Stamina
Stamina is used whenever most combat maneuvers are activated. The maximum stamina a character has determines how often that character can use maneuvers and if a character overexerts themselves, they can no longer use any maneuvers for a period of ten minutes and suffer a -10 penalty to their attack strength.
Maximum Stamina
Maximum stamina is determined as follows:
CON + ((STR + AGI + DIS)/3) + (Physical Fitness skill bonus / 3) = Maximum Stamina
All fractions from the above formula are dropped.
Stamina Recovery
Stamina recovery is determined primarily by the character's constitution statistic, with the regeneration rate ranging from 20% to 30% of the character's maximum stamina per minute (thus, strength, agility, discipline, and Physical Fitness training also have a minor affect on stamina recovery due to their influence on a character's maximum stamina). There is a 5% bonus to stamina recovery if the character is sitting, kneeling, or prone, but only if the character is also not carrying a weapon in his or her right hand. Nodes have no effect on stamina recovery.
