IMO they need some more explanation around it next season. So the mithril alone was too small to help but make it even smaller and put it in rings and it has the power to save all the elves in a city.
True. I always guessed it as mithril + the elven stones added to the rings have their own properties+ the user's life-force/will all affect the scope of what the rings can do or the range affected/maintained by them.
I'm no Tolkien expert but that's what makes sense.
