Subnautica 2 Strong Acid — How to Make & Uses

Subnautica 2 — current release build

Overview

A highly reactive chemical compound synthesized in the Processor. Strong Acid is a critical mid-game material used in Power Cells, Dedicated Cores, Fiber Mesh, and Scout Ray vehicle construction. It has two crafting paths: the preferred route uses Necrolei Cysts (a renewable biological resource), while the alternative requires Sulfur and Gold — both of which are needed elsewhere.

IngredientQtyHow to Get
Necrolei Cyst×2Preferred route: faster (30s) and more renewable. Harvested from Necrolei formations in deeper water.

Where to Find Strong Acid

Deep Water (150m+)

Best Spot

Necrolei Cysts are harvested from Necrolei formations — large purple weed-like organisms found in deeper biomes past the Alien Ruins region. Each formation yields multiple cysts.

⚠ Important Notes

  • Alternative recipe: 1× Sulfur + 1× Gold → Strong Acid (60s). Only use this if Necrolei Cysts are unavailable — Gold is required for other advanced recipes.

Tips

  • Use Necrolei Cysts over the Sulfur + Gold route whenever possible — it's faster and Gold is a bottleneck resource.
  • Dedicated Core requires Strong Acid and is itself needed for Power Cells and the Scout Ray — batch-produce Strong Acid before vehicle building.
  • Power Cells (which use Strong Acid) are required for the Tadpole — plan your Strong Acid pipeline early.
  • Stock at least 4–6 Strong Acid before starting the Scout Ray build chain.
