Domhainne Tunnels new xp farm? by u/DaddyWithADumper in diablo4 Based on what several players have reported so far, the Domhainne Tunnels Diablo 4 dungeon is believed to be the best XP farm in the game. As posted on Reddit, an individual repeated this dungeon for around five hours with their Hardcore character and made their way to level 50 easily.If it took five hours for a hardcore character to reach level 50, there is a high chance it would take a regular character lesser time, considering the latter aren't required to be cautious. They can respawn after death, but hardcore characters cannot.

Once players hit level 50, the best way to farm for XP is by completing Nightmare Dungeons. These dungeons can be accessed in World Tier 3 and above. Comment by u/MadManNico from discussion Dopamine tunnel? in diablo4 Comment by u/BilboBagSwag from discussion Domhainne Tunnels new xp farm? in diablo4 While most players appreciate this dungeon, some deem the Domhainne Tunnels dungeon fairly overrated. To make matters worse, some believe this dungeon will be patched in an upcoming update because of the sheer amount of XP that players gain from continuously farming it. Comment by u/FIREFOX4374 from discussion Domhainne Tunnels new xp farm? in diablo4 It's unclear if the developers intentionally increased the number of mobs in the dungeon. If that's the case, then players won't have to worry about farming for XP over the next few weeks. Regardless, they should farm this dungeon as much as possible to level up quickly.
