Wow! how did I miss that for like forever! Never mind then, magic missile does work (except maybe when the fighter uses the total cover to then hide. But that's a piece of raw I refuse to use)
So basically for wizard we're looking for: A way to fly at lvl 1 without being an anthropomorphic animal.
For fighter we're looking for: A way to get nerveskitter or any other usefull way of spending an immediate action (Quertus mentioned this being a possibility, I'm not aware of any).
And just in case we do find a way for the wizard to get airborne: a way to combat magic missile? I don't know of any.
