Blizzard Entertainment has officially announced Diablo IV Season 10 – Infernal Chaos, launching on 24 September 2025 (AEST / UTC+8). The update promises to plunge Sanctuary into deeper darkness, bringing new enemies, mechanics, and rewards that will push even the most seasoned wanderers to their limits.
With the return of the notorious Bartuc, Lord of Chaos, players can expect a brutal test of skill, strategy, and endurance. Infernal Hordes are reborn, Chaos Rifts open across the world, and a brand-new layer of Chaos Perks and Chaos Armor add fresh twists to character builds.
Season 10 is shaping up to be one of the most intense chapters yet in Diablo IV’s evolving journey.
Bartuc Returns as Lord of Chaos
At the heart of Infernal Chaos is the rise of Bartuc, the former Warlord of Blood. Once a deadly Vizjerai Warlord, Bartuc now embodies the title Lord of Chaos, summoning destructive Chaos Portals that warp battlefields into unpredictable arenas.
Players can encounter Bartuc during Infernal Hordes runs by collecting enough Burning Aether. Defeating him won’t be easy, but the rewards are worth the challenge.
Bartuc grants access to some of the best loot in the game, including the most reliable source of Chaos Armor. For those seeking high-risk, high-reward battles, Bartuc will quickly become the ultimate test of strength this season.
Infernal Hordes Reignited
The popular endgame wave-based mode, Infernal Hordes, has been overhauled with Chaos Waves. These escalating encounters crank up the intensity, pushing wanderers into battles where endurance and adaptability matter most.
Players will also face off against The Fell Council, where one council member takes on the role of Council Speaker—wielding enhanced abilities that dramatically raise the stakes. Each run offers increasingly chaotic combat, ensuring no two encounters ever feel the same.
Chaos Perks and Chaos Armor
Seasonal progression in Infernal Chaos introduces a new reputation system tied to unlocking Chaos Perks. These class-specific perks allow wanderers to experiment with entirely new builds, dramatically shifting playstyles.
Whether you’re a Sorcerer craving explosive power or a Barbarian seeking unbreakable resilience, Chaos Perks bring fresh customization to the battlefield.
Meanwhile, Chaos Armor redefines how unique items function. For the first time, classic uniques can roll at maximum power and be equipped in non-traditional slots, breaking conventional rules of itemization.
This flexibility opens up creative new ways to maximize damage, defense, and utility—perfect for players who love to craft unorthodox, yet devastating builds.
Chaos Rifts: Unpredictable Power
Adding even more excitement, Chaos Rifts will now randomly appear during Helltides and Nightmare Dungeons. These unpredictable portals tear open across Sanctuary, pulling wanderers into battles against new Chaos Monsters.
Successfully closing these rifts yields huge rewards, including Infernal Warps—a valuable resource for upgrading Chaos Perks. For players who thrive on unpredictability, Chaos Rifts provide high-intensity combat with the promise of legendary loot.
A Season of Madness Awaits
With Bartuc’s return, Chaos Perks shaking up builds, and a reimagined Infernal Hordes, Diablo IV Season 10: Infernal Chaos is set to deliver one of the most thrilling seasonal updates yet. Sanctuary is on the brink of destruction, and only the bravest wanderers will survive the chaos.
Whether you’re hunting for rare Chaos Armor, mastering new class perks, or battling through the relentless waves of Infernal Hordes, this season offers endless opportunities to test your skills. Prepare to embrace the madness, as Infernal Chaos consumes everything in its path.
