Ended up having to use an elixir for Ragnarok. Got down to about 1/4th HP. Though most of it seems to be more or less luck for me, was being extremely reliant on dizzy. When my attempts to reapply failed (2 dizzy skill himes), I wiped pretty fast after. Either eating a 4k raging overdrive or a single 7k regular overdrive... I have only regen healers though so that was one of my biggest issue after taking a raging overdrive hit and regular overdrive can pretty much 1shot my himes which is just as dangerous. I probably won't bother using elixirs anymore, just for the first clear.
