At first I was cursing the game for not having hotkeys, as it was difficult to cast meteors quickly enough to kill champion ninjas. But I just realised you can hold shift to quickly cast multiple meteors which makes a HUGE difference in getting the hard badge. Once fully skilled up you can cast 5 meteors in a row which kills a ninja outright. Please rate up this comment to keep this info visible.
