With the Diablo 4 Season 1 launch, Blizzard has revealed what to expect from the new Malignant Hearts feature. These new Malignant Hearts are new powers players can socket into special items, which will be awarded once you finish the seasonal quest, and begin to collect hearts from Corrupted enemies and Malignant Tunnels. If you’re interested in finding out which ones you want to get for your build, here’s a Diablo 4 Malignant Hearts list, containing all hearts in Diablo 4 Season 1.

Here is a list of all 32 Diablo 4 Malignant Hearts, showing you what they are and what you need to do to get them. Image via Blizzard Entertainment.

In total, you will find 32 Diablo 4 Malignant Hearts on this list. These 32 Hearts are split into four groups of eight, with them all functioning slightly differently. The four groups are called Vicious, Brutal, Devious, and Wrathful. Vicious is your more offensive-themed Malignant Hearts, while Brutal are defensive powers, and Devious are utility themed. The last Malignant Heart theme is Wrathful, which are considered more ultimate themed gems, which are only seen on World Tier 4 or higher, making them the more big ticket hearts, if you will.
