Subnautica 2 Necrolei Cyst Location Guide
Necrolei Cysts (or as some call them "necrotic cysts") in Subnautica 2 are harvested from Stilt Orbs, the green orb shaped plants with long neon pink tendrils found near the first major Angel Comb route. They are mainly needed for Strong Acid, which becomes important for Power Cells and Tadpole progression.

Where To Find Necrolei Cysts In Subnautica 2
Necrolei Cysts are found inside Stilt Orbs near the first mandatory Angel Comb area, roughly northwest of the Lifepod and near the route between the Lifepod, Wander’s Blackbox, and the Tadpole Pens.
The easiest way to think about the location is to look for the giant Angel Comb area first, then search nearby for green spherical plants with long neon pink tendrils. These plants are Stilt Orbs, and the Necrolei Cysts are harvested from inside them.
| Item | Source | Location Clue | Main Use |
|---|---|---|---|
| Necrolei Cyst | Stilt Orb | Near the first major Angel Comb route, northwest of the Lifepod | Crafting Strong Acid |
One listed location places the Stilt Orb cluster about 255 meters northwest from the Lifepod near the giant Angel Comb, with coordinates around -355008, 414805, -3683. Another useful route clue is that the cluster is close to the first mandatory Angel Comb and north of Wander’s Blackbox. Either way, the key landmark is the Angel Comb area, not the open shallows.
I would not search random starter caves for this one. Necrolei Cysts are much more specific than basic materials like Titanium or Copper, and the plant can be easy to swim past if the bright tendrils do not stand out right away.

How To Harvest Necrolei Cysts
To harvest Necrolei Cysts, approach a Stilt Orb, use the Survival Multitool to hit the green sphere, then collect the Necrolei Cyst from inside once the plant opens.
The cysts are not loose pickups sitting around the seabed. They are inside the plant. That is why the location can feel confusing at first, because finding the right plant is only step 1. The plant still needs to be opened before the cyst can be collected.
| Harvest Step | What To Do |
|---|---|
| 1 | Find the Stilt Orb cluster near the Angel Comb route. |
| 2 | Swim close to the green orb shaped plant. |
| 3 | Use the Survival Multitool to strike the sphere. |
| 4 | Collect the Necrolei Cyst from inside. |
| 5 | Check every nearby Stilt Orb before leaving. |
Grab every cyst in the cluster before moving on. Necrolei Cysts are rare compared to more common early materials, and returning later because 1 more Strong Acid is needed is exactly the kind of tiny backtrack Subnautica 2 loves to punish.
What Stilt Orbs Look Like
Stilt Orbs are passive sessile lifeforms with a round green body, long thin stilt like legs, and pink blister growths on the top of the orb.
In the water, the easiest visual clue is the green spherical body with long neon pink tendrils trailing around it. That is the plant to inspect. It does not look like a normal mineral node, and it does not behave like a loose resource pickup.
| Stilt Orb Feature | What To Look For |
|---|---|
| Body | Green round orb shape |
| Legs | Long thin stilt like supports |
| Color clue | Pink blisters or neon pink tendril shapes |
| Behavior | Passive plant like lifeform |
| Resource | Necrolei Cyst inside the orb |
The Stilt Orb is the real search target. Once that shape is recognized, the Necrolei Cyst route becomes much easier.
Best Route From The Lifepod
The best Necrolei Cyst route is to head northwest from the Lifepod toward the giant Angel Comb area, then search around the nearby Necrolei Zone for Stilt Orbs.
The route can also be checked from the Wander’s Blackbox side. The Stilt Orb cluster is described as being near the first mandatory Angel Comb, about 90 meters north of the Angel Comb signal and around 300 meters north of Wander’s Blackbox. That gives 2 useful landmark checks if the Lifepod route feels vague.
| Route Landmark | How It Helps |
|---|---|
| Lifepod | Use this as the starting point and head northwest. |
| Giant Angel Comb | The main landmark near the Stilt Orb area. |
| Wander’s Blackbox | A nearby route reference if already discovered. |
| Stilt Orb cluster | The actual source of Necrolei Cysts. |
The route is not about depth alone. It is about finding the right plant cluster near the right story and adaptation landmarks. If the area has no green orb plants with pink tendrils, keep checking around the Angel Comb zone instead of farming random plants.
What Necrolei Cysts Are Used For
Necrolei Cysts are used to make Strong Acid, which is needed for important power and vehicle related crafting in Subnautica 2.
Strong Acid becomes important because it connects to Power Cells. Power Cells are used for the Tadpole and other energy hungry devices, so Necrolei Cysts are not just a random plant material. They feed directly into better exploration and vehicle support.
| Necrolei Cyst Use | Why It Matters |
|---|---|
| Strong Acid | Needed for advanced crafting beyond Mild Acid. |
| Power Cells | Strong Acid is part of the chain for important power crafting. |
| Tadpole progression | Power Cells support the vehicle path and deeper exploration. |
Once a base is built, a Power Cell terminal can reduce how often new Power Cells need to be crafted. That makes the Subnautica 2 Habitat Builder guide a useful next step if power management is starting to matter.
How Necrolei Cysts Connect To Strong Acid
Necrolei Cysts are one of the key materials needed for Strong Acid, and 2 Necrolei Cysts are needed to make 1 Strong Acid.
The Fabricator only makes Mild Acid, so Strong Acid requires the Processor first. That means Necrolei Cysts may be found before the full crafting chain is ready. If the recipe is not available yet, the missing piece is likely the Processor progression.
The full Strong Acid route is covered in the Subnautica 2 Strong Acid guide, which is the better page for the full recipe and crafting chain.
| Strong Acid Step | What It Means |
|---|---|
| Collect Necrolei Cysts | Harvest them from Stilt Orbs near the Angel Comb route. |
| Unlock the Processor | Strong Acid is made through the Processor, not the basic Fabricator. |
| Craft Strong Acid | Use 2 Necrolei Cysts for 1 Strong Acid. |
| Use it for power crafting | Strong Acid supports Power Cell and Tadpole progression. |
If Processor progression is still blocked, the Subnautica 2 Titanium Ingots guide covers the Processor route and the crafting setup tied to processed materials.
Necrolei Cyst Farming Tips
The best Necrolei Cyst farming habit is to collect every cyst in the Stilt Orb cluster once the location is found.
- Search near the first mandatory Angel Comb route.
- Look for green orb shaped Stilt Orbs with neon pink tendrils.
- Use the Survival Multitool to open the orb.
- Grab every Necrolei Cyst before leaving the area.
- Keep extra cysts for future Strong Acid crafting.
- Do not waste time searching normal shallow caves for this material.
- Unlock the Processor before expecting to craft Strong Acid.
I would stockpile a few more than the first recipe needs. The plants are rare enough that grabbing only the exact amount can turn into another annoying trip later.
Why You Cannot Find Necrolei Cysts
If Necrolei Cysts are not showing up, the player is probably searching the wrong plant, missing the Angel Comb route, or expecting the cyst to appear as a loose pickup.
| Problem | Likely Cause | Fix |
|---|---|---|
| No Necrolei Cysts near the Lifepod | The search is too close to starter materials. | Head northwest toward the giant Angel Comb area. |
| Found the plant but no cyst | The Stilt Orb has not been opened yet. | Use the Survival Multitool to hit the green sphere. |
| Only finding normal plants | The Stilt Orb cluster has not been found. | Look for green spherical plants with neon pink tendrils. |
| Strong Acid recipe is not available | The Processor may not be unlocked yet. | Unlock the Processor before trying to craft Strong Acid. |
| Need more cysts later | Only the minimum amount was collected. | Return to the Stilt Orb cluster and harvest every available cyst. |
Necrolei Cysts are easy to miss because the game asks players to recognize a specific plant instead of a normal mineral node. Once the Stilt Orb shape is known, the route becomes much cleaner.
Final Blurb
Necrolei Cysts in Subnautica 2 are harvested from Stilt Orbs near the first mandatory Angel Comb route, northwest of the Lifepod and near the Wander’s Blackbox path. Look for green orb shaped plants with neon pink tendrils, open them with the Survival Multitool, and collect the cysts from inside.
The main reason to get Necrolei Cysts is Strong Acid. Each Strong Acid needs 2 Necrolei Cysts, and Strong Acid connects to Power Cells, the Tadpole, and later power progression. Grab extra while the Stilt Orb cluster is already found, because swimming back for one missing cyst is the kind of tiny problem that feels personally designed by the ocean.
