Also to Arkone and Loserishome, please don't be discouraged to add more secrets just maybe a little more tips/hints would be nice to have in-game. Love the game and the concept so far!
You need one of the spirit stones (Warrior Spirit Stone or Mage Spirit Stone or Archer Spirit Stone). You can get them from the blacksmith under Create Items. Then you fight some monsters after using one of the stone to advance the pregnancy.
