Water Secretion
PassiveSlowly fills a water packet by filtering fresh water from the sea
Always active while equipped·Early Access: equip 1 Active (default Shift on PC) and 1 Passive at a time.
How to unlock
Scan Water Slug with the Bio Scanner.
Bio Scanner required
Most BioMods require the Bio Scanner attachment (green glow while aiming). Parts are found in the late-game zone; craft at a Modification Station. Standard Scanner scans do not unlock BioMods—you must re-scan donors with the Bio Scanner.
Where to scan
Extremely common—starter shallows right outside your base and many late-game seafloors.
In-game effect
Every 3 minutes adds a Filtered Water Packet (+30 water) to your inventory. Stack caps at 30.
Tips
Easiest hydration passive to unlock. Clear stacks before cap to avoid wasted ticks.
