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

Release Date and Core Theme

Diablo 4 Season 10, Infernal Chaos, launches on September 23, 2025, at 10 AM PDT, immediately following the conclusion of Season 9, Sins of the Horadrim. This season introduces a chaotic twist to Sanctuary, with new mechanics designed to enhance build diversity and endgame activities. Expect a shorter season, running through December 2025, as Blizzard prepares for a major expansion in 2026.

Chaos Powers and Chaos Perks

At the heart of Season 10 are Chaos Powers and Chaos Perks, which act as the season's signature mechanics. Chaos Perks, available in Magic, Rare, Legendary, and Unique rarities, enhance your skills with additional effects. Each class gets 16 perks, including four class-specific ones, allowing you to equip one Unique and three non-Unique perks. These perks interact directly with your skills, legendaries, and paragon boards, offering fresh ways to customize your build. However, Chaos Powers are temporary, exclusive to Season 10, and won't carry over to the Eternal Realm.

Chaos Armor: Redefining Builds

Chaos Armor is a game-changer, allowing you to equip unique items in non-traditional inventory slots. For example, you could use the Crown of Lucion's damage-stacking effect alongside the Harlequin Crest in a different slot, unlocking previously impossible build combinations. This system, farmable through Infernal Hordes, encourages experimentation and could redefine the meta.

Revamped Infernal Hordes and Chaos Rifts

The Infernal Hordes mode gets a fiery overhaul, with tougher enemies, new chaos monsters that drop shrine-style buffs, and a Council Speaker mechanic that enhances the Fell Council's abilities. Additionally, Chaos Rifts introduce a new endgame activity, offering dynamic challenges and rewards. These updates make endgame farming more engaging, with increased baseline chances for unique items across various content.

New Boss: Bartuc, Warlord of Chaos

Season 10 introduces Bartuc, Warlord of Chaos, as the new seasonal boss. Expect a challenging fight that ties into the chaos theme, with unique loot drops that complement the season's mechanics. Bartuc's arrival adds another layer of excitement for players tackling endgame content.

Quality-of-Life Improvements

Blizzard is addressing community feedback with several quality-of-life updates:

• Loot Filter Progress: After initially resisting a loot filter, Blizzard now acknowledges the need for one due to the limitations of their current itemization fixes. While not confirmed for Season 10, discussions are underway, potentially leading to auto-salvaging of magic and rare items in Torment Tiers via your pet.

• Boss Loot Differentiation: Unique loot tables for bosses like Duriel, Andariel, and the Harbinger will be adjusted into a Venn diagram structure, making farming more rewarding and varied.

• Whisper Indicators: Active Whispers will now have visual cues, like a Nightmare Sigil catching fire, to guide players to specific content. This feature aims to streamline navigation and enhance the seasonal experience.

Season 10 PTR: Testing the Chaos

The Season 10 PTR ran from August 19 to August 26, 2025, allowing players to test Chaos Powers, Chaos Armor, and the revamped Infernal Hordes. Feedback from the PTR has shaped balance changes, with Blizzard focusing on eliminating bugs and refining these systems. Notable changes include doubled Dust Devil damage for Barbarians and tweaks to skill interactions, ensuring a smoother launch.

Looking Ahead: Season 11 PTR and System Changes

Blizzard has confirmed “fairly large system changes" for Season 11's PTR, expected to launch in late November or early December 2025. Community feedback highlights masterworking and tempering as key areas needing improvement, alongside potential updates to the Paragon system and endgame activities. These changes aim to address player concerns about repetitive seasonal mechanics and enhance long-term engagement. A revamped developer stream format will also debut with Season 10's launch, promising shorter, more focused updates to keep players informed.

Speculation: Paladin Class and 2026 Expansion

Rumors are swirling about a potential Paladin class, sparked by a datamined build labeled “2.5.Xpaladin.67961" on Blizzard's servers. While unconfirmed, this has fueled excitement for a holy-themed class with auras, possibly tied to a 2026 expansion set in Westmarch. Blizzard may drop hints at Gamescom (August 20-24, 2025), so keep an eye on their Twitch or YouTube channels for updates.
