One of Diablo 4‘s main endgame activities, Nightmare dungeons, will be permanently changed come Season 9, as Blizzard looks to make them both more challenging and surprising going forward.
As detailed in a new blog post, when Season 9 launches July 1, Nightmare dungeons will receive some major updates. Most notably, there will be a new activity within them called Horadric Strongrooms. Described as a “potent micro-dungeon,” strongrooms will be found more frequently on higher Torment difficulties and can also be reliably found by using a Nightmare dungeon sigil that guarantees the appearance of a strongroom.
Once players are inside the dungeon, players can discover a portal that will take them to the strongroom. In a system somewhat similar to Diablo 4’s Infernal Hordes activity, players will be able to select from a number of statues that add modifiers to the strongroom, increasing the challenge but also the rewards.
