Diablo 4 is here, and the world is dark and full of treasures to find. Not all treasure needs to be looted off the corpse of a hellspawn though, some can be found in treasure chests around the map.
Some chests aren't as easy to crack open though, and you've probably come across Silent Chests and been unable to pry them open. The game will prompt you to use a Whispering Key. Where does one acquire one of these mysterious items?
