Ken Follett's The Pillars of the Earth

During the passage of the third chapter, playing as Jack, you will need to demonstrate to Martha three times your ability to wield a sling, and subsequently, already in the sixth chapter, give this weapon to the girl. To do this, use the sling on Martha at least three times, after each story dialogue in the third chapter, and successfully complete the mini-game that follows.
The trophy will drop in chapter six.

The trophy drops in Chapter 5 after giving the sling to Martha
