So far I am loving Endwalker way more than Shadowbringers (SPOILERS UP TO A POINT)

[ProstheticSoul]

I HAVE NOT GONE PAST THE BROKEN GLASS CAMP ARC. NO SPOILERS ALLOWED BEYOND THAT POINT. EVER. THANK YOU

So far there's no time travel, no metaphysics, no world-hopping, nothing. This is like a breath of fresh air! The story is actually comprehensible! Joy of joys! Blonde Sephiroth is back, and there is a clear, defined enemy along with a clear, defined path toward said enemy. Urianger's presence is so diminished thus far that I can't help but cry tears of unbridled euphoria! There is no malarkey revolving out-body-experiences, no tripe surrounding Minfilia and her 18 lives (twice the amount of Y'shtola I might add considering she's the author's pet) and no WoL talking to some weird ghost of Marauder past/present/future.

However, I fear there is one massive plot hole that has besmirched whatever shred of respect I had left for the writers. It concerns the radios found in Empire Land™. Y'shtola explained that the reason the survivors we just stumbled across were immune to the tempering was because the radios were made out of the same material as the talismans we acquired from Elephant Lady.

I'm sorry, what?

This makes absolutely zero sense. The Talismans were constructed out of dragon scales. So unless I'm missing something here Square-Enix was just super lazy in concocting up this egregiously convenient contrivance. Can someone correct me? Please? I kind of want to be wrong in this case. Because this is ridiculous.
