Final Boss Fight With No Skill & Debuff Challenge | Knight of Erin

In this challenge, I used simple ATK+DEF build with S rank ATK so that the video isn't 3x longer, and A rank DEF because S rank is too easy, one of that you can easily procs Perfect Guard even on good. The gameplay loop here are Basic ATK, also charging the green bar to around like 90, MUST Perfect Guard, after that I used the Super Art (still counted as Basic ATK, sort of like a Charge ATK). and repeat. This was actually my third tries, here I even messed up the Perfect Guard once, also I realized after the video that you can do Basic ATK and then Super Art in one motion before the blue bar empty. Oh well, it's still pretty challenging I would say.
