shadow mantle,
even if you're not using terra staff, for instance locking in a Mythic for TP, you should have np reaching capped pdt.
umbra is old hat
If trying to hold TP, how do you cap PDT without some pdt back?

that's not 50%, even swapping a cap pdt dark ring for the adoulin reward wouldn't cap.
With umbra you could swap out a couple pieces to make room for some Converts damage to MP, and more defense and cap pdt. just don't see how to cap without something in that slot with pdt or ability to swap weapon/sub.
