Season 10 — Infernal Chaos

Unique-defined identity. Historical archive.

Season 10 — Infernal Chaos — pivoted the meta away from stacking Legendary Aspects toward build identity defined by Unique Perks and Chaos Armor. Bartuc, Warlord of Chaos joined Infernal Hordes as an alternative boss. The season was widely praised for its build-crafting flexibility.

Seasonal Mechanic — Chaos Perks

16 Chaos Perks per class across four rarities: Magic, Rare, Legendary, Unique. Unique Perks reshaped build identity — some were build-defining. Chaos Rifts in Helltides + NMDs awarded Infernal Warps to upgrade Perks.

Chaos Armor

Enhanced uniques occupying non-traditional slots, enabling cross-slot synergies. Always rolled at maximum item power with at least 1 Greater Affix. This made Chaos Armor the most reliably powerful drop source of the season.

Bartuc, Warlord of Chaos

Alternative boss for Infernal Hordes end-encounters, unlocked by banking 666+ Burning Aether before the final chest. New Chaos Monster family granted shrine-like buffs on death, rewarding aggressive farming.

Top Meta Builds

  • Ice Hydra Sorcerer (top-tier)
