I have both a hat and boots that have the "increase base dodge" ability (specifically the jalon valley chilote and liberi's corsair scarpones). Upon wearing one, I receive an additional 5 dodge total. Upon wearing both, I only receive an additional 4 dodge total. Was it meant to punish you for having multiple increase base dodge abilities at the same time or was it meant to operate by adding 4 to the previous 5 and get 9 but was just mixed up with the other dodge abilities?

This happens with all "increase base [insert stat here]". Each rank of it adds less. Here's a little list: 1st: +5 2nd: +4 3rd: +3 4th: +2 5th: +1 It may seem like more ranks aren't worth it but if you have all it totals up to 15 which is a pretty decent boost (in my opinion).

No, what I meant is that the total does NOT add the previous ranks to the current rank. In your situation, if I had rank 5 then I would get +1 instead of +15.
