Comprehesive List of All the Legacy Zones and Boss Encounters in Diablo 4 Season 15

Diablo 4 Season 15 has brought in many legacy zones and boss encounters from previous Diablo games that players have come to love (or just have remembered). This includes areas from Diablo 1, 2, 3 and Immortal. Below is a list of all the legacy bosses added in Season 15, their drops and how to find them.

Note: This article is what we know so far, and will be continuously updated as more things are discovered.

These areas are known as Minor Nightmares, and can be found in several ways. Some of these dungeons are Capstone Dungeons, so they will be shown on the map at all times. Another way to encounter Waking Nightmares is in the open world, and the third way is with the use of Chronicles that behave similarily to Nightmare Dungeon keys.
