How To Get Cave Sulfur In Subnautica

Okay, picture this: you're chilling on a beautiful (if slightly terrifying) alien ocean world, right? Everything's peachy… until you realize your trusty Seamoth is about as durable as a wet paper bag in a hurricane. You need to upgrade, my friend, and that's where the glorious, slightly smelly, wonder that is Cave Sulfur comes in.
Think of Cave Sulfur like the duct tape of Planet 4546B. It's not glamorous, it doesn't sparkle, but it’s absolutely essential for making your vehicles tougher and your weapons, well, more explode-y. You wouldn't try building a house without nails, would you? Same principle here!
Why All the Fuss About Cave Sulfur?
Simply put, Cave Sulfur is a key ingredient for crafting Reinforced Dive Suits and, more importantly, Torpedoes. Let's break that down:
Must Read
- Reinforced Dive Suits: Those pesky biters and crashfish? They'll be a lot less bite-y and crash-y when you're wearing armor plated with the power of sulfur. Imagine wearing a suit made of tiny airbags – except the airbags are made of, you know, rock.
- Torpedoes: Need to deal with a Reaper Leviathan eyeing your brand-new Seamoth like it’s a seafood platter? Torpedoes are your best friend. They're like the ultimate "go away!" button for oversized sea monsters. And trust me, you'll need it.
Without Cave Sulfur, you’re basically stuck with tickling leviathans. And nobody wants that.
So, Where Do We Find This Stinky Gold?
Alright, let's get down to business. Finding Cave Sulfur isn’t like stumbling across a shiny pearl on the seafloor. It requires a little bit of exploration, a dash of bravery (or maybe just a slight disregard for your own safety), and a good pair of eyes.

The best place to hunt for Cave Sulfur is within Crashfish Caves. These caves are usually near the Safe Shallows, Kelp Forest, or Grassy Plateaus. Think of them as sulfur-filled treasure chests guarded by… well, grumpy little explosive fish.
Here's the catch: Crashfish love their homes. And they really don't appreciate visitors. When you get too close to a Cave Sulfur deposit, a Crashfish will emerge, launch itself at you like a furry, finned missile, and… BOOM! Not a pleasant experience, trust me.

Crashfish Cave Diving 101: How to Snag That Sulfur
Okay, we know the location, we know the threat. Now, let’s talk tactics. Getting Cave Sulfur safely involves a little finesse and a whole lot of strategic maneuvering.
Here’s a step-by-step guide to sulfur-snatching success:

- Gear Up: Fins, O2 tank, and a Seaglide are your friends. The Seaglide will help you outrun the crashfish. A repair tool is handy if you take a hit.
- Spot the Cave: Look for cave entrances, often nestled in the seabed or sides of cliffs. Pay attention to the terrain – the entrances are usually surrounded by the familiar reddish-brown sulfur deposits.
- Scout Ahead: Before diving in headfirst, use your scanner to pinpoint the location of the Cave Sulfur and any nearby Crashfish. Knowledge is power!
- The Dash and Grab: This is where your Seaglide comes in handy. Quickly swim towards the Cave Sulfur, grab it FAST, and then boost away before the Crashfish can reach you. Think of it as a high-stakes game of tag, where the loser gets exploded.
- Rinse and Repeat: Don't get greedy! Grab one or two pieces of sulfur per cave visit. Too many trips in and out and the Crashfish will get wise to your game.
Pro Tip: Some players find it useful to carry a spare piece of metal salvage to throw at a Crashfish to distract it. It’s like giving a toddler a shiny object to keep them occupied… except this toddler explodes.
Cave Sulfur: Not Just For Explosions
While the primary use of Cave Sulfur is for defense (torpedoes) and protection (reinforced suit), remember that every little bit counts. In the grand scheme of surviving on an alien ocean, every resource you gather helps you progress and tells a tale of your perserverence. Every piece of sulfur you snag is a step closer to conquering the depths, facing down the leviathans, and ultimately, finding your way home.
So, gear up, dive in, and remember to watch out for those pesky Crashfish. Happy scavenging!
