Version 0.10: This article may not be up to date for the latest stable release of Crawl.

Spell books contain spells that can be memorised, if you have sufficient skills in Spellcasting and the school to which the spell belongs. They are very important, as they are the method by which spellcasters gain new spells. Spell books can be found on the Dungeon floor, bought from shops, given as gifts by certain gods, or generated with a scroll of acquirement.

Spell Book Identification and Use

Most of the time, reading a spell book is enough to identify it, revealing the spells it contains. Once a spell book is identified, you can attempt to memorize any spells it contains, provided you have free spell levels and high enough magical skills to handle the spell in question.

However, a few powerful spell books require you to have certain magical skills, or they will be "beyond your level of understanding," preventing you from identifying them:

For followers of Trog, identifying a spell book will decrease the piety gained from burning it.

Spell Book Destruction

Advanced magic users often need to change their spellsets. Scrolls of amnesia allow them to forget any spell and recoup the spell levels to learn a different spell. However, these scrolls are rather rare. Conveniently, spellbooks can also be used to this effect, however you are limited to forgetting one spell contained therein, and the process destroys the spellbook itself. (Followers of Sif Muna never need to do this because they are granted this ability after sufficient piety.)

Strategy

Spell books are not exactly rare, but there are a great many of them. They're also rather expensive in shops. Thus, obtaining a specific spell book that you want can be a hassle, but you can alleviate this by worshiping the right god.

Sif Muna, Kikubaaqudgha, and Vehumet all grant spell books as gifts, weighted towards spells/books you don't already have. Sif Muna is the most generous in this regard: since the types of spellbooks granted depend on magical skills, you can influence them by training specific skills, and thus raise your probability of getting the most useful spells for your playstyle. Followers of Sif Muna will eventually have access to every spell in the game this way. Meanwhile, Vehumet is more straightforward and probably the best choice for novice players, as he grants piety for killing monsters, and his gifts include the most powerful Conjurations and Summonings spell books in the game. Finally, Kiku only grants Necromancy-related books (including the Necronomicon), making him in some ways better suited for Necromancers than other spellcasters; on the other hand, he grants the four major Necromancy texts in order, so he's a good choice for training up Necromancy from scratch. It is also worth noting that Kiku starts granting his books much sooner than Sif Muna or Vehumet.

Note that you keep your gift books even if you abandon your god. Some advanced players take advantage of this, serving Vehumet or Kiku until they get the rare books they want (and can survive their divine retribution), then leaving them for another god who offers further powers.

Followers of Trog, who shun spellcasting, can burn any visible spell book as an ability. This not only scores piety, but the flame cloud generated will remain for several turns afterward, potentially blocking or damaging monsters (especially if they were standing on the book when you detonate it). Note that no monsters avoid spell books on the floor or see them as a hazard at all, making it easy for you to use your books like land mines.


List of spells by book

Main article: List of spells by book

The following are all standard spellbooks in Crawl. If you find any book other than the ones listed below (often with exotic or ridiculous names), it is a randomly generated artefact spellbook. Randart spellbooks have no set contents but may often contain just the spell you were looking for.
Please do not add randart spell books to this list.

History

Starting in 0.10, Spellcasting was trainable without first having to "exercise" it to skill level 1 via reading spells.

These spellbooks were removed/made obsolete, as of 0.9:
