Yeah I think Mistborn is my favorite magic system in the cosmere books, allomancy and metalminds are just so cool.

I also really appreciate all the work Sanderson does in including just about everything he uses in his books. From talking with mental health professionals and those dealing with different issues for characters with depression, DID, autism, etc. to creating accurate portrayals of silk in a world without silkworms. He really does an amazing job building worlds and characters.
