Having your Diablo 4 seasonal quest stuck may be related to using a Splinter of a Prime Evil too early. The issue affected Season 15, known as Season of Hell’s Legacy, preventing some characters from progressing.
Blizzard addressed the bug with patch 3.2.3, released on October 14, 2026. However, the update did not automatically restore quest progress for characters already affected.
Blizzard’s official workaround involves creating another character in the same partition and completing the seasonal questline. This process unlocks Prime Evil Powers for all characters within that partition.
What Caused the Diablo 4 Seasonal Quest Bug?
The bug occurred when a character used a Splinter of a Prime Evil before completing the seasonal questline.
This action could prevent the character from progressing through the remaining seasonal quests. As a result, affected players could also lose access to Prime Evil Powers, a key feature of Season 15.
The Splinters are part of Season of Hell’s Legacy. They connect to the powers of Diablo, Baal, and Mephisto, alongside their related seasonal progression systems.
The problem was not caused by internet connectivity or server access issues. Instead, it involved a bug affecting quest progression and character unlocks.
Blizzard confirmed this specific issue in its official patch 3.2.3 notes.
How to Fix a Stuck Seasonal Quest in Diablo 4
Players who encountered this bug before the update must follow Blizzard’s recommended workaround.
Here’s what you need to do:
- Identify your affected character’s partition. Check whether the character uses Normal or Hardcore mode and whether Solo Self-Found is enabled.
- Create another seasonal character in the same partition. Make sure both game-mode settings match those of your original character.
- Complete the Season 15 questline. Progress through the seasonal quests normally using your new character.
- Return to your affected character. Check whether Prime Evil Powers became available after completing the questline.
Both characters must belong to the same partition. Blizzard distinguishes Normal from Hardcore and regular characters from Solo Self-Found (SSF) characters.
Solo Self-Found is a separate gameplay category with its own progression restrictions.
For example, completing the questline with a Normal character will not unlock powers for a Hardcore character. The same restriction applies when comparing SSF characters with those outside that category.
Once completed, the seasonal questline unlocks Prime Evil Powers for every character in the matching partition.
Did Diablo 4 Patch 3.2.3 Fix the Bug for Everyone?
Patch 3.2.3 prevents new cases of this bug, but it does not repair previously affected quest progress.
Installing the update will not automatically restart the stuck character’s seasonal questline.
Blizzard’s workaround provides access to Prime Evil Powers through a shared partition unlock. However, it does not promise to restore the original quest’s progress or resolve unrelated progression issues.
Therefore, the original character may still have an incomplete quest even after accessing the seasonal powers.
Patch 3.2.3, build 73883, launched on October 14 for PC, PlayStation, and Xbox.
Other Fixes Included in Diablo 4 Patch 3.2.3
The update also introduced fixes for bosses, items, and other Diablo IV systems.
The main changes included:
- Tyrael and Baal: Tyrael’s spawning position could make collecting Baal’s loot difficult after defeating the boss.
- Sandstone Golem: The boss could fail to respawn after a player’s death in the Horadric Library.
- The Countess: The boss could pass through the fog wall in the Forgotten Tower, preventing encounter progression.
- Horadric Cube: Certain affixes could not be rerolled, including Barrier Generation, Impairment Reduction, +Healing, and Critical Strike Damage.
- Necromancer: Some enemies failed to drop Unbroken Bones during the Call of the Underworld class quest.
Blizzard also included general stability, performance, visual, and user interface improvements.
What If Your Diablo 4 Seasonal Quest Is Still Stuck?
First, confirm whether your problem involves using a Splinter of a Prime Evil before completing the seasonal questline.
If your issue is different, Blizzard’s workaround may not resolve it. Other progression bugs can have separate causes and solutions.
Also, verify that your new character belongs to the same partition as the affected character. Make sure you completed the entire seasonal questline before checking Prime Evil Powers again.
If the powers remain unavailable, review Blizzard’s official patch notes. You can also report the issue through the official Diablo IV forums.
Include your platform, character details, affected quest, and troubleshooting steps already attempted. This information helps distinguish the known bug from other progression problems.
Avoid reinstalling Diablo 4 or changing network settings specifically to address this bug. Blizzard has not connected this issue to internet connectivity.
