1. How are they obtained?

2. What are the benefits of having one?

3. What are the special features that are unlocked when having one?

Thanks :)

1. You can purchase them from the Cash Shop or from another user.

2. There is a list of benefits here.

3. See above. (:

You can buy them at the Cash Shop or from user shops.

With a GA, you get 5 more pet slots (up to 10 without using the mystical plushies in the cash shop), you can do 10 more of each quest each day (excluding Item Hunter), you gain access to the GA forum, you can play random every 1.5 hours, and... um... I think training cost is reduced? Oh yeah, and you get the autopricer, which will price your shop for you once a day :)

Autopricer and extra quests are the main reasons people get GA's. I'd recommend getting one at least once to see if you think it's worth it. And to get 10 pets :)

Thanks Gunblade and Spooky! That helps a lot! :D
