Basically, just make put *stat_chart in your choicescript_stats text file.
The stats will be accessible at any time for the player to see. The only time they wouldn’t be would be if you put an *if statement in your chart.
For example:
*if (magic = true)
percent magic
So, if “magic” was set to true before, it would show you the percent magic that the player has. Otherwise, it wouldn’t show up at all, at least until the condition was made true.
