Well then... This is good to know in its own way. The Armiger has always been something unique for the royal family, after all. That it can be replicated in a manner like this is something he should know, as Noctis's retainer. And it's good to learn this from Noct's friend (and now lover), who can at least be slightly more trusted - especially if he's trusted enough to use the Armiger on its own.

Ignis's thoughts are knocked out from place when Prompto speaks up again, and he blinks up over at the blond. "Oh, I would like to know much more," he confirms. "However, one must start somewhere. You've already given me a great deal of information as it is."

Also, this is really probably one of the better ways to work off that caffeine energy.

"So it looks as though Noctis has no problems with the Armiger."
