Motivated March (Feat)

Years of forcing your slaves and soldiers to march far beyond the limits of their endurance have made you an excellent taskmaster.

Benefit: When traveling overland, you and a number of allies equal to 10 times your character level reduce the amount of nonlethal damage taken as a result of a forced march by half. Creatures benefiting from this feat can delay the fatigued effect of a forced march for a number of hours equal to your Charisma modifier (minimum 1). A creature that delays this effect becomes exhausted instead of fatigued when the condition takes effect.
