Dunno off hand what that particular take down recurve bow’s draw weight is, especially since the actual weight on the fingers (well, toes) depends on how far drawn the bow is rather than its rated draw weight, but I can tell you that a 10 pound rated bow can launch an arrow over 150 yards. Don’t under estimate light draw weight bows just because hunters are obsessed with super powerful bows for long distances, flatter trajectories and clean kills. A light draw weight bow is still dangerous to bystanders if used in an unsafe manner.
An arrow is thin and pointy, so it takes little force to make it penetrate a human body. It might take a very “lucky” shot from a very light weight bow to the neck or other unprotected spot to be lethal, but pretty much any hit by an arrow is going to be injurious. The low amount of force of a kids’ starter bow, such as ten to thirty pounds, may not sound like much, but would you let someone strike you in the gut with, say, an ice pick using “only” ten pounds of force? I’d hope not. Same goes for being shot by Ms. Dossi’s bow.
Anyway, I should add that I thought her act was a good mix of skills and I think the cut of the costume worked well for her, though at times the dark outfit made her hard to see.
