The short answer
Collect a Water Slug and craft Water at the Fabricator for a reported 40 water. Once you have a Processor, 3 Fibrous Pulp provide an alternative water recipe. Refill before leaving shelter.
Before you start
- Leave free inventory space to collect slugs.
- The raw-slug emergency option requires Digestion; prepared drinking water is the normal supply.
Make your first water near the Lifepod
Adaptive Measures fixed an uncollectable Water Slug beneath overlapping Feather Kelp in the Lifepod cave. Do not build your supply plan around an old pickup bug or a guaranteed respawn timer.
- Search the nearby seabed for Water Slugs; keep the Lifepod or your return landmark in view.
- Pick up a slug, return to the Fabricator, and select Water under Sustenance.
- Drink as needed, then prepare carried water for the return leg of your next trip.
Choose a water recipe by available ingredients
Keep enough Pulp for food and Fiber before processing the remainder. If you already grow Macaron Sponge, its Pulp harvest can support all three supply chains.
| Option | Station and input | Use |
|---|---|---|
| Water | Fabricator: 1 Water Slug | Reported +40 water; nearby collection route. |
| Water from pulp | Processor: 3 Fibrous Pulp | An alternative when harvested plants are easier to replenish. |
| Isotonic Water | Fabricator: 1 Flash Slug + 1 Salt | GameWith reports +55 water; uses Flash Slugs, not ordinary Water Slugs. |
At zero water, treat the cause of health loss
Dehydration drains health when the water meter empties. Drink and retreat to resupply; a healing item does not replace the missing water.
After Digestion, a raw Water Slug can provide a small emergency water gain at the cost of food. Check both meters before using it. Cooked or crafted supplies are the better planned option.
Supply crates can contain prepared water. Carry what you find, but do not assume an opened crate will refill after saving and loading.
Use Biomods as support for carried water
Equip through the Biolab and observe the output on your current build before reducing carried supplies. These effects do not establish an unlimited safe dive time.
Buddy System Hotfix 1 restricts Water Slug breath markers to slugs in the world. An inventory slug is not a portable breath-marker source.
| Biomod | Bioscan target | Role |
|---|---|---|
| Water Retention | Coral Crab | Increases water gained from sources. |
| Water Secretion | Water Slug | Gradually produces a water packet. |
