A shot to the neck could break the neck which can although might not make death very fast. A shot to the neck will likely make the wounded unable to breathe. The wounded would then pass out in 30 seconds to about a minute. Once the wounded is out cold, actual death would come from suffocation or bleeding. For a lot of blood to come out of the mouth the arrow might need to be removed from the neck. This would likely speed up death.
So basically it depends. Which works fine for me as it gives me options. I'm a few chapters away from this scene still, but I'm curious now what the comments will be!
Thanks for this!!!
