Magnetite is one of the most essential mid-game raw materials in Subnautica, required for crafting crucial upgrades such as the Scanner Room HUD Chip, Thermal Plant, and Stasis Rifle. Locating this magnetic ore can be challenging for new players because it often spawns in hazardous, deep-sea environments. Understanding where to look and coming prepared with the right equipment will save you time and keep you safe from dangerous fauna.
Top Biomes to Find Magnetite Deposits
The safest and most reliable early-game location to farm Magnetite is the Jellyshroom Cave, accessible via several deep crevices in the Grassy Plateaus. Large amounts of raw Magnetite lie scattered across the glowing purple cave floor and around the base of giant mushrooms. Players should exercise caution when exploring this cavern, as aggressive Crabsnakes nest inside the oversized fungi.
For players exploring deeper waters, the Lost River and the Mountains biomes contain rich supplies of Magnetite. Large resource deposits can also be found in the Mountain Island caves and surrounding slopes, though territorial Reaper Leviathans patrol nearby. Equip a Seaglide or Seamoth to quickly maneuver past threats while searching the seabed.
Essential Equipment and Mining Strategies
Harvesting loose Magnetite nodes only requires a standard inventory slot, but collecting large ore deposits requires a Prawn Suit equipped with a Drill Arm. Building a Scanner Room near the entrance of the Jellyshroom Cave allows you to easily track individual nodes on your HUD. Using a Seamoth with Depth Module Mk1 lets you stay submerged near the cave ceiling while diving down to collect resources.
Managing your oxygen supply and vehicle energy is vital during deep harvesting runs in narrow cave systems. Carrying a high-capacity O2 tank alongside a Stasis Rifle ensures you can handle unexpected encounters with predators while picking up materials. Stash excess Magnetite inside vehicle storage modules so you can bring back enough supply for all your mid-to-late-game fabrication needs.
Key Crafts and Base Upgrades Utilizing Magnetite
Once secured, Magnetite plays a major role in expanding your power generation and exploration capabilities. It is a primary ingredient in constructing Thermal Plants, which provide clean, perpetual energy for bases built near heat vents. Crafting the Scanner Room range and speed upgrades also heavily relies on this valuable resource.
In addition to base construction, high-tech tools like the Propulsion Cannon and Torpedo System require Magnetite to assemble. Having a steady supply guarantees that you can fabricate top-tier survival gear without constantly making dangerous trips into deep trenches. Plan your gathering trips carefully to keep your crafting reserves well stocked for future adventures.
