Gamestage Books Mod is a Crafttweaker addon that generate books which unlock gamestages. You can set things like what color the book should be, and what item it should display as a header when the book is used to unlock the stage.

Gamestage Books is a modification exclusively for pack creators or server founders, as the mod adds scenario books. In them, you can write a survival script or the order of obtaining items and sending rewards for it.
How to use:
Put all of the books in a separate script. The first line must be #loader gamestagebooks This ensures that the script is during preInit, so that items & their models can be properly registered.
Script example:
#loader gamestagebooks
import mods.gamestagebooks.Book;
Book.addBook("emerald_stage", "Emerald Knowledge", "Emerald Handbook", "minecraft:emerald", 0x0cf200);
- Stagename -> “emerald_stage”
- Human readable stagename(used in unlock title) -> “Emerald Knowledge”
- Name of the Book -> “Emerald Handbook”
- Item to display on unlock -> “minecraft:emerald”
- Item to display on unlock with meta -> “minecraft:wool@4”
- Color of the book -> 0x0cf200
- Color is a hexvalue prefixed with 0x
