Learn how to find every keystone in Fisch Roblox including Turtle, Lightning, Sun, Skull, Fossil, and more.

Do you want to explore the new hidden locations? The Luminescent Caverns is a new location added in Fisch, but you first need to unlock it, and to do so, you need a few keystones. While the progress is simple and each player only needs three assigned keystones, knowing the locations of all nine helps you prepare faster. From caves and volcanoes to hidden structures and icy mountains, each keystone has a unique spot you’ll need to track down.
In this guide, we have listed the location of every keystone, including tips to collect them faster.
