The book texture that is displayed is based on these groups in the order listed:



1. Curses

2. Mutually Exclusive Enchantments (Books with gems)

3. The General category (Books with the original red ribbon)

4. All other book categories



Should there be more than one enchantment from one of the groups listed above,

the texture is selected in alphabetical order.



Examples:


You have a book that is enchanted with Silk Touch, Luck of the Sea, Flame, and Curse of Vanishing.
For this book, the highest group present is group 1 with Curse of Vanishing--Curse of Vanishing would be selected resulting in a black cover with the original red ribbon.

Next, if the book is enchanted with Silk Touch, Luck of the Sea, and Flame, and Curse of Vanishing the highest group present is group 2 with Silk Touch being mutually exclusive--the texture for Silk Touch will be chosen resulting in a black ribbon and a light blue gem.

Finally, let's say the book has only Silk Touch, Luck of the Sea and Flame. , and Curse of Vanishing.
For this book, the highest group present is group 4 with both Luck of the Sea and Flame. Because they are from the same group, the enchantment selected will be Flame through alphabetical order--resulting in a yellow ribbon.
