The Grimoire Generator is a free Dungeon Master tool to help you generate titles for magical or esoteric texts. There are options for generating prices and rarity based on the D&D 3.5 system resource document spell list, and an option for including cosmically horrific descriptions. You can even search the library with your own custom locations or topics. Please use the books you generate however you like!
If you generate any gems, or if you have any feedback, requests or suggestions, leave them in the comments section at the bottom of the generator page.
