As Diablo IV continues to evolve, Blizzard keeps fans engaged with regular seasonal updates, typically arriving every two to three months. These seasons bring fresh mechanics, exclusive gear, new pets, and often a few surprises. With Season 9: Sins of the Horadrim wrapping up soon, players are already eyeing the next big chapter. Here's everything you need to know about the Diablo 4 Season 10 release date, its features, and how it fits into the game's 2025–2026 roadmap.

When Does Diablo 4 Season 10 Start?

Season 10: Infernal Chaos officially begins on Tuesday, September 23, 2025, immediately following the end of Season 9. This season will run through December 2025, acting as the final major season before Diablo 4's next expansion in 2026.

The launch date was first hinted at via the in-game Reliquary countdown, later confirmed in Blizzard's official roadmap for 2025. A 2.4.0 PTR (Public Test Realm) is also expected to arrive in August, giving players a sneak peek at the new content and features.

When Does Season 9 End?

Season 9 will conclude on September 23, 2025, the same day Season 10 launches. As with previous seasonal transitions:

· All Season 9 characters will migrate to the Eternal Realm.

· Their gear will be moved to a “Withdraw Only” stash tab, available for a limited time.

· To continue in Season 10, players must create new seasonal characters, as progress does not carry over.

What's New in Diablo 4 Season 10: Infernal Chaos?

Blizzard is packing a fiery punch with Season 10, offering meaningful changes for both new and returning players. Here's what to expect:

Chaos Powers (New Seasonal Mechanic)

Season 10 introduces Chaos Powers, a new layer of build customization. Much like the Horadric Powers from Season 9, Chaos Powers allow you to tweak and enhance your abilities, opening doors for more creative builds and unique playstyles.

Infernal Hordes Overhaul

The Infernal Hordes endgame activity is getting a significant update. Expect more chaos, new modifiers between waves, and deeper choices that enhance the farming experience for rare loot and materials.

Skill Tree Rework

While not fully confirmed for launch day, a major rework to the skill tree system is in the pipeline. This long-requested update will likely arrive during Season 10, aiming to make skill navigation and customization more intuitive and powerful.

New Season Journey & Blessings

A new Season Journey brings structured objectives and challenges for players, while Season Blessings return with new buffs and passive bonuses to guide your progress.

Reliquary Battle Pass Enhancements

Continuing with the Reliquary Battle Pass format, Season 10 offers multiple reward paths. Look out for:

· New Mounts

· New Pets

· Themed Armor Sets

· Unique Weapons

Unique Items & Legendary Aspects

Each of the six classes will potentially gain access to new Legendary Aspects and Unique Items, giving theorycrafters more tools to experiment with.

New Pet & Special IP Collaboration

Season 10 also introduces a brand-new pet, continuing the trend from earlier seasons. Even more exciting, Blizzard has teased another IP collaboration, similar to the Diablo x Berserk crossover, giving players even more cosmetic and lore-driven content.
