Teleportation Scripts are to be shared, right?
Paper costs a fraction of one energy per sheet.
Writing a Teleportation Script costs exactly one energy.*
Leaving them in partially (or totally) hidden spots: priceless.**
* Plus being in a place that's cool enough to warrant teleporting to. I figure that pays for itself.
** Well, it doesn't actually cost anything, except maybe the small number of seconds it takes to drop it.
