It's not. Magic duel is 1d6+base astral, and the roll isn't open ended. With 6 a tie is still possible, 7+ and you're 100% safe from s1 mages. But beware those s2s still, and even with 9 an s3 could do you in.
That said, I kinda doubt anyone's going to send a precious s3 mage (or rather, a dozen of them) to attempt a do-or-die trick that only works 1/36 times... unless they have nothing else to lose of course.
