Cold stops you before useful deposits
Warmth is the direct upgrade candidate. Improve it, then repeat a similar climb.
Mine a Mountain Warmth guide
Warmth is useful when cold—not bag space or mining speed—ends the climb. Use a repeatable run to prove that before spending.
How to stop freezing
Turn back while you can protect the haul, sell the crystals, and put the next upgrade into Warmth if cold was the first constraint. The official game description confirms cold near the top and lists Warmth as an upgrade, but it does not publish a universal temperature or timer threshold.
Diagnosis
Was Warmth actually the problem?
Your backpack fills first
Buy capacity instead. Extra warmth will not prevent the forced sell trip.
Mining each deposit is slow
Pickaxe is the likely bottleneck; warmth only extends a route you are already completing slowly.
The mountain just rotated
Scout first. A different path may reach useful crystals without demanding the same climb.
Safe climb
Use a turnaround rule
- 1. Decide whether the goal is cash or altitude.
- 2. Watch cold and backpack space together.
- 3. Turn back when the remaining margin no longer covers the return route.
- 4. Sell, record what ended the run, and change only that upgrade track.
Exact cold thresholds may vary, so this guide deliberately avoids fabricated numbers.
