Anything that hits physical can be parried and pop nutshot/riposte on DRK, and probably PLD. Off the top of my head: Double Rocket punch, Seph EX's tower tankbuster, Nidhogg landing. Basically if it hits you for physical damage you can parry/block it and potentially get something to proc off it. When Seph EX was relevent I used to pop DD+Awareness for Jumps to try and get reprisal off if I was OT.
