What’s changing in Diablo IV’s next expansion endgame?

The upcoming second expansion is positioned as a major shake-up to endgame progression and, more importantly, how builds are created and customized. While many details are still unrevealed, Blizzard’s early descriptions and brief gameplay snippets point to four headline additions: a loot filter, a substantial skill tree rework with skill variants, the return of the Horadric Cube as a crafting hub, and a new Talisman system that introduces set-style bonuses without tying them directly to your gear slots.

This article breaks down what’s been shown, what’s strongly implied, and the key questions that will determine whether these changes meaningfully expand build variety or simply add more layers to the existing power chase.

What we know from Blizzard’s description

Blizzard’s messaging frames these updates as “new and improved systems” that enable deeper customization and more variety across all classes. The specific highlights called out so far include:

• Major skill tree reworks with new skill variants for every class
• Level cap increases, implying more points and more room for specialization
• A loot filter to make desired drops easier to spot
• “With Lord of Hatred,” the ability to unlock bonus skill variants for each class
• A “fresh take” on crafting via the Horadric Cube
• A new Talisman system that enables set bonuses

It’s also important context that these additions are not described as replacing everything already in Diablo IV. Systems like enchanting (stat rerolls), aspects, tempering, and masterworking are expected to remain, though some may be adjusted to fit the new structure.

Loot filter: visibility tool or automated salvaging?

The loot filter is the most straightforward feature on paper, but the implementation details matter a lot. In Diablo IV’s current endgame, once you’re deep into higher difficulties, many players effectively treat large portions of the loot pool—especially rares—as salvage fodder. In some cases, the game already reduces friction by making low-value drops less relevant.

Two likely directions for the loot filter

• Highlighting and hiding rules: A classic ARPG filter that changes what you see on the ground and how it’s emphasized (colors, labels, priority).
• Filter-to-salvage automation: A more radical approach where filtered-out items are automatically converted into materials.

Auto-salvaging sounds convenient, but it can create balance pressure. If filtering equals faster runs (because you return to town less and spend less time sorting), then using a filter becomes effectively mandatory, and the “best” filters become part of the meta in a way that can narrow player choice rather than expand it.

What would make the loot filter feel best

The healthiest outcome is that a filter helps you see what you want, while the underlying item ecosystem becomes more interesting. If more rarities and affix combinations remain useful deeper into endgame, the filter becomes a customization tool rather than a bandage for an overly noisy loot pool.

Skill tree overhaul: the real build-crafting revolution

Based on what has been shown, the skill tree rework is likely to have the biggest immediate impact on build diversity. The key shift is that trees appear to be less about passive nodes and more about deep customization inside each skill.

One of the clearest details is that skills can be ranked up to 12 points (at least for non-ultimate skills, based on what’s been shown). That’s a dramatic change from the current structure and aligns with a level cap increase.

The big question is whether higher ranks do more than just scale damage and reduce cooldowns. Today, ultimate skills in Diablo IV often gain an additional effect when fully invested (for example, a meaningful bonus that changes how the skill fits into a rotation). If regular skills adopt a similar “milestone” structure at certain ranks, investing deeply into a single ability could become a defining build decision rather than just a numeric upgrade.

Potential milestone models that would make sense:

• Rank milestones (for example, a special modifier at mid investment and another at full investment)
• Unlockable mechanics that change targeting, resource behavior, or secondary effects
• Build-enabling conversions that shift how the skill scales (such as different damage types or different resource interactions)

New upgrade layout: side paths and a central variant choice

The shown layouts suggest two “side” upgrade paths with circular nodes (likely smaller, more traditional modifiers) and a central path featuring boxed nodes that represent skill variants. The variant choice appears to be the most transformative part, with three options for many skills and at least one example showing four options.

In practice, this could function like a modernized version of older ARPG rune systems: you still choose the base skill, but your variant selection can significantly change what the skill does, how it behaves, and even what element it uses.

Skill variants: element swaps and functional redesigns

The clearest example shown so far is a Sorcerer ability where a familiar lightning projectile behavior can be replaced by a variant that changes the element and the way the skill is deployed. Other glimpses suggest additional elemental remixes (such as alternate-element versions of familiar summons or channels), but the important takeaway is that variants are not just “+X% damage” style upgrades.

If variants are broadly available across the entire skill roster, this could dramatically increase the number of viable archetypes by letting players:

• Match skill elements to their chosen scaling and itemization
• Change delivery mechanics (projectile vs. ground placement vs. persistent effect)
• Open up new synergies with aspects, uniques, tempering recipes, and paragon choices

Bonus variants tied to Lord of Hatred

One particularly interesting line is that Lord of Hatred unlocks additional skill variants across each class. That suggests variants may be split into tiers—baseline options available to everyone, plus extra options gated behind expansion progression or a specific unlock path.

If done well, “bonus variants” can be a meaningful long-term goal because they create new build identities rather than simply adding raw power. If done poorly, they risk turning into mandatory unlocks that invalidate baseline versions.

Horadric Cube: a crafting hub with multiple systems

The Horadric Cube’s return is loaded with expectations because of its history. What’s been indicated so far is that the Cube is not a carried inventory item—it appears as a fixed station in town (or multiple towns), acting as a hub for “crafting systems” (plural).

What the trailer suggests

In the brief footage shown, an item is placed into the Cube and combined with rune-like components to produce a transformed result. That strongly implies the Cube will be used for recipes that:

• Combine items and materials into new outcomes
• Allow targeted transformations (turning one thing into a different thing)
• Potentially enable rerolls or conversions that are distinct from enchanting

Diablo IV already has several upgrade layers (enchanting, aspects, tempering, masterworking). The Cube needs a clear niche to avoid becoming just another menu. The most promising niches are systems that do something current crafting cannot do well, such as:

• Item-type conversions (changing the identity of an item rather than just its affixes)
• Resource transmutation (turning excess materials into scarce ones with meaningful tradeoffs)
• Recipe-based deterministic crafting that lets players work toward a goal without pure RNG
• Build-enabling infusions that interact with skill variants, enabling new scaling or mechanics

Because the Cube is described as containing crafting systems, it’s reasonable to expect several recipe categories rather than a single function.

Talisman system: set bonuses without gear-set lock-in

The Talisman system may end up being the sleeper hit of the expansion because it introduces set-like bonuses through a separate interface rather than occupying your armor slots. What’s been described is a UI element with six outer slots that feed into a central effect, producing bonuses based on the combination of inserted components.

How it appears to work

The components placed into the Talisman look like new farmable items with rune-like symbols. In at least one shown example, the inserted pieces display class-themed markings, suggesting there may be class-specific components alongside more general ones.

The biggest unknown is the rule system:

• It could be set thresholds (for example, 2-piece and 4-piece style bonuses)
• It could be pattern-based (specific combinations unlock specific effects)
• It could be synergy stacking where each piece contributes a modifier and the center effect amplifies them

Build implications: enabling forbidden combinations

The most exciting teaser is gameplay showing a Druid in a bear-form ultimate state using lightning abilities that are normally restricted, implying the Talisman can break or rewrite form/skill constraints. That’s a fundamentally different style of power than “more damage,” because it changes what a build is allowed to do.

If many Talisman bonuses follow this design philosophy, expect a wave of new archetypes built around:

• Cross-tag interactions (skills behaving as if they have different tags or elements)
• Form flexibility (casting options normally locked out)
• New skill behaviors (altered animations and effect shapes that change gameplay flow)

Rarity and chase potential

Another major unknown is whether Talisman components have tiers or rarity levels. If they do, that adds an entirely new chase layer to endgame: hunting not just for gear, but for the exact high-tier Talisman pieces that complete a combination.

That also creates interesting endgame routing questions: do certain activities, bosses, or regions specialize in dropping certain component families? If yes, the Talisman system could become a new reason to diversify your farming instead of repeating a single best activity.

How these systems might interact with existing progression

Even without confirmed overhauls to current systems, it’s easy to see how the new expansion features could cascade into the established build pipeline:

• Skill variants change what your core skills do, which changes which aspects and uniques are best.
• Higher skill ranks increase the opportunity cost of spreading points thin, encouraging more specialized builds.
• Horadric Cube recipes could provide new ways to target upgrades, potentially reducing friction when a build needs a specific breakpoint.
• Talisman bonuses may enable new interactions that make previously niche items suddenly best-in-slot.

The overall direction suggests Blizzard is aiming to increase build identity by letting players “lock in” a playstyle through variant choices and Talisman combinations, while still leaving room for item chase and optimization.

Because so much is still unknown, a few details will determine whether these systems land as meaningful build-crafting improvements or just additional complexity.

Loot filter key questions

• Can it hide items, highlight items, or both?
• Will it support custom rules or only presets?
• Does it interact with salvaging, and if so, how?

Skill tree key questions

• Where do passives go if they’re not in the skill tree?
• Do skill ranks include milestone effects, or are they mostly numeric scaling?
• How hard is it to respec variants and ranks?
• Are bonus variants purely expansion unlocks or earned via endgame progression?

Horadric Cube key questions

• How deterministic are recipes (fixed outcomes vs. RNG pools)?
• Are recipes gated behind activities, bosses, or reputation-style progression?
• Does the Cube create new currencies/materials, or mostly consume existing ones?

Talisman key questions

• Are components class-locked, class-weighted, or fully universal?
• How many combinations exist, and are they discoverable in-game?
• Do components have rarity tiers and upgrade paths?
• Are bonuses mostly power increases, or do they change gameplay rules?

Frequently Asked Questions

It hasn’t been confirmed. A traditional filter usually hides or highlights drops, while auto-salvage would be a much bigger gameplay and balance change.

Are skill variants just elemental swaps?

Some shown variants do change elements, but the bigger promise is that variants can also change how a skill functions, which could reshape rotations and synergies.

Is the Horadric Cube something you carry like in Diablo II?

Based on what’s been shown, it appears to be a fixed crafting station in town rather than an inventory item you bring into content.

Do Talismans replace gear sets?

They seem to deliver set-style bonuses through a separate slot system, which could avoid forcing you into specific armor pieces while still enabling “set” effects.

Will these changes affect every class equally?

Blizzard’s wording suggests the reworks and variants apply across all classes, but the real impact will depend on how many variants each skill gets and how build-enabling the Talisman bonuses are.
