I'm kinda cheating here. My Joan's Voice of the God (cut damage taken by 40%), Trial by Jury ( -atk 20% A frame) with Sniper Shot Ex ( -atk 20% B frame) along with Sol's Caldo Luce ( -atk 20% C frame) combo did cut the damage by a lot. A Lvl49 Ultimate Pride's raging w/o buff overdrive was doing sub-2k damage on each of my characters. And even if she buffed up through that non-raging overdrive, Sol's Afrodull can remove that.
