Tips for Godskin Duo with no sleeping pots?

I know you guys will say use sleeping pots, but here’s the thing, when I use stuff like that, I become a terrible player and die very quickly for some reason. Godrick rune activated? Embarrassing death. Ember in DS3? Embarr- you get it.

So do you guys have any tips for when fighting them without? I’m using cragblade starfist’s but it’s just not working. Blasphemous Blade spam from afar perhaps? Something else?
