Hey Guys, Just was re-reading Warbreaker and came across a couple questions. If its a guaranteed thing that when you transfer breath you are required to give all your breath away at once and cannot separate it (like give one at a time), why cant you just put some breath into something that doesn't need a ton of breath to awaken, and then give your remaining breath to someone and retrieve the breath from whatever you awakened. That way you could essentially separate the breath. Working like this with another person, separation of breath would be relatively easy. My second question was that is each persons breath unique? Like if you have your breath, is it distinguishable if you swapped it with a different one?
