In Diablo 4, players will need to carry with them a few Whispering Keys at all times in case they come across a Silent Chest in the wild.
When out in the dangerous world of Sanctuary, Diablo 4 players will most likely come across some Silent Chests. These chests can be found just about anywhere, and they can be filled with some very good items. However, they are locked, and they can only be unlocked with an item called Whispering Keys. These keys can only be purchased from one vendor in the cities of Sanctuary, and players will want to find these vendors as quickly as possible to keep from missing out on the loot inside each Silent Chest.
There is only one type of vendor that sells Whispering Keys in Diablo 4: Purveyor of Curiosities vendors.
