Fatigue / Exhaustion due to lack of sleep


Rules Questions

I arrived at a situation in an AP where the group will need to stay awake for two full days.

The AP itself mentions that characters will get exhausted and different situations which may arise due to that ( and due to heat exposure ), but there don't seem to be rules in the Pathfinder core book as to when characters get fatigued and later exhausted due to lack of sleep.

Are there any rules hidden in the book I haven't found or are they simply missing? In case they are missing, what would be the best way to handle the situation. The characters are in a stressful position which requires regular strength checks, but are not doing a forced march, so those rules don't seem to apply.


There's a lot of these rules in the movement section.

A character can walk for 8 hours without out becoming fatigued. That's 8 hours net, not just in one stretch. Once you walk your limit, you are fatigued until you rest.

You can only hustle for one hour. A hustle is anytime you take both a standard and move action in the same round. So, most combat.

If they are exerting themselves constantly, making checks every round, that would work out to a hustle. If they only have to make checks once an hour, or so, is there something stopping them from sleeping between checks?
If they just have to stay awake to watch something, that's a lot easier because it doesn't require any exertion between checks.


1 person marked this as a favorite.

First attempt didnt post, here goes shortened post #2

A character who walks for more than 8 hours rolls a con check DC10 +1 per hour after the first check. Fail once = fatigued, fail again = exhausted.
1 hour of rest cures exhausted, 8 uninterrupted cures fatigued. As far as staying awake 2 days in a row, I'm not sure ><. Eagerly awaiting an answer myself, and shamelessly bump for one. :)

I have used the exertion rules for continuing to walk, but start after 24 hours. So DC10 at 24 hours, DC11 at 25, etc. For every hour rested over 8 the night before, I add +1 hour to the time they can stay awake... sleep for 12 hours, awake for 28 before checks.


There aren't rules for fatigue/exhaustion due to lack of sleep. If you poke around, there was a thread kicking around a few weeks ago on the very topic and potential solutions. Start here in Rules Questions and in House Rules.

The movement rules don't apply in this case, as I wrote in my original post. The characters will have to stay awake two entire days ( without warning ) and keep large objects from falling ( one for each character and with checks every several hours ).

I will check the threads of the last weeks, but using the search function, I didn't find any more recent thread than one from 2008. ^^


+1 Steve.

Also, Lesser Restoration will help them out.

Guys, I already said I don't think the movement rules apply. ^^

Damn, you stole my post. ^_^

At any rate, DarkMidget and I went through a lot of working with sleep deprivation, and I think we came up with a good system (even if we never really "finished" it.)

The adventure in question specifically says when the characters are fatigued due to lack of sleep, on page 52. It says:

Furthermore, once the PCs head into the second day, they are operating on no sleep and become fatigued.

So, the PCs are fatigued the entire second day.

Yeah, that makes sense. My concern is a bit that this becomes irrelevant quite easily due to Lesser Restoration. The adventure later on states the characters will also be exhausted at the end, so exhaustion onset should come faster than the fatigue onset. Man, I'd wish the writers would have gone into some more detail on this. :(

Well, of course. I'm a dark elf. We lie, we cheat, we steal posts!
