Core Event: Harvesting Necrolei Cysts and Crafting Strong Acid
Players first scan a Processor to unlock its blueprint, then harvest Necrolei Cysts from Stilt Orbs and process two cysts per Strong Acid in the Processor. Each craft takes 30 seconds and yields one unit of Strong Acid.
Background & Context: Why Strong Acid Is Essential
Strong Acid unlocks Fiber Mesh and is required for the Power Cell that powers the Tadpole mini-sub, making it a prerequisite for advancing beyond early exploration.
Data & Statistics
- Necrolei Cysts per Strong Acid: 2; Processing time: 30 seconds.
- Cyst biome: Stilt Orbs with turquoise flowers at ~25 m depth, located ?300 m NW (GameRant), ?350 m north (PC Gamer), or near the Blackbox – Quaker habitat (Prima Games) from the Lifepod.
- Alternate recipe: 1 Sulfur + 1 Gold, found in the lava biome ?230 m SE of the Lifepod; requires the Heat Tolerance adaptation.
Official In-Game Guidance
The AI NOA directs players to the Old Habitat to retrieve a black box, which is located near the Necrolei Cyst area. The Scanner Station base module can pinpoint Necrolei Cysts when deployed. Crafting the Processor itself requires 2 Titanium, 1 Mild Acid, and 1 Copper Wire, after which the Strong Acid recipe appears in the Refinement category.
Conflicting Reports & Gaps
Source descriptions of the cyst biome differ: PC Gamer places the Old Habitat 350 m north of the Lifepod; GameRant specifies a 300 m NW vector; Prima Games references proximity to the “Blackbox – Quaker habitat” without a precise bearing. No source provides exact coordinates for Sulfur and Gold beyond a general lava-biome location, leaving a navigation gap for the alternate recipe.

What’s Next: Alternate Production Path
Players who have unlocked the Heat Tolerance adaptation can harvest Sulfur and Gold in the lava biome and use the alternate recipe, reducing reliance on Necrolei Cysts. This route reduces dependence on the specific Stilt Orb biome but requires additional progression steps.
