Early Game Survival: How to Get Acidic Raion Pouch in Subnautica 2

In the early stages of Subnautica 2, finding an Acidic Raion Pouch is one of your most critical first steps. You need this resource to craft the basic battery, which powers your scanner—the arguably most important tool in your arsenal. Without a scanner, you cannot unlock essential blueprints like the Wakemaker propulsion device or the Sonic Resonator, effectively locking you out of deeper progression.

The good news is that you do not need to venture far into the dangerous depths to secure this item. Once you know the correct harvest mechanics and spawn locations, you can efficiently gather what you need to kickstart your survival journey.

Harvesting Mechanics and Safety

To collect this resource, you must target purple, brain-shaped plants known as Acid Raion. These plants are frequently found in cave environments and serve as a reliable early-game node.

Crucial Harvesting Rule: You must cut away the Acidic Raion Pouches first. If you harvest the central Medical Gel Sack before the pouches, the plant will spew burning acid into the surrounding water, potentially damaging you and your gear. Always prioritize the pouches to avoid this hazardous reaction.

Each Acid Raion plant typically yields multiple pouches, meaning you rarely need to harvest more than one or two plants to get what you need for your initial battery crafting.

Best Early-Game Spawn Locations

Right after leaving your starting Lifepod, several Acid Raion clusters are positioned within easy swimming distance. These locations are ideal for players who have just crafted their Survival Multitool and are ready to explore slightly beyond the immediate crash site.

  • Directly Beneath the Lifepod: There are two Acid Raion plants located in the cave system immediately below your starting point.
  • East of the Lifepod: Move approximately 30 meters east into the lower level of the adjacent cave. You will find two more plants here, located just past an acid-spewing plant that serves as a natural landmark.
  • The Welcome Centre: Head 70 meters southeast from the Lifepod to the Welcome Centre structure. Multiple Acid Raion plants grow under and around this area, offering a dense cluster of resources.

While these locations are unbeatable for convenience in the first few hours, you will encounter Acid Raion in droves as you swim further away from your base once you have unlocked upgrades like the oxygen tank and flippers.

Why This Resource Matters

The primary purpose of collecting Acidic Raion Pouches is to craft batteries. These are a universal requirement for almost every handy tool in Subnautica 2, including:

  • The Scanner (for unlocking blueprints)
  • The Flashlight
  • The Habitat Builder
  • The Wakemaker propulsion device

Beyond batteries, Acidic Raion Pouches are also used to craft Mild Acid, a chemical component required for various advanced recipes. Additionally, the Medical Gel Sack found at the center of the plant is vital for crafting more advanced first-aid kits, making it a valuable secondary harvest if you remember to take it safely.
