I have been thinking about different ways the multiple magic systems in the cosmere could work together and I'm having trouble with nicrosil Feruchemy. If one stores there magic abilities in nicrosil does that mean they lose their magical ability completely? Can you even store 100 percent of anything through feruchemy in the first place? Like if you stored 100 percent of your health in gold, would you not die from it? At first, I would think that you cannot store 100 percent, but then again identity seems to have to be stored all the way to make a unlocked metal mind. Also, if someone obtained an unlocked nicrosil metal mind, would they have access to that magical ability as long as they had the metal mind? Or would it run out of investiture after being tapped for awhile?
