What Are Malignant Hearts in Diablo 4?

Malignant Hearts are rewards for killing Malignant enemies in Diablo 4. They function similarly to Gems in that they can be slotted into gear to upgrade them.

Unlike Gems, Malignant Hearts can only be slotted into Malignant Sockets in Jewelry. They grant access to Malignant Heart Powers which are powerful unique abilities that upgrade as you level up.

There are four Malignant Heart types in Diablo 4:

  • Vicious Heart
    • Grants Offensive Powers and is slotted into Red Malignant Sockets
  • Brutal Heart
    • Grants Defensive Powers and is slotted into Blue Malignant Sockets
  • Devious Heart
    • Grants Utility Powers and is slotted into Purple Malignant Sockets
  • Wrathful Heart
    • Grants very powerful ‘Super’ Powers and can be slotted into any of the above three Malignant Sockets

How to Get Malignant Hearts in Diablo 4 Season 1

To get Malignant Hearts, you need to defeat Malignant enemies. You can then slot them into the corresponding Malignant Jewelry sockets of your choice.

Malignant Hearts can be upgraded into more powerful Caged Hearts. You need to defeat a partly corrupted Malignant enemy and capture them in a ritual using the Cage of Binding. You will receive the Cage of Binding as part of a questline in Diablo 4’s Season of the Malignant.

Once you have performed the ritual, it will transform the enemy into a fully corrupted Malignant enemy. Defeating it will give you a Caged Heart.

Fully corrupted enemy in Diablo 4 Season 1

These Malignant enemies are tougher than Diablo 4’s standard Elites and will spawn at random throughout the game.

A more reliable way of farming Malignant Hearts is to run through one of the six Malignant Tunnels introduced in Season 1. These are smaller versions of Diablo 4’s dungeons that are infested with Malignant enemies.
