Silent salt cookie

You are just walking through the hall of old castle then something attacks you then you notice that it’s silent salt cookie he normally does not attack you, don’t know why, but you defend yourself and knock off his helmet with a very heavy attack as he’s slowly stands up. You know this his eyes are different color, the pure white, the only one with somewhat similar to pure white is mystic flour cookie so you prayed with him to not attack you but he doesn’t say anything and then still attacks you what do you do next
