Hypothermia
Fortitude

Fortitude is a measure of your resistance to the Weather, Torpidity, and Disease. A higher Fortitude increases your natural Hypothermic and Hyperthermic insulation, reduces rate of defecating near Tyrannosaurus Tyrannosaurus roar, and lessens the effects that you receive from Hypothermia Hypothermia and Burning Hyperthermia. It also gives you resistance to Torpidity Torpidity-increasing effects such as consumption of Narcotic Narcotic, hits from Tranquilizer Arrow Tranquilizer Arrow or Slingshot Slingshot, Scorpion stings and other Torpidity-inducing attacks from creatures. Each level point spent increases fortitude by 2.


Increasing[]

Each level point spent increases fortitude by 2. This in turn increases the hypothermal and hyperthermal insulation by 4.5. In the HUD you will see rounded down integers. Bear in mind to resist hypothermic effects at -5 °C(23 °F), hypothermal insulation of at least 200 is required - so you will not be able to resist all weather effects using fortitude alone without adding an obscene amount of points to the skill.

Utility[]

Each point spent on fortitude will increase your knock-out threshold by 1. This also reduces torpidity gain rate and increases torpidity drop rate.

A Human with 0 points in fortitude will be knocked-out once his torpidity reaches 50 points, a human with 1 point in fortitude requires 51 torpidity to fall unconscious and so on.

Fortitude also seems to reduce the chance of catching diseases like Mega Rabies and Swamp Fever. This is yet to be tested.

Notes[]

  • Various Armors will also increase (or decrease) your Hypothermic and Hyperthermic insulation.
  • Food dishes can be used to temporarily increase your resistance to extreme temperatures: Fria Curry Fria Curry gives Hypothermic insulation, and Calien Soup Calien Soup gives Hyperthermic insulation.
  • Inside a building insulation is increased by 112 Hypothermic and 56 Hyperthermic.
    • Staying inside a stone or metal building on Scorched Earth almost always results in overheating. Insulation is unlikely to resolve this problem.
  • While Fortitude reduces the Torpidity Torpidity gained from various damage sources, it does not decrease the damage you receive.
  • As of Patch 280.114 natural insulation from fortitude was increased by 8% and the knock-out threshold now increases with fortitude as well.
