If you plan on fighting Vaal Shan in Diablo 4, you'll need to collect Vicious Hearts. This guide will help you find these essentials and explain how to use them for summoning. For those looking to speed up your progress, consider purchasing Diablo 4 Gold from RPGStash.com to make the process smoother.

Where to Find Malignant Hearts in Diablo 4

Vicious Hearts can be obtained by opening Whispering Caches and defeating Grotesque Debtors. These summoning items in Vaal Shan are tied to Grim Favors. Whether you get them from caches or they drop from Debtors, the process starts with completing Favors on the map. Each time you complete all 10 Grim Favors, a Debtor may spawn, allowing you to return to the Whispering Tree.

One effective strategy is to farm Hell Tides or defeat World Bosses. Not only will satisfying 10 Grim Favors spawn Grotesque Debtors, you can also see these enemies appear to other players. Grim Favors are plentiful in the Helltide region, increasing your chances of finding Malignant Hearts as a side reward.

World Bosses also offer the chance to drop summoning items. Each World Boss grants five Grim Favors, so it's common for Debtors to appear in droves. However, these methods can also yield Varshan's other three summoning items, making the process of obtaining a Heart somewhat tedious.

Unlike the other items, Malignant Hearts cannot be transferred at the Alchemist. So keep grinding for Favors and hope for a suitable drop on the next Varshan summoning.

To make grinding more efficient, you can Buy Diablo 4 Gold from RPGStash.com and ensure you have the best gear and resources for the fight.
