Please note that when you are outside Zexion's book world, you can't take damage. Although Sora's icon looks like he took damage, note that his health doesn't go down.

Dodge Roll is your friend of you're attempting no magic. The first time that he takes you to the book world, find the book that's homing in on you, that one is Zexion. Dodge Roll into him and combo him. I highly recommend and Air Combo Plus and Horizontal Slash for this fight, as it will make it incredibly easy to damage him in and out of the book world.

The reason that I got lucky is that 99% of the time, Zexion traps you in his book again, and that's when he's the most difficult to fight. I, however, didn't have to do this, which made the battle go a lot smoother.

The desperation move is ridiculously easy to dodge. The floating book will change it's location 13 times, so it's always predictable. Count how many times it changes location, then on the 13th, prepare to Dodge Roll into a circle. If you miss it, you fail, since you will die outside of the barrier.
