Pdt Axex2 - 20%
mini expansion hat - 10%
AF3+1/2 legs and Stout Servant job trait - 7-8%ish
that with DG gives the 88% pdt. If you use a minor pdt atma along with DG you get 98%. I currently use RR/DG/Heavens for this setup. I tried out Tremors since its pdt and mdt but the minor on it is not 10%, maybe 5% to both pdt/mdt. I took more damage with tremors than heavens.
Now once you do that and add in the shepherd's chain - 2% you should have 100% pdt. I haven't got that chain yet myself but I assume it would top off the pdt.
