How to make lots of CR if your a non Gold member
first you have to beat the Campaign then you go to the mission lone wolf. Next set some skulls that you want on then the difficulty. In this mission you are suppose to die but if you fight them then you won't get capped on CR. I made 654 CR by doing that for about 7 minutes.
