Diablo 4 Season 1 is upon us, and that means you're probably out there hunting for a powerful new class modifier. Diablo 4 Malignant Hearts are a new type of socketed item introduced as part of Season of the Malignant, and they contain the power to unlock destructive new builds as you level through the Season Journey in Diablo 4

Here I'm going to explain what the caged hearts are and where you can find them. I'm also going to walk you through the full Diablo 4 Malignant Hearts list, and cover all of the powers and bonuses that the new collectible items can unlock. There's a lot to wrap your head around, but remember, before you can enjoy any of this you'll need to learn how to create a seasonal character in Diablo 4 and complete chapter 1 of the Season Journey in Diablo 4 Season 1.

How Diablo 4 Malignant Hearts work

Malignant Hearts in Diablo 4 are a brand new socketable item, introduced specifically for Season 1. You can equip three Caged Hearts at once, with one being placed in your Amulet and then in one of your two rings. 

Low-level caged hearts can be collected as you defeat Malignant Monsters spawning all across Sanctuary, while rare Malignant Hearts can be collected by making use of the new Diablo 4 Malignant Invoker item on Overgrowths that spawn at the end of Malignant Tunnel dungeons. Malignant Hearts come in four color variants, and there are 32 in total split across the classes – each can be slotted into jewelry that has an infested socket of the same color, and used to unlock powerful class buffs.

Note that you'll need a Diablo 4 Wrathful Invoker to get the more powerful Wrathful Hearts, and the Diablo 4 Invoker of Varshan to use on the seasonal boss once you've defeated them.

There are four different Malignant Heart types in Diablo 4. You'll need to match the color of the heart to the color of the socket on your jewelry for the transfusion to work – although there is one exception to this that I'll get to in a second. 

  • Vicious Hearts – Offensive Power, goes into red Jewelry sockets; drops from Vicious Malignant Monsters or crafted via Cormond's wagon. 
  • Brutal Hearts – Defensive Power, goes in blue Jewelry sockets; Drops from Brutal Malignant Monsters or can be crafted via Cormond's wagon. 
  • Devious Hearts – Utility Power, goes in purple Jewelry sockets; Drops from Devious Malignant Monsters or crafted via Cormond's wagon. 
  • Wrathful Heart – Super Power, this black heart can go in any of the three Jewelry sockets; Drops from Wrathful Malignant Monsters or crafted via Cormond's Wagon.

Where to get Malignant Hearts

You'll begin collecting Malignant Hearts as you begin completing the Diablo 4 Holding Back the Flood questline. This will introduce you to the concept of the caged hearts, teach you how to craft Invokers, and help you identify Malignant Tunnels on the Diablo 4 map – just look for the little green leaf, which signals Seasonal activities. 

You can find Malignant Hearts by killing Malignant enemies throughout the overworld, you can salvage old hearts and use the materials to craft new ones at Cormond's wagon, or you can head into the Malignant Tunnel dungeons. Complete one of these Seasonal dungeons and at the end you'll discover an Overgrowth – stab it with a specifically colored Invoker and it'll summon a powerful Malignant Elite who, once defeated, will drop more powerful Hearts of the same color-type. 

How to craft Malignant Hearts

You can craft new Malignant Hearts at Cormond's Wagon (located near waypoints, as indicated by a little green leaf icon) using a new resource called Ichor in Diablo 4 Season 1. You can get your hands on Ichor from Salvaged Malignant Hearts and from killing lesser Malignant Monsters. 

Salvaging one of the four types of Malignant Hearts (Vicious, Brutal, Devious, and Wrathful) will yield different Ichor types that correspond to that color-type. Vicious, Brutal, and Devious hearts will yield between 5-15 Ichor, depending on its rarity and level, while a Wrathful heart will return 2-5 Ichor of all other Heart type colors. 

So let's say you wanted to create a random Vicious Heart at Cormond's Wagon. That would cost you 70 Ichor of the other two colored hearts combined – so in this instance, 35 Brual Ichor and 35 Devious Ichor. The random heart that spawns will scale to your level, and always be usable by the class you are playing as. 

All Diablo 4 Malignant Hearts

There are 32 Malignant Hearts in Diablo 4 Season 1. There are four unique to each class (Barbarian, Druid, Necromancer, Rogue, Sorcerer) and a further 12 which can be used by all of the classes. Remember though, each of the Malignant Hearts can only be socketed in the correct color of Infested Socket – except for the powerful Wrathful Hearts, which can go in any socket color.

All of these Malignant Hearts, unless specified, can be used on any Diablo 4 World Tier in the Seasonal Realm.

What happens to Malignant Hearts when Season 1 ends?

When Season 1 of Diablo 4 ends in October, all of your Malignant Hearts will disappear. These special items will only be active during the Season of the Malignant so – so you'll need to make use of the power boost now to help move through the Diablo 4 battle pass ranks. Once Season 1 ends, your character will be transfered to the Eternal Realm and, once there, all your Infested Sockets will become regular sockets which will accept normal Diablo 4 gems.
