Players who reach World Tier 3 in Diablo 4 will unlock Nightmare Dungeons, challenging maps that offer opportunities to farm XP. However, not all Nightmare Dungeons are equally effective for leveling up quickly. This guide aims to highlight the best Nightmare Dungeons in Diablo 4 for XP farming, advising players to prioritize clearing them whenever they obtain a related Nightmare Sigil.
It's worth noting that players seeking to maximize their XP farming should focus on Nightmare Dungeons with a Tier equivalent to their character level minus 50. For instance, if a player is Level 70, they should aim to clear Nightmare Dungeons around Tier 20. This approach ensures that the enemies inside the dungeon are three levels higher than the player character, resulting in a 25% increase in XP rewards compared to fighting enemies at the character's level.
There are five Nightmare Dungeons in Diablo 4 that are considered excellent for XP farming due to their high mob density and minimal backtracking. These dungeons, namely Aldurwood, Blind Burrows, Champion's Demise, Guulrahn Canals, and Raethwind Wilds, offer the advantage of being located close to their respective Waypoints, reducing the time players need to spend traveling to them.
Below the five Nightmare Dungeons lie the Abandoned Mineworks, Crusader's Cathedral, Earthen Wound, and Witchwater. These dungeons can all be considered A-Tier. While they may not be quite as good as the dungeons in the previous group, they still serve as excellent options for XP farming. Players should feel satisfied whenever they acquire their associated Nightmare Sigils in Diablo 4.
Players in the B-Tier will encounter Nightmare Dungeons such as Cultist's Refuge, Demon's Wake, Kor Dragan Barracks, Maulwood, Onyx Hold, Renegade's Retreat, Serpent's Lair, Sunken Ruins, Whispering Pines, and Zenith. At this stage, players should consider salvaging Sigils with challenging affixes for their builds, although it is generally recommended to clear these Nightmare Dungeons.
On the other hand, Ancient's Lament, Black Asylum, Conclave, Dark Ravine, Feral's Den, Guulrahn Slums, Lost Archives, Maugan's Works, Prison of Caldeum, Shadowed Plunge, and Shivta Ruins are best avoided by Diablo 4 players who are focused on farming XP. These dungeons, which could be categorized as C-, D-, and F-Tier, offer less value compared to other superior options available.
Diablo 4 is available for PC, PS4, PS5, Xbox One, and Xbox Series X/S.
