Surviving the beautiful yet treacherous waters of Planet 4546B requires a steady supply of advanced resources to upgrade your gear and construct durable underwater bases. Among these essential materials, lithium stands out as a crucial component for crafting reinforced hulls, plasteel ingots, and various vehicle upgrades. Knowing exactly where to locate this resource safely can significantly accelerate your mid-game progression and keep you out of harm's way.
Exploring the Early Mushroom Forest Biomes
The Mushroom Forest is widely regarded by seasoned divers as one of the safest and most abundant locations to harvest raw lithium early in the game. You can find loose pieces of the resource scattered across the seafloor or resting directly on the caps of the giant tree mushrooms. This biome is generally peaceful, allowing you to gather large quantities without constantly evading dangerous leviathans.
For the best results, check both the Northwestern and Northeastern variants of the forest, paying close attention to the base of the massive fungal structures. The low threat level makes it an ideal spot for players who have just constructed their first Seamoth vehicle. Spending a few minutes scanning the terrain here will quickly fill your inventory with the materials needed for your next base expansion.
Venturing Into the Caves of the Mountain Island
Another highly reliable destination for gathering this valuable material is the Mountain Island, located far to the north of your initial crash zone. The extensive cave systems threading through the island contain numerous deposits attached directly to the rocky walls and floors. You can easily pick them up by hand while exploring these dry land tunnels, reducing the risk of running out of oxygen.
However, navigating the surrounding waters requires caution due to the presence of aggressive fauna patrolling the deep coastlines. It is highly recommended to park your vehicle close to the shore before heading inside the subterranean paths to start your harvest. The cave network provides a steady supply that remains accessible even before you acquire deep-diving depth modules.
Searching the Depths of the Jellyshroom Caves
If you possess the proper vehicle upgrades to descend below 200 meters, the glowing Jellyshroom Caves offer a spectacular and resource-rich environment. In this biome, lithium is frequently found contained within shale outcrops or lying loose near the bases of the massive violet mushrooms. The glowing environment makes the distinct silvery pieces relatively easy to spot against the darker seabed.
While harvesting resources in these depths, you must remain mindful of the predatory Crabsnakes that nest inside the giant glowing flora. Keeping a steady eye on your oxygen levels and maintaining a safe distance from their territories ensures a successful expedition. The rewards in this deep cavern are well worth the tactical effort, providing all the materials required for high-tier upgrades.
Alternative Methods for Sustainable Gathering
For players looking to maximize their collection efficiency without constantly exploring dark caves, following the Sea Treader leviathans provides a unique alternative. As these massive creatures walk along their designated path, their heavy steps break up the seabed and continuously unearth fresh shale outcrops. Breaking these outcrops guarantees a steady supply of either lithium or gold with minimal backtracking.
Additionally, constructing a specialized Scanner Room in nearby biomes can drastically reduce your searching time by highlighting precise resource locations on your HUD. This technological approach allows you to plan highly efficient gathering routes, avoiding empty zones and dangerous predators entirely. Utilizing these diverse methods ensures your fabricator never runs out of the materials necessary to conquer the depths.
