Associate Game Director Joseph Piepiora has confirmed that Nightmare Dungeons in Diablo 4 have a higher chance to drop as Sacred or Ancestral! This official statement appears to incentivize players to give the Nightmare Dungeon system, which is supposed to serve as challenging end-game content, a shot. Currently, a lot of players prefer to farm experience in normal dungeons with favorable layouts like Champion's Demise or Blind Burrows rather than taking on challenging content like Nightmare Dungeons.

Additionally, Blizzard acknowledged the current situation in their latest Campfire Chat livestream and is planning to increase monster experience in Nightmare Dungeons and to decrease travel time to and between Nightmare Dungeons through dungeon teleports.

In the replies under his initial tweet, Piepiora stated that Uniques would also have a higher chance to drop as Sacred or Ancestral in Nightmare Dungeons - however, we can't confirm if this is the current status quo or an improvement coming with the aforementioned Nightmare Dungeon changes.

Also you can consider buy Diablo 4 boosting services to enhance your chances of obtaining these coveted Sacred and Ancestral Uniques. As players eagerly await further information, the prospect of improved loot drops has certainly piqued their interest.
