PDR lowers while moving?

I cant seem to find whats causing it. My armor remains the same but my Physical damage reduction value lowers from 82% to 73% when i start moving. I have checked my items and Skill tree but there's nothing that says it lowers pdr while moving..... can anyone tell me why this is happening?

I got it, its the pantheon that adds PDR while you are stationary. Sorry for the post ;D

Yeah there's quite a bit of other mods that do this as well based on moving/ not moving.

Careful with PDR.....it also changes based on the incoming hit damage. So while you might have 82% in one encounter, you may have significantly less in another.

Armour and the tooltip is funny that way.
