The Bard's Tale IV: Director's Cut

To obtain this achievement, you must complete a side quest that is taken from Wilfreth's father in lower Skara Brae. He is located in the camp next to the first tavern you come to in the story. You can complete the quest at the Beida Valley location in the south/southwest of the village, where you will need to kill the paladins and take the relic from the chest and take it back to lower Skara Brae. After completing the quest, you can choose which character to open a new skill branch (Saint), and by leveling it up, a trophy will drop.
