Kingdom Hearts Final Mix

For this trophy you must defeat Kurt Zisa who appears at Agrabah in the Desert. You have access to this optional fight after you have locked the keyhole at Hollow Bastion. To trigger this boss fight, head to Aladdin's House and speak with a panicking Carpet who will bring you to Kurt Zisa.

When you can go ahead and summon Tinkerbell, she will be a great asset in this fight during certain phases the boss goes through. The boss alternates between two states, one where he has anti-magic orbs out restricting you from using magic or even items so you are limited to physical attacks and Tinkerbell for life, then a state where he protects himself inside a magic barrier. In the magic barrier he can only be hurt with spells, if you are in need of MP you can use physical attacks to make him drop MP balls as he floats around.

After doing enough damage during each state he will be stunned and fall to the ground where you are free to attack him. Repeat this multiple times and this should be an easily won fight.
