Malignant Hearts are the star of Diablo 4 season 1, formally called Season of the Malignant. In season 1, you’ll be able to destroy Malignant enemies, capture their hearts, and place them into special jewelry sockets. Each Malignant Heart comes with its own Legendary-type effect, meaning you’ll be more powerful than ever once you have three Hearts equipped.

There are four different heart types in Diablo 4 season 1:

  • Vicious Hearts — Offensive, go in red jewelry sockets
  • Brutal Hearts — Defensive, go in blue jewelry sockets
  • Devious Hearts — Utility, go in purple jewelry sockets
  • Wrathful Hearts — Extremely powerful effects, can go in any of the three sockets

You’ll find these different colored Malignant Hearts while playing the game normally and fighting Elite enemies. Or — once you craft a special item — you can enter the new Malignant Tunnels and choose which color of Malignant Heart you’d like as a reward.

In this Diablo 4 guide, we’ve listed out all 32 Malignant Hearts and their respective effects so you can carefully plan your builds for the Barbarian, Druid, Sorcerer, Necromancer, or Rogue classes.
