'''Malignant Hearts''' are new item that can be slotted into jewelry during [[Season 1]] of Diablo 4. 

Caged Hearts will function similarly to Legendary Gems, which can be inserted into only infested jewelry sockets of a matching color, and will grant the character new abilities leading to powerful and radically new builds for all classes. 

== How to get Malignant Hearts ==
In the Season of the Malignant [[Season 1]], players will slay partially corrupted Malignant monsters which will drop a Malignant Heart. 

* Any Elite enemy will have the potential to spawn as ''Partly Corrupted'', which will drop a Malignant Heart after being slayed.
* Players may then attempt to collect the Heart with the Cage of Binding ritual, which will spawn an even more powerful, ''Fully Corrupted'', version of that enemy.
* The player will be able to collect the Caged Heart after successfully defeating the Fully Corrupted enemy.<center><gallery mode="nolines">

</gallery></center>

== Malignant Hearts Colourings ==
There are '''32 Malignant Hearts''' that provide build-altering bonuses. The Hearts are broken into four categories, each with a corresponding color and unique keyword: Vicious (Orange, Offensive power), Brutal (Blue, Defensive power), Devious (Pink, Utility power), and Wrathful (Black, Super). Defeated Malignant Monsters will drop a Heart that corresponds to the monster’s color.
== How to use Malignant Hearts ==

* All jewelry may drop with any one of the three different color-coded infested sockets, including those items obtained from Tortured Gifts in Helltides as well as from gambling.
* Randomly colored Infested sockets may also be added to an item at the Jeweler. Caged Hearts will be destroyed if removed from a jewelry item.
* Players will be searching for jewelry items with sockets of a specific color depending on which Caged Heart they wish to use.
* The strength of the Hearts will increase as the player progresses through the Season. Unsocketed Hearts that are no longer wanted can be salvaged to produce a special resource, which can then be used to craft Invokers.
* Only one Wrathful Heart can be equipped at a time and are the most powerful Heart.
* Seek out Wrathful Hearts by running Malignant Tunnels or crafting a Wrathful Malignant Invoker to be useed at the end of a Malignant Tunnel.

== Crafting and Salvaging ==
As players encounter more powerful Malignant Creatures, so too will the strength of their Malignant Hearts grow. Any Heart that you don’t wish to keep can be '''salvaged at Cormond’s wagon for Ichor''' of a corresponding color. 

Ichor is a resource that allows for the creation and upgrade of Malignant Hearts and can also be harvested from lesser Malignant Monsters. 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-colored Hearts. For example, if you wanted to craft a Vicious heart, you would need 35 Brutal Ichor and 35 Devious Ichor. In return, you would receive a random Vicious heart that scales to the Level of your character. The random Heart you create will always either be for your specific Class or Class-agnostic.

* Brutal, Devious and Malicious Invokers can be crafted. Wrathful Invokers cannot be crafted and are contained and randomised in Uncertain Invoker chests which can be crafted with Malignant Ichors.
* It's worth noting that Cormond has a workbench in all major city locations so you do not need to go to his camp every time you want to craft.

== How to Farm Malignant Hearts ==

* Upon completion of the Seasonal Questline, players may enter Malignant Tunnels, which are new areas throughout Sanctuary with a higher chance for Malignant Elites to spawn and the most efficient method of farming Caged Hearts.
* Malignant Growths will spawn in a few different colors at the end of a Malignant Tunnel. Players will choose to interact with one of these Growths, depending on which color Heart they wish to obtain.
* Interacting with a Malignant Growth using a crafted Invoker (crafted at Cormond's camp) will spawn a Malignant enemy. In this situation, the player can obtain the Caged Heart immediately after slaying the enemy and will not need to perform the Cage of Binding ritual.

== Invoker of Valshan ==

* This can only be crafted with the Invoker of Valshan recipe which is acquired at the end of the Seasonal questline and dropped by the final boss.
* The invoker of Varshan spawns the Echo of Varshan.
* Defeating the Echo of Vatshan in World Tier 2 will provide loot and the Foul Invoker of Varashan and its recipe. This summons the Echo of Vatshan in World Tier 3 and World Tier 4.

== All Malignant Hearts ==

The stats on the listing below are based on a level 20 character when they drop. Players can acquire a Heart in any World Tier on the Seasonal Realm.
