I laughed too as I was writing it, omg. He was like "Glad you got the real cloak, I'm out." So you can choose to chase the illusion, falling for it, and harm it (I didn't think Aruna knew any offensive magic yet, but that's up to you... oh wait she has the scissor blade), realizing it's an illusion, then get back to the real Praxis before he can even react far enough. He'd use his natural speed but of course it's no match for her short bursts. XD
