Robin's magic tugs on Phalanx's body, and some other magic tugs back. It isn't a dramatic reaction (it's barely noticeable, really) and it obeys Robin's wishes after just that little bit of coaxing, but it's enough to tell for sure that this creature is held together, in every unnatural fiber, by magic.

It doesn't glow; the spirits are more active and prevalent than the magic itself is. Whatever is there now is likely the result of what was first put in place at the creature's creation and then left as an inert structure to keep everything running afterward. Living by technicality, but not as any natural creature was ever meant to be.

And Phalanx doesn't notice. They're busy watching after Vincent.
