Warmth and Freezing Guide

Warmth is a survival budget. You improve it by lowering heat loss, raising heat power or heat capacity, and shortening the time spent digging through bad routes.

Heat Math

Source	Effect	Key values
Heating	Core passive warmth upgrade.	Heat Loss Rate 7 -> 1 Heat Recovery Rate 15 -> 50
Heater Sled	Raises carried heat capacity for longer routes.	Heat Capacity 50 -> 200
Hot Tea	Temporary heat generation and dig-power boost.	Cooldown 30 Heat Generation 4 -> 20 Dig Power Multiplier 1.2 -> 2 Usage Time 10 -> 20
Gloves	Digging boost with heat-loss mitigation.	Digging Speed Boost 15 -> 35 Heat Loss 85 -> 65

Best Warmth Tools

Tool	Role	Key values
Heating	Best passive answer to cold pressure.	Heat Loss Rate 7 -> 1 Heat Recovery Rate 15 -> 50
Heater Sled	Best route extender when objectives are far apart.	Heat Capacity 50 -> 200
Hot Tea	Best burst option for digging while recovering heat.	Cooldown 30 Heat Generation 4 -> 20 Dig Power Multiplier 1.2 -> 2
Cozy Bubble	Best emergency cooldown-style warmth tool.	Cooldown Time 300 -> 120
