Welcome to our Season 1 Malignant Hearts Guide for Diablo 4. We are fast approaching Diablo 4’s first ever Season launch. With each new season, new content in the forms of mechanics, themes, powers and more can appear in the world of Sanctuary. The theme for Season 1 is the arrival of a curse, spreading corruption in the form of Malignance across Sanctuary. However, with a new threat comes a new form of power to obtain!

Malignant Mechanics

In Season 1, any Elite enemy has a chance of being corrupted with Malignance. As a result of killing one of these enemies, you can capture and obtain Malignant Hearts. Malignant Hearts are the key to unlocking potential stronger end-game builds to fight off the new threat. To capture a Malignant Heart, players also require a Cage of Binding to perform a ritual in order to fully secure the Heart. It is easy to identify a Malignant Elite in Season 1 through an affix tag above their head.

How to obtain Malignant Hearts

With current information, the ritual that players can start to fully capture the Malignant Heart triggers an event. This event in particular also attracts all nearby Malignance to your location. Also included in this attraction of Malignance is a stronger version of the enemy you just defeated. As a result, be very careful once the Ritual has started as you can very easily find yourself in danger. Once all the enemies are killed, you receive the Caged Heart as a reward.

Malignant Tunnels

Malignant Tunnels are end-game locations only discoverable in Season 1. There seems to be only a limited amount of Tunnels available on the map, so make sure to locate them! At the end of each Tunnel, players can find an outgrowth. To fully interact with these outgrowths, players are required to break down older or less powerful Malignant Hearts for crafting materials. These crafting materials are then used to create Invokers. Using an Invoker on an outgrowth increases your chances of finding a specific type of Malignant Heart. The outgrowth itself has a color code that decides which color Heart drops. Receiving a Malignant Heart at the end of an Outgrowth does not require a Ritual to obtain it. Overall, the Malignant Tunnels and outgrowths provide players with a much easier farming option.

Malignant Heart Types

Malignant Hearts come with their own types and color codes. These color codes match Malignant Sockets on gear. For example, a blue colored Heart can only be slotted into a blue socket on gear. Each of these Malignant Heart Types also provide their own type of power.

Vicious Heart

Vicious Hearts are the offensive powers in Season 1. These Hearts also come color-coded Orange. There is a chance for them to drop from Vicious Malignant Monsters or also crafted via Cormand’s wagon. Certain pieces of gear in Season 1 can drop with Orange sockets called “Vicious Sockets” to slot these Hearts into.

Brutal Heart

Brutal Hearts are the defensive powers in Season 1. These Hearts also come color-coded Blue. There is a chance for them to drop from Brutal Malignant Monsters or also crafted via Cormand’s wagon. Certain pieces of gear in Season 1 can drop with Blue sockets called “Brutal Sockets” to slot these Hearts into.

Devious Heart

Devious Hearts are the utility powers in Season 1. These Hearts also come color-coded White. There is a chance for them to drop from Devious Malignant Monsters or also crafted via Cormand’s wagon. Certain pieces of gear in Season 1 can drop with Purple sockets called “Devious Sockets” to slot these Hearts into.

Wrathful Heart

Wrathful Hearts are the super powers in Season 1. These Hearts also come color-coded Purple. There is a chance for them to drop from Wrathful Malignant Monsters or also crafted via Cormand’s wagon. These Hearts seem set-up to be the most powerful of all Hearts. To further prove this idea, Wrathful Hearts can slot into ANY colored socket type.
