I ionised Guri the other day , and was like you don't have Focus on your action bar so no action for you. However my opponent argued that the wording "During the Perform Action step, the ship can perform only the [Focus} action." actually allowed his ship to do an action it wouldn't normally have. I know there is a few examples of upgrades allowing ships actions that aren't on their action bars, Afterburners for example, so couldn't point to a definitive rule to dissuade him.
Though an Ionised droid pilot thematically should be more distracted than a organic pilot!
So what should it be, no action, focus, or calculate?
