With Diablo 4’s hugely successful Season 15 slowly coming to an end, Blizzard is looking ahead to Season 16. The latest PTR introduces major changes, from expanded War Plans customization to new items that interact with Talisman sets, giving players a chance to test the additions and share feedback before launch.
Just like with most patches, class balance is also getting heavy attention in Season 16, with several changes that go beyond straightforward buffs and nerfs. Druid is undergoing a major rework of skill tags and Paragon bonuses, aimed at reducing its reliance on stacking multiple tags to maximize damage.
Paladin, meanwhile, is receiving a significant change to Aura Potency, which will now scale with bonuses from Aura skill ranks. This could create new opportunities for Aura-focused builds and give Auradin players something to look forward to.
Important: All changes outlined in the PTR patch notes are subject to change before Season 16 goes live.
Below, we break down the key changes for every class and explore what they could mean for builds currently played in Season 15.
Barbarian
One of Barbarian’s most significant Season 16 changes is the redesign of Aspect of Limitless Rage. Once a staple of top leaderboard builds, it lost much of its appeal in Season 15 following a heavy nerf and the arrival of powerful Runeword alternatives
Blizzard is now substantially increasing its damage bonus, but with an important restriction: only Fury generated by Basic Skills will count toward its effect. Builds that already use a Basic Skill could benefit naturally, while others would need to adjust their rotations to take advantage.
For builds focused on constant movement and channeling, such as the always popular Whirlwind, the Aspect likely won’t make the cut.
Aspect of Incendiary Fissures is also having its damage bonus doubled, which might inspire more Earthquake themed builds, like the famed Leapquake. Meanwhile, Double Swing’s base damage is doubling, and its Slice and Dice variant is losing its Cast Speed penalty
Rounding out the changes are improvements to Weapon Expertise, including fewer conditional requirements and better applicability against bosses. Rather than a sweeping overhaul, Barbarian’s changes largely focus on strengthening particular skills and giving players reasons to reconsider overlooked options.
Druid
Druid is receiving some of the patch’s most substantial changes, with Blizzard aiming to reduce the class’s reliance on stacking Skill tags to maximize damage.
For example, Claw’s Storm variant currently benefits from Werewolf, Shapeshifting, Storm, and Nature Magic tags. Under the new system, upgrades and variants will no longer grant Nature Magic or Shapeshifting tags; those will remain tied to the base Skill. Lightning Claw would therefore retain its Werewolf and Shapeshifting tags and gain Storm, but not Nature Magic.
To compensate, several Legendary Paragon Nodes are being reworked to support a broader range of builds. Thunderstruck becomes Howling Thunder and affects both Storm and Werewolf Skills, while Earthen Devastation becomes Devastation, benefiting Earth and Werebear Skills.
One change I’m less enthusiastic about is Ancestral Guidance. Its new effect empowers your next five Human Skill casts after spending 75 Spirit, replacing the Spirit-based Ultimate scaling that builds such as Cataclysm relied on.
Blizzard is also trying to give Resolve and Fortify more distinct roles. Several Earth Skills are losing their Resolve interactions in favor of other bonuses, including Overpower generation and consumption.
Spirit Boons are getting significant adjustments, too. Advantageous Beast stands out with its new 25% Deadly Strike Chance alongside 25% Movement Speed, making it the first time a class is getting native bonuses to Deadly Strike, which should be a powerful option for damage-over-time builds. Gift of the Stag, meanwhile, will grant 100 Maximum Spirit.
That additional Spirit could become particularly valuable with the redesigned Storm Shepherd set. Its two-piece bonus loses free casting and the stacking damage bonus of up to 80%, instead granting 40% increased Storm Skill damage and chances to Double or Triple Cast.
The five-piece bonus shifts toward resource scaling, granting Storm Skills 1% increased damage per point of Spirit when cast. This effectively takes over part of Ancestral Guidance’s former role for Storm builds. Combined with Gift of the Stag and items such as Melted Heart of Selig, it could offer substantial damage potential, though losing free casting makes resource management more important.
Whether these changes improve Druid’s standing remains to be seen. Broader Paragon support could help more builds find their footing, but losing Skill tags also narrows the Aspects and Unique interactions available to existing builds. The PTR will show whether those tradeoffs leave the class stronger—and more varied—overall.
Necromancer
While Necromancer isn’t receiving a rework on Druid’s scale, several changes could still have a major impact on existing builds. The most important among them is the redesign of Blood Moon Breeches, one of the staple Necromancer items.
Currently, these pants allow Summons to apply Curses while granting up to 60% increased Critical Strike Damage against Cursed enemies. That offensive power is especially valuable in a typically defensive equipment slot, which is why this item is a part of almost every Necromancer build.
Season 16 retains the Curse application, albeit at a lower chance, but replaces the damage bonus with 20–30% Damage Reduction against Cursed enemies. Builds relying on the Breeches will therefore lose a substantial offensive multiplier, although buffs elsewhere may help offset that loss.
Additional protection is welcome, but with defensive Legendary Aspects already competing for the slot, the redesign raises questions about how appealing the item will remain.
Other Uniques are getting changes that could encourage new setups. Gospel of the Devotee will empower all Basic Skills, including the one used to trigger its effect, while also receiving a higher damage bonus. The Mortacrux, another underused item, received a more dramatic redesign: it will passively consume nearby Corpses and, after consuming ten, empower the next base Core Skill with substantially increased damage.
Bug fixes could prove just as influential as these item changes. The Skeleton Mage Singularity upgrade will no longer allow more Mages than intended, removing an interaction used by top Summoner setups. Fixes to Blood Wave and other damage interactions could also change how these builds perform.
Elsewhere, several Core Skills and Legendary Paragon Nodes receive damage buffs, while Book of the Dead bonuses are being adjusted. Healing is being reduced across multiple sources, including Blood Orbs, Life Tap, and the Skeleton Warrior healing upgrade.
Taken together, these changes suggest a shift in where Necromancer gets its damage and survivability. Whether the new options compensate for lost multipliers and bugged interactions will be one of the key questions during PTR testing.
Paladin
Paladin is receiving several interesting changes in Season 16, with adjustments to Ultimates, stronger Zealot options, and a significant update to Aura scaling. Fortress’s Resolve damage bonus is being reduced and restricted to Juggernaut Skills, while Zenith’s Empyrean Edge variant will grant a larger Critical Strike Damage bonus for eight seconds.
Zeal gains more Lucky Hit Chance and increased damage for its Death or Glory variant. Zealot Oath also receives more damage and grants Damage Reduction at maximum Fervor. Its Fortify generation increases, but will now require Zealot Skill casts.
Supporting Aspects are changing, too. Jacques’ Fervor will grant a stronger general damage bonus per Fervor stack instead of Critical Strike Damage, at the cost of steadily draining Faith. Revelator’s Aspect will make enemies take progressively more damage from you as you hit them with Zealot Skills, up to 90%. A damage buff to Red Sermon rounds out the changes.
The headline adjustment, however, is Aura Potency. It will now amplify Aura values after accounting for Skill Ranks, rather than affecting only their base values. Blizzard describes this as a significant power increase, with reductions to certain Aura Potency sources intended to compensate.
This opens up more possibilities for using Auras offensively, so builds such as Auradin might return back into the meta.
Personally, the most interesting Paladin changes pertain to Advance. This Basic Skill doubles as a mobility tool, but has struggled to establish itself as the centerpiece of an endgame build.
The redesigned March of the Stalwart Soul boots will give Advance a higher damage bonus and an area cleave. Meanwhile, Cathan’s Dauntless Faith will allow its five-piece Afterimages to use Advance when it triggers Do or Die. Together, these changes could help turn Advance from a movement option into a build defining skill.
Finally, Arcadia is receiving a substantial defensive redesign. Rally will convert up to 50% of your Fortify into Barrier, grant up to 25% Damage Reduction, and have its cooldown halved. Barrier is especially significant for Paladins, since the class lacks natural sources of it, making this previously overlooked item worth reconsidering.
Rogue
Rogue continues to be among the strongest classes in Diablo 4, and its Season 16 changes focus on specific mechanics and items rather than a broader redesign.
The most significant Rogue change coming to Season 16 are the buffs to Shadow Imbuement. At the moment, Cold and Poison Imbue options dominate the Rogue meta, so improvements towards Shadow should open up more options and possibilities.
Repeated applications will now stack damage instead of refreshing the existing effect, and Infection explosions can also stack. Dark Dance will work when Dashing through enemies, Endemic gains the Cutthroat tag, and expired Shadow Play Infections will now explode.
Elsewhere, the Ferocity damage bonuses for Penetrating Shot, Rapid Fire, and Rain of Arrows are being reduced. Shadow Clone’s Sentry variant also gains the Trap tag, potentially opening up new interactions.
Several Unique weapons receive substantial buffs. Orphan Maker, the crossbow built around a Reload mechanic, is having its damage bonus nearly doubled. Skyhunter also gains a much larger damage bonus, making it worth testing for Rapid Fire builds affected by the Ferocity reductions. Meanwhile, Pitfighter’s Gull will boost all Grenade Skill damage alongside its improvements to Smoke Grenade.
As with Necromancer, bug fixes could be just as influential as the headline changes. Arrow Storms will properly benefit from Ferocity and Double Damage upgrades, while Rapid Fire’s Ruckus upgrade and certain Combo Point damage bonuses will function correctly. Shadow Clone also receives fixes to several Imbuement and item interactions.
Sorcerer
Sorcerer’s Season 16 changes focus heavily on Pyromancy, with Blizzard giving several Fire Skills some attention.
Incinerate receives one of the most notable reworks. Despite being a fan favorite, it has often struggled to compete with top builds. Part of that comes down to its stationary, channeled playstyle, which can feel at odds with Sorcerer’s otherwise fast-paced gameplay.
To make it more flexible, Blizzard is introducing Intensity. Incinerate will still build toward maximum damage as you channel, but its Intensity will persist for up to three seconds after you stop. This gives players a brief window to reposition and resume casting at full strength, rather than having to rebuild their damage every time they move.
Firewall’s Ring of Fire variant is getting another nerf. After its broad usefulness in Season 14 was narrowed to Pyromancy in Season 15, its damage is now falling from 300% to 100%. A longer duration and shorter cooldown partly offset that reduction, but its overall performance will need testing.
Inferno, meanwhile, gains its Pull effect by default, freeing its former upgrade to provide additional damage.
Flamescar is being redesigned around Incinerate’s new Intensity mechanic. At maximum Intensity, it will deal a portion of Incinerate’s damage to surrounding enemies without the previous additional Mana drain. Although the damage value is lower, the changed effect makes a direct comparison misleading.
Habaclava’s Cauldron is also changing. Much like Druid’s Storm Shepherd, its five-piece bonus loses free casting, replacing it with 50 Mana Regeneration. This makes resource costs relevant again.
Several upgrades involving Overpower are being adjusted, too, including those for Familiar, Meteor, Hydra, and Flame Shield.
Outside Pyromancy, Ball Lightning receives some welcome improvements. Strike of Stormhorn grants larger damage bonuses, while the Implosion variant lasts longer, loses its Mana cost, and receives a shorter cooldown.
Bug fixes could also affect familiar builds. Blue Rose will correctly trigger Lucky Hit effects, while Meteor’s Damage and Size upgrade will no longer apply its damage increase twice. Fixes to several Enchantment interactions should also make those effects more reliable.
Spiritborn
Spiritborn is in a solid position, although its endgame build variety remains limited. Season 16 focuses mainly on rebalancing existing skills and items, with some promising changes for less popular options.
Stinger, one of the top Spiritborn builds, receives several reductions. The skill’s base damage falls from 140% to 125%, alongside smaller damage bonuses from its upgrades. Counterattack’s cooldown will also only begin once its active effect ends, making continuous uptime harder to maintain without additional charges.
On the other hand, Razor Wings are getting interesting changes. Casting a Focus Skill will restore one charge, while casting an Ultimate restores all charges. Its base damage rises from 120% to 160%, and the Charge Cooldown upgrade will reduce its cooldown while spending all charges at once. The former Refund Charges upgrade becomes a Lucky Hit effect that can reduce one active cooldown, potentially allowing the skill to be used more readily.
Swarm of Storms Paragon Node increases the damage of Pestilent Swarm and Spirit Storm by an extra 20%, with Storm Feathers gaining an additional 50% increase. Glyphs are getting more flexible, with Talon granting Vulnerable damage instead of Lightning, and Jaded Plume changing Lightning damage to Eagle.
Among Unique items, Sunstained War-Crozier will grant Potency Skills an additional charge, making it worth considering for Razor Wings setups. Loyalty’s Mantle gains up to 60% increased damage for Skills of the matching Base Spirit, potentially making it more competitive with Harmony of Ebewaka, which receives a reduction to damage bonus.
Finally, a fix to Aspect of Supremacy will prevent it from exceeding its intended limit of 15 stacks. Since most top Spiritborn builds rely on this aspect, the correction could be more important than some of the listed balance changes.
Warlock
Warlock has dominated Season 15 following the extensive changes it received before launch. Blazing Scream has been a particular standout, combining exceptional damage, speed, and area coverage.
Season 16 aims to rein in some of that power while strengthening alternatives, particularly Hex and Abyss Skills.
Blazing Scream’s base damage falls from 130% to 115%, but the more consequential reductions affect its supporting items. Elegy’s damage bonus for additional Skull Splitter skulls will now be restricted to channeled variants, removing a major source of scaling for the build.
Further reductions come through Moloch’s Beating Flame, whose bonus per Volatility-empowered Skill drops from a maximum of 30% to 20%, alongside a reduction to Infernal Homunculus.
Together, these changes could dramatically lower Blazing Scream’s damage ceiling. Given the current performance of this build, however, I think these nerfs are justified.
Another popular build facing nerfs is Apocalypse. All variants receive reductions, but Annihilation stands out: its maximum stack count increases to 200 while its damage bonus per stack is halved. Players will therefore need twice as many stacks to reach the same bonus. Considering how quickly the build can generate them, this seems like a reasonable way to slow its damage ramp-up.
On the other side of the balance changes, Abyss Skills receive several improvements. Nether Step gains a faster animation, with a variant offering additional charges and Shadowform. Umbral Chains receives a substantial increase to its Periodic Chain damage, while the redesigned Overmind Paragon Node combines a large damage bonus against Crowd Controlled enemies with a way for Abyss Skills to generate Dominance.
Soul Shards are also receiving significant changes, particularly Mastermind. Recast Skills will no longer consume Shadowform, making it easier for Abyss builds to maintain its bonuses, including those associated with the Beru of Harash’s Shadow set.
Command Laalish becomes a Recast Skill, allowing players to reposition his Terror Realm while it is active. The Realm’s duration also increases by 50%, giving players more flexibility in longer encounters.
Unfathomable Fragment receives a substantial redesign. Laalish will increase Maximum Shadowform by four, while Non-Recast Abyss Skills gain 20% increased damage and no longer break Shadowform’s Stealth. However, each cast will consume one Shadowform stack, creating a different resource tradeoff.
Blasphemous Fragment shifts its damage bonus from Abyss Demonology to Abyss Summon Skills, while reducing Recast Skills’ Resource Costs and Cooldowns by 20%. Finally, Subjugation Fragment will allow Laalish himself to be consumed, opening up another potential interaction for builds using that mechanic.
Ritualist, meanwhile, has Valloch’s Wrath Regeneration bonus reduced from 100% to 50%. With Abyssal Fragment, Command Valloch will cause Hexed enemies to instantly take 100% of the Occult Abyss Skill’s damage, while kills will reduce active Occult Abyss Skill cooldowns.
Season 16’s patch notes introduce some ambitious reworks, touching everything from skills and items to class identity. PTR testing should reveal whether these changes take the classes in the right direction.
