The peak of luminmechs army, the God of Death, Execour. There's a golden version called "Gildina Execour" after step 10, but you can also encounter Varuna or Shiva, or both if you go final step (step 30). Good luck beating them at lvl 100 :p Enjoy the music!! Amongst the best tbh ^^
It was harder than i though to link properly what i've put as 2nd part to the 1st, kinda ironic when it's supposed to be its follow up lol. The 3rd and final part only happens when Execour goes into "Offense mode" which you trigger by breaking his back crystal.
PS : Now i'm pretty much done with EP6 musics until the 2 last story chapters and final raid boss, so with updates being postponed atm, there's not gonna be new post until June i guess lol
