Looting is a big part of Diablo IV, as you need to get as many useful items as possible. Most of the loot comes from defeating enemies, and you can also find chests all over the map.

How to Get Whispering Keys in Diablo IV
Unlike most other items in the game, Whispering Keys cannot be looted as normal loot. You cannot acquire them by killing monsters or opening chests. Instead, they can only be purchased from the Curiosities Vendor. To find out, you need to go to the bag icon on the map. The vendor has many items for sale, and you can buy the Whispering Keys from him for 20 obols each.

Obols are not difficult to find in Diablo IV, as they can be obtained by participating in special events. These events can be found on the map and are indicated by orange diamonds. All you have to do is complete the event to earn lots of Obols. Once you have enough, you can go to the vendor to buy the keys.

How to Use Whisper Keys in Diablo IV
As for their use, you will have to find silent chests. These silent chests can be found in different locations around the map. If you end up finding a Silent Chest but don’t have a Silent Key, we suggest using the Town Portal to quickly teleport to the nearest town and buying one from the vendor. Once done, use the key to unlock the chest. The best part is that silent chests will also reward you with gold in addition to items.
