Great chaos above help

At my wit's end with this one, any help would be greatly appreciated. 30 attempts in I did not get to Typhon even once. If vow of rivals is active I don't even attempt the run any more (Polyphemus with vow is a formidable challenge for whatever reason).

I've beaten the underworld on 32 and surface on 24 but never changing the vows and weapon got me into a rhythm. With this one I feel hopeless, everything is constantly changing. I absolutely do not have mastery of all the weapons and aspects...
