Theme and ruleset
Chaos Armor and Chaos Perks changed build possibilities. Chaos Rifts and refreshed Infernal Hordes shaped activities; Bartuc arrived as a new boss.
Start by the German calendar: 2025-09-23. Version family: 2.4. This season has ended; its original theme is not automatically active in the live game.
How progression worked in this season
Historical sequence for the period’s ruleset. These steps do not reactivate expired seasonal quests or theme powers in the current game.
Investigate Chaos
Begin Sands of Chaos with the distraught villager in Ked Bardu. Close Chaos Rifts in Helltides and Nightmare Dungeons for reputation and Infernal Warp.
Choose Bartuc deliberately
Infernal Warp upgrades Chaos Perks. Unique Perks come from Bartuc on Torment. Selecting Bartuc costs Aether and affects the party; agree before the final Hordes choice.
Reading builds correctly
An unusually placed unique effect could change several equipment constraints in this season. When reconstructing a build, check every slot and its origin. Do not carry Chaos Armor into a current equipment list without checking availability.
Compare wave clearing and single-target performance. Start with your class’s selected attack and examine whether the Chaos effect improves its conditions or merely produces a large number in a special situation.
Choose your class. Profiles state their historical version and full-setup requirements.
Diablo IV S10: Lunging Strike: two active Basic Skills
Hooves of the Mountain God and Paingorger support Lunging Strike, while Dual Threat uses the second equipped Basic Skill, Frenzy. Chaos Armor moves several normally weapon-bound Uniques into armor slots. Only two occupied bar slots are intentional in this specific version.
View buildDiablo IV S10: Blackwing Ravens in Grizzly Rage
Kilt of Blackwing and Stormcrow amplify Ravens. Savagery additionally turns Companions into Core Skills; the selected Grizzly version adds Rampaging Werebeast plus Poison and critical synergies. This is the complete 71-point setup, not the separately offered Human version with a different Ultimate.
View buildDiablo IV S10: Shadowblight with repeatable Soulrift
Alter the Balance turns Soulrift into a resource-spending Core Skill without its ordinary Ultimate cooldown. Repeated Shadow hits trigger Shadowblight, amplified through Blighted and Decay. Chaos versions of Ebonpiercer, Fists of Fate and Lidless Wall therefore occupy unusual armor slots.
View buildDiablo IV S10: Poison Dance of Knives with Chaos Armor
Dance of Knives carries the Poison package from Poison Imbuement, Bursting Venoms, Contamination and Star Shards. Chaos versions of Scoundrel’s Leathers and Fists of Fate are part of this Ubers setup. Hit and Run rewards continuous movement.
View buildDiablo IV S10: Hydra Ball with Mana Shield
Fireball supplies continuous attacks, while Hydra adds Conjuration damage and seasonal effects. Mana Shield moves protection onto Mana, giving Intelligence, maximum Mana and recovery a different role from an ordinary Life build. Ophidian Iris is worn as a Chaos chest here.
View buildDiablo IV S10: QuillMetheus: higher Pit tiers
Chaos Armor allows Rod of Kepeleke, Wushe Nak Pa and Sepazontec together in armor slots. The weapon can therefore carry Redirected Force, while Adaptability and the resource loop amplify Quill Volley. This is explicitly the demanding Pit version.
