Whether you notice a gap in your bestiary or you’re stuck on the puzzle, you need to obtain the Fisch Radiant Crystal. We’ll explain where you can get it from and why you need it.
Start playing Fisch on Roblox. To get this crystal, you need to make your way inside The Mineshaft. It’s a brand new area to explore with puzzles, gems, and NPCs.
How To Get The Fisch Radiant Crystal
The only way to get the Radiant Crystal is by fishing in the Mineshaft. Who knew you could fish for crystals! Unlike the other creatures you can catch in Fisch, it has no preference for the weather, time, season, or bait you use. It all comes down to RNG luck.
Mineshaft Location
Our guide linked above goes into more detail on everything inside the Mineshaft and how to get to it. But in short, you need to unlock The Chasm first. You can do this by obtaining the Merlin’s Viel effect, which you get by giving Merlin all of the Shards. To get a Shard, you need to complete a Rift.
After handing him the Shards, speak to Merlin and choose the option that says you need to enter The Chasm. Enter The Chasm, and the game will teleport you to The Mineshaft.
Why Do You Need The Radiant Crystal?
Inside The Mineshaft is a puzzle, and you need the Radiant Crystal if you want to complete that puzzle. There are three pedestals inside The Mineshaft, and you need to place the correct items on each pedestal.
One of the items, as you may have guessed, is the Radiant Crystal. You also need a Rough Geode, which you get from The Mineshaft by breaking the Rubbles using a Spear.
Lastly, you need The Cult Gem. You get this by pulling the lever in The Mineshaft at the right time, so the cart goes onto the other track.
