when you brake them it gives u a free hit chance

i think they stun him then you can attack him

Im pretty sure when you break them not only does it stun him it also increases the damage he takes from you. I could be wrong though.

Of course, when I posted htis on IGN, I was called a loser, fag, moron, and every other name in the book, so now I propose this theory to MKO.
So you can use the Kamidogus to allow an attack opening on the Dragon King, right. Well, what if a secret hidden in the game was unlocked by getting the Kamidogus in a certain order before killing Onaga? Just a thought. Nothing more. I sure as hell won't be trying it.
