That will get you the Prawn MK1 which will get you to the upper lava zone down to 1200 meters to get Kyanite which. which you can get easily with the unmodified Prawn. You get nickel in the upper part of the lost river, ABOVE 900 meters, sulfur in the same place. Players can craft this handy upgrade at a Modification Station using 1 Plasteel Ingot, 3 Rubies, and 1 Seamoth Depth Module MK 2. Prawn MK2 will take you to 1700 meters, where none of that is found. Just like with the other depth and pressure-related modules, the Seamoth Depth Module MK 3 will enable the specified vehicle, in this case, the Seamoth, to travel deeper underwater, however, this MK 3 variant allows one to safely dive a massive 700 meters further down than before. To craft it, players will need to use 1 Plasteel Ingot and 3 Rubies with the Cyclops Upgrade Console. Similar to the Prawn Suit Pressure Compensator MK 1, the Cyclops Depth Module MK 1 grants the ability to travel further into the abyss by 400 meters due to increasing hull integrity. It can be accessed from the Deep Purple Vents or Lilypads Crevice (Northern tunnel from Marguerit Maidas Base).

The biome serves as the only entrance to the Fabricator Caverns as well as the location of the Crystal Caves Cache. A single unit of this upgrade will allow one's Prawn Suit to travel 400 meters deeper thanks to increased hull integrity. The Crystal Caves is a biome within Subnautica: Below Zero. The Inactive Lava Zone is characterized by large, arching structures and walls of hardened lava with occasional steaming lava. It is the second deepest biome and the penultimate area in Subnautica.

PDAThe Inactive Lava Zone is a cavernous biome located 900 meters below the surface. So it was asked that I do a guide for finding Nickel Ore in Below Zero. The volcanic rock which has formed in this area can be carbon-dated to between 800 and 3,000 earth years ago. If players want to descend further into the depths with their Prawn Suit, it is recommended to use 1 Plasteel Ingot, 3 Nickel Ore, and 2 Rubies to craft the Prawn Suit Pressure Compensator MK 1 using a Vehicle Upgrade Console. In Subnautica it was pretty abundant in certain areas, and we could even find drillab.
