Oh see i think i misunderstood your design goal.Trying to use it as a 'progress tracker' like how incestuous tension works. I was hoping to have this stat when a NPC generates to be set at zero for that reason.
I thought you wanted to set all the character stats to 0. Heck i might still be misunderstanding exactly what you are trying to do with this mod but in general if you wanted to have a mod that created a permanant actor then set their stats that much i know can be done. I can't be sure about creating a custom stat though.
