I've found success with Parry heavy using Void. A 4* maxed, can usually take off 75% and then clean up with my Domino.
As a few posts have mentioned before there are a few one shot options, basically anyone who does large damage/no buffs from heavy attacks. I used my 5* CapIW for all of my paths and solod him every time using parry heavy repeat I'm trying the same tactic with r4 unduped cap iw but i still get degen even if i don't hit him when anti life is active. Am i missing something else?
