It is worth noting that you can’t use just any keystone to open the Mysterious Crack. First, head to Sunstone Island and make your way to the Desolate Deep section, where you will see the crack and three pedestals. From here, you will learn which specific combination or set of keystones to get. Each Roblox player will get a unique combination, meaning you must follow the set to get into the Luminescent Cavern.

There are 9 keystones, but you will only need 3 to get into the cavern. Nevertheless, we listed down every single keystone location and its respective coordinates for your convenience.
