thanks tsf4! Wow, this was actually one of the easiest mod I have done.
Now there is no need for endless search for good wife for you or your son because the perfect one will be right there waiting for you in the forest. Chose the hunting focus and win her heart!
Meet the new, perfect wife material through hunting focus, who is midas_touched, gardener, genius, strong, fair, shrewd and kind with guaranteed base stats of 10.
Just in case anyone wants to do the same here is what I did.
Go to the event folder in your own mod folder.
Check out the wol_hunting_events.txt
look for event number 5065 or just type in elusive_shadow.
This will lead right to the female character, or male if you were playing as female, that appears during the hunting focus.
Change her traits and stats to your whim. I changed her education trait from intrigue to stewardship because I care about income and demesne limits but you can change it to martial or learning for stonger army or tech advantage. and you are done!
