What to know
- Grease is a basic material necessary for early game items like the Wakemaker.
- It can be crafted using one Lucifer Rotsac or two Halfmoon fish.
- Lucifer Rotsacs are found inside glowing orange Cradle Shootroot plants in the shallows.
- You can craft grease immediately using the Fabricator inside your starting lifepod.
In Subnautica 2, securing basic materials is the first step to expanding your underwater capabilities. Grease is a fundamental resource required for crafting early equipment, and gathering the necessary ingredients is a straightforward process once you know what to look for in the starting area.

| Requirement | Detail |
|---|---|
| Primary ingredient | 1 Lucifer Rotsac |
| Alternative ingredient | 2 Halfmoon fish |
| Crafting station | Fabricator |
| Material category | Basic Materials |
| Tool required for harvest | None |
The primary gathering spots for the ingredients are located in the shallow reef areas immediately surrounding your starting lifepod. You will find clusters of star-shaped, teal Cradle Shootroot plants resting on sand patches and rocky outcrops, which house the glowing orange resources needed for this material.
How to gather ingredients for grease
Finding the right resources requires a quick swim outside your pod.
Step 1
Equip your basic diving gear and exit the lifepod into the shallow waters.

Step 2
Look for Cradle Shootroot clusters on the ocean floor, identifiable by their teal, antler-like appearance.

Step 3
Swim close to the plant and interact with the glowing orange orb nestled inside to collect a Lucifer Rotsac, without needing any harvesting tools.

Step 4
Alternatively, you can catch two Halfmoon fish swimming in the same shallow biome if you prefer using the alternate recipe.
How to craft grease at the fabricator
Once your inventory has the necessary organic components, processing them is done back at your base.
Step 1
Return to your lifepod and interact with the Fabricator unit located on the wall.

Step 2
Navigate through the menu by selecting the resources tab, followed by the basic materials section.

Step 3
Select the grease icon so the system can consume either one Lucifer Rotsac or two Halfmoon fish to produce a single unit of grease.

Step 4
Wait for the Fabricator’s progress bar to complete and verify that the item has been added to your inventory before swimming away.

Having a steady supply of this basic material allows you to quickly assemble essential exploration tools. As you continue to harvest from the shallow reefs, stockpiling a few extra units will save time when constructing advanced equipment that requires lubricated parts.
