As soon as you enter Agrabah you’ll find Aladdin in trouble with some Heartless. Clear them out and you’ll receive the Key of Beginnings . You don’t have to go far, just clear the room and enter the Room of Beginnings. After a quick scene you’ll obtain the Key of Guidance . You’ll need to travel through a few rooms before reaching the Room of Guidance, so take the time to level up while traveling.
You’ll have to fight off more Heartless in the Room of Guidance, but you’ll receive an Ether for your efforts. Another event occurs and you receive the Key of Truth . Head back to the starting room and enter the Room to Truth for a boss fight.
BOSS - Jafar-Genie
Jafar is one of the easiest fights in the game because all you need to do is chase down Iago and hit the lamp. Jafar will toss boulders and fireballs at you, but it’s simple to switch to a 0 card and card break the attack. Jafar attacks very slowly, so focus on finding Iago and locking onto him, then worry about the card level that Jafar is using against you. The Gimmick Card in this battle will stop the platforms from moving and raise them to the maximum level so that you can hit Iago without needing to jump. Beat him for a Jafar-Genie Enemy Card.
After the scene you’ll receive a Genie Card . Head out to the 3F when you are ready. You’ll have a chance to save in the hall.
