Exploring the oceanic depths of Planet 4546B in Subnautica presents unique resource gathering challenges that standard hand tools cannot resolve. Utilizing the Pressure Reactive Waterproof Nanosuit, commonly known as the Prawn Suit, allows divers to safely traverse crushing depths while carrying heavy machinery. Equipping this mechanical exoskeleton with the proper attachments is essential for unlocking the planet's most valuable deep-sea mineral reserves.
Locating Drill Arm Blueprint Fragments
Before survivalists can manufacture this high-utility attachment, they must scan two fragmented blueprints hidden among underwater wreckage. These mechanical pieces are most commonly discovered deep within the hazardous Grand Reef wreck or scattered throughout the sand dunes. Explorers should equip a Seaglide and maintain a steady oxygen supply while searching around these debris fields at depths exceeding two hundred meters.
Another reliable area to investigate is the underwater expanse of the Bulb Zone, which hosts multiple shattered hulls containing advanced technology. Scanning these pieces completely unlocks the schematic within the vehicle modification station data bank. Careful spatial awareness is required during these search expeditions to avoid predatory fauna guarding the graveyard sites.
Crafting Requirements at the Modification Station
Once the blueprint is fully archived, drivers must gather specific refined elements to construct the upgrade. Fabrication requires one diamond, five titanium pieces, and one lithium deposit to form the core structural chassis of the device. Additionally, a single piece of copper wire is required to safely integrate the sub-aquatic motorized components with the Prawn Suit power cell.
All collected materials must be brought directly to a Vehicle Upgrade Console housed inside a Moonpool facility. Depositing the raw ingredients into this specific fabricator will instantly yield the heavy mining attachment for deployment. Ensuring your base has sufficient energy grid connectivity is vital before initiating the automated assembly sequence.
Maximizing Mining Efficiency and Combat
The primary function of this heavy machinery is drilling into large mineral outcrops like titanium, copper, and kyanite. Standard hand gathering cannot break these massive geologic formations, making the mechanized drill essential for late-game progression. Holding down the designated input allows the drill bit to continuously grind away until the node collapses into individual transportable items.
While this attachment functions primarily as a harvesting mechanism, it can also serve as a rudimentary defensive weapon against hostile entities. However, standard Prawn Suit fists actually deliver higher burst damage against aggressive leviathans blocking your path. For optimal subterranean exploration, pairing the drill with a grappling arm attachment provides the best balance of mobility and resource extraction capability.
