Bone Shatter Jugg Overwhelm Physical Reduction - HELP ME!

Need some help please, I'm running a bone shatter juggernaut build using fourth vow/divine flesh, I've just started running some juiced up T16 maps, I can handle it okay, however at least once a map a random mob spawns with "overwhelm physical reduction" and kills me so quick/easy

is there any kind of counter to overwhelm physical reduction?
