Expanding on pewter
Renewed interest in pewter after it was brought up the other day.
WoB like this one here (https://wob.coppermind.net/events/503/#e15782) imply more going on than just a simple physical boost. As with any metal, there's an instinctive use that works right away (blue lines from iron, hearing rhythm with bronze) and pewter's is physical so no one questions an already useful skill, but..
Let's say that it's more Intent related, where your mind enhances *any* physical aspect. Not just the desire to run, jump, punch, or take a hit. What if I want to push on something with exactly 100 Newtons? Can I limit my physicality? Pewter can let you ignore the cold, but can it enhance your heat? What would the resonance between pewter-a and brass-f look like?
It's all speculation, let me know if you've got a fun idea for any other combination or use
