How to Light a Torch and Boil Water in Casualties: Unknown

Light first

A survival guide for this game covers eating, sleeping, lighting a torch and boiling water as one cluster of early tasks, which is a fair reflection of how they depend on each other. The crafting and item indexes list a torch, a firestarter and a lighter among the light sources, and the survival guide notes that better light sources come from crates, traders and crafting. Do not spend your only ignition source on a recipe you do not need.

When you cannot start a fire

A widely viewed tips recording points out that if you have no means to start a fire, working out via the bottom right of the health menu is an alternative way to warm up. A separate guide recommends boiling groundwater before you drink it, so keep fire and water planning together rather than treating them as unrelated chores. The rope and tools page covers the campfire-adjacent crafting chains and item condition gates.

Clean water

The crafting tutorial's later clean-water task uses a canteen to collect groundwater and a campfire to boil it. The crafting guide stresses that collecting liquid and purifying it are separate steps: making the canteen alone does not turn groundwater into clean water. The recipe index also lists clean water and campfire as distinct entries, which is a useful reminder that the container is not the treatment.

Heat and over-hydration

A tips recording notes that water and juice can be drunk in the desert to cool down. It also describes the slaked moodle that appears after eating too much water-bearing geo fruit, and says it is manageable as long as you stop when you see it. So water is both a temperature tool and a resource with an upper bound.

Build caveats

These notes combine a survival guide written for demo 7.0.1, a recipe index for a different version and machine-generated video captions. Exact fuel amounts, torch durations and recipe unlocks are not stated here because the sources disagree on which build they describe. Check the crafting screen in your own game.
