Books and Enchanted Books

• Amethyst Book: crafted with 8 Amethyst Shards and a Book. Only Amethyst Books can be enchanted.
• Enchanted Book: disenchanting one of those will give back a regular book, so you will need a lot of amethysts if you're going to cycle through different Enchantments on an Enchanting Table.
