I was just thinking about how useful it would be to have a metal anything that only you could push or pull. I came up with a way ish but I'm pretty sure it wouldn't work plus it requires you to be a fullborn.
my idea was if you compounded your connection with a specific piece of metal would you maybe be the only one able to push it.
I don't think it would really work but I wanted your guys opinions and to see if yall had any ideas for a way to do this
