Skills can be used outside of combat for a variety of purposes and they grant auxiliary combat bonuses. For a detailed list of skills and their effects in the games, see the above articles.
Overview
In Pillars of Eternity the five skills are Stealth, Athletics, Lore, Mechanics and Survival. Every class gains initial proficiency bonus in two skills, but not limited to them. Non-combat skills are gained separately from combat skills(Abilities, Talents) and they do not use the same resources.
For Pillars of Eternity II: Deadfire a large expansion to the skill system has been announced. Many passive skills for dialogues and scripted interactions will be added – such as Religion, Metaphysics and Streetwise; points will be gained separately for active and passive skills; the player character will benefit from companions' skills[1]
