Getting your first set of Fins in Subnautica 2 feels like a massive upgrade after crawling through the water at base speed. I remember spending my first 30 minutes swimming in circles around my Lifepod, completely missing the glowing orange plants sitting just 84 meters away. This guide covers exactly how to get Lucifer Rotsac in Subnautica 2, where to find it, and what you can craft once you have it in your inventory.
Lucifer Rotsac is essential for early game progression because it is the primary ingredient for crafting Rubber. Rubber then unlocks Fins, Air Tanks, and the Air Bladder – basically everything you need to stop feeling like a stranded diver and start exploring the ocean properly.
By the end of this guide, you will know exactly where to look, how to harvest without any tools, and the step-by-step process for turning this resource into the equipment upgrades you need.

What Is Lucifer Rotsac
Lucifer Rotsac is a crafting material in Subnautica 2 that grows inside Cradle Shootroot plants. These plants appear as large, teal, antler-like structures rooted to the seabed, and each one contains a glowing orange center that holds the resource you need.
Visually, Cradle Shootroot stands out because of its distinctive glowing orange interior. The plant itself looks like a cluster of curved, antler-shaped branches in a teal or blue-green color. When you swim closer, you will see the orange glow emanating from pods nested within the branches. This glow makes the plant relatively easy to spot even in darker waters.
The name confuses some players because you are technically harvesting the Lucifer Rotsac from inside the Cradle Shootroot plant, not harvesting the plant itself. Think of it like picking fruit from a tree – the tree stays, but you collect what is inside.
Where to Find Lucifer Rotsac in Subnautica 2
The closest Lucifer Rotsac location to your Lifepod sits approximately 84 meters away toward the 120-meter depth marker. I found this information through community testing on the Subnautica subreddit, and it matches my own experience – you do not need to swim far from your starting point to find your first cluster.
Look for Cradle Shootroot plants in these specific environments:
- Near rock formations on the seabed
- Areas around 50 meters deep and below
- Open seabed areas, not just confined to caves
- Near decrepit outposts and abandoned structures
- Both natural environments and around man-made buildings
Forum players report that Lucifer Rotsac becomes more abundant once you reach approximately 50 meters deep. However, you can find it in shallower waters too, especially near those first rock formations you encounter swimming away from your Lifepod.
One important visual cue: the glowing orange center makes these plants visible from a distance. Turn up your brightness slightly if you are having trouble spotting them in murky water.
How to Harvest Lucifer Rotsac
No tools are required to harvest Lucifer Rotsac in Subnautica 2. Simply swim up to a Cradle Shootroot plant, position yourself near the glowing orange center, and interact with it. Your character will automatically collect the resource.
Each Cradle Shootroot plant yields exactly 1 Lucifer Rotsac when harvested. This means you need to find multiple plants if you want to stockpile resources for crafting multiple items. I recommend grabbing every plant you pass during early exploration – you will need more than you think.
The good news is that Lucifer Rotsac plants eventually regrow. If you find a convenient cluster near your base, mark it with a beacon and return later for more. Respawn timers vary, but most resource plants in Subnautica 2 take several in-game days to regenerate.
Important warning: Do not confuse Lucifer Rotsac with Cherimoya Rotsac. These look similar but are different resources used for different recipes. Lucifer Rotsac comes from the teal antler-like Cradle Shootroot with the orange glow. Cherimoya Rotsac grows from different plants and has a different visual appearance.
How to Craft Rubber from Lucifer Rotsac
Crafting Rubber is straightforward once you have your Lucifer Rotsac harvested. Follow these steps:
Step 1: Access your Fabricator. This is the circular device inside your Lifepod or at any base you build.
Step 2: Navigate to the “Basic Materials” tab in the Fabricator menu.
Step 3: Select “Rubber” from the available recipes.
Step 4: Click “Craft” to convert your Lucifer Rotsac into Rubber.
The recipe requires 1 Lucifer Rotsac to create 1 Rubber. This is a direct 1:1 conversion, so plan your gathering accordingly. If you want to craft Fins and an Air Tank, you need at least 4 Lucifer Rotsac total (2 for Fins, 2 for the Tank).
One common mistake new players make: trying to craft Rubber before they have actually harvested Lucifer Rotsac. The Fabricator only shows recipes for which you have the base materials in your inventory. If you do not see Rubber in your Basic Materials tab, check that you have Lucifer Rotsac in your personal inventory and not just stored in a nearby locker.
How to Craft Grease from Lucifer Rotsac
Many players miss this entirely, but Lucifer Rotsac also crafts into Grease. This alternate recipe is useful for different crafting requirements later in the game.
Here is how to craft Grease:
Step 1: Open your Fabricator.
Step 2: Navigate to “Basic Materials.”
Step 3: Look for “Grease” in the recipe list.
Step 4: Select and craft.
The Grease recipe also uses 1 Lucifer Rotsac for 1 Grease. You cannot convert Rubber back into Lucifer Rotsac or convert between Rubber and Grease, so decide which material you need before crafting. Rubber takes priority early game because it makes your essential mobility equipment.
I recommend crafting Rubber first until you have your core loadout, then switch to crafting Grease when you unlock recipes that specifically require it.
What Rubber Is Used For in Subnautica 2
Rubber is a component in several essential early-game crafting recipes. Here is what you can make once you have Rubber in your inventory:
Fins: Requires 2 Rubber and 1 Silicone. Fins increase your swimming speed by approximately 15 percent, making exploration significantly faster and less tedious.
Standard Air Tank: Requires 2 Rubber and 1 Titanium. This increases your oxygen capacity from the default 45 seconds to 90 seconds, doubling your dive time.
Air Bladder: Requires 1 Rubber and 1 Silicone. This deployable item rapidly pulls you to the surface when activated, useful for emergency escapes from deep water.
Wakemaker: A tool that creates a pulse wave, useful for certain underwater interactions.
My recommendation for your first crafting priorities: make Fins first, then the Standard Air Tank. The speed boost from Fins makes everything else feel easier, and the extra oxygen gives you more time to find additional resources.
Efficient Farming Tips for Lucifer Rotsac
Stockpiling Lucifer Rotsac early saves you from tedious backtracking later. Once you find your first cluster of Cradle Shootroot plants, harvest everything in sight. Do not just grab one or two – fill your inventory.
Here is my recommended early game farming route: Start at your Lifepod and swim toward the 120-meter depth marker. Mark any Cradle Shootroot clusters you find with beacons or by memorizing landmarks. Continue in a spiral pattern outward from your Lifepod, checking rock formations along the way.
Remember that plants respawn over time. If you are running low on Rubber later in the game, return to your earlier farming spots. The resources will have regrown.
One final warning: always double-check that you are harvesting from the correct plant. Cherimoya Rotsac looks similar but grows from different flora. If your crafting recipes are not working, verify that you actually have Lucifer Rotsac and not Cherimoya Rotsac in your inventory.
Troubleshooting Common Issues
If your Rubber recipe will not craft, check these common causes:
- Verify you have Lucifer Rotsac in your personal inventory, not just in a storage locker
- Make sure you are looking under “Basic Materials” in the Fabricator
- Confirm you are not confusing Lucifer Rotsac with Cherimoya Rotsac
- Check that you have not already crafted all your resources into Grease instead of Rubber
If the recipe simply does not appear in your Fabricator, you likely do not have the base material in your inventory. Pick up some Lucifer Rotsac and check again.
Frequently Asked Questions
Does Subnautica 2 have Leviathans?
Yes, Subnautica 2 features Leviathan-class creatures, though their locations and behaviors differ from the original game. Early game areas around the Lifepod are generally safe from these massive predators.
What is the hardest item to get in Subnautica?
Items requiring deep biomes and rare resources present the biggest challenges. Late-game materials like Kyanite or items from the Lost River biome require significant preparation, specialized vehicles, and advanced equipment.
How to find fibrous pulp in Subnautica 2?
Fibrous Pulp comes from harvesting certain underwater plants and coral structures. Look for bulbous, fibrous-looking vegetation in the shallower biomes near your starting location. It is used for crafting Silicon and other basic materials.
Is the reaper Leviathan in Subnautica 2?
The Reaper Leviathan from the original Subnautica does not appear in Subnautica 2. This sequel features different Leviathan-class creatures native to the new planet and biome structure.
Summary
How to get Lucifer Rotsac in Subnautica 2 is straightforward once you know what to look for. Swim approximately 84 meters from your Lifepod toward the 120-meter depth marker, watch for teal antler-like Cradle Shootroot plants with glowing orange centers, and interact with them to harvest. No tools required.
Convert your Lucifer Rotsac into Rubber at the Fabricator under Basic Materials, then use that Rubber to craft essential early game equipment like Fins and Air Tanks. Do not forget that Lucifer Rotsac also crafts into Grease for alternate recipes.
Stockpile this resource whenever you find it – the plants regrow, but running out mid-exploration is frustrating. Mark your favorite farming spots with beacons and return as needed.
Now get out there and stop swimming at base speed.
