There are hundreds of Cellars, Dungeons, and Strongholds to test your might against in Diablo 4. With the introduction of Season 1, we are now given even more challenging areas. Dotted around the map, Blizzard has introduced Malignant Tunnels. These infested pits sit somewhere between a Cellar and a Dungeon and are filled with the Malignant enemies you will need for Season 1 of Diablo 4. There are 6 Malignant Tunnels so far in Diablo 4 Season One, and here is where you can find each one.
All Malignant Tunnel Locations in Diablo 4 Season 1
If you’re looking to farm Malignant Hearts and Ichor, the best idea is to run these Malignant Cellars. They can be done quickly and will reward you with some pretty great loot. Ichor is the main resource to collect in Season 1, so knowing the locations is pretty handy.
Hawezar Malignant Tunnel Locations
Hawezar is home to two of the Malignant Tunnels in Season 1 of Diablo 4. They are easy enough to locate on the map.
Den of the Blighted
Right in the middle of Hawezar, you will find the first Malignant Tunnel. It is located just to the northwest of the Ruins of Rakhat Keep. A quick one to reach.
The second Malignant Tunnel is located on the east side of the map by the Forsaken Coast. Use the Backwater waypoint to reach it quickly. Simply head there and travel Northwest.
Dry Steppes Malignant Tunnel Locations
Two more Malignant Tunnels are located in the Dry Steppes area of the Diablo 4 map. They can be found at the point marked in the images below.
Just south of Ken Bardu, you will find this Malignant Tunnel. It is conveniently close to Cormond’s Workbench. This makes it a great option for quickly scrapping Hearts for fast farming of Ichor.
Your best bet to get to this one quickly is to head north from Jirandai. It is slightly northeast of the spawn point in Diablo 4.
Fractured Peaks Malignant Tunnel Locations
Finally, Fractured Peaks plays host to the last two festering pits in Diablo 4 Season 1.
Fissure of malice
You can easily get to this one by heading to the Nostrava waypoint if you have cleared the Stronghold. Simply head south from there to access it. If you haven’t cleared the Stronghold yet, make your way to the Nevesk teleport point and make your way north.
The Boiling Wound
Lastly, we have The Boiling Wound Malignant Cellar in Diablo 4. You can find it east of the Malnok stronghold. If you haven’t completed the Malnok Stronghold yet, head south from Bear Tribe Refuge for an easy way into the final Malignant Tunnel in Season 1.
