Those are amazing builds. Yet I think that it’s hard until you get to highest abyss floors and get high value gear. The only thing that helps me so far is hayabusa +izanami (for the 15% ccd) and also Horned turban kabuto which helps me when there is enemy reinforcements status. I’ll definitely go for kingetsu susano, too, but until I get stronger gear it’s not enough power for me. Just for me, of course, everyone has their own play style. :)

Please deep explain , what item u use for that crazy damage to bosses I don't understand about builds

What is the correct buff order and why?
