- Beware of Marrow Breach fauna in dangerous lithium-rich zones.
Early Game Subnautica 2 Lithium Location: The Great Jaw
Finding lithium early in Subnautica 2 can be a challenge, as it typically appears in hotter, deeper zones. However, there's a unique early-game spot that allows you to collect this vital resource before acquiring advanced heat adaptations: The Great Jaw. This location is ideal for crafting your first Plasteel Ingots and upgrading your air tank.
Video Highlights:
- Requires Sonic Resonator, High-Capacity Air Tank, Basic Fins, and Wakemaker.
- Head southwest from the Lifepod, following the crater wall.
- Look for a ruined colony building and a fragment of coral dome with lithium.
- The Great Jaw itself is a giant clam-like structure with lithium inside.
- Be quick: the jaw closes when you touch its purple tendons.
The Great Jaw is situated roughly 350 meters south-southwest of the Lifepod, near a large wreckage where you can find part of the repair tool blueprint. Beyond this wreck, you'll spot a giant clam-like organism with a hollow node in its center, covered in bright purple tendons. This is where you'll find early lithium deposits.
The Great Jaw is a perilous spot. Its sides will begin to close the moment you touch a tendon. If you don't escape in time, it can be fatal. It's highly recommended to save your game before attempting to harvest here.
Preparing for The Great Jaw Expedition
To safely extract lithium from The Great Jaw, you'll need specific gear and a strategic approach.
| Item | Purpose | Notes |
|---|---|---|
| Sonic Resonator | Required to break large lithium deposits | Essential for harvesting lithium. |
| Standard Air Tank | Provides sufficient oxygen for the dive | Upgrade to High Capacity if possible. |
| Basic Fins | Increases swim speed | Crucial for quick escapes from the closing jaw. |
| Wakemaker | Enhanced mobility gadget | Provides a dash ability for faster movement. |
| Air Bladders | Backup oxygen supply | Useful if you get disoriented or need extra time. |
| Flares | Distraction for aggressive fauna | Can deter Marrow Breaches if encountered. |
Before entering The Great Jaw, ensure your oxygen levels are full. There are often Oxygen Tunics around the outside of the jaw that you can use to refill your O2.
Extraction Strategy
Locate The Great Jaw
From your Lifepod, head approximately 350 meters south-southwest. Look for a large wreckage site, and beyond it, the distinctive clam-like structure of The Great Jaw.
Equip Your Tools
Ensure you have the Sonic Resonator equipped. Have your fins and Wakemaker ready for maximum mobility.
Enter and Harvest
Swim into the hollow node. The lithium deposits are typically found within the "tonsil" structure. As soon as you touch the purple tendons, the jaw will start to close.
Smash and Grab
Quickly use your Sonic Resonator to break a few lithium blocks. Aim for 1-2 pieces per run to minimize risk.
Rapid Escape
Immediately after harvesting, use your enhanced mobility (fins, Wakemaker dash) to swim out of the closing jaw. The jaw will reopen after a few moments, allowing you to return for more if needed.
Best Lithium Farming Spots: Tadpole Pens & Hot Caves
Once you've advanced further in Subnautica 2 and acquired the necessary Heat Adaptation (such as the Angel Comb mutation), significantly richer lithium deposits become accessible. These are primarily found in the warmer waters and volcanic vent zones around the Tadpole Pens.
The most efficient farming location for lithium is a large cave system situated approximately 550 meters southeast of the Lifepod and 600 meters southeast of Ruby's Blackbox. This cave is visited during the main story when searching for Zip's Blackbox, making it a familiar landmark.
| Location Feature | Distance from Lifepod | Key Characteristics | Required Gear | Fauna Threat | Yield Potential |
|---|---|---|---|---|---|
| The Great Jaw | ~350m SW | Early-game, dangerous closing mechanism | Sonic Resonator, Fins, Wakemaker | Low (jaw itself) | Moderate |
| Tadpole Pen Caves | ~550m SE | High-yield, hot environment, deep | Heat Adaptation, Sonic Resonator, Tank | Marrow Breach | High (20+ nodes) |
| Wander's Blackbox | ~300m E | Scattered deposits, near heat sources | Heat Adaptation, Sonic Resonator | Marrow Breach | Moderate |
The hot caves near the Tadpole Pens offer an abundance of lithium. Many nodes can be found at the cave entrance and deeper within, particularly at the base of rock formations. Each node typically yields two pieces of lithium.
Navigating the Hot Caves
These areas are often patrolled by dangerous fauna like the Marrow Breach. These creatures are territorial and can pose a significant threat, especially if they work in groups.
Marrow Breach Behavior
- Known to patrol the "top hole" entrance to deep areas.
- Can follow players out of caves and strike unexpectedly.
- Exhibit curious behavior, often waiting for an opportune moment to attack.
Evasion Tactics
- Carry flares to distract or deter aggressive fauna.
- Maintain situational awareness and scan your surroundings.
- If pursued, head back towards the Lifepod (west) as a safe retreat.
Lithium deposits in these deeper, dimmer areas can sometimes be mistaken for lead. Look for these distinguishing features:
- Lithium: Burnt red at the top, tapering into a light orange base; resembles long rectangles clumped together.
- Lead: Square protrusions; generally appears darker and more uniform.
Essential Preparations for Deep Dives
To maximize your lithium haul and ensure your survival in these challenging environments, consider the following checklist:
Deep Dive Lithium Farming Checklist:
- Acquire Heat Adaptation (e.g., Angel Comb mutation)
- Craft and equip a Sonic Resonator
- Upgrade to a High-Capacity Air Tank
- Carry multiple Air Bladders for emergencies
- Bring several flares for creature deterrence
- Ensure your Tadpole vehicle (if used) has sufficient depth upgrades
- Enable all landmark signals in the character menu for easier navigation
Remember that while the Tadpole Pens signal might disappear from your log after completing the associated mission, you can still navigate using your Lifepod and Ruby's Blackbox as reference points.
Lithium Uses & Crafting
Lithium is a critical resource in Subnautica 2, primarily used in the fabrication of Plasteel Ingots. These ingots are essential for numerous upgrades and advanced crafting recipes, making lithium a high-priority material.
Key Crafting Recipes
| Item | Materials Required (Partial) | Primary Use | Impact on Gameplay |
|---|---|---|---|
| Plasteel Ingot | 1x Lithium, 1x Titanium | Advanced components, vehicle upgrades | Enables construction of stronger, more durable gear. |
| High-Capacity Dive Tank | 1x Plasteel Ingot, 2x Glass | Increased oxygen capacity | Longer exploration times, safer deep dives. |
| Vehicle Upgrade Modules | Plasteel Ingots, various | Enhances Tadpole performance (depth, speed) | Access deeper biomes, evade threats more easily. |
| Advanced Base Modules | Plasteel Ingots, various | Stronger and more complex base structures | Improved safety and functionality for your base. |
Prioritize crafting the High-Capacity Dive Tank as soon as you have enough lithium for one Plasteel Ingot. This upgrade significantly improves your early-game exploration capabilities.
Visual Identification of Lithium
Distinguishing lithium from other resources, especially in dimly lit underwater environments, is important. While lead can appear similar, lithium has distinct characteristics:
- Coloration: Burnt red at the top, fading to a lighter orange at the base.
- Shape: Resembles a cluster of long, rectangular chunks.
- Texture: Often appears as large, beefy mineral deposits requiring the Sonic Resonator.
In some dark caves, lead might look similar to lithium. Always remember that lead has distinct square protrusions, whereas lithium is characterized by its elongated, clumped rectangular forms.
Advanced Tips for Lithium Acquisition
Mastering lithium collection involves more than just knowing where to go; it requires efficient techniques and environmental awareness.
Efficient Harvesting
- Focus on clearing entire nodes for maximum yield.
- Each node typically provides two pieces of lithium.
- Recharge oxygen and save frequently, especially in dangerous zones.
Environmental Awareness
- Pay attention to biome cues (temperature warnings indicate lithium presence).
- Use flares to distract aggressive fauna like Marrow Breaches.
- Always have an escape route planned, particularly from enclosed spaces.
Gear Optimization
- Keep your Sonic Resonator fully charged.
- Ensure your High-Capacity Air Tank is always equipped.
- Consider upgrading your Tadpole's depth module for deeper cave access.
If you ever feel lost in the labyrinthine caves, remember that your Lifepod is generally to the west from the Tadpole Pen area. Use this as a reliable navigation point to return to safety.
