If I remember correctly, Threaten is PDRate. I don't think mob def even affects damage too much to notice. When Threaten is up at zak, damage increases greatly compared to it not being up leading me to believe it is PDRate. As for Blast, I can't say seeing as I don't notice major damage changes randomly what with the fact that blast crits tend to be the same exact number.
