I recently done the mch quest line and idk how the the baroness was able to usev"blood of the dragon" then turn back into an elezen in the proceeding cs if this is meant to be a specific spell glamour then it has a very bad name giving the context of ishgardian blood and this isn't only time it happens back in ARR the fake inquisitor you fight also does this turns into a dragon then following cs back to normal.
Whereas when searching for ice heart and we reenter the amphitheatre the ones that transformed stay transformed afterwards it's inconsistent but if there is any explanation for it I will gladly take it as my head is baffled by this
