This Subnautica 2 Guide shows where to get the Necrolei Cysts for making the strong acid. In Subnautica 2, Necrolei Cysts are an important material to collect because it is needed to craft strong acid, which helps you progress toward stronger equipment upgrades. The good news is that you do not need advanced gear or anything special to get it. As long as you bring your harvesting tool, you can gather everything you need without too much trouble.
Strong Acid Guide – Subnautica 2
Starting from the lifepod area, head toward the northwestern side of the map. Using the lifepod as your main reference point makes the route easier to follow, especially with your base built nearby.
As you move farther away from the starting zone, you will begin noticing the environment changing around you. The sea floor starts to look different, and the plants in the area become more unusual compared to the safer starting biome. Along the way, you may also run into parts of an infection-related objective, since that mission seems to pass close to this region.
Keep moving northwest until large purple plants start appearing around massive rock structures. That is the main sign you are in the correct location. Around these cliffs and plant-covered areas, you will spot small floating growths attached to thin stems. They look almost like glowing fruit or flowers hanging in the water. These are actually the Necrolei Cysts.
To collect the resource, simply use your harvesting tool on the top section of the plant. Hitting the flower-like part will give you the material you need. Several of these plants can usually be found spread around the nearby cliffs, so once you locate one group, you can gather plenty more in the same area without searching too far.
