Excavation minigame

The Excavation Minigame is from Final Fantasy X-2, and can be done in Chapters 1, 2, 3 and 5. The game consists of Yuna looking for hidden treasures in various parts of the Bikanel Desert.

To initiate the digging sidequest you must visit Djose Temple in Chapter 1. Keep talking to Gippal and answer "We're sure" when the option comes up, and he will give you the "Letter of Introduction" Key Item. This will make Bikanel a Hotspot when you go back to the airship.

Once this is done, you will need to go to Bikanel and talk to Nhadala. Doing this in Chapter 1 will have her send you on a mission to do some digging. Chapter 2 she will send you to the Oasis to investigate some suspicious activity.

Digging
You will be given 1 minute to find a yellow cross on the map, and dig up the Mission Critical Item. These will be either an assembly piece, which will affect the strength of the Experiment in Chapter 5, or a piece of Scrap Metal. There will also be 4 white crosses on the map. These will either give you an item, or will initiate a battle.

Once you have uncovered the yellow cross treasure, you will need to get back to the hover before the time runs out. If you do not make it back, Yuna will collapse of dehydration and you will fail the dig. In the Westerm Expanse and the Central Expanse you will also have to compete with other diggers for the treasures in the desert, so you need to be quick.
