Ack, also missed this post earlier.

I overlooked The Weeper being able to recover that fast. It seemed fairly drawn out in your wording, but Mikael was also knocked back a further distance than him, so it adds up.
He does charge the spheres pretty quickly, but yes, not quite that fast. It may still have made sense if I had Mikael charge the second sphere while flying back from the first, as I had planned... but apparently I didn't write that. That right there's probably thrown the match already, since he'll have to be a whole lot more reckless now. Hopefully this edit suffices.

For the record, The Weeper's sword would probably slice open Mikael's spheres (though that would be bad for both of them), and a few direct shots could destroy a smaller sphere. I don't think there's any risk of this ability causing a stalemate.
