Análisis a fondo que se corresponden con las preguntas de habilidad de la calculadora.

Primal Fire
Primitive fire by friction and percussion: materials, steps, calorie cost and what fails in wet jungle vs dry desert.

Safe Water
Find, collect and treat water with primitive and field methods; know what fails in desert vs swamp.

Primitive Shelter
Stop heat loss fast with debris huts, lean-tos and terrain-based shelters matched to your biome.

Wild Food
Prioritise calories and safety: foraging rules, fishing, and why most trapping fails beginners.

Field First Aid
Stop major bleeding, manage heat and cold, and decide when to stay put versus move.

Navigation & Signalling
Stay oriented, travel efficiently, and make yourself findable with signals that work.
Por terreno
Qué falla primero en cada bioma y qué métodos funcionan mejor.

Forest Survival
Temperate woods offer materials if you manage moisture: debris huts, bow drill sets, seeps and clear terrain handrails.

Jungle Survival
Moisture and insects dominate. Raise your sleep platform, favour bamboo fire methods, and treat every cut as an infection risk.

Desert Survival
Day heat and night cold both kill—water, shade and smart travel windows come first.

Mountain Survival
Weather and exposure rule the high country. Windbreaks, honest turnaround times and ridge handrails matter more than foraging.

Arctic / Cold Survival
Cold is the clock. Stay dry, dig into snow for windproof shelter, and never waste calories on doomed friction fire without fuel.

Coastal Survival
Tides and weather rule the shore. Camp above the high line, hunt fresh water inland, and signal where boats and planes can see you.
