How does an astral dreadnought eat astral travelers?

He's supposed to eat them by fluff.

But his only eye projects an antimagic cone. Wouldn't they wink out whenever he faces them?

No?


All magical, spell-like, and supernatural effects within the cone are suppressed, except for those that brought the subjects to the Astral Plane in the first place (the astral projection spell, for example). Those effects are locked in place while the subjects are in the cone and cannot be
dismissed, trapping the subjects on the Astral Plane while under its effect.

A selective antimagic cone? Now that's a weird one. I was undereducated.
