Bookmaster

Replacing the Wizard enemy from the original game, Bookmasters (ブックマスター) are Emblem Heartless that appear in Kingdom Hearts II. They're close relatives to the magic-using Heartless such as Crimson Jazz. Like their predecessor, Bookmasters first appear in Hollow Bastion.

Bookmasters can use all forms of magic other than Magnet, Reflect, and Cure. They can also hit you with their book, which appears in a Japanese fashion based on its cover side. This attack is hard to deflect. Their magic hits from quite a distance, so it's best to use physical attacks.

There is a small chance that defeating a Bookmaster will reward Goofy with the Akashic Record weapon.

A more powerful version of this Heartless, called Runemaster, appears in the Cavern of Remembrance in Kingdom Hearts II Final Mix.

Design
A Bookmaster is a rather small Heartless that wears long robes that cover its feet. These robes are predominantly green, with a yellow collar, white highlights, and a blue bottom. It also wears a tall, cylindrical, green and white hat and what seem to be orange gloves. The only part of the Heartless not covered by clothing is its blue, spherical head and yellow, glowing eyes. All Bookmasters hold a book known as the Akashic Record.

In Kingdom Hearts II Final Mix, a Bookmaster wears predominantly yellow robes with an orange collar and brown patterns decorating them. Its hat is yellow and brown, and it carries a differently-colored version of the Akashic Record.

The Bookmaster's name is an obvious reference to the spell book it carries and fights with, and its skill in using it.

Strategy
The Bookmaster is immune to all magic attacks excluding Reflect and Magnet. It attacks from a distance using Fire, Thunder, and Blizzard. Using Reflect or Guard to defend these attacks is a good strategy; if you have Reflega, it can take out several Bookmasters at once.
