This is a relatively small satori, but it’s what comes to mind. A previous iteration of Runequest used a system that had Masteries included in the system. It might have been called Glorantha at the time? Crucible of the Hero Wars?

Anyway, this system extended the rules for skills and stats to objects. So I could have the Murder Ducks skill at 17 (or whatever), but I could also have a Magical Sword item that had a 17 rating. Instead of rolling something that reflected my character’s attributes or skills, I could “roll the item” and influence play that way.

I’d never seen that before. I think I read somewhere that it would be like Han Solo having a “Millennium Falcon skill” and that stuck with me.
