Diablo 4’s Season 15 questline should no longer be blocked by an early Splinter of Prime Evil pickup. A new update addresses an issue that let some players obtain the item before the seasonal story intended them to receive it. Because Prime Evil Powers are meant to arrive as a quest reward, getting a Splinter ahead of that step could leave a character unable to properly complete the central seasonal questline.
The preventative fix is welcome, but it does not retroactively repair every character caught by the problem. Players whose quest progress was already affected will need to use a workaround: create another character in the same game partition and complete the seasonal questline with that new character. Doing so unlocks Prime Evil Powers for every character in that partition.
What the Season 15 quest bug changed
The core issue was not merely that an item showed up early. In a seasonal action RPG, reward order can be tied directly to progression flags: invisible checks that determine whether the game recognizes a quest objective, grants a system unlock, or permits the next stage of a storyline. Here, the Splinter of Prime Evil was apparently obtainable before the questline expected it to be, while Prime Evil Powers were reserved as the story’s reward.
That mismatch created a progression failure. A player could have the Splinter, but the quest’s intended reward state would not resolve as designed, preventing proper completion of the seasonal narrative. The update stops the bad sequence from happening to additional characters, which is the most important immediate repair.
However, the developer note makes an important distinction: preventing the bug is not the same as resetting progress for players already affected. In practical terms, a patch can close the door on a faulty trigger without automatically rebuilding every character’s prior quest state. That is why the workaround remains necessary.
The workaround: match the affected character’s partition
For an affected character to gain access to Prime Evil Powers, players are instructed to make a new character within the same partition, then finish the Season 15 questline on that character. The available partition examples are Normal versus Hardcore, and Normal versus SSF.
“Partition” matters here because the unlock is shared only within the relevant grouping. A completion in one partition will not necessarily help a character housed in another. Before starting over, players should check exactly where their blocked character resides and create the replacement character accordingly.
What “Normal,” “Hardcore,” and “SSF” mean in this context
- Normal refers to the standard character partition described in the workaround.
- Hardcore is treated as a separate partition from Normal for the purpose of this unlock.
- SSF, or Solo Self-Found, is also identified separately from Normal in the instructions.
The essential takeaway is simple: do not assume that any new seasonal character will solve the issue. It must be made in the same partition as the character that encountered the broken quest state.

A practical recovery checklist
- Confirm that the character was affected by receiving a Splinter of Prime Evil before the seasonal questline awarded Prime Evil Powers.
- Identify the affected character’s partition: Normal, Hardcore, or the relevant SSF grouping.
- Create a new character in that same partition.
- Complete the Season 15 questline on the new character.
- Return to the original character and check for access to Prime Evil Powers, which should be unlocked across that partition after completion.
This is not an ideal remedy. It asks players to repeat seasonal story progression on another character rather than restoring the blocked character’s quest state directly. Still, it provides a defined path forward rather than leaving those accounts permanently stuck.

Horadric Cube affix reroll issue is also fixed
The same update addresses a separate problem involving the Horadric Cube. Players had encountered a bug where four affixes could not be rerolled through the Cube. An affix is a modifier attached to an item, generally the sort of property players pursue or replace while refining a build. Rerolling is therefore an important process for anyone trying to adjust item properties toward a desired result.
That functionality has now been corrected, but the patch does not reimburse resources players may have spent while the system was malfunctioning. The fix prevents the problem going forward, yet it does not undo earlier unsuccessful attempts or replace consumed materials.
That limitation resembles the seasonal quest repair in one respect: the update is primarily preventative. It improves the current rules and systems, while the remedy for earlier damage is narrower. In the quest case, there is a character-based workaround; in the reroll case, wasted resources remain lost.
Splinter stacking remains the conspicuous unanswered request
Although the quest blocker and Cube reroll problem have been addressed, the update does not change the way Splinters stack. Player discussion has repeatedly focused on the inability to stack these items, with frustration continuing after the patch.
Stacking is a basic inventory-management feature: rather than occupying separate slots with each individual copy of an item, identical items can combine into a single stack with a quantity count. When frequently collected items do not stack, they can create more inventory clutter and more manual handling. That is why a request that may sound minor on paper can become a persistent quality-of-life concern during a season.
There is no indication in the available update details that a stacking change is planned, nor is there a timetable for one. For now, players should treat the situation as unchanged: the questline blocker has a fix, the Horadric Cube reroll issue has been corrected, but Splinter stacking has not been added.
What this patch means for Season 15 players
Players beginning the Season 15 storyline after the update should be able to progress without encountering the premature-Splinter issue that blocked completion. That is the clearest benefit of the change.
Players already trapped by the bug have a more involved route, but they do have one. Completing the seasonal questline on a new character in the matching partition should provide Prime Evil Powers to all characters in that partition, including the affected one. The requirement is inconvenient, especially for anyone who had already invested substantial time in the original character, but it establishes a workable recovery path.
The larger lesson is that seasonal progression systems depend on reward sequencing as much as on the rewards themselves. When an item arrives before the quest state that is supposed to grant it, the player may appear to have gained something early while actually losing access to the progression the item was meant to represent. This patch restores that sequence for future characters; the workaround is the bridge for those whose progression had already fallen out of order.
