Am I supposed to delete what's in the post battle section and replace it with this or do I just tack this on after the last line in the post battle section
Never! Delete something out of program code if you don't 100% know what you are doing or you can not revert bugs anymore.
You look for the lines that I typed in the script and
Put a // at the start of the line.
So that instead of for example
Repairdurability.this;
Or whatever, you get this
// repairdurability.this;
This way programmcode in that line will not be executed.
Also: battle is just this slow, I actually edited my files to skip the blowbang scene, because after the third time it gets boring and it just takes 15 minutes of waiting and pushing x space every 15 seconds.
Wish for normal battles there would be a struggle or a skip x turns command
