New patch notes for Season 10 of Diablo 4 have been released, introducing chaos armor and new perks, while addressing boss immunity phases. The update includes the removal of boss immunity, replacing it with a shield mechanic for endgame lair bosses. Players can now find a non-helmet variant of the Crown of Lucion, and additional items for each class have been added based on player feedback from the public test realm. Nightmare dungeon sigils will indicate their validity for active Whispers, and rewards from Chaos Rifts will be improved. Infernal Hordes have been revamped, with Soul Spires receiving bonuses and chaos waves spawning less frequently but yielding greater rewards. Class-specific chaos perks have been adjusted, with buffs for Rogues and slight nerfs for Druids. Season 10 is set to launch on September 23.
