When you Free a Lord, When you have a Persuasion and the Lord defect his actually fraction (Both give 20 points in calculating)
Here the methods:
public static void OnLordFreed(Hero targetHero)
{
TraitLevelingHelper.AddPlayerTraitXPAndLogEntry(DefaultTraits.Calculating, 20, ActionNotes.NPCFreed, targetHero);
} Edit: This method wont actually be used by other code so i think it will not work
public static void OnPersuasionDefection(Hero targetHero)
{
TraitLevelingHelper.AddPlayerTraitXPAndLogEntry(DefaultTraits.Calculating, 20, ActionNotes.PersuadedToDefect, targetHero);
}
