FFVI: Divergent Paths

Most of the questions you are asking are covered in the PDF manual or the various readme files.

1. Wounded soldier does not show up until after the scenarios are done. You cannot start the letter sidequest unless you have Leo in your party.
2. Chainsaw is freely available for purchase in the WoR. The Debilitator is the special Tool that you get in Zozo, and it is unbreakable.
3. All characters have the same limit, but I changed the animation. Everyone now uses Terra's "Riot Blade".
