Fortitude

Using Fortitude you push yourself past your normal limits, often involving avoiding fatigue or exhaustion. All of the options listed on the table make the character fatigued if they fail their first check against this, exhausted on a second failed check, and finally unconscious on a third and final failed check.

This uses Endurance as an ability. Armor Penalty reduces these checks.

The following are expanded uses for characters. These checks are considerably more difficult, and usually only able to be completed by the most dedicated practitioners.
