Blizzard maintains a relatively steady rhythm of releasing a Diablo IV season every 2 to 3 months,  to keep players engaged with fresh content. If you enjoy hunting for new gear and mastering challenging mechanics, this article covers the latest details on Diablo 4 Season 10, including its release date and exciting new features. We also highlight the end date for D4 Season 9, outline the full 2025 roadmap, and look ahead to the major expansion event planned for 2026.

Diablo 4 Season 10 Release Date - When Does D4 S10 Start?

Diablo IV Season 10, titled Infernal Chaos, is officially set to begin on September 23, 2025 (Tuesday). This season starts right after the end of Season 9 and will run through December 2025. Players can look forward to a fresh wave of content and seasonal challenges during this period. The announcement was confirmed via the in-game Reliquary countdown and later detailed in Blizzard’s 2025 roadmap. As the final season before the next big expansion in 2026, D4 S10 promises exciting new features and updates to keep the Sanctuary alive with action. And the Season 10 or 2.4.0 PTR is very likely to launch in August. 

Diablo 4 Season 9 End Date - When Does S9 of D4 End?

Diablo IV Season 9, known as Sins of the Horadrim, will conclude right before Season 10 begins, ending on September 23, 2025. As with every season transition, all characters created during S9 will be moved to the Eternal Realm. Your items earned for Season 9 characters will be transferred to a special Withdraw Only Stash tab in the Eternal Realm stash, so you must remember to retrieve your D4 gear before the stash becomes inaccessible at the end of season. Also, to participate in Season 10, you will need to create new characters as seasonal progress does not carry over.

New Features and Updates to Expect in D4 Season 10

• Chaos Powers: They would introduce a brand-new seasonal mechanic called Chaos Powers. These allow players to modify abilities, similar to previous power systems like Horadric Powers. This mechanic provides different ways to customize your character’s skills for the season and experiment with new builds.

• Infernal Hordes Update: The popular endgame activity, Infernal Hordes, will see significant updates to make it more chaotic and offer players more choices during gameplay. New advanced options between waves will give players more control and challenge in farming rare materials and gear.

• Skill Tree Rework: Blizzard has confirmed that a rework of the skill tree system is in development, potentially arriving during Season 10. This update aims to improve how players navigate and customize their skills, though the exact timing is still uncertain.

• New Season Journey and Blessings: D4 S10 will feature a new Season Journey and new Season Blessings, providing new quests and rewards to gain.

• Reliquary Battle Pass Updates: The Battle Pass system will continue with the Reliquary format, allowing players to focus on specific reward tracks. This season includes new mounts, pets, armor, and weapons to earn.

• New Unique Items and Legendary Aspects: Each of the six classes may receive new aspects and unique items.

• New Pet and IP Collaboration: Players can earn a new pet this season, continuing the tradition from previous seasons. Additionally, Season 10 will feature another exciting IP collaboration, similar to the previous Diablo 4 x Berserk event.
