Re: OOC
Its a sliding point of alertness.
How quickly does a person go from 'asleep' to alert enough to pick up a sword and fight without penalties?
A combat round is six seconds.
While everyone in the area might hear her yell, if you're in a deep sleep, it might take a little bit of time for it to register for you to get to wakefulness.
That's why the DC rating for a sleeping character to 'wake' for no apparent reason was so high. You're going from a sound sleep to alert that something in the area isnt right. Does it happen in stories, sure all the time, so if the character has a really high perception stat, they might sense something is off.
If a thief was sneaking up on anyone, it would be an opposition of skill checks. The thiefs stealth vs the victims perception. If the victim was fast asleep, the thief might have a situational bonus of +10, again if they're in a field of crunchy leaves they may not and it might be reduced... to say +2 / +5, as you say.
There is ... normal conversation before combat. Brigitte was having a conversation with Maybelle and Victoria. While the character might hear the conversation and treat it simply as background noise and stay asleep.
So... let's say a favored relative is asleep on the couch during a family get together. People continue conversation in the background and he sleeps through it. A loud arguement breaks out. They may... or may not acknowledge it as background noise, if they dont and they stir to wake, how quickly does it take them to realize that two of his cousins have gotten into an arguement and are now wrestling in the livingroom a few feet from them. How quickly before they stir off the couuch to breakup the fight?
Brigitte is fully alert, and 'just' noticed something. She has half a round to act, per house rules.
How much time would be realistic for someone to go from a state of sleep to action without penalty would be fair?
The worse rolls to wake at the start were Gar and Rifnox at DC 28. This is during 'preparation'. Before combat is even started. If they roll and fail their surprise round save, the roll drops to 24.
They now get to roll again, during the 'surprise' phase. Presume they fail again, the roll drops to a 20. This is when the sound of combat might be expected to start.
It drops to a 16 at the first round, if they fail
It drops to a 12 at the second round, if they fail.
It drops to a 8 at the third round, if they fail...
Keep in mind, if they fail, but by a margin that would have passed without the ten penalty for being asleep, the difficulty rate drops twice as fast....
etc... etc... etc...
It's all boring math...
On the round that characters first 'notice' they're in combat they get a standard action (as opposed to a full one). There are no penalties involved, you simply have the action to use, and the following round is 'normal'.
It is possible... to go the dazed... exhausted... fatigued... status effects to simulate wakefulness but that just feels more complicated and requires the players all be aware of the differences between the three and how they're being applied. While it's all good and well to presume that everyone knows them, its been my experience (that when i occasionally use them) that it's not the case.
Rather than just go through the complicated process of establishing conditions for each individual characters state, and their improvement through it, or any penalty for being half awake, i just use the system i use.
If Brigitte 'YELLS', and you fail your check, while you heard it, you might have ignored it... if you didnt ignore it, you might be too 'dazed' or 'sleepy' or what not to act on the warning. Regardless... your combat status has not changed from prone and helpless to combat ready.
If fail your check, and you want to roleplay dazed wakefulness to her yell of warning. I can get behind that, but your character wont have an action (not even a free one), till they make the check.
If it makes you feel any better, the encounters are actually 'balanced' based on this system of waking up, so if it makes you feel any better the encounter 'monster' is a lower threat rating because a notable part of the party is asleep has been factored in.
