During the game your comparity with your father will be wiped out because of the princess. In order to get a special weapon from the father which is the cards you must give stupid answers to everyone u encounter except the father. When the realation ship with ur father slips trade the items u get, starting with the grandmother and work your way till u get a broken gun. Its known that a famous hero used it. You will extange it for a unicorns horn and the realiton ship. Go to the teller and see if u got a relation ship with dad. If so go back to him and he will give you the cards. It happened to me so It should help u to.
