2 hours ago, theBitterFig said:"When engaging" language means that Qi'ra wouldn't apply to bonus attacks. You could fire one Cluster Missile, but not the second, which would be more absurd than this already is. Qi'ra's language is as good as it could be to be both brief and clear.
Yes you would be able to fire the second, it trigger during your attack, and you are still the engaged ship. But yes it would not work during Dengar bonus attack, but that is ok, because anyway they want to make sure Jumpmaster are never played again.
