Sorry, but I have to do this. Your title is wrong it should be "How much cR would it take to get Emile's right and left shoulder, and Commando Helmet?" How much cR do you have? What rank are you? And how much are the shoulders?
Why did you answer this question? You explained nothing. To have these parts you need to have about 500,000 cR and I'm not sure, but you have to be a General (or Brigadier), so it takes some time.
