Like I've said, I'm perfectly fine with higher-level features being supernatural of some variety (though I think flavor-wise, "psionics" fits better than "magic" for something based in enlightened discipline). I'm thinking something halfway between the Fury and the Null: about as much supernatural stuff as the Fury, but flavored more like that of the Null. The main issue I see with it is that it runs the risk of just being "Null with a sword", but that's something a competent game designer (i.e. not me) could work out.
