Perfect chapter, which is very rare for fairytail. I think the 12 spriggan have some sort technology to amplify there magic power... Maybe it's something similar to hades heart on his ship. I said this once before now I'm more certain of it natsu's arms since the time skip have been bandaged in every chapter.. I think he is slowly getting dragon scales or turning into end after coming into contact with the book of end. We know that igneel was slowly helping him develop anti-bodies so he doesn't turn into a dragon but what if the side effects of that are natsu's skin turning into dragon scales. If it's end, then probably he is getting a demon mark similar to the one gray has but he cannot control it from spreading.
