Blizzard raising Diablo 4 Prime Evil Splinter stack size to 99

Patch 3.2.4 Lifts Prime Evil Splinter Inventory Cap

Blizzard is raising the stack size for Prime Evil Splinters in Diablo 4 from 1 to 99 with the release of patch 3.2.4, build 74043, arriving across all platforms on October 28, 2026, ghacks.net reported. The upcoming update removes the strict one-per-type limit that has governed these seasonal power-granting items since the launch of Season 15 a few weeks ago.

Until now, players could carry only a single Prime Evil Splinter of any given type at a time. This restriction forced endgame players to rely on a demanding cooperative workaround requiring a second player to bypass the inventory ceiling. Stacks reaching up to 99 will render that workaround entirely obsolete.

Diablo 4 Players React to Stack Size Increase

The patch notes frame the adjustment as a standard stack size increase rather than an explicit bug fix, arriving on the heels of weeks of complaints from the Diablo 4 community. Reaction on the game’s official subreddit remains mixed. Highly upvoted commentary argues that the inventory change arrives far too late in Season 15 for players who have already stepped away from the game.

Players will not need to alter their inventory management manually to benefit from the adjustment. Once patch 3.2.4 is installed on October 28, collected Splinters of identical types will stack automatically up to the new cap of 99. The patch notes list no specific alterations beyond these inventory updates alongside general stability, visual, and user interface improvements.

Public Test Realm Previews Season 16 Systems

Alongside the live patch, Blizzard is opening the public test realm for update 3.3.0 from October 27 to November 3, offering an early look at upcoming Season 16 mechanics. Developer notes indicate that select features from the Season of Hell’s Legacy will carry forward into Season 16, though those specific features will remain absent from the public test realm as developers prioritize testing new additions.

The test build also introduces a Druid rework that strips Nature Shift and Shapeshifting tags away from individual skill upgrades, tying them directly to base abilities instead. These broader Druid adjustments aim to reduce tag stacking while increasing the combat weight of Resolve and Fortify builds. Blizzard notes that the new Tactics system is designed to let players tailor their War Plans more closely to specific goals and playstyles.
