Hm. That's probably how I would do it here, too. Like I said, I've just had them 'guided' anyway even without system assist before, so it wouldn't be a problem. It's technically their ability anyway, so there's no reason it wouldn't be able to work the same way in a different setting (for the sake of roleplay.)

Aah, this is really making me want to play Heathcliff again. Do you play any others from SAO?
