How To Find The Bell Tower Key – Dead Cells

Turn up the volume and ring my bell

In the Clock Tower level in Dead Cells, there’s a mysterious door that requires the Bell Tower Key to unlock, guarding a blueprint for a fancy looking shield (the Punishment shield, which reflects all damage on nearby enemies and does critical damage if parry is successful).

You may have also noticed four seemingly useless bells throughout the Clock Tower that you can interact with (pictured below). When you melee or shoot each of the four bells, they resonate with a different tone, ranging from lowest to highest in tone.

To unlock the Bell Tower Key, you need to hit the four bells in order of lowest pitch to highest pitch! The map below shows how far apart the bells were on the run when I got the Bell Tower Key. When you hit the fourth bell, the key will suddenly appear and drop to the ground.
