History is a passive skill in Pillars of Eternity II: Deadfire.
A broad skill, history covers the commonly-accepted narratives of Eora's civilizations and how they came to be. As this skill draws from many sources, a measure of folklore has been woven into many stories.
As with other passive skills, History is only used during conversations and scripted interactions, and otherwise has no effect on gameplay or combat mechanics whatsoever.
