The Diablo 4 Public Test Realm (PTR) is returning soon to preview the new content and changes inbound for Season 10, including an Infernal Hordes revamp, a new boss, and a new unique armor type, Chaos Armor. The Season 10 PTR will be available from August 19 to August 26 for PC players.
Where Season 9 brought a revamp to Nightmare dungeons with Horadric Strongrooms and Escalating Nightmares, Infernal Hordes is next on the list for a refresh. The Season 10 PTR will introduce new Chaos Monsters that provide shrine-like buffs when defeated, as well as optional Chaos Waves that will dramatically up the difficulty of a wave in return for a higher Aether reward.
The Fell Council is also getting a rework–one member of the Council will be designated as Council Speaker each time you fight them, gaining enhanced abilities along with the title promotion. Players will also have the option of ignoring the Fell Council altogether and opting into a brand-new boss fight with Vizjerei Warlord Bartuc–formerly the Warlord of Blood, now the Warlord of Chaos. Players will have to spend Aether to fight Bartuc, but the punishing boss fight promises increased rewards if the party successfully defeats him.
