet grants a Size Increase, although it doesn't extend the area of ​​effect of Death Trap in Diablo 4 maps. However, damage multiplier, vulnerable, and weakened it provides all apply to Death Trap.

D4 grenade mechanic is a crucial component of this Death Trap Rogue damage rotation. Through Explosive Triggers, Death Trap benefits from Stun Grenade Multipliers, Opportunist's Aspect, and Explosive Multipliers.

Defensively, Helmet can choose Debilitating Toxins paired with a Poison Imbuement Corrosive Ring. When Poison Imbuement is activated, it creates a Poison Aura around the character, continuously inflicting Poison status on nearby Diablo 4 enemies, thus reliably triggering damage reduction from Debilitating Toxins.

Death Trap Rogue can utilize Black Soulstone, Pain, and Anguish, focusing on damage, damage reduction, and attack speed ​​and critical strike chance respectively, but each comes at a cost.

Leoric's Crown enhances the inserted Diablo 4 Gems and increases Splinters' effectiveness, but it occupies a Helmet slot, so its value depends on the specific attributes and gear setup in Season 15.

Seal of the Diamond Mind can utilize both Phoba of the Sightless and Phoba of Applied Alchemy. Phoba of the Sightless resets Concealment after each Ultimate cast, allowing it to continuously participate in the skill rotation and helping to restart Death Trap when energy is low.

Phoba of Applied Alchemy primarily refreshes Detonation Dash, while also providing damage and damage reduction. If you don't have Seal of the Diamond Mind yet, you can skip Applied Alchemy and use Sea Lord's Fine Gloves as a temporary solution.

Runes

Zan and Mot passively provide Dark Shroud, allowing you to add Dash to your Diablo 4 skill bar. Death Trap Rogues don't have enough base CDR to sustain Infinistep, so Dash is one of their primary movement skills.

Yul and Vex provide additional skill ranks. Skill Ranks increase Death Trap damage and Aspect of Aftermath energy recovery, making them highly beneficial for Death Trap Rogues.

Paragon Boards

In D4, Death Trap Rogues use five Paragon Boards: Start, Deadly Ambush, No Witnesses, Danse Macabre, and Eldritch Bounty, focusing on enhancing Death Trap and grenade-related damage.

The chosen Glyphs are Devious, Canny, Versatility, Explosive, and Ambush. Explosive and Ambush further amplify the damage gains from Explosive Triggers in Death Trap.

Other Glyphs primarily supplement Rogue's general damage and skill buffs, ensuring consistent output for the entire build in farming Diablo 4 items and boss fights.

Mercenary

Raheir is chosen as Hired, primarily for providing additional defensive capabilities. In higher Torment difficulties, enemy damage increases significantly, and Raheir can provide extra protection through Valiance, Raheir's Aegis, and Bastion.

Combined with damage reduction mechanics like Melted Heart of Selig and Debilitating Toxins, Death Trap Rogue can more easily maintain energy and skill rotation in higher levels of D4 Season 15.

For Reinforcement, choose Aldkin and further increase defense through Field of Languish, supplementing your Diablo 4 character's damage reduction capabilities in combat and maximizing survivability in high-difficulty environments.

In-Game Operation

At the start of a Diablo 4 battle, use Poison Imbuement to spread Poison Aura to more enemies, triggering Aspect of Debilitating Toxins. Next, use Concealment to activate Phoba of the Sightless set bonus and gain critical strike chance through Calculation, while also providing up to 310% damage multiplier.

Then use Smoke Grenade to gain critical strike chance through Silhouette. Afterward, cast Death Trap. Once Death Trap enters cooldown, the set bonus will reset Concealment.

Concealment doesn't need to be used immediately. Wait until Unstoppable effect ends before casting it to ensure more efficient skill effect coverage. Shadow Step and Dash are used for map movement. Death Trap Cycle also helps refresh Dash, allowing the character to maintain a high movement speed.

Death Trap Rogue still maintains good damage output and survivability in Diablo 4 Season 15. As long as resource cycling runs smoothly, it can deliver consistent combat power in high-level Pit. If you enjoy high-burst, fast-paced rogue gameplay, this build is worth a try.

Diablo 4 Season 15 is set to launch on September 15, but Patch 3.2.0 PTR clearly did not showcase everything the season has to offer.

Blizzard has explicitly stated that some S15 content is being held back for BlizzCon reveal. As the event approaches, a screenshot - purportedly showing a new map - has begun circulating, revealing the locations of Kingsport and Duncraig in the western region of Sanctuary.

This raises a major question: Is Season 15 content Blizzard is saving for BlizzCon related to these western map areas?

Content Held Back from PTR

What is certain is that Season 15 will arrive alongside 3.2.0 update, bringing with it a suite of systems and Diablo 4 items already tested on  PTR, such as Soul Splinters, Challenge Dungeons, and Overland Ambush events.

Challenge Dungeons deserve particular attention. Blizzard has clarified that the encounters featured in PTR were primarily designed to test underlying systems, and the official S15 release will feature different content.

Even players who fully experienced 3.2.0 PTR have not yet seen the complete scope of Season 15.

A more direct indication comes from Blizzard's own explanation regarding PTR. The team explicitly stated that they did not want all upcoming Season 15 content to be revealed before they had the chance to present it at BlizzCon.

Consequently, BlizzCon's role regarding S15 likely goes beyond standard seasonal promotion. Diablo 4 still holds back unrevealed content, and the scale of this hidden material has become the subject of intense speculation.

New Map Leak

Amidst this anticipation, a screenshot - purportedly of D4 world map - has begun circulating within the player community.

The currently accessible areas of Diablo 4 cover only a portion of Sanctuary world map, leaving vast, unexplored spaces to the west.

The leaked image reveals Kingsport and Duncraig situated west of the existing zones, surrounded by a large, as-yet-unopened continent. Based on the map in the leak, this western region lies in the same general direction as classic locations like Westmarch, Lut Gholein, and Tristram; iconic sites such as Mount Arreat could also potentially appear within this western territory in the future.

Currently, there is no evidence proving the screenshot originated from within Blizzard, nor is there confirmation that Kingsport and Duncraig will open immediately in Season 15.

However, what makes this leak particularly noteworthy is its timing: it coincides with Blizzard's official statement that there is still Season 15 content being held back for BlizzCon.

Kingsport in S15?

This naturally leads to a primary speculation: Could Kingsport and Duncraig be among the content Blizzard withheld from PTR?

The timing certainly makes a connection plausible. PTR only tests specific mechanics; Blizzard explicitly noted that Season 15 still holds content reserved for BlizzCon; and the screenshot of the new map surfaced just before the convention.

If BlizzCon ultimately reveals Kingsport or Duncraig, a direct link would be established between this map leak, the content omitted from PTR, and S15 launch scheduled for two days later.

However, a degree of caution is still warranted.

Blizzard has never announced that Kingsport or Duncraig are part of Season 15, nor have they confirmed the addition of large, permanent map zones for the season.

Given the scale of past D4 content, an entirely new region of Sanctuary is more reminiscent of a major expansion - or perhaps part of a long-term update roadmap.

Therefore, the most reasonable approach for now is to wait and see if these two locations officially appear at BlizzCon, and then determine whether they relate to S15, the next phase of the storyline, or a future expansion.

Western Expansion

Even if the leaked map proves authentic, it should not necessarily be interpreted as Blizzard opening up the entire western continent all at once.

New expansions or major updates typically introduce one region at a time, gradually expanding the map through subsequent content releases.

This approach is also better suited to the long-term live-service model of Diablo 4. Kingsport and Duncraig could serve as the initial entry points into the western region, while locations such as Westmarch, Lut Gholein, Tristram, and Mount Arreat could be reserved for future storylines or expansions.

Therefore, the true significance of this leak extends beyond just one or two cities. If Kingsport does indeed make it into D4, it suggests that the game's map of Sanctuary may be poised to expand further westward, while also leaving room for numerous classic locations to return to the main narrative.

BlizzCon Reveal

Blizzard has confirmed that BlizzCon 2026 will take place in Anaheim on September 12 and 13, with Season 15 officially launching on September 15. This makes BlizzCon essentially the final major official announcement window before the new season goes live.

For Diablo 4 players, the most pressing question is clear: what content does S15 hold that wasn't revealed during PTR?

Systems, D4 items, and features like Soul Splinters, Challenge Dungeons, and Rebirth are already known; the real suspense lies in what Blizzard has deliberately kept under wraps.

If Kingsport or Duncraig appear in official BlizzCon footage, the credibility of the recently leaked map screenshots will skyrocket, and Season 15 could even serve as a bridge to the next major story arc or expansion.

Of course, until Blizzard makes an official announcement, Kingsport, Duncraig, and the western continent remain speculative details based on leaks.

What to Watch?

New maps, Kingsport, Duncraig, and whatever else Blizzard is hiding regarding Season 15. If these names appear in official BlizzCon footage, the credibility of the leaked map will be significantly bolstered.

It remains to be seen whether S15 will be a standard season or if its new D4 items and content will subtly lay the groundwork for future storylines, classes, or even the next expansion.

The most certain fact right now is simple: PTR didn't reveal everything about D4 S15, Blizzard saved the remaining content for BlizzCon, and the new season launches just two days later. 

So, it all comes down to one thing: are Kingsport and Duncraig merely a splashy pre-BlizzCon leak, or are they the real ace up the sleeve for Season 15?

While the official announcement for Diablo 4's third expansion is likely still some time away, players are already speculating about what the next new class might be.

For Diablo series, new classes have always been a major draw for expansions. From Crusader and Necromancer to the classes added post-launch in Diablo 4, every new addition impacts build choices, gear requirements, and the overall game meta.

If Blizzard chooses to preview Expansion 3 at a future BlizzCon, the new class will undoubtedly be a highlight.

However, since Blizzard hasn't confirmed which class will be included in the third expansion, the best approach right now is to analyze Diablo 4's current roster, classic series classes, and unexplored gameplay styles to determine the most likely candidates.

Monk

Monks are one of the classic classes players frequently ask to see return.

In Diablo 3, Monk featured high-speed movement, close-quarters combos, and a distinct martial arts style. Its overall pacing differed significantly from traditional heavy melee classes like Barbarian, making it instantly recognizable.

In reality, however, Monk's potential return depends on Spiritborn. Spiritborn already features high-mobility melee combat, rapid repositioning, and numerous skills centered on spirit energy - gameplay elements that closely resemble Monk's style.

Furthermore, Spiritborn's tribal and spirit-based themes overlap with design elements previously associated with both Monk and Witch Doctor.

If Blizzard were to simply port D3 Monk directly into the game, the two classes would likely suffer from overlapping roles.

That said, Monk could still return if it undergoes a significant overhaul. This might involve emphasizing fist weapons, rapid-fire strikes, and defensive counters, while establishing a new resource loop based on D4 items - effectively refocusing the class on its core martial arts identity.

Amazon

Amazon faces fewer hurdles than Monk.

Diablo 4's Rogue already covers bow combat, agile movement, and certain ranged damage playstyles; consequently, a traditional Bow Amazon would easily overlap with the existing Rogue class. However, Amazon's identity isn't defined solely by the bow and arrow.

Javelin, Spear, and Lightning-based Amazon builds can still form a distinct class identity. This is particularly relevant given that Diablo 4 currently lacks a class with a gameplay system fully centered on spears, javelins, thrown weapons, and their associated Diablo 4 items.

This actually creates an opening for Amazon. If the developers decide to bring back this classic class, the most logical approach wouldn't be to create another ranged archer; instead, they could emphasize spear charges, javelin throws, spreading lightning attacks, and precise mid-range strikes.

This strategy would preserve Amazon archetype familiar to D2 players while clearly avoiding the gameplay territory already covered by Rogue.

Witch Doctor

Witch Doctor is another highly distinctive class of Diablo 3. Its unique combat style - defined by poisons, pets, summons, and eerie spells - stands out, yet this design feels a bit crowded within the current Diablo 4 landscape.

Necromancer already possess a mature summoning system and command corpses, curses, and a vast array of dark magic, while Spiritborn covers elements like spirits, nature, and tribal culture. Consequently, no matter which direction Witch Doctor takes, it risks overlapping with existing classes.

Therefore, rather than a direct recreation of D3 Witch Doctor, the developers are more likely to deconstruct its defining features - such as poison spells, curses, totems, or unique summoning mechanics - and recombine them into a distinct new class.

Blood Knight

If the developers choose not to look to D2 or D3 for inspiration, a Blood Knight-style class becomes an interesting option.

Blood Knight archetype has already been utilized in Diablo Immortal, and since Diablo 4 already features numerous vampire enemies, blood-based abilities, and dark religious themes, such a design would fit seamlessly into the world of Sanctuary.

More importantly, it is easy to establish a combat style for Blood Knight that differs significantly from the current classes.

Its gameplay could revolve around mechanics like health consumption, life-stealing, sustained regeneration, blood-based skills, and short-term transformations. It could utilize two-handed weapons or polearms, with D4 unique items further enhancing a high-risk, high-recovery melee combat loop. 

While Barbarian emphasizes strength, weaponry, and direct strikes, and Necromancer leans into death, corpses, and summoning, Blood Knight could center its mechanics on a cycle of trading health for damage and then reclaiming that health through combat.

If the developers can craft mechanics that are sufficiently distinct, this class has the potential to stand apart from the existing roster.

Shaman, Dark Knight, and Spellsword

Of course, the new class for Expansion 3 does not necessarily have to come from Diablo's past roster.

Spiritborn has demonstrated the developers' willingness to create entirely new class concepts for Diablo 4, making completely original designs a distinct possibility for the future.

For instance, a Shaman class could be built around totems, elemental spells, and short-duration summons, further distinguishing itself from Druid's shapeshifting and nature magic.

A Dark Knight could wield greatswords and heavy armor, emphasizing blocking, charged attacks, or high-risk melee combat to create a heavy-hitting playstyle that is more stable and rhythm-focused than that of Barbarian.

There is also significant potential for a Spellsword. Currently, Sorcerer relies primarily on pure spellcasting, leaving a gap for a class that truly blends large melee weapons with magic. Enchanted weaponry, elemental slashes, defensive spells, and close-range spellcasting could all serve as core elements of such a class.

More daring directions cannot be ruled out either; after all, Spiritborn proved that Blizzard is willing to push the boundaries of Diablo class design, so Expansion 3 need not look to the past for answers.

As D4 roster grows, it becomes increasingly important for the new class in Expansion 3 to avoid overlapping with existing playstyles.

Whether the choice falls on a classic class like Amazon or a new concept like Blood Knight or Shaman, the key lies in delivering a combat experience that is genuinely missing from the current lineup. Only with a sufficiently distinct identity can the new class truly serve as a core selling point for the expansion.

Blizzard has released the full schedule for BlizzCon 2026, with the main events being Diablo: Developer Update and Diablo IV: What's Next. Both events will take place on the main stage and will each last 45 minutes. During this time, Blizzard will showcase some content that they intentionally removed from Season 15 PTR.

Normally, we see lengthy patch notes weeks in advance, but this time, the development team seems to be keeping some trump cards in mind. This article will show you the specific schedule for BlizzCon 2026 and related content for Diablo 4 Season 15.

About BlizzCon 2026

According to the official BlizzCon 2026 schedule, there are two main events and a series of other related events. Details are as follows:

Diablo: Developer Update will be held on the main stage at approximately 2 PM Pacific Time on Saturday, September 12th, lasting 45 minutes.

It's important to note that Blizzard hasn't explicitly stated that this presentation is exclusively for D4, meaning they may also announce Diablo Immortal, Diablo 2: Resurrected, or other titles in the series.

Diablo IV: What's Next will be held on the main stage around 8 PM on Sunday, September 13th, lasting 45 minutes. Generally, Blizzard adding future prospects to a game's title quickly generates high player anticipation, and this time is likely no exception.

In addition, there will be other Diablo 4-related segments. Saturday will feature Art of Darkness: Behind Diablo IV's Cinematics, and Sunday will host a Battle.net 30th anniversary keynote, with CD Projekt Red as a special guest.

Season 15 Confirmed Content

Soul Splinters

This is a brand new socketable item that perfectly embodies Blizzard's classic design philosophy. It provides a significant power boost, but also comes with equally significant negative effects.

Legacy Uniques

Diablo 4 Legacy Uniques make a strong comeback, including items like Leoric's Crown, Nemesis Bracers, and Stone of Jordan, all taken from previous games and reappearing with a brand new look.

Rebirth System

Diablo 3's Rebirth System returns, allowing players to carry over their seasonal characters to the next season, avoiding starting from scratch each time.

Challenge Dungeons and Overland Ambushes

These two new event types sound intriguing. Challenge Dungeons are randomly appearing portals in the open world leading to boss battles, giving you new objectives in Helltides. Overland Ambushes, on the other hand, will make you a target - you'll receive a 30-second warning before demons hunt you down.

However, it's important to note that Blizzard has explicitly stated that Season 15 PTR is only for testing the underlying systems, and the final version will differ. This is essentially a euphemism for saving the best for BlizzCon 2026.

Why Blizzard Is Keeping Secrets This Time?

Before D4 Season 15 3.2.0 PTR test server opened, Blizzard issued an unusually direct warning: the features included in the test server differed from what players typically expected because they wanted to share more content at BlizzCon and didn't want all of Season 15's content to be revealed prematurely.

This meant that August PTR test server didn't contain the complete season content. Players experienced Soul Splinters, Legacy Uniques, Mythic and Unique Charms, Rebirth, Challenge Dungeons, and several underlying systems, but some of the actual season content remained hidden behind the scenes at BlizzCon.

Normally, we see the full roadmap months in advance, including patch notes and detailed information about PTR test server. So why break with tradition this time?

Building Hype Smart Way

By keeping the details under wraps, they not only successfully fueled the enthusiasm of the player community but also bought themselves ample time to develop the game. PTR test server showcased a glimpse of Season 15, but Blizzard is clearly saving the best for BlizzCon.

This is a carefully crafted strategy - giving core players ample time to test and provide feedback on core mechanics, while reserving the most visually stunning content for the highly anticipated event.

Getting Time for Polishing

Furthermore, there are practical considerations. Feedback on Soul Splinters on PTR was mixed; some players felt the resource penalty was too high, while others thought the balance was perfect.

By delaying the release of flashy content, Blizzard can focus on refining core mechanics based on player data, while reserving the most compelling content for the event with the largest audience.

Learning From Past Mistakes

Frankly, Blizzard has experienced some setbacks in content releases in the past. Over-promising and failing to deliver has cost them dearly. This time, they've acted more wisely.

Revealing confirmed content, testing uncertain aspects, and unveiling the big bombshell at the highly anticipated event. While this isn't some sophisticated strategy, it's certainly gratifying to see  Blizzard actually putting it into action.

Could Switch 2 Finally Appear?

This remains a hot topic. Despite increasing speculation about a September release, Blizzard has yet to officially announce that D4 will be coming to Switch 2.

If they do intend to, I think Diablo IV: What's Next event would be the perfect opportunity to announce Switch 2 news.

Viewing Rewards

Players watching the livestream at home can also earn some physical rewards, which can be claimed through Twitch and YouTube from September 12th to 15th. Two hours of viewing will earn you Serrated Skean dagger, four hours will unlock Corroded Cleaver axe, and six hours will earn you Tintinnabulation hammer.

This concludes our introduction to BlizzCon 2026. September 13th is a day to watch, as Diablo IV: What's Next presentation will be held on this day. It's crucial for Season 15, as the remaining important details of the game will be revealed there.

Interested players should remember to schedule their time to watch BlizzCon 2026 livestream and see what surprises Blizzard has in store for us.
