Like crafts, hobbies can be fun activities that give you a break from adventuring. Hobbies generally require little initial investment (as opposed to crafts) as you only need the tools of the trade to begin. With the exception of chocobo digging, there is no "skill" invovled with hobbies, only set ways to perform. Harvesting, Excavating, Logging and Mining (H.E.L.M.) only require you to buy the appropriate tool, and trade them to targets in monster infested areas. Gardening requires pots and the assistance of your moogle, and takes place in your moghouse (though your moogle does most of the work). Clamming takes place in one location, and is part of a game that can net you a good deal of loot, or lose it all if you overload your bucket and break it. Lastly, chocobo digging requires only that you hop on a chocobo, and feed it treats to get it to dig in any zone your chocobo can travel to.
Using a pickaxe, you travel to the deep dungeons and boneyards to find hidden buried treasures. You pick through the buried bones of animals and great beasts long past their prime. Materials you obtain are most often used in bonecraft, and various other crafts as well.
With the help of your Moogle, you plant seeds and tend to them, hoping to grow fruitful results. Gardening takes place in your mog house, using pots and seeds, and can give various results, depending on species and how you care for them. Materials you obtain from gardening are most often used in cooking and goldsmithing.
Using a bucket and shovel, you travel to the islands off the coast of Bibiki Bay. Here you play to see how much you can fit in one bucket without it breaking. Materials you obtain are used in a variety of crafts, or can be sold directly to a merchant for profit.
Using bunches upon bunches of gysahl greens, you procure the use of a chocobo and head off to see what you can dig up. Chocobo's will gladly dirty their beaks for taste of these greens, and you can dig up quite a variety of items. Materials you obtain are varied, and depend largely on the area in which you are digging.
Multiple Hobbies and Hobby Bonuses
There are no limits to the number of hobbies you can participate in. Multiple hobbies may require lots of inventory and/or mog house space, so be prepared. All hobbies have armor sets that give bonuses to certain aspects of the trade. The only exception to this is gardening, which instead is allowed to have a moghancement instead:
