Diablo 4 Patch 3.2.3 Fixes Season 15 Quest Locks and Horadric Cube Reroll Bugs

Summary

Diablo 4 Season 15 Patch 3.2.3 arrives on October 14, 2026, with targeted fixes for some of the season’s most frustrating bugs. The update addresses a Seasonal quest progression lock caused by Splinters of Evil, broken Horadric Cube affix rerolls, and several boss encounter issues. It also improves Baal loot pickup and the Necromancer class quest, helping players optimize their builds and manage their Diablo 4 Items more effectively, although some community-reported problems remain unresolved.

1. Splinters of Evil Bug Fixes a Major Seasonal Progression Block

One of the most important changes in Patch 3.2.3 concerns the Splinters of Evil questline bug. In Season 15, players are normally expected to complete the Seasonal questline before obtaining and selecting different Splinters. Each Splinter unlocks a separate reputation board, helping players progress toward Prime Evil Powers and their endgame bonuses.

However, a bug allowed players to use a Splinter before completing the required questline. This could lock the character out of further quest progression and prevent the player from unlocking Prime Evil Powers.

The patch fixes the underlying logic issue to stop this bug from happening again. There is one important limitation, though: the fix does not automatically restore quest progress for characters already affected.

Players experiencing this problem should:

• Create a new character in the same game partition.

• Complete the Seasonal questline on that character.

• Unlock Prime Evil Powers for characters within that partition, including the previously affected character.

This workaround matters for players who have already invested significant time in their Season 15 characters.

2. Horadric Cube Reroll Fix Makes Gear Optimization More Reliable

The Horadric Cube is another major focus of Patch 3.2.3. Previously, certain affixes could become difficult or impossible to replace during rerolling, limiting players’ ability to optimize their equipment.

The affected affixes include:

After the fix, players can use the corresponding Tuning Prisms to target and replace these affixes. For example, Pragmatic Tuning Prism can be used against Impairment Reduction, while Aggressive Tuning Prism targets Critical Strike Damage.

However, early community testing mentioned in the report suggests that the Critical Strike Damage fix may not cover every situation, particularly certain Seals. Players should verify the result on their own gear rather than assuming every reroll issue has been eliminated.

3. Baal Loot Pickup and Boss Encounters Get Improvements

Baal farming is an important activity for Season 15 players pursuing Mythic Uniques. Previously, Tyrael’s spawn position could obstruct Baal’s dropped loot, making items harder to collect. The problem was especially inconvenient for players using gamepads, who often needed to move closer to an item to pick it up.

Patch 3.2.3 improves the loot pickup experience, reducing this frustration during Baal farming.

The update also addresses two boss encounter issues:

• Sandstone Golem: The boss could fail to respawn after a player died during combat in the Horadric Library.

• Countess: The boss could pass through the fog wall in the Forgotten Tower, disrupting the encounter.

These fixes should make the affected activities more consistent and reduce interruptions during endgame progression.

4. Necromancer Quest and General Performance Improvements

Necromancer players also benefit from a fix to the Call of the Underworld class mechanic quest. Previously, not all monsters dropped the required Unbroken Bones, making the quest take longer than intended.

With this issue addressed, completing the quest should be less frustrating for players progressing through the Necromancer’s class mechanics.

The patch also lists general improvements involving stability, performance, visuals, and the user interface. However, the available notes do not specify exactly which performance problems will improve, so players should wait for further testing before assuming that every reported issue has been resolved.

5. Which Diablo 4 Season 15 Problems Remain?

Although Patch 3.2.3 addresses several important bugs, it is not a complete solution to every Season 15 complaint.

The Splinter stacking problem is particularly relevant to players collecting Prime Evil Powers. Splinters have a stack limit of one, and duplicate drops cannot be collected, potentially wasting valuable resources. The report also notes complaints about being returned to town after entering Waking Nightmare from Helltide and performance issues when multiple Warlocks appear in the same area.

Because the patch notes do not specifically confirm fixes for these problems, players should not assume they will disappear after updating.

Final Thoughts

Diablo 4 Patch 3.2.3 is a focused bug-fix update rather than a major content expansion. Its most meaningful changes address Seasonal quest progression, Horadric Cube rerolling, Baal loot pickup, boss encounter reliability, and the Necromancer class quest. Players affected by the Splinters of Evil bug should pay particular attention to the workaround, since the update prevents the problem from recurring but does not automatically repair existing quest progress. Players looking to optimize their builds can also explore cheap Diablo 4 Items as they continue progressing through Season 15. For the remaining Season 15 issues, further developer updates may still be needed.
