Does anyone happen to know the formula for calculating PF for armor and shield equipped? I've always thought it was as simple as adding stats of the shield to stats of the armor, i. e. if I wear a set of armor with 500 vs Slash and equip a shield with 200 vs Slash, I get a total of 700 vs. Slash. I did some tests recently, and the 'Max Vs' stat works that way indeed. But I got some weird results for PF, which makes me think it's different. Any thoughts?
