Yea, that was an addition I liked. I've got no horse in the race as to what the stuff on the backside of the chest plate is, but it's neat to see. it could even be a system to help shunt off energy from blasts/hits. almost like modern body armor working well because it's combined materials and purpose. the beskar is strong enough to keep you from being outright killed by something, and disperse it well enough, that the network on the backside can collect and shunt off the disbursed kinetic and heat energy. That being "proposed", I don't need or expect an answer. I enjoythe fact that star wars is science-
fantasy, and the tech only needs surface level explanation, because it's really just a placeholder for magic/a mechanism for moving the story forward. "why is his armor work better?" "it's made of a special metal" "how does that special metal work?" "it works by being
better..."
probably just a material to hold everything in place until an actual armor could mess with it.
-odds of them issuing out "beskar infused JB weld" to fix damage with?
Low - they'd rather make better gear from it.
-odds of them issuing out
actual JB weld?
pretty good
Though I suspect, in the grand scheme of things, we've gotten into the realm of "they showed it a certain way for story telling purposes" rather than any deep intended canonical purpose. Keep in mind, so MUCH of the cannon we subscribe to is just someone else coming up with a way to explain things that were done for story telling purposes in the original films.
