I don't know how to research this. Maybe somebody has an idea? Maybe this is a case of whatever the author goes with works.
Idea was to have Character A break Character B's hand by smashing it with the end of an electrostaff. Looking at pictures of the type of electrostaff, I'm not sure if that works because of the way the ends are. Can't think of anything real life to google to see what sort of damage Character B would incur. I need Character B to not have use of their hand until they get medical treatment.
