Yeah that's what I was talking about.

Just seems kind of odd to me as it seemed like using Auracite was a bad idea given what happens to other characters using it, and their spirits aid us against Ultima without having to transform by destroying the summoned Demi lucavi things and then making the barrier. So it just left me feeling like it was just done for the sake of having cool boss models rather than making sense but maybe I'm over thinking it.
