Fallout Tactics skill books

General information
Skill books in Fallout Tactics can be used to increase a character's skill in specific areas of study. After a book is used, it is removed from your inventory.

When reading a book, you get up to 15 skill points, depending on your current skill level, and whether it is a tagged skill. Number of gained skill points decreases by one point every three skill levels, starting from 107 (for tagged skills) or 72 (for non-tagged). For example: if you read a skill book for a tagged skill while already having 106 or 107 points in it, you will end up with that skill at level 121 (gaining 15 or 14 skill points).
