These highly-farmable dungeon variants offer players the best way to get their hands on powerful Malignant Hearts—though you will need a Wrathful Malignant Invoker to get your hands on the very best.

In total, there are six Malignant Tunnels scattered across the Diablo 4 map, with two each in the Fractured Peaks, Dry Steppes, and Hawezar regions.

You can find all Malignant Tunnel locations below, along with tips on the best travel routes and a heads up on the Invokers you will need for each.

The Dindai Hollow can be found in the western area of Dindai Flats in the Dry Steppes region of Diablo 4.

Unfortunately, Dindai Hollow is the hardest Malignant Tunnel to access with no nearby waypoints. You can either head west from the Onyx Watchtower or southwest from Ked Bardu. But neither journey is quick.

The Outgrowth at the end of the Malignant Tunnel requires either a Brutal Malignant Invoker or a Wrathful Malignant Invoker.

Ravening Pit

For the quickest access to Ravening Pit, start your journey at Qara Yisu and exit from the west side. Then, travel slightly northwest.

For the Outgrowth at the end of the Malignant Tunnel, you will need either a Brutal Malignant Invoker or a Wrathful Malignant Invoker.
