How powerful do the electrical shocks need to be to disable the droids? ... basically I'm just double-checking that even at half-power Ryoji using a powerful electrical spell would be able to actually take at least some out.

Also, how difficult is it to behead a shift hunter?

Really I'm just trying to get a good gauge on how effective he'd be... Obviously, he can't last indefinitely, and he can only really deal with stuff close by him, but it's more a matter of how much can or can't he actually deal with.
