Even with Starchild assassins, trying to mind duel your Monolith will be no easy task: Odds are your capitol will be clogged with researchers, and more likely than not, the Star Child will wind up attempting to mind duel somebody who isn't even an astral mage! This will more likely than not give it away that he's even trying this....

And in order for him to even begin to attempt this, he'd have to have seen your monolith at least once in the first place to even realize you HAVE this weakness. This would necessitate a battle, at your capitol, that your monolith participates in. Since the monolith will always be researching or casting a ritual inside of his castle, this should never happen unless people are storming your castle!
