I have calculated the weapon proficiency reduction due to armor weight for crossbows using the data provided by Gafferjack.
armor weight modified proficiency = base proficiency * (1 - 0.01 * effective armor weight)
and
effective armor weight = 3*head armor weight + body armor weight + leg armor weight + 2*hand armor weight - 7
As with the previous version, I would assume that effective armor weight values less than 0 would count as 0. The blue dots on the plot below are Gafferjack's data points and the black line shows the calculated values using the equations above.(click to show/hide)
search forums for waltf4's postsso if my weight is under 7.5 when it comes out of that calculation, it is fine?
