In Subnautica 2, one of the most critical early-game resources is the Acidic Raion Pouch, which is required to craft basic batteries. These pouches are not only essential for powering tools but also for creating mild acid, making them a priority for new players.
How to Obtain Acidic Raion Pouches in Subnautica 2
Acidic Raion Pouches are harvested from Acid Raion plants, which can be found in specific locations near your starting Lifepod. The closest plant is located inside a Coral Dome cave, northeast of your starting position. To collect the pouches, you will need a Survival Multitool to break apart the plants.

Steps to Craft a Survival Multitool
Before harvesting Acid Raion plants, you must craft a Survival Multitool. This requires:
- 3 Titanium
Titanium is abundant on the ocean floor, so gathering three pieces should be straightforward. Once collected, use your Fabricator to craft the tool before venturing out to search for Acid Raion plants.
Identifying and Harvesting Acid Raion Plants
Acid Raion plants are large, pink organisms with brain-like pouches attached to their base. Each plant yields three Acidic Raion Pouches. Additionally, the center of the plant contains a Medical Gel Sac, which can be used to craft enhanced first aid kits.
These plants are typically found inside caves near your Lifepod. Some are located at the bottom of cave entrances, while others are hidden in small alcoves. Notable locations include:
- The Welcome Center, 80 meters southeast of the Lifepod, which has an Acid Raion plant outside one of its windows.
- A cave beneath the Welcome Center that also contains an Acid Raion plant.
