Hey guys! So you're diving deep into the mesmerizing, and sometimes terrifying, world of Subnautica and you need sulfur, right? Don't sweat it! This guide will walk you through exactly where to find this essential resource so you can craft those necessary items and keep your adventure going. Let's get started!

What is Sulfur Used For?

First, before we go hunting, let’s talk about why you actually need sulfur. Knowing its uses makes the search feel a bit more purposeful, doesn't it? In Subnautica, sulfur is a crucial ingredient for a few very important recipes. Namely, it's used in crafting:

• Batteries: You’ll need batteries to power up pretty much everything, from your Flashlight to your Seamoth. No power, no progress!
• Power Cells: These are like super-batteries, offering much more juice for your vehicles and tools. Essential for longer expeditions.
• Certain Ammunition Types: Some weapons and tools require specific ammo crafted with sulfur. Think Propulsion Cannon ammo, for example, for clearing out obstacles or dealing with pesky creatures.
• Upgrades: Sulfur sometimes pops up in upgrade recipes, making your gear more efficient or durable.

Without sulfur, you'll find yourself stuck with unpowered tools and vehicles, unable to explore the depths effectively. Therefore, knowing where to find it is paramount to your survival and progression in the game. Finding sulfur early in the game is really important because it allows you to craft those batteries and power cells. With those batteries and power cells, you'll be able to leave your base and find rarer materials that are found deeper in the ocean. You will need the sea moth if you are going to go deep and find materials. The sea moth allows you to attach modules that can protect it from different dangers. Make sure you plan your course accordingly if you need to find certain materials, but always remember to go back to your base to save and recuperate.

Where to Find Sulfur in Subnautica

Okay, let’s get to the good stuff: where to actually find this yellow goodness. Sulfur is typically found inside Crashfish caves. These aren’t marked on your map, and can be a bit tricky to spot at first, but once you know what to look for, you'll be swimming in sulfur in no time. Here's the lowdown:

Crashfish Caves: Your Sulfur Hotspot

The primary place to find sulfur is within Crashfish caves. These small cave systems are inhabited by—you guessed it—Crashfish. These little guys aren’t exactly friendly. They live in the cave and they will charge at you and explode when you get close. So you’ll need to be careful when harvesting sulfur from these locations. Here’s how to handle it:

• Location: Crashfish caves are most commonly found in the Safe Shallows and Grassy Plateaus biomes. These are generally the first areas you'll explore after starting the game, making sulfur relatively accessible early on.
• Appearance: Look for small, dark cave entrances, often nestled amongst coral formations or on the seabed. They're usually pretty discrete, so keep your eyes peeled.
• The Crashfish Threat: As the name suggests, these caves are home to Crashfish. These aggressive creatures will launch themselves out of their plants towards you, exploding on impact. The explosion does a decent amount of damage, especially early in the game, so you'll want to avoid getting hit.

How to Safely Collect Sulfur from Crashfish Caves

So, how do you get the sulfur without becoming fish food? Here’s the strategy:

1. Approach with Caution: Swim slowly and deliberately towards the cave entrance. Keep an eye out for the glowing red plants that the Crashfish live in.
2. Bait the Crashfish: The moment you get close enough, a Crashfish will emerge and swim towards you. The trick is to make it explode away from you. A good tactic is to swim erratically to dodge the fish.
3. Collect the Sulfur: Once the Crashfish has exploded (hopefully not on you!), quickly swim into the cave. You’ll find the sulfur deposits on the walls and floor of the cave. They look like small, yellow crystals.
4. Rinse and Repeat: Be aware that there are usually multiple Crashfish in a single cave. Clear them out one by one, or grab what you can and make a hasty retreat.

Another strategy, if you're feeling brave, is to use the Stasis Rifle. A well-placed shot will freeze the Crashfish in place, giving you ample time to grab the sulfur and get out of dodge. The Stasis Rifle is a very good option to use if you have the resources to make one. It allows you to go into the caves without the risk of being damaged by the crashfish. This is the most effective way to get sulfur. This is because it completely negates the danger that the crashfish poses. With the stasis rifle, you also do not have to wait for the crashfish to explode before getting the sulfur. This significantly increases your efficiency when trying to mine sulfur. However, the stasis rifle does take up a lot of materials to create. Therefore, you should only build it if you have plenty of resources to spare. Also, stasis rifle ammo can be hard to come by if you do not have the resources to craft it. Once you have depleted all the stasis rifle ammo, it can be hard to collect sulfur once again. This is due to the danger that the crashfish poses once again.

Other Potential Locations

While Crashfish caves are your primary source, there are a few other places where you might find sulfur, though they are less reliable:

• Wrecks: Sometimes, you can find sulfur inside wrecks, usually in containers or scattered on the floor. However, this is not a consistent source, so don’t rely on it.
• Loose Deposits: Occasionally, you might find small sulfur deposits lying around on the seabed, particularly in the vicinity of Crashfish caves. Keep your eyes peeled!

Tips for Efficient Sulfur Hunting

Alright, you know where to find it, but let’s maximize your sulfur-gathering efficiency with these handy tips:

• Bring a Buddy (Optional): If you're playing multiplayer, bring a friend! One person can distract the Crashfish while the other gathers the sulfur. Teamwork makes the dream work!
• Carry Extra Inventory Space: Make sure you have plenty of free space in your inventory before heading out. There’s nothing worse than having to leave behind precious sulfur because you're full.
• Be Prepared for Damage: Even if you're careful, you might take a hit or two from the Crashfish. Bring some First Aid Kits to heal up quickly.
• Use a Seaglide: The Seaglide will significantly speed up your movement, allowing you to quickly navigate the caves and escape from exploding Crashfish.

By following these tips, you’ll be swimming in sulfur in no time!

Common Mistakes to Avoid

Even with a guide, it’s easy to make mistakes. Here are some common pitfalls to avoid when hunting for sulfur:

• Underestimating the Crashfish: These little guys are more dangerous than they look! Don’t get cocky and assume you can just swim past them. Always approach with caution.
• Ignoring Your Oxygen: Pay attention to your oxygen level! Crashfish caves are often located deeper underwater, and you don’t want to drown while trying to gather resources.
• Forgetting to Save: This should be a given, but save your game frequently! There’s nothing more frustrating than losing a bunch of collected sulfur because you forgot to save and got blown up by a Crashfish.

Conclusion

And there you have it! Finding sulfur in Subnautica is all about knowing where to look and how to deal with those pesky Crashfish. With this guide, you’ll be well-equipped to gather all the sulfur you need to power your adventure and explore the depths of Planet 4546B. Happy diving, and watch out for those explosions!
