I've been trying to determine the math behind armor rating.  In some games it's a straight damage reduction, but the numbers in this don't support that.  In some it's a percentage thing, but again the numbers don't really support that.  Someone on another board suggested that it might be a relative health multiplier, and that's possible.  That would mean that 100 health with 100 armor would mean that you'd take 50% damage from physical attacks.
Does anyone have any idea how this system works?  Thanks in advance!
