After finishing Bands of Mourning, I was confused as to the abilities granted by the bands. It makes sense to me that feruchemically charged metalminds with stored investiture would allow an individual to access and use the power in that metalmind because metalminds are how feruchemy is naturally used. I don't recall any explanation as to how allomantic ability could be stored in a metalmind.
Once the allomantic ability is stored, why is it that the ability is accessed via tapping a metalmind instead of burning a metal?
Also, this is my first post. Hello everyone!
