Subnautica 2 Lithium

Subnautica 2 Guide

When to start dedicated lithium runs and how to avoid risky dead trips.

Quick answer

Lithium is an early-mid progression gate. Current route guides place early access around The Great Jaw and later safer loops in hotter/deeper cave routes once you unlock better survival tools.

Route cards

Great Jaw early route

The first lithium loop is a fast in-and-out run at The Great Jaw.

Do not overcommit inside the maw.
Grab what you need and leave.
Keep the route short enough to reset safely.

Hot cave follow-up

Once Heat Tolerance unlocks, shift to safer repeatable hot cave loops.

Use the new route for repeat farming.
Favor consistency over one large risky run.
Combine lithium with other deep-route goals.

Spend order

Lithium should go to depth and survival upgrades first.

Hold back a reserve for the next blocker.
Do not burn it on convenience crafts.
Treat each haul as a future progress buffer.

Where to Find It

Start with short Great Jaw extraction runs and avoid overextending inside the maw.
Use known silver/lead landmarks as return anchors before committing deeper dives.
After heat-tolerance progression, pivot to hotter cave loops for more repeatable lithium farming.

How to Use It

Save lithium for unlock-critical upgrades before optional expansions.
Synchronize lithium spending with depth-module and mobility goals.
Keep a buffer so one failed deep run does not halt all crafting.

FAQ

Should I hunt lithium immediately?

Only if your next hard blocker requires it; otherwise stabilize safer progression tools first.

What preparation matters most?

Reliable oxygen plan, repair capability, and known return route.

Why do lithium runs fail often?

Most failures come from overextending depth before tool setup is ready.
