So last night I got and finished The Alloy of Law, and I saw something in the Ars Arcanum that I wondered about. I didn't get what the Feruchemical properties of Cadmium, bendalloy, chromium, nicrosil, aliminum, and duralumin.
Cadmium: what does it mean to store "Breath"?
Bendalloy: does it just store energy and give it back later to any task?
Chromium: Does it make you lucky?
Nicrosil: What does it mean to store "Investiture"?
Aluminum: How do you store Identity?
Duralumiinum: How do you store Connection and what does that mean?
If anyone could answer these questions, it would be greatly appreciated.
