Something that you only get after a 5 minute rest.
What's an example of this, preferably from the XP characters? This is the first I've heard of this, and I've been reading this forum for a while now.
As to my point, an encounter is presumed to take five minutes. So if you've finished an encounter, I can't imagine too many circumstances wherein you can't take a brief rest ... nor, given the healing surge mechanics, too many circumstances in which you wouldn't
need to do so. So even if "per rest" abilities exist, they're not going to be lacking, and thus they're irrelevant in terms of "running on fumes."
Another thing I find interesting is the claim that an encounter without "per day" powers is "very harrowing" and (presumably) genuinely risky. No offense, but for the vast majority of encounters, I don't believe that. 4E is designed for multiple encounters in succession, and only in one of those encounters is any given "per day" power available. Making every other encounter genuinely risky is
extraordinarily poor game design. If you don't want TPKs on a regular basis, you don't design for "fair fights."
Some risk, sure, but "very harrowing"? I doubt it.
