Diablo 4 S13 bugs: Warlock, Resolve & Sorceress hotfix

Intro: three major bugs and a hotfix in S13

In his latest video, Rob2628 breaks down the latest upheavals of Season 13. A recent patch introduced several critical bugs simultaneously, and some of them are downright spectacular. The Warlock ends up dealing negative damage on its Eviscerate build. The Resolve Masterwork bug is back, making some classes nearly immortal. And the Sorceress Ball Lightning lost its core skill ranks, forcing Blizzard to push an emergency hotfix.

Each of these issues deserves a closer look. Spiritborn players will probably recognize the Resolve bug, since it already appeared in the past. For the Sorceress, Blizzard confirmed that the loss of ranks is indeed a bug, not a design decision. A fix has been announced.

The Necromancer is also affected by the same negative damage bug after the patch. Leaderboards are temporarily unavailable, but their return is expected later today. In short, S13 is off to a rough start on the technical stability side.

Here is a breakdown of each bug, class by class.

Warlock bug: Eviscerate deals infinite negative damage

Since the last hotfix on Eviscerate, the Warlock skill is displaying completely broken behavior. The principle is simple: Eviscerate deals Bleed damage based on previously dealt damage. Except the scaling effect spiraled out of control, generating absurdly negative numbers on screen. The concrete result: one-shotting every pack in Pit 150, bosses included, with negative damage values scrolling on loop.

The Warlock is finally capable of clearing Pit 150 competitively. The current rank 1 runs at around a 4-minute clear. The problem: this performance is built on a bug, not on solid design. The class animations remain too slow, the gameplay lacks fluidity, and this infinite scaling does nothing to address the sluggish feel that has been there since launch. Fixing a bug without addressing the root issues will not transform the class in the long run.

The negative damage phenomenon does not only affect the Warlock. The Necromancer also benefits from broken synergies tied to Bloodlands, with negative numbers visible on screen during Pit 150 speed runs in around 5 minutes. Both classes are in a similar situation: seemingly impressive performances built on unstable mechanics that Blizzard will need to fix quickly.

Resolve Masterwork bug: every class becomes immortal

Another major bug has resurfaced with the patch: the Resolve Masterwork bug. The principle is simple, and those who lived through Lord of Hatred remember it well. When you masterwork your Resolve stacks, and more precisely when you hit a triple crit on Masterwork, they do not stay at 5 per piece. They climb to 12. Per piece. This is exactly the same bug that hit the Spiritborn two years ago. The patch apparently reintroduced it for everyone.

Combining this bug with the Resolve glyph and the Glynn's Anvil Aspect which grants 6% multiplicative Damage Reduction per stack, the numbers become absurd. Players have already reached 72 Resolve stacks. At that level, with 6% multiplicative per stack, you approach 96% permanent Damage Reduction. The video shows a Paladin at 72 stacks. He tanks everything without flinching. Nikico posted on X a Toughness of 67 million, and current projections suggest some will surpass 200 million. Every class can reproduce this. No need for Life, no need for Dodge Chance. Just fully tempered Resolve stacks.

The advice is clear: do not waste your materials trying to hit that Masterwork triple crit on your Resolve stacks. This bug will be fixed, that is a certainty. The math does not add up: going from 5 stacks to 12 after a single Masterwork is exactly the signal that triggers an emergency hotfix. The Spiritborn had its 18 stacks per piece during Lord of Hatred, people were running low on Life regen and cycling infinite damage. Today every class can reach that immortality, but the developers' intent has clearly not changed on that point.

The patch fixed several bugs, sure, but it introduced just as many new ones in the process. This Resolve bug is just the second in a series that the patch apparently created.

On the Sorceress side, Blizzard did not take long to react.

Sorceress hotfix: Ball Lightning loses its core skill rank

The Sorceress nerfs deployed at the start of the patch triggered an uproar on Reddit. A massive discussion emerged the day before, and it turns out those nerfs were not intentional. Blizzard confirmed a hotfix is being prepared to restore the situation. The Sorceress will therefore regain her usual power, and the Pit 150 runs that were circulating, like Akurite blowing through the tier in 4 minutes before the bug, will become the norm again.

Two distinct points need clarification. First, the movement speed loss on Teleport. That change is intentional and will remain. Certain interactions between Meteor Enchantment and Overpower were generating clearly excessive mobility, and Blizzard considers that a bug to fix, not a feature. The second point, however, concerns Ball Lightning which was no longer recognized as a core skill after the patch. That behavior is a confirmed bug, and the hotfix will correct it.

Concretely, Ball Lightning will regain its 72 core skill ranks. The fix was not yet live at the time of writing, but Blizzard indicated it would arrive "soon". The formula is known, the timeline remains vague, but the direction is clear.

These fixes arrive in a context where Pit 150 leaderboards are moving at breakneck speed.

Pit 150 leaderboard and power creep: all classes at the top

This level of widespread power echoes a problem already seen in Diablo II. When everyone reaches the same difficulty ceiling, the gap between classes vanishes and progression loses meaning. Players no longer see the negative damage as content to master, but as a broken wall. Demand is logically rising for a Pit 200 or Tower 200 to restore depth to the endgame. Even the Necromancer, with no particularly identified build, seems to be cooking something serious in the community rankings.

On the Warlock side, the situation goes beyond simple bugs. The standard Apocalypse build, meaning no exploits or snapshots, now shows damage around 2,000 billion, a progression of roughly five tiers in very little time. The most optimistic predictions talk about 2-minute clears on the Warlock in the near future, while it already runs at 3 minutes currently. Bob (build) is clearing Pit 150 with the double snapshot, but runs have already been completed without that mechanic.

The Rogue received a fix, but Umbral has not yet been reactivated. The Paladin, meanwhile, is progressing and now reaching Pit 140. The Spiritborn regains its skills after their reactivation. In total, four classes are comfortably clearing Pit 150 in community leaderboards, with times around 5 minutes for several of them. The meta is evolving fast, and this is clearly not over.

Should you exploit these bugs? Tips before the fixes

Credit to Dom, who shared the planner and identified the Rampage / Eviscerate / Bleed combination at the origin of the bug. The overflow mechanic pushes damage into infinite negative values, which literally one-shots everything in existence. The Necromancer is in the same situation. This is not an optimized build, it is an overflow bug, and it will be fixed.

On the Sorceress side, the hotfix is on the way. Based on available information, the class should recover runs in 3-4 minutes in Pit 150, with Ball Lightning climbing back toward 70 ranks. If you play Sorceress, keep an eye on the video description: the link to the fix is at the bottom.

On the infinite Masterwork Toughness bug: it does effectively allow every class to become immortal without needing to stack Life, Dodge, or Damage Reduction. Unless you are playing full giga gear Barbarian style, where resistances still matter. But actively exploiting this bug carries a concrete risk. Resolve stacks and Temper behavior will be in the crosshairs of the next fix. Building an entire build around this is playing against the clock.

The Tower is coming back online in beta within a few hours. It is the right moment to test what works, before the hotfix resets the counters. Enjoy it while it is still there.
