Thirst for Knowledge

Skill magazines are randomly lying around the place in various places - including repeatedly in some of the bandit camps you'll encounter on planets.

They are flat rectangular paper (or paper-style) magazines with a picture on the front, and picking up each one grants some kind of minor permanent stats bonus.

The first and most obvious is on the railing behind Sarah when you first enter the Lodge - its also visible in the loading screen image of this same scene. Just look slightly to your left (her right) as you approach.

Keep an eye out for these as you play the game, including when exploring POIs, and eventually this will unlock. They're almost always on a desk or table. You can check progress in your character's stats pages.

Progress does carry over into NG+ so don't panic about getting them all before proceeding.
