Within minutes of starting Arcanum, I ran into having to wonder what the difference is between total ac and total defense. Is total ac just irrelevant, and the real number of your not-getting-hit-defense is total defense?
I am rather shocked and frustrated that I cannot find this answer anywhere. I have searched forums, google, and the manual. It seems like such a major question, and yet nobody seems to have it or answer it.
Maybe it is just obvious to everybody but me. Can anybody clue me in?
