Sleep and sleep deprivation (spelling?)

[JanosAudrun]

I cant seem to find rules for what happens when you dont sleep. I recon it means fatigued for the next day, I think i remeber something like that from the ol' 3.0.

But where is it in Pathfinder anyone know? Constitution checks not to be fatigued? Does endurance help?

I came up on this cause i had my ranger stay up all night watching a enemy camp for movement and such. :)

The general consensus from both 3.0 and 3.5 was that you'd use a mechanic similar to the Forced March rules.

forced march:

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.

For spellcasting issues it is covered by the rules, Magic Chapter, Pag 218 and page 220.
Divine spellcasters don't need to rest, but you still need to meditate for 1 hour.

I know for spellcasting purposes, but I'm wondering for others. As in the situation i described above :)

You could use rules cause them to be fatigued if they stayed awake too long, followed by exhaustion. If they were fatigued and then continued to adventure, they might be come exhausted, etc. As far as how many hours to reach each state, that would be up to you :)

Fatigued: A fatigued character can neither run nor charge
and takes a –2 penalty to Strength and Dexterity. Doing
anything that would normally cause fatigue causes the
fatigued character to become exhausted. After 8 hours of
complete rest, fatigued characters are no longer
fatigued.

Exhausted: An exhausted character moves at half speed,
cannot run or charge, and takes a –6 penalty to Strength
and Dexterity. After 1 hour of complete rest, an exhausted
character becomes fatigued. A fatigued character becomes
exhausted by doing something else that would normally
cause fatigue.

There isn't a specific rule in the rulebook (not that I can find) to cover this situation.

However, what we do know:

Pathfinder Core Rules, Equipment, Armor wrote:

Sleeping in Armor: A character who sleeps in medium or

heavy armor is automatically fatigued the next day. He takes
a –2 penalty on Strength and Dexterity and can’t charge or
run. Sleeping in light armor does not cause fatigue.

So if sleeping in armor (which sounds like you at least try to get some sleep, but it's uncomfortable and not very restful) means you're fatigued the next day, then I think it's safe to assume that getting no sleep means you're fatigued too.

Sure, that's an extrapolation from the RAW, and not actually the RAW itself.

Yes, I know, it would be nice to have that rule in the book somewhere, so we don't have to read the equipment chapter to get an inkling of a barely-related rule that lets us take a guess at what happens if we get no sleep at night.
