==Fortitude==
Fortitude is the ability that measures a character’s
endurance, resistance, and healing. While a normal
human can never regrow a lost arm, someone with
moderate class in Fortitude can eventually recover
the arm over the course of years, and a character with
exceptional class regains any lost limb in mere weeks.

The Importance of Fortitude is that it determines
the magnitude and duration of powers. Those with the
blood of the gods in their veins can fight much longer
than mortals, survive horrific injuries, or even recover
from wounds that would normally be fatal. Fortitude
also regulates how long a character can keep going
before collapsing from exhaustion. In many situations,
a character with superior Fortitude has a significant
advantage if matched against someone of similar Might.

Fortitude’s Benefits: A character with a high class
in Fortitude can continue to fight, run, and generally
engage in strenuous activity for hours or days on end.
He requires less sleep and less recovery time from
wounds or exhaustion. Immortals can also regenerate
from injuries or even regrow lost limbs; a character with
a high class in Fortitude can accomplish this healing
faster than others, even without shapeshifting powers.
