Malignant Hearts are required for both powerful new builds and to complete Season Objectives to get rewards during the Season of Malignant.

How to get Malignant Hearts in Diablo 4

To get Malignant Hearts in Diablo 4, you have to kill special Malignant Monsters or craft them at Cormond's Wagon.

Before you can acquire Malignant Hearts, you have to kill partly corrupted monsters. You'll get a heart for doing so, but when you use the Cage of Binding to perform a ritual on the partly corrupted monsters, they return as fully corrupted monsters. Then, when you kill that fully corrupted Malignant Monster, you'll get a socketable Malignant Heart.

You get the Cage of Binding and learn how to do this ritual during the 'Burning from Within ' questline picked up at Kyovashad that introduces Cormond.

Keep in mind that there are actually four different types of Malignant Hearts that each offer a different category of power:

Vicious Heart (Offensive power) - Dropped from Vicious Malignant Monsters.Brutal Heart (Defensive power) - Dropped from Brutal Malignant Monsters.Devious Heart (Utility power) - Dropped from Devious Malignant Monsters.Wrathful Heart (Wrathful power) - Dropped from Wrathful Malignant Monsters.

You can only socket a Malignant Heart in the same colour of Infested socket - except Wrafthful hearts which can be placed in any Infested socket.

Malignant Hearts can also be crafted at Cormond's Wagon by salvaging unwanted hearts for Ichor of a corresponding colour. Salvaging each Vicious, Brutal, and Devious Heart will provide you with 5-15 Ichor, with Wrathful Hearts providing 2-5 Ichor of all other Heart types.

Creating a random Heart of a specific type costs 35 Ichor of the other two primary-coloured Hearts. For example, if you wanted to craft a Vicious heart, you would need 35 Brutal Ichor and 35 Devious Ichor. You would then receive a random Vicious heart that scales to the Level of your character. Don't worry, as the heart you create will always either be for your specific class, or can be used by all classes.

Vicious is the weakest type of Malignant Heart, then you improve with Brutal, then Devious, and finally Wrathful is the strongest type of Malignant Heart in Diablo 4. Although, each have their upsides for creating unique builds. Remember that the stronger the heart, the stronger the enemy you have to defeat it for is.

Additionally, Malignant Hearts always grant armor that directly maps with their item power.

The best place to get Malignant Hearts is by looking for the Malignant Tunnels, a new type of replayable dungeon. These tunnels contain lots of Malignant Creatures, including Varshan the Consumed, a new Boss.

At the end of these Malignant Tunnel dungeons, you need to use Malignant Invokers, a special Item crafted at Cormond's Wagon, to interact with Outgrowths of the same type, causing them to summon a fully corrupted monster. When defeated, you'll then receive a Malignant Heart that matches the monster's type.
