During the game, you'll have some opportunities to boost your attributes and skills outside of initial character creation and leveling up.
- There are 20 Vault Boy bobbleheads stashed across the wasteland. Each one is associated with a unique attribute or skill. Find one, and it will either boost an attribute by one point, or a skill by ten points.
- There are books in the wasteland that boost a skill by one point. There are 25 books for each skill, and you will come across quite a few of them without even trying. There is also a perk that will double the number of points you get from each book, so you can potentially boost any skill by 50 points just by finding these books.
- Occasionally, you can receive some kind of item or effect that will permanently boost a skill by either completing a quest or helping an NPC.
- There is equipment that will boost attributes and/or skills, as well as derived statistics, for as long as you are wearing them.
- There are drugs that will temporarily increase your skills, derived statistics, and/or sometimes even attributes.
