Welcome to the Nightmare Dungeon Solo XP Tier List. These are the best Nightmare Dungeons to level your character up as fast as possible. The ranking is based on how much XP per hour you can gain when running dungeons with monsters of at least your own character's level or slightly above. Note: Some dungeons can be farmed more efficiently in groups, which is not reflected in the ranking.
The arrows indicate where an item has moved since our last Tier List update.
Dungeons are listed alphabetically within tiers.
