From Blizzard Entertainment:
In Season 10, chaos consumes Sanctuary as the dreaded Bartuc, Lord of Chaos, emerges. Players will face reworked Infernal Hordes, battle through Chaos Rifts, and harness devastating Chaos Perks to carve their path through absolute madness.
- New Boss: The former Warlord of Blood, Bartuc, comes back to Sanctuary as the Lord of Chaos. This Vizjerai Warlord summons Chaos Portals to warp the battlefield.
- Wanderers can choose to challenge Bartuc during Infernal Hordes runs by earning enough Burning Aether. Those that defeat Bartuc grant the best rewards, including the most reliable source of Chaos Armor.
- Infernal Hordes Reignited: The endgame wave-based mode is reborn with Chaos Waves, escalating encounters that push even the strongest wanderers to their limits. While fighting The Fell Council, one member gets designated as Council Speaker with enhanced abilities.
- Chaos Perks & Chaos Armor: Seasonal reputation unlocks class-specific Chaos Perks that dramatically change builds. Chaos Armor adds a twist on Uniques, letting classic uniques roll at maximum power and allowing them to be equipped on non-traditional slots.
- Chaos Rifts: These unpredictable portals tear open across Helltides and Nightmare Dungeons, offering massive rewards once sealed. Players defeat new Chaos Monsters to grant seasonal reputation and Infernal Warps, a resource that upgrades Chaos Perks.
