After crafting the vessel, Al-An will tell you to meet him at the Architect Phase Gate Facility, which is near Outpost Zero. Input the materials into each terminal and start the fabrication process of the vessel. Each terminal is responsible for crafting one part of Al-An’s Vessel. Inside the base on the left side is 3 terminals. The entrance to Fabricator Base is just below 900 meters. Follow either one and try to find a space to park your Seatruck as you will have to leave it. There are two tunnels leading down, each with its own Shadow Leviathan. Fabricator Caverns is located deeper inside the Crystal Caves and can be spotted by its characteristic red-colored crystals. To craft Al-An’s Vessel you need to access the Fabricator Base found in the deepest part of Fabricator Caverns. There are a few other items you can craft with aerogel, but I’ll leave them for you to find in your own playthrough.This is the last part in the process of creating Al-An’s Vessel it is recommended that you bring along the items to craft all 3 parts. Lastly, the Water Filtration Machine can create some salt and filtered water, recovering 50 hydration each. The Thermal Plant is self-explanatory, able to make electricity out of the thermal vents dotted about Subnautica.

It can also mine the large mineral deposits you’ve no doubt come across. With the right upgrades, it can easily face off against a Reaper leviathan, or even a Sea Dragon. The Prawn Suit, if you aren’t aware, is the closest thing to a battle mech in Subnautica. The most useful items that require aerogel are as follows: One is story-related, which I won’t spoil, so you’ll need to get some aerogel at some point or another. What can be crafted with aerogel?Īerogel is used for a few mid-late game items and machines, all of which you’ll be happy to have. After you’ve collected the seeds, pick up the gel sacks, replant them, then rinse and repeat – an infinite supply of gel sacks is yours.

You will be rewarded with a couple of seeds each time. First, plant the gel sacks you obtained during your expedition. With them, you can effectively have an unlimited supply of gel sacks, with a bit of waiting between batches. Once you’ve got a couple of gel sacks, your next priority should be to build a few grow beds at your base. Here’s the entrance you should look out for: A Reinforced Dive Suit will negate this damage. There is some danger, however, as the cave is populated by Tiger Plants, which will shoot damaging barbs at you. In this hole is a cave system, the walls of which are lined with rubies. Roughly 1,000 meters from your Lifepod will be a ridge pockmarked by huge crags, easily visible when near to the surface.Ī little further from these crags is a large hole, with lots of debris surrounding its entrance. If not, simply follow a southwest heading starting from your Lifepod. If you have that beacon active, you’ll easily be able to find the area. One of the most reliable areas I found was located in the Sparse Reef, close to Lifepod 19. The Blood Kelp Zone is another great place, which I’ll talk about later on.įor a more precise excursion, there are a couple of locations that act more or less as a guarantee for rubies. This will lead you mostly to the Grand Reef, Lost River, and the Lava Zones. You should also be checking hotter areas, like the geothermal vents scattered around the map, provided they are sufficiently deep. Rubies can be found no shallower than 200m, though you’ll want to delve a little deeper for more reliable results. They can be used for a few different crafts, allowing you to make depth modules for Subnautica’s three vehicles, a power cell charger, and of course, aerogel.Īlso Read: Best Places to Find Lithium Subnautica Rubies should be the higher priority of the two materials.
