I know.
1. Edit Character.xlsm
2. Run Generate All in All.xlsm
3. Open up Character.txt
4. Find different stats as per Character.xlsm
But why.

I'm trying it again now. Well, just editing the txt directly.
EDIT: Think I could add this into a mod that I could publish to Steam to get it up there? Like, make an empty mod through editor, add files to the mod folder, publish to workshop? Would it pack in the added files, you think?
EDIT2: I just realised I forgot about a different issue.
I tried opening SkillData.xlsm once, but OOO would freeze upon loading and leave the locked file thing.
I'm not sure on how Open Office works, but might it be that it's locking that file and thus unable to interact with it, resulting in these odd results?
EDIT3: Removing the lock file thingy doesn't change anything.
EDIT4: I've corrected the Character.txt and SkillSet.txt to no avail. Once I reach the characters in-game, their stats are reset to the odd mix-match of my edit and vanilla, with bugs. I dunno, just on steroids. Madora gets 1 speed, all of the sudden.
