This guide will let you know where to find Crystal Sulphide in No Man’s Sky. Go through the guide and follow the step-by-step instructions to find it.
To start, you will need to look around in your system and go to the planet with water. If the system you are in doesn’t have a planet with water on it, then you’ll have to warp to a different system until you reach one with a planet with water on it.
After that, you have to go into a large water source and swim around while looking for a sort of mini-volcano type formation, and on the sides of it, you’ll see crystals that you can pick up and will give you crystal sulphide. You can also see the crystal sulphide if you use your analysis visor underwater; they will appear with a small beacon.
