The centerpiece is Bartuc, formerly the Warlord of Blood, now returning as the Lord of Chaos. This Vizjerai warlord can summon Chaos Portals to warp the battlefield and drastically change the fight.
What Makes Infernal Chaos Revolutionary
At the end of Infernal Hordes runs, players face a choice: fight the Fell Council or challenge the insidious Bartuc. Defeating Bartuc grants the best rewards, including reliable Chaos Armor drops.
Chaos Rifts tear open across Helltides and Nightmare Dungeons, offering massive rewards once sealed. These unpredictable portals spawn new Chaos Monsters that grant seasonal reputation and Infernal Warps – a resource for upgrading Chaos Perks.
Chaos Armor revolutionizes the Unique system, allowing classic uniques to roll at maximum power and be equipped in non-traditional slots. This creates unprecedented build flexibility and power scaling.
Enhanced Infernal Hordes Experience
The endgame wave-based mode gets completely reworked with Chaos Waves – escalating encounters designed to push even veteran players to their limits. During Fell Council battles, one member becomes the Council Speaker with enhanced abilities, adding tactical depth.
Players must hunt down the five Fell Council members and defeat Bartuc, Lord of Chaos, creating a structured progression system within the chaos.
Seasonal Progression & Rewards
Chaos Perks unlock through seasonal reputation, offering class-specific abilities that dramatically transform builds. These aren’t minor tweaks – they’re game-changing mechanics that redefine how each class approaches combat and exploration.
The season introduces a compelling narrative about an order working to find the source of Chaos Rifts and what they unleash, adding story depth to the mechanical improvements.
