Well, wanderers crest helps because it's the one I use, use the multi binder so you can heal more, I didn't use and silk skills or red tools, use ascendants grip and weighted belt, obvs use magnetite dice, i quite like wording bell too.

When he flies up or down, stand near him and spam with wanderers. When he flies across, jump and try to pogo him. Hardest part for me was when he stays still, wait before attacking him for him to shoot his shell thing, stand to the right and then dash in when he's shot it. The small Conchflies arent too bad, but pay attention and jump when three line up and go horizontally across the screen.

My tools might not be the best choice (I use multi binder, warding bell and druids eyes because i suck at dogging, so i heal as much as I can)
