Comprehension is a Fallout 2, Fallout 3, Fallout: New Vegas, Fallout Tactics and J.E. Sawyer's Fallout Role-Playing Game perk.

Fallout 2 and Fallout TacticsEdit

Fallout 3Edit

You gain one additional skill point whenever a skill book is read. However, points gained from books before selecting this perk are not doubled.

NotesEdit

There are a total of 324 skill books in Fallout 3. With this perk, you can potentially increase the effectiveness of all 324 skill books by a factor of two, changing the potential skills increase of 324 to 648 skill points when all books are read. This, combined with the fact that two types of skill books respawn, can mean a potentially infinite number of skill points available. You cannot raise any skill above 100.

Books that respawn are Big Book of Science (from the Ant Researcher in Shalebridge) and U.S. Army: 30 Handy Flamethrower Recipes (from a raider using a flamer in Bethesda Office East).

Fallout: New VegasEdit

You gain an additional skill point for reading a book (for a total of 4 instead of 3), and double the temporary skill points from magazines (for a total of 20 instead of 10). There are 52 skill books in New Vegas (64 if you have Dead Money and up to 72 with Honest Hearts if you are patient enough to reload many saves outside caves with a Workbench crate). As in all other instances of the Comprehension perk, it will not affect books and magazines read prior to selecting this perk.

J.E. Sawyer's Fallout Role-Playing GameEdit

You pay much closer attention to details when you are reading. You gain 50% more skill points when reading skill-increasing books.
