Diablo 4 Season of the Malignant Guide

Complete Guide to the new content introduced in Diablo 4's Season 1

Season of the Malignant Guide

Welcome to the Season of the Malignant, an extraordinary chapter in the realm of Sanctuary that promises an exhilarating journey through darkness, intrigue, and enigmatic challenges.

The core mechanic of the first Diablo 4 Season is the Malignant Hearts. This guide shall teach you all that is to be known about the Malevolent Hearts - where to obtain them, their purpose, and the ways in which you can harness their power to vanquish the encroaching darkness plaguing the Sanctum. 



The Malignant Hearts is essentially a substitute for Legendary Gems. You can Socket them inside your Jewelry as long as you have special Infested Sockets there, meaning you can have up to 3 Malignant powers active at once. To obtain Malignant Hearts, you will have to fight Malignant Monsters. Those are more powerful versions of regular Elites, you can find them everywhere through your journey in the Sanctuary. You can also face the challenge of Malignant Tunnels, six special Dungeons filled with Malignant Elites to the brim. There are 4 main Types of Hearts: Vicious Hearts (red) enhance offensive powers, Brutal Hearts (blue) bolster defensive abilities, Devious Hearts (pink) empower utility skills, and Wrathful Hearts (black) contain unspecific superpowers.


Obtaining Malignant Hearts

Randomly encountered Monsters have a chance to be Malignant, which makes them more powerful, and causes them to drop Caged Hearts, with random Type and Level. You should pick up every single of them, even if their power is useless for your character, as you can Salvage them for Ichors.  
The first thing you will have to do is to finish the new Questline commissioned by Cormond. Doing so will unlock the Crafting system related to the Hearts. There you will be able to craft Caged Hearts, Malignant Inovkers, and Uncertain Caches. Here is what they do: 

  • Caged Hearts: Grant a random Heart of a specific Type. 
  • Uncertain Caches: Grants a random Heart, of a random Type, one which can be of Wrathful Type.
  • Malignant Inovkers: used in Malignant Tunnels to summon powerful Elites, which will reward you with equally powerful Heart of the same type. 

You can eventually obtain your desired Heart by simply playing the game, but targeting specific types will make the hunt much faster and more efficient! 

Malignant Heart Effects

There is a total of 32 available Hearts, but some of them are Class-specific. Here you can find a list of each of them. The numeric values will depend on their Level, Item Power, and luck. You can use only one copy of each Heart at once.

Socketing Malignant Hearts

The new Season introduced new Socket Types. During the Season, Items will naturally drop with a randomly chosen type of Infested Socket. You can also add them via Jeweler. To insert Heart into a piece of Gear, you will need to match the Socket to the Heart type. The only exception to that are the Wrathful Hearts, which will fit any Socket type, as long as it is Infested. The important catch here is that you can't remove Heart from its Socket. You can only overwrite them with a different Heart, so you shall have a healthy amount of backup Hearts at your disposal. 


Malignant Tunnels

The Maginant Tunnels are a special type of Dungeons, available only to the ones participating in the Seasonal Realm. Here you can face many Malignant Enemies in high density, and it is obviously the best source of Malignant Hearts. At the end of the Tunnel, you will face the corrupted Boss, the Varshan the Consumed. You will also find there two Malignant Outgrowths, interacting with them will give you the chance to use the previously mentioned Invokers. Doing so will summon a powerful Elite enemy, which will drop a specific Type of Heart.
