Skill (Max Points) – How to get
Story books allow you to start a quest, and that quest ends up in you getting that skill
Skill Books (advanced charged blow only for paladins) are untradable but automatically give you the skill. You can use Scissors of Karma though.
The other ones are in these books (Mastery books i think, not sure) that have a % chance of working, and are dropped by mobs and are tradable. to pass a skill (20) book you need a certain amount of points (i think its 8) in the skill and to pass a skill (30) you need 15 (i think) points in the skill.
