Re: (TFT) Killing Joe

Interesting stuff, although I wonder what is meant by: Arrowhead vs. Buff Leather 30J
Does that mean that the arrowhead penetrates the leather and has 30 J left over, or that the leather requires 30 J to be penetrated?
Without knowing the speed and mass of the arrow, it is tough to predict the amount of energy it carries. Also, what are the effects of the arrowhead shape and material?

Jay,
While I haven't checked the site too closely, it looks like this person has started some tables for various weapons and their attacks in physics 
terms.
