Place the device.
Still worried about Xion, Roxas is deeply troubled and begins questioning himself about who he really is. Nevertheless, he is sent on another mission, this time to Agrabah to plant a device.
Defeat Heartless in every room while traveling to the Lamp Chamber. Once at the Lamp Chamber, Roxas sets up a device in the chamber on behalf of the Organization. However, two Scarlet Tangos and a Land Armor appear in an attempt to destroy the device. To move on Roxas must defeat them. The Heartless battle shouldn't be that hard, but watch out when dealing with the Land Armor. The Land Armor is highly susceptible to Aero magic. Limit Recharges, Potions, and Cure Magic are a good idea. Whittle away at its HP until you are victorious. After the battle is over, Roxas will immediately RTC in Mission Mode. There is an optional Invisible to face in the Secret Depths area. Jump up to the highest platform and it will appear. It is extremely weak against Fire Magic, but Thunder Magic will cure the Heartless.
