Some general injury and bleeding houserules: looking for feedback

[tfaal]

That's true. Here's my take on it:

Immediate collapse is always a tricky problem, because there aren't many reliable biological causes for it, but at the same time, it's the goal of most martial arts, and the end result of most combat in fiction. However, if we're being realistic, a cut to the arm is a fairly simple case. Excluding surrender, there are only a few factors that could cause a victim to topple over and stop fighting: pain, psychological "fainting", and blood loss. Of those, only blood loss will cause actual lasting unconsciousness. I figured that the Knockdown and Stunning roll from a major wound would be sufficient for pain and psychological collapse.
