Class and Level Geekery XVI - These Characters May Now Drive the Plot

[D.One]

You have Sabine listed as "immunity to fatigue" because she says she doesn't get tired. This isn't quite accurate. Demons don't need sleep because Outsiders just don't sleep, but they can still be affected by the Fatigue status effect if someone casts a spell to inflict it.

Maybe we can change from "Immune to Fatigue" to "Doesn't Get Tired", meaning she wouldn't get tired from normal effort, but would still be subject to magical fatigue attacks.

Besides sleep and food/water deprivations (and some weather effects), the "natural fatique" situation I could find was when the rules talk about overland movement:

Overland Movement

[...]

Hustle
A character can hustle for 1 hour without a problem. Hustling for a second hour in between sleep cycles deals 1 point of nonlethal damage, and each additional hour deals twice the damage taken during the previous hour of hustling. A character who takes any nonlethal damage from hustling becomes fatigued.

A fatigued character can’t run or charge and takes a penalty of –2 to Strength and Dexterity. Eliminating the nonlethal damage also eliminates the fatigue.

[...]

Forced March
In a day of normal walking, a character walks for 8 hours. The rest of the daylight time is spent making and breaking camp, resting, and eating.

A character can walk for more than 8 hours in a day by making a forced march. For each hour of marching beyond 8 hours, a Constitution check (DC 10, +2 per extra hour) is required. If the check fails, the character takes 1d6 points of nonlethal damage. A character who takes any nonlethal damage from a forced march becomes fatigued. Eliminating the nonlethal damage also eliminates the fatigue. It’s possible for a character to march into unconsciousness by pushing himself too hard.

Maybe she is immune to this kind of fatigue, or maybe she simply has a sufficiently high combination of CON modifier and Endurance feat so that she rarely misses the CON check to avoid fatigue.
