1 Why the Rebreather Lets You Go Deeper

🌊

Rebreather

★★★☆☆ — Depth O2 Efficiency
Early-Mid Game

The Rebreather reduces oxygen consumption at depth. Below 100m, your O2 drains faster — the Rebreather counteracts this, effectively giving you more time at depth. Combined with the High Capacity Air Tank, you can explore areas that would otherwise be lethal.

★ What This Means for You

Without the Rebreather, every meter below 100m accelerates your oxygen drain. At 200m, you're burning O2 at nearly double speed. The Rebreather normalizes this, making deep exploration viable. It's not flashy, but it's the reason you can reach those last fragments at 250m.

4 Optimal Collection Route

Follow this order to minimize backtracking and maximize efficiency.

① Scan Fragments + Gather

Both fragments in very shallow wrecks (30-50m). While in Kelp Forest, harvest Creepvine Samples and Seed Cluster for Fiber Mesh and Silicone Rubber.

② Craft

All at Fabricator → Equip in mask slot
DEPTH O2 DRAIN REDUCED

5 ⚠ Gotcha Tips — Don't Waste Your Time

Read this BEFORE you start.

⚠ Won't help without High Capacity Tank

The Rebreather reduces depth-based drain but doesn't increase total O2. Without the High Capacity Tank, you still run out fast. Get the Tank FIRST, then this.

⚠ Creepvine Samples vs Seed Clusters

Fiber Mesh needs Creepvine SAMPLES (the green strands). Silicone Rubber needs Creepvine SEED CLUSTERS (the yellow glowing pods at the top). They're different — harvest both.

Don't leave empty-handed.

🎁 Kelp Forest harvest

While getting Creepvine: Collect Metal Salvage (4x Titanium), Stalker Teeth (save for later!), and scan all the unique Kelp Forest creatures.
