Give Rescue a second charge.

I wouldn't be surprised if there is something with this engine that makes it incredibly hard to implement

Correct me if I am wrong, but didn't Shukuchi used to be a real teleport? I been told it used to be, and there is even a moment in the NIN questline(I believe in StB?) that tells you to use Shukuchi to cross a gap between rooftops, but attempting to do so will cause you fall to street level, and it is just not a big deal cuz you can just jump across, if that's correct, what it tells me is that gap closers being movement rather than teleport is a deliberate choice, likely to avoid cheese strats by abusing it, rather than a limitations of the system.

Of course, "no teleport to avoid cheese" would also mean no teleporting Rescue, so eh.
