I see a lot of people saying that 'per encounter' abilities recharge with a moment of down time. But what if there is no down time, no time to 'catch your breath'. I'm thinking this:
The party enters combat fights for a 3 to 4 rounds using their 'per encounter' abilities. They are extremely unlucky and have to retreat and are no longer in sight of their opponents. They run away from their combat. While they are running back the way they came; without stopping, no rest, no breather, they run into another group of baddies and enter combat with these guys. While that combat is going on the group they were running from catchs up and joins in the fun of combating the party. Having had no time to rest, are the party's 'per encounter' abilities reset with the second group of baddies? Do they reset when the first group shows up for the fun because that first group has to roll initiative when they enter this combat? Is this two encounters? Three? Or just one long encounter?
How about that first group, do their abilities reset? They might have taken a moment to 'rest' before persuing the party.
I will admit I do not have Bo9S nor SWSE.
