Diablo 4 Malignant Hearts

With Season of the Malignant being released, we get to play the game in a completely new way. Season 1 introduces Malignant Hearts which are items that act like gems, and can be socketed into your Jewelry items.

In this guide, we will cover how you can get and use Malignant Hearts, and how many Hearts Season 1 offers.

How to get Malignant Hearts in Diablo 4

Malignant Hearts are the main theme of the first Season. There are four types of Hearts, and they are Vicious, Brutal, Devious, and Wrathful.

Heart Color Type Effect
Malignant Heart - Vicious Orange Vicious Offensive Effects
Malignant Heart - Brutal Blue Brutal Defensive Effects
Malignant Heart - Devious Pink Devious Utility Effects
Malignant Heart - Wrathful Grey Wrathful Powerful Effects

To get Malignant Hearts, you have to complete or skip the campaign, then either collect them through Crafting, defeating Malignant Monsters, or invoking Outgrowths.


How to Craft Malignant Hearts

After completing the first few parts of the Season quest, you will get introduced to Cormond’s Workbench. You will use this workbench to craft and salvage Caged Malignant Hearts.

To craft Caged Malignant Hearts, you need to use a material called Malignant Ichor which can be obtained by salvaging Hearts at Cormond’s Workbench or picking them up from lesser Malignant Monsters.

There are four types of Ichor that match the types of Hearts, and the type of Ichor you get depends on the type of Heart you salvage.

  • Salvaging Devious, Vicious, or Brutal Caged Malignant Hearts: 5-15 Ichor of that type
  • Salvaging Wrathful Caged Malignant Hearts: 2-5 Ichor of all types randomly.

Malignant Ichors

To view how many Malignant Ichors you have, simply access your character menu, navigate to the Materials and Resources tab, and scroll all the way down to see the accumulated Ichors.

Malignant Monsters

Early on in the Seasonal quest of Season 1, Cormond will give you an item called Cage of Binding, and this can be used to cage the hearts of Malignant Monsters. Those monsters are usually Elites that you can find anywhere within Sanctuary. However, the best way to farm Malignant Monsters is by running Malignant Tunnels.

Upon defeating the Malignant Monster, a Malignant Heart of a random type will drop which you have to interact with. Once you do, a stronger version of this Elite will summon along with some other monsters. Defeating the second Elite will drop the Caged Malignant Heart that can then be equipped into your Jewelry.



An Outgrowth is something that shows up at the end of a Malignant Tunnel, and from there you can use a Malignant Invoker to bring out the Malignant Monster that is bound inside the Outgrowth. Once you defeat the Malignant monster, you will get a Caged Malignant Heart.

Note that an Outgrowth can be of any of the four types as the Malignant Hearts, and to open them, you will need an Invoker of a similar type. Brutal, Devious, and Vicious Invokers can be crafted at Cormond’s Workbench.

How to use Malignant Hearts in Diablo 4

How to use Malignant Hearts

In Season 1, any Jewelry that drops will have a colored socket assigned to it randomly. The color of the socket can be either orange, pink, or blue similar to the types of Malignant Hearts. You can use a Malignant Heart by adding it to the Jewelry that has a socket color similar to the Heart. The only exception would be the Wrathful Heart which can be socketed into any color.

Keep note that once you use a Malignant Heart, you can never unsocket it from a Jewelry item. However, you can replace it with another Heart. You can also still add gems to your Jewelry if you’d like.

Diablo 4 Malignant Hearts List

For Season 1, there are 32 Malignant Hearts that can be collected and offer entirely different build-changing effects. These Hearts are split between shared Hearts that all classes can use and class-specific Hearts.

The following stats that I am using are taken from a level 20 character, and these stats change as your level increases. Also, some Malignant Hearts can be obtained from specific World Tiers.
