When making a custom skill, the simplest method is to just copy/paste an existing skill and modify it slightly.
That's all well and good, but what if you wanted to know what possible options that you could use for such entries like the "Icon" or "TargetCastEffect"?
Sure, you could look at the SkillData for other skills. Or you could look at this Excel spreadsheet that I made that contains all of the values used by the Main SkillData.txt sorted by the Data name (Note: It contains the values peicewise, completely separated from the Skills they originally came from)
Picture of the Spreadsheet in action:

Note: This spreadsheet only includes the values actually used by existing skills, and is thus a non-exhaustive list of possible entries. A data entry might accept any Integer, for example, even if the numbers {1, 3, 5} were the only Integers used by the Main SkillData.txt.
