I surfaced in the coral dome with air ticking low and a Survival Multitool that squeaked when I swung it. You can feel the game narrow to a single choice: harvest the plant or swim back to base empty-handed. That hesitation is where most new runs stall, and where you can take control.
The coral cave just northeast of your Lifepod holds the first lead — How to get Acidic Raion Pouch in Subnautica 2
I’ll say this plainly: you need Acidic Raion Pouches early, and you’ll want a plan. You get them from Acid Raion plants, the large pink growths with brain-like pouches at their base. Each plant gives up to three pouches and hides a Medical Gel Sac in its center, which doubles as a useful emergency med resource.

Start simple: craft a Survival Multitool. The recipe is three titanium. Titanium is everywhere on the seabed—scrap it from metal debris and small ore nodes—so you’ll have the parts fast. Head to your Fabricator, build the tool, then return to the caves.
Where can I find Acidic Raion Pouch?
Most Acid Raion plants sit inside caves around your Lifepod. One reliable spawn sits inside a Coral Dome cave directly northeast of the starting spot. There’s also a plant outside a window at the Welcome Center, about 80 meters southeast of your Lifepod, and another beneath that structure in the cave below. Move slowly; some plants tuck themselves in alcoves or behind rock ledges.
When you cut the plant with the Survival Multitool it drops the pouches—three per plant—plus the Medical Gel Sac. That makes every plant worth the short trip.
How many Acidic Raion Pouches do I get per plant?
Each plant reliably yields three pouches. If you’re hoarding batteries or building processors early, that yield shapes your immediate resource math: three pouches per plant lets you craft several Basic Batteries or mix Mild Acid recipes without long farm runs.
Think of an early Acidic Raion find as a spare battery in a dead phone—small, but it buys you minutes that feel like hours. The plant itself is a neon lollipop in the gloom; it’s obvious once you’ve been there, but easy to miss if you rush.
The way your toolkit changes choices at 10 meters depth — All Acidic Raion Pouch recipes in Subnautica 2
There aren’t many recipes that use Acidic Raion Pouch, but the ones that do shape your early game. Treat each pouch like currency: spend it on batteries for tools or on Mild Acid for processors.
- Basic Battery: Copper + Acidic Raion Pouch
- Mild Acid: Acidic Raion Pouch + Copper
- Mild Acid (Processor recipe): Acidic Raion Pouch
Basic Batteries power nearly every handheld and early base item, so the copper+pouch combo is often your first stop. Mild Acid feeds into processors and the biolab, which matter if you plan to push into crafting electronics and research sooner rather than later.
If you want community-driven locational tips, check Steam guides and the Subnautica 2 threads on Reddit—Unknown Worlds’ forums also host maps and spawn screenshots that match the Welcome Center and Lifepod coordinates I described. The Moyens I/O screenshot above is a quick visual cue for what to hunt.
So here’s the trade-off I leave you with: will you spend the pouches on a handful of batteries to keep tools running, or will you grind a few extra plants to reserve pouches for processors later—what’s your play?
