it depends, i get alot of the "brilliant blood", that makes smiths try to impress me, i also see alot of the Wolfbloods, which makes my character tend to keep hunting dogs, the other ones are usually kinda rare. Sometimes i will get lucky and see an oddball in there, but usually if i keep reverting saves and accepting the event, itll stay on a particular few, but if i revert to say before the last "duel", it will change it up, and if i change certain traits it definitely changes which occur most often, either that or im just insanely unlucky.
