"Sure," Magnus says. "Hey Jack. Wanna show off for Bichen?"

"Do I ever," Jack says, doing a little swoop in the air.

And then Jack attacks Magnus in earnest. Magnus parries, carefully and effectively, striking back when he can. It's weird, to fight an opponent without a body. Usually during Battle Practice it's so easy to tell what to do -- you can read it in their body language, or sic sword at them while you try and hide, or take someone out of the equation by stabbing them. With Jack, all he can do is protect his own body and try and knock Jack off-balance. And Jack is one of the best swords in the world, so this is no mean feat.

So Magnus is very pleased to be able to hold his own, even if it does involve taking a few... unconventional stances and moves.
