Eh, it's a tough call. If you follow the 'hustle' rules, someone hustling for 72 hours would take 2^72 - 2 points of nonlethal damage (2^71 + 2^70.... + 2^1), but of course they'd probably pass out somewhere between hour 4 and hour 10, depending on class and level.shilsen said:Just for the record, warforged are not immune to nonlethal damage. Henry's story is a cool one, but by the RAW, a warforged can't pull it off.
On the other hand, the rules for 'hustle' come in to play for a character that hustles more than one hour 'between sleep cycles'. Warforged don't sleep, and they don't even have a recuperative phase comparable to sleep (the way, say, elves do). Thus, I could definitely see the argument that, lacking sleep cycles, a warforged can't do anything 'between sleep cycles' and that the hustle rules don't apply to it.
