Upon completing the finale quest Whatsoever a Man Soweth..., this achievement will unlock.
To begin this quest, you must have completed the previous main quests:
Evil's Soft First Touches
Dead Man's Party
Open Sesame
Open Sesame: Witcher Seasonings
Open Sesame: Breaking and Entering
Open Sesame: The Safecracker
Scenes From a Marriage
NOTE: I have linked each Hearts of Stone achievement that is tied to a main quest as all of them - apart from I'm Not Kissing That - are missable.
