Subnautica 2: How to Get Strong Acid and Necrolei Cysts

Necrolei Cysts are harvested from Stilt Orbs in a specific biome located approximately 300 meters northwest of the Lifepod.

A Processor is required to craft Strong Acid, and the blueprint for it can be found inside the Old Habitat.

Strong Acid is primarily used to create Power Cells for the Tadpole submarine and other useful items like the Rebreather.

Why this matters: Acquiring Strong Acid is a bottleneck in Subnautica 2's progression. It allows players to craft essential items for deeper exploration and resource gathering.

Head approximately 300 meters northwest of the Lifepod. The biome is characterized by large flower-shaped organisms with dark green ridged bodies and pink frills.

Look for Stilt Orbs on the seafloor at roughly 25 meters depth. These are green, onion-shaped bulbs anchored by pink tendrils, with Necrolei Cysts growing as flowers on top.

Unlock the Processor Blueprint: Find broken Processors inside the Old Habitat (north of the Lifepod) and scan them.

Build the Processor: Requires Titanium x2, Mild Acid x1, and Copper Wire x1.

Mild Acid is crafted from Copper and Acidic Raion Pouches at the Fabricator.

Copper Wire is crafted from Copper ore.

2x Necrolei Cyst

Alternative: 1x Sulfur and 1x Gold (requires Heat Tolerance Adaptation, a mid-game unlock).

Power Cell (for the Tadpole submarine)

Fiber Mesh (for Improved Fins and the Rebreather)

Q: Where can I find Necrolei Cysts?

Q: What do I need Strong Acid for?

Strong Acid is vital for early to mid-game progression in Subnautica 2.

Prioritize finding the Old Habitat to unlock the Processor blueprint.

Harvesting Necrolei Cysts is the most accessible way to produce Strong Acid early on.

Power Cells made with Strong Acid are essential for exploring deeper ocean zones.
