Do it with ragnarok, now THAT would be a feat
Lol, I've made that mistake before. I used to think Herc's def down keeps missing. It's especially hard to tell in the video 'cos you have only one debuff, otherwise you can normally see the debuff order reshuffle when Herc's def down lands and overwrites the existing one.That would've been a lot smoother if I had remembered that Hraes + Herc Axe is not -45% Def.
EDIT:
Btw, just purely out of curiosity, does soul solo count as completing with R or lower only?
