Guide Steps
Step 1: Scan Rebreather fragments
Rebreather fragments are found near wrecks in the Kelp Forest (20–40m depth). You typically need to scan 2 fragments to unlock the blueprint. They're small, cylindrical devices often partially buried near wreckage. Use the scanner to check every object near wrecks.
Step 2: Gather materials
Fiber mesh: 2 creepvine samples (harvested from creepvine stalks in Kelp Forest with a knife). Silicone rubber: 1 creepvine seed cluster (found on tall creepvine in Kelp Forest). Both components come from the same biome, so one trip can get everything you need.
Step 3: Craft the rebreather
Fabricator → Equipment → Rebreather. Materials: 1 fiber mesh + 1 silicone rubber. The rebreather is equipped in a head slot and works passively — no power or activation needed. Once equipped, your oxygen depletes slower at depths below 30m.
Step 4: How it works
Without a rebreather, oxygen consumption increases with depth. At 100m, you might consume oxygen 2–3× faster than at the surface. The rebreather normalizes oxygen consumption across all depths, effectively doubling or tripling your dive time in deep biomes.
