Once again, I am back with more theories and questions. So, if a feruchemist got a set of Plate, could he store whatever trait that metal allowed, or would the shard plate interfere or feed off it? Because Plate feeds off investiture and Metalminds are considered another type of investiture that can be fed on (Check Nightblood age, it mentions he could feed of it, and I have a feeling the same might go for Plate.) But can it feed on its own investiture, or this not considered its own investiture? Strange thing to consider, hmm?
