Season 10 of Diablo 4 delivers a bold shake-up to Sanctuary’s endgame. With the introduction of Infernal Hordes, Chaos perks, and a terrifying new boss, Bartok, players have more opportunities than ever to push their builds to new heights. This Diablo 4 Items for sale guide breaks down the major features and provides strategies to help you succeed in the chaos-filled battlegrounds.

Entering the Infernal Hordes
The Infernal Horde mode challenges players to face escalating waves of enemies in a relentless arena. At the center lies a boss who must be defeated before you can progress. Once the fight ends, you’re given impactful decisions, such as increasing monster health by 100% for extra rewards or spawning Ether events where Ether Goblins drop bonus Ether. These choices make every run unique and push you to balance risk against reward.
Etheric Events and Overhauled Mechanics
One of the standout changes in Season 10 is the rework of Ether interactions. Now, Etheric masses can spawn elite Ether Lords, Hellborne enemies can appear during regular encounters, and Ether Fiends have the chance to evolve into powerful Ether Lords. This unpredictability keeps battles fresh and ensures that no two Infernal Horde runs feel alike.
Chaos Waves: High-Risk, High-Reward Gameplay
Instead of selecting a simple boon, you can trigger a Chaos Wave—a mini-game within the Horde. During these waves, you’ll need to defeat Ether Fiends quickly while dodging hazardous effects scattered across the battlefield. Success can net you up to 200 Ether, making Chaos Waves one of the best ways to stockpile resources. However, a single mistake can cost you the rewards, so precision and mobility are key.
Facing Bartok, Season 10’s New Boss
After clearing 10 waves, players can choose to face the Fell Council or summon Bartok, the season’s fearsome boss. Summoning Bartok requires 666 Ether, and defeating him before he grows too powerful is critical. If you delay, Bartok can become invulnerable and unleash devastating attacks that wipe out unprepared parties. To succeed, focus on burst damage and well-timed abilities that keep him from reaching later phases.
The Power of Chaos Perks
The addition of Chaos perks is one of Season 10’s most exciting features. These perks dramatically change the way you build and play your character. For example, “Beast Cornered” provides a 100% damage boost when your health drops below half, while “Alter the Balance” transforms core skills into ultimate-level abilities. By stacking the right perks, you can unlock devastating synergies that push your damage output into unprecedented territory.
Chaos Gear and Customization
Season 10 also introduces Chaos gear, with unique items that roll maximum aspects and open up deeper customization paths. Players can gamble for Chaos uniques, tailoring their equipment to specific builds. This system not only makes hunting gear more rewarding but also ensures that players can fine-tune their loadouts for Infernal Hordes, Chaos Waves, or the Bartok fight.
Chaos Portals and Extra Rewards
While exploring Hell Tide zones, you may encounter Chaos Portals—events that offer valuable loot and resources. These portals grant Aberrant Cinders, bonus XP, and additional gear. They’re also a great way to stay ahead in power progression without relying solely on the Horde itself, making them a must-visit feature for those seeking maximum efficiency.
A Season of Experimentation
Season 10 stands out as one of the most experimental chapters in Diablo 4. Between the relentless Infernal Hordes, the gamble of Chaos Waves, the deadly fight against Bartok, and the limitless possibilities of Chaos perks, players have endless ways to unique item diablo 4 test new builds and strategies. The key to success is experimentation—embrace the unpredictability, refine your approach, and Sanctuary will reward you with power and loot beyond imagination.
