We all know there is something called weapon durability, but I’m not talking about that. I’m talking about when certain demons are stronger than you in levels, If you try to block some of their attacks your nichirin blade will shatter. But still about 30% of it stays on there. It should decrease your damage but activate something called slayers resolve, Which lets you continuously use any move on the demon. NPC

i think this (if added) should only be implemented for the main game and PvE, and not for gamemodes

so basically only npcs can break your katana, and broken katanas do not transfer over to gamemodes
