Progressing quickly in Subnautica 2 requires efficient resource collection and vehicle upgrades. To achieve this, you’ll need to craft Strong Acid, which depends on obtaining Necrolei Cysts. This guide provides a step-by-step breakdown of where to find Necrolei Cysts, how to craft Strong Acid, and its key applications in the game.

How to Find Necrolei Cyst in Subnautica 2

The most straightforward method to locate Necrolei Cysts early in the game is to head toward the Old Habitat, a point of interest (POI) situated directly north of your starting Lifepod.

Travel approximately 300 meters north from your Lifepod toward the Old Habitat. In this area, you’ll encounter:

  • Green and pink coral scattered across the seafloor.
  • Small green plants with blue flowers on top, known as Stilt Orbs.

Use your Survival Multitool to break these Stilt Orbs. Each broken plant yields a Necrolei Cyst. Multiple Stilt Orbs are available in this biome, allowing for easy farming of the resource.

How to Make Strong Acid in Subnautica 2

Before crafting Strong Acid, you must first unlock the Processor blueprint, which requires accessing the Old Habitat.

Enter the Old Habitat through a hole located at the base of the structure. Inside, you’ll find several broken Processors. Scan these to unlock their blueprints, enabling you to construct one at your base.

The Processor requires the following materials to craft:

  • Titanium (2 units)
  • Mild Acid (1 unit)
  • Copper Wire (1 unit)

At this stage of the game, Titanium is abundant and easy to gather. Copper Wire is slightly harder to obtain, as copper primarily spawns in caves. To craft Mild Acid, you’ll need Acidic Raion Pouches, which can be harvested from Acid Raion plants using your Survival Multitool.

Once you’ve gathered all the necessary materials, place the Processor in your base. Ensure your base has sufficient power to operate it. Inside the Processor, you’ll find the recipe for Strong Acid, which requires 2 Necrolei Cysts per batch.

How to Use Strong Acid in Subnautica 2

Strong Acid is a versatile resource used in multiple crafting recipes, including upgrades for vehicles and equipment. Below is a complete list of recipes that require Strong Acid:

  • Fiber Mesh: Fiber + Strong Acid
  • Advanced Battery: Conduit Crystal + Strong Acid + Silver Ingot
  • Power Cell: Basic Battery + Strong Acid + Salt
  • Entangled Power Cell: Conduit Crystal + Strong Acid + Gold Ingot + Troilite
  • Dedicated Core: Advanced Wiring Kit + Quartz + Strong Acid

Power Cells are particularly valuable for constructing the Tadpole, a vehicle that enables deeper ocean exploration. Additionally, Fiber Mesh is essential for crafting Improved Fins and the Rebreather, making Strong Acid a critical resource for equipment upgrades.
