- They are found on plants called Stilt Orbs, identifiable by their green color and neon pink tentacles.
- They are essential for manufacturing Strong Acid, a key ingredient in the Energy Cells for the Tadpole vehicle.
- They must be collected using the multitasking survival tool.
- They can be planted at the base to create your own crop and avoid long journeys.
If you're venturing into the depths of Subnautica 2, you'll have noticed that some materials aren't exactly plentiful. Among them are Necrolei cysts , a rather peculiar alien resource that, while not needed in industrial quantities like copper, is essential for advancing the technology of your base and vehicles.
Knowing that they're a bit harder to find than other basic components, it's easy to overlook them while exploring the ocean. To avoid disappointment when you need to craft advanced components, we've prepared this detailed guide so you know exactly where to find them and how to get the most out of them without unnecessary hassle.
Where to locate necrolei cysts?
To find these cysts, you need to look for very distinctive plants called Stilt Orbs . These plants have the appearance of a green sphere supported by striking neon pink tentacles or roots, which become especially vibrant at night. If you see a forest of bright pink corals, you're on the right track.
One of the clearest areas to find them is the area between the Lifepod and the Tadpole's quarters. Specifically, you can search about 90 meters north of the first mandatory Angel Comb marker and approximately 300 meters north of Wander's black box.
Another key location is the Ancient Habitat area. Upon arriving there, if you move a few meters west, you'll find a plateau overlooking the facility where these plants are abundant. The best collection point is the western edge, just before the terrain drops sharply into the depths, where several patches of Stilt Orbs cluster.
How to collect and cultivate the material
An important detail is that you can't simply grab the cyst with your hand or use the sonic resonator to obtain it. To get the resource, you must have a gathering tool equipped , such as the survival multitasking tool. Basically, you have to hit the green sphere to make it open and then collect the cyst inside.
Since these materials aren't abundant, it's best to collect all the ones you see each time you visit these areas, as this will save you tedious trips later. Best of all, these plants can be transported and planted at your own base , allowing you to maintain a constant supply without having to swim miles every time you need some acid.
Uses and manufacturing of strong acid
The primary use of Necrolei cysts lies in the creation of strong acid . This component is vital for crafting Power Cells, which are key to powering the Tadpole vehicle and other high-power devices later in the game.
To obtain this acid, you'll need the processor blueprint and to build the machinery, as the standard fabricator only allows you to make weak acid. The recipe is simple: two necrolei cysts processed for 30 seconds will give you a container of strong acid. Alternatively, you could also use gold and sulfur, but since gold requires the Heat Tolerance adaptation, using cysts is the smarter option early in the game.
To optimize your resources, we recommend installing a power cell terminal on your base. This will allow you to recharge existing cells and prevent you from having to constantly use more strong acid to manufacture new cells.
By mastering the location of the neon pink corals and using the multitasking tool, you can ensure a constant flow of strong acid for your power cells , greatly facilitating the construction of the Tadpole submarine and the expansion of your underwater infrastructure by planting these green spheres in your home.
