April 7, 20215 yr Non-class skill books are expert skill books which any class can use. Although, unlike ordinary expert skill books, these skill books can not be upgraded. Most of them grant only small improvements but few of them are actually quite powerful. At the moment, there are 73 non-class skill books, 70 of which are passive and three that are active. The only requirements to use these books are a character level of 18 and an empty combat kit slot which means that these books won't consume the space meant for normal expert skill books. Every character has 15 combat kit slots in total, but there is no limit to the number of books a single character can have in an inactive form. Non-class skill books can be obtained by killing raid bosses, participating in guild events and completing dungeons during seasonal special events. Some books can also be obtained from physical chests that require special keys. Non-class skill books are more than rare but they are also worth of millions which means that if you ever happen drop one and sell it, you won't have to worry about gold for a while. This guide valid for the game version of 13.3.3.

Type: Active Energy expense: 50 units Cooldown: 60 seconds Drops from: Gladiator's Chests (these can be bought with Arena Points) Notes: This book is personal which means that it can't be given to other players. If you don't need this book, you can sell it to an NPC and receive 10000 gold. If you drop one of the passive skill books, you must decide, will you use it, sell it or trade it. It all depends on how much gold you really need. Everyone needs gold but do you feel like you are weak and can never buy any proper equipment due to the lack of gold? If so, then you should sell it as 2.5 % stun or 3 % critical hit chance won't really make you any stronger but good armor and weapon will. If you already have decent gear and you are not in the constant need of gold but your gear isn't +10, then you should think, will the book raise some parameter that you really need or can you even use the book properly? For example, the Book of Rampant Attack might not be the best choice for a druid and the Book of Secret Power of Vampirism might not be the most useful book for a character with 3500 hp. If the book is useful, then you can use it but if it's not, then you could either sell it for gold or trade it for a more suitable book. This is the end of this guide! I hope this will be useful to you. Edited May 10May 10 by Phosphatase Updated to the game version of 13.3.3
