Oda is trying to duct tape the DF, but it still makes no sense. What Haki is he talking about?
Armament Haki makes no sense, because it's like a suit of armour. He is not attacking them. Law has used Shambles to help people.
Conqueror's makes no sense, because it has nothing to do with will power.
Oda's lame excuse for everything now is "Haki" without even clarifying anything. Shambles in reality has nothing to do with Haki.
