Hi, I'd like to share some information about 2.1 that was not officially disclosed in the live letter. This info is mostly surmised from multiple hints/clues and old beta information. If you have more to add please post it!!

Treasure Hunting:

Treasure Hunting is also known as Chocobo digging. You will harvest items with your chocobo. it is mainly a farming activity. All classes will be able to participate in various ways. Gatherers seem they will be getting the most content relating to this.

There are 3 gatherer instances: Chocobo Mine, Chocobo Lagoon, and Chocobo Forest

There will also be chocobo levequests for combat classes

The main purpose of this activity is to gather materials. You will also get Chocobo Points (Beta name) for participating.

Chocobo points can buy several items of note :
Astral Vision 100,000 CP = Allows you to gather Astral materials in chocobo digging
Adamn ingot 50,000 CP = Used for the new relic weapon.
