Mobility gear directly controls whether deep-route catches can be finished safely and returned to sell points without reset risk.
Mobility Stat Priorities
- Oxygen (o2): determines how long you can stay active before forced retreat.
- Max Depth (m): hard gate for zone access and deep farming routes.
- Speed (m/s): lowers travel downtime and danger exposure between waypoints.
- Weight (kg): heavier tubes usually trade maneuver feel for stronger survival stats.

Upgrade Route Planning
- Start with low-cost oxygen gains first (
Old -> Normal -> Fire) before buying lateral tools. - Take the first speed bump at Pufferfish Tube to reduce dead travel time.
- Prioritize
Boat,Rukiry, andOxywhen your farming route begins to fail depth checks. - Switch to
Lost SpiritorRuinedfor high-risk deep loops where retreat margins are thin. - Add
Radarearly for fish filtering andMinimaponce chest runs become part of your cash cycle.
Practical Loadout Rules
- If your route fails by timer, buy oxygen first.
- If your route fails by pathing risk, buy speed first.
- If your route fails by access lock, buy depth first.
- Re-check your travel loop after each tube upgrade so your route scales with your new movement window.
